Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	2. Summary of significant accounting policies Basis of presentation The accompanying unaudited interim condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) and include the accounts of the Company, its wholly-owned subsidiaries and consolidated Variable Interest Entities (“VIE”). These interim condensed consolidated financial statements are stated in U.S. dollars, except where otherwise indicated. Intercompany transactions and balances with subsidiaries have been eliminated for consolidation purposes. Substantially all net revenues, cost of net revenues and operating expenses are generated in the Company’s foreign operations. Long-lived assets, intangible assets and goodwill located in the foreign jurisdictions totaled $ 552,837 thousands and $ 490,464 thousands as of March 31, 2021 and December 31, 2020, respectively. These interim condensed consolidated financial statements reflect the Company’s consolidated financial position as of March 31, 2021 and December 31, 2020. These consolidated financial statements include the Company’s consolidated statements of income, comprehensive income, equity and cash flows for the three-month periods ended March 31, 2021. These interim condensed consolidated financial statements include all normal recurring adjustments that Management believes are necessary to fairly state the Company’s financial position, operating results and cash flows. From the quarter ended March 31, 2021 the Company disclosed Net product revenues as a separate line of Net revenues following its growth in significance relative to Net service revenues. As a result, the Company has reclassified the corresponding amount of the three month period ended March 31, 2020 to the line Net product revenues for an amount of $ 12,199 thousands for comparative purposes. Because all of the disclosures required by U.S. GAAP for annual consolidated financial statements are not included herein, these unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2020, contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). The Company has evaluated all subsequent events through the date these condensed consolidated financial statements were issued. The condensed consolidated statements of income, comprehensive income, equity and cash flows for the periods presented herein are not necessarily indicative of results expected for any future period. For a more detailed discussion of the Company’s significant accounting policies, see note 2 to the financial statements in the Company’s Form 10-K for the year ended December 31, 2020. During the three-month period ended March 31, 2021, there were no material updates made to the Company’s significant accounting policies. Revenue recognition Revenue recognition criteria for the services provided and goods sold by the Company are described in note 2 to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. Contract Balances Timing of revenue recognition may differ from the timing of invoicing to customers. Receivables represent amounts invoiced and revenue recognized prior to invoicing when the Company has satisfied the performance obligation and has the unconditional right to payment. Receivables are presented net of allowance for doubtful accounts, loans receivable and chargebacks of $ 176,912 thousands and $ 126,661 thousands as of March 31, 2021 and December 31, 2020, respectively. Deferred revenue consists of fees received related to unsatisfied performance obligations at the end of the period in accordance with ASC 606. Due to the generally short-term duration of contracts, the majority of the performance obligations are satisfied in the following reporting period. Deferred revenue as of December 31, 2020 and 2019 was $ 32,519 thousands and $ 16,590 thousands, respectively, of which $ 9,413 thousands and $ 5,562 thousands were recognized as revenue during the three-month periods ended March 31, 2021 and 2020, respectively. As of March 31, 2021, total deferred revenue was $ 18,556 thousands, mainly due to fees related to listing and optional feature services billed and loyalty programs that are expected to be recognized as revenue in the coming months. Digital Assets During the first quarter of 2021, the Company purchased an aggregate amount of $ 7,800 thousands in bitcoins. The Company accounts for its digital assets — bitcoins — as indefinite-lived intangible assets, in accordance with Accounting Standards Codification (“ASC”) 350, Intangibles—Goodwill and Other. The Company has ownership of and control over its digital assets and uses third-party custodial services to store its digital assets. The Company’s digital assets are initially recorded at cost. Subsequently, they are measured at cost, net of any impairment losses incurred since acquisition. The Company performs an analysis each quarter to identify whether events or changes in circumstances, principally decreases in the quoted prices on the active exchange, indicate that any decrease in the fair values of the digital assets below the carrying values for such assets subsequent to their acquisition will result in a recognition of impairment charges. The Company determines the fair value of its digital assets in accordance with ASC 820, Fair Value Measurement. Impairment losses are recognized in the period in which the impairment is identified. The impaired digital assets are written down to their fair value at the time of impairment and this new cost basis will not be adjusted upward for any subsequent increase in fair value. Gains (if any) are not recorded until realized upon sale. In determining the gain to be recognized upon sale, the Company calculates the difference between the sales price and carrying value of the digital assets sold immediately prior to sale. Repurchase of 2.00% Convertible Senior Notes due 2028 - Extinguishment of debt The derecognition of a convertible debt is based on the principle that an entity is extinguishing the liability component and reacquiring the equity component that was recognized at issuance. This approach is applied whether the debt was settled in cash, shares, other assets (or any combination), or at maturity upon conversion or upon early extinguishment. The settlement consideration is first allocated to the extinguishment of the liability component equal to the fair value of that component immediately prior to extinguishment. Any difference between that allocated amount and the net carrying amount of the liability component and unamortized debt issuance costs should be recognized as a gain or loss on debt extinguishment. Any remaining consideration is allocated to the reacquisition of the equity component and recognized as a reduction of stockholders’ equity. Any paid premium included in the repurchase price should be recognized as a loss when the debt is extinguished. Foreign currency translation All of the Company’s consolidated foreign operations use the local currency as their functional currency, except for Argentina, which has used the U.S. dollar as its functional currency since July 1, 2018. Accordingly, the foreign subsidiaries with local currency as functional currency translate assets and liabilities from their local currencies into U.S. dollars by using year-end exchange rates while income and expense accounts are translated at the average monthly rates in effect during the year, unless exchange rates fluctuate significantly during the period, in which case the exchange rates at the date of the transaction are used. The resulting translation adjustment is recorded as a component of other comprehensive loss. Argentine currency status As of July 1, 2018, the Company transitioned its Argentinian operations to highly inflationary status in accordance with U.S. GAAP, and changed the functional currency for Argentine subsidiaries from Argentine Pesos to U.S. dollars, which is the functional currency of their immediate parent company. Since the second half of 2019, the Argentine government instituted certain foreign currency exchange controls, which may restrict or partially restrict access to foreign currency, like the US dollar, to make payments abroad, either for foreign debt or the importation of goods or services, dividend payments and others, without prior authorization. Those regulations have continued to evolve, sometimes making them more or less stringent depending on the Argentine government´s perception of availability of sufficient national foreign currency reserves. The above has led to the existence of an informal foreign currency market where foreign currencies quote at levels significantly higher than the official exchange rate. However, the only exchange rate available for external commerce and financial payments is the official exchange rate, which as of March 31, 2021 was 92.0 . The Company uses Argentina’s official exchange rate to record the accounts of Argentine subsidiaries. The following table sets forth the assets, liabilities and net assets of the Company’s Argentine subsidiaries and consolidated VIEs, before intercompany eliminations, as of March 31, 2021 and December 31, 2020: March 31, December 31, 2021 2020 (In thousands) Assets $ 1,493,608 $ 1,470,885 Liabilities 1,154,563 1,230,326 Net Assets $ 339,045 $ 240,559 Income taxes The Company is subject to U.S. and foreign income taxes. The Company accounts for income taxes following the liability method of accounting which requires the recognition of deferred tax liabilities and assets for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred tax assets are also recognized for tax loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets or liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company’s income tax expense consists of taxes currently payable, if any, plus the change during the period in the Company’s deferred tax assets and liabilities. A valuation allowance is recorded when, based on the available evidence, it is more likely than not that all or a portion of the Company’s deferred tax assets will not be realized. Accordingly, Management periodically assesses the need to establish a valuation allowance for deferred tax assets considering positive and negative objective evidence related to the realization of the deferred tax assets. In connection with this assessment, Management considers, among other factors, the nature, frequency and magnitude of current and cumulative losses on an individual subsidiary basis, projections of future taxable income, the duration of statutory carryforward periods, as well as feasible tax planning strategies that would be employed by the Company to prevent tax loss carryforwards from expiring unutilized. Based on Management’s assessment of available objective evidence and considering the future effect of the Company’s initiatives to capture long-term business opportunities, the Company accounted for a valuation allowance in certain subsidiaries in its Mexican operations of $ 12,176 thousands and $ 14,186 thousands for the three-month periods ended March 31, 2021 and 2020, respectively. On June 10, 2019, the Argentine government enacted Law No. 27,506 (knowledge-based economy promotional regime), which established a regime that provides certain tax benefits for companies that meet specific criteria, such as companies that derive at least 70% of their revenues from certain specified activities related to the knowledge-based economy. The regime was suspended on January 20, 2020 until new rules for the application of the knowledge-based economy promotional regime were issued. On June 25, 2020, the Chamber of Deputies passed changes to the knowledge-based economy promotional regime. The Chamber of Senates proposed further amendments, which were returned to the Chamber of Deputies and finally approved on October 7, 2020. The approved regime is effective as of January 1, 2020 until December 31, 2029. Based on the amended promotional regime, companies that meet new specified criteria shall be entitled to: i) a reduction of the income tax burden of 60% (60% for micro and small enterprises, 40% for medium-sized enterprises and 20% for large enterprises) over the promoted activities for each fiscal year, applicable to both Argentine source income and foreign source income, ii) stability of the benefits established by the knowledge-based economy promotional regime (as long as the beneficiary is registered and in good standing), iii) a non-transferable tax credit bond amounting to 70% (which can be up to 80% in certain specific cases) of the Company’s contribution to the social security regime of every employee whose job is related to the promoted activities (caps on the number of employees are applicable). Such bonds can be used within 24 months from their issue date (which period can be extended for an additional 12 months in certain cases) to offset certain federal taxes, such as value-added tax, but they cannot be used to offset income tax. On December 20, 2020, Argentina’s Executive Power issued Decree No. 1034/2020, which set the rules to implement the provisions of the knowledge-based economy promotional regime. Eligible companies must enroll in a registry according to the terms and conditions to be established by the Application Authority, which will verify compliance with the requirements. The Decree also set the mechanism for calculating the level of investment in research and development, the level of employee retention, exports, among others. It also establishes that exports of services from companies participating in this regime will not be subject to export duties. On January 13, 2021, Argentina’s Ministry of Productive Development –current Application Authority of the knowledge-based economy promotional regime- issued Resolution No. 4/2021 which was followed by Disposition N° 11/2021 issued by the Under Secretariat of Knowledge Economy on February 12, 2021. Both rules establish further details on the requirements, terms, conditions, application, and compliance procedures to be eligible under the promotional regime. MercadoLibre S.R.L. has submitted the application to be eligible to the knowledge-based economy promotional regime; such eligibility remains subject to Argentine government approval. Fair value option applied to certain financial instruments Under ASC 825, U.S. GAAP provides an option to elect fair value with impact on the statement of income as an alternative measurement for certain financial instruments and other items on the balance sheet. The Company has elected to measure certain financial assets at fair value with impact on the statement of income from January 1, 2019 for several reasons including to avoid the mismatch generated by the recognition of certain linked instruments / transactions, separately, in consolidated statement of income and consolidated statement of other comprehensive income and to better reflect the financial model applied for selected instruments. The Company’s election of the fair value option applies to the: i) Brazilian federal government bonds and ii) U.S. treasury notes. As result of the election of the fair value option, the Company recognized gains in interest income and other financial gains of $ 1,173 thousands and $ 12,004 thousands as of March 31, 2021 and 2020, respectively. Accumulated other comprehensive loss The following table sets forth the Company’s accumulated other comprehensive loss as of March 31, 2021 and December 31, 2020: March 31, December 31, 2021 2020 (In thousands) Accumulated other comprehensive loss: Foreign currency translation $ ( 508,438 ) $ ( 466,569 ) Unrealized gains (losses) on hedging activities 3,728 ( 2,469 ) Estimated tax (expense) benefit on unrealized gains (losses) ( 1,353 ) 754 $ ( 506,063 ) $ ( 468,284 ) The following tables summarize the changes in accumulated balances of other comprehensive loss for the three-months ended March 31, 2021: Unrealized Foreign Estimated tax (Losses) Gains on Currency benefit hedging activities, net Translation (expense) Total (In thousands) Balances as of December 31, 2020 $ ( 2,469 ) $ ( 466,569 ) $ 754 $ ( 468,284 ) Other comprehensive income (loss) before reclassifications 5,561 ( 41,869 ) ( 1,891 ) ( 38,199 ) Amount of (gain) loss reclassified from accumulated other comprehensive loss 636 — ( 216 ) 420 Net current period other comprehensive income (loss) 6,197 ( 41,869 ) ( 2,107 ) ( 37,779 ) Ending balance $ 3,728 $ ( 508,438 ) $ ( 1,353 ) $ ( 506,063 ) Amount of (Loss) Gain Reclassified from Details about Accumulated Accumulated Other Other Comprehensive Loss Comprehensive Affected Line Item Components Loss in the Statement of Income (In thousands) Unrealized losses on hedging activities $ ( 636 ) Cost of net revenues Estimated tax benefit on unrealized gains 216 Income tax expense Total reclassifications for the period $ ( 420 ) Total, net of income taxes Use of estimates The preparation of interim condensed consolidated financial statements in conformity with U.S. GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for, but not limited to, accounting for allowances for doubtful accounts and chargeback provisions, allowance for loans receivables, inventories valuation reserves, recoverability of goodwill, intangible assets with indefinite useful lives and deferred tax assets, impairment of short-term and long-term investments, impairment of long-lived assets, compensation costs relating to the Company’s long term retention plan, fair value of convertible debt, fair value of investments, fair value of derivative instruments, income taxes and contingencies and determination of the incremental borrowing rate at commencement date of lease operating agreements. Actual results could differ from those estimates. Recently Adopted Accounting Standards On December 18, 2019 the FASB issued the ASU 2019-12 “Income taxes (Topic 740)—Simplifying the accounting for income taxes”. The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles and also improve consistent application by clarifying and amending existing guidance, such as franchise taxes and interim recognition of enactment of tax laws or rate changes. The amendments in this update are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The adoption of this standard did not have a material impact on the Company´s financial statements. Recently issued accounting pronouncements not yet adopted On August 5, 2020 the FASB issued the ASU 2020-06 “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40)”. The amendments in this update address issues identified as a result of the complexity associated with applying generally accepted accounting principles for certain financial instruments with characteristics of liabilities and equity. For convertible instruments, accounting models for specific features are removed and amendments to the disclosure requirements are included. For contracts in an entity’s own equity, simplifies the settlement assessment by removing some requirements. Additionally, the amendments in this update affect the diluted EPS calculation for instruments that may be settled in cash or shares and for convertible instruments. The amendments in this update are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The Company is assessing the effects that the adoption of this accounting pronouncement may have on its financial statements.

Net Loss Per Share [Abstract]
Net Loss Per Share	3. Net loss per share Basic earnings per share for the Company’s common stock is computed by dividing, net loss available to common shareholders attributable to common stock for the period by the weighted average number of common shares outstanding during the period. On August 24, 2018 and August 31, 2018 the Company issued an aggregate principal amount of $ 880 million of 2.00 % Convertible Senior Notes due 2028 (see Note 11 to these interim condensed consolidated financial statements). The conversion of these notes are included in the calculation for diluted earnings per share utilizing the “if converted” method. Accordingly, conversion of these Notes is not assumed for purposes of computing diluted earnings per share if the effect is antidilutive. Additionally, on March 29, 2019 the Company issued Preferred Stock. The conversion of Preferred Stock was included in the calculation for diluted earnings per share utilizing the “if converted” method. Accordingly, conversion of the redeemable convertible preferred stock is not assumed for purposes of computing diluted earnings per share if the effect is antidilutive. The denominator for diluted net loss per share for the three-month periods ended March 31, 2021 and 2020 does not include any effect from the 2028 Notes Capped Call Transactions (as defined in Note 11) because it would be antidilutive. In the event of conversion of any or all of the 2028 Notes, the shares that would be delivered to the Company under the Capped Call Transactions (as defined in Note 11) are designed to partially neutralize the dilutive effect of the shares that the Company would issue under the Notes. S ee Note 11 to these interim condensed consolidated financial statements and Note 16 to the financial statements for the year ended December 31, 2020, contained in the Company ’s Annual Report on Form 10-K filed with the SEC for more details. For the three-month periods ended March 31, 2021 and 2020 , the effects of the conversion of the Notes and the redeemable convertible preferred stock would have been antidilutive and, as a consequence, they were not factored into the calculation of diluted earnings per share.

Segment Reporting [Abstract]
Segment Reporting	7. Segment reporting Reporting segments are based upon the Company’s internal organizational structure, the manner in which the Company’s operations are managed and resources are assigned, the criteria used by Management to evaluate the Company’s performance, the availability of separate financial information and overall materiality considerations. Segment reporting is based on geography as the main basis of segment breakdown in accordance with the criteria, as determined by Management, used to evaluate the Company’s performance. The Company’s segments include Brazil, Argentina, Mexico and other countries (which includes Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Honduras, Nicaragua, El Salvador, Bolivia, Guatemala, Panama, Paraguay, Peru, Uruguay and the United States of America). Direct contribution consists of net revenues from external customers less direct costs, which include costs of net revenues, product and technology development expenses, sales and marketing expenses and general and administrative expenses over which segment managers have direct discretionary control, such as advertising and marketing programs, customer support expenses, allowances for doubtful accounts, payroll and third-party fees.

Fair value of derivative instruments are determined considering the prevailing risk free interest rate and spot exchange rate. As of March 31, 2021 and December 31, 2020 , the Company ’s liabilities were valued at fair value using Level 2 inputs and Level 3 inputs (valuations based on unobservable inputs reflecting Company assumptions). Fair value of contingent considerations are determined based on the probability of achievement of the performance targets arising from each acquisition, as well as the Company’s historical experience with similar arrangements. Fair value of derivative instruments are determined considering the prevailing risk free interest rate and spot exchange rate. As of March 31, 2021 and December 31, 2020, the carrying value of the Company’s financial assets and liabilities measured at amortized cost approximated their fair value mainly because of their short-term maturity. These assets and liabilities included cash, cash equivalents, restricted cash and cash equivalents and short-term investments (excluding money markets funds and debt securities), accounts receivable, credit cards receivable and other means of payment, loans receivable, funds payable to customers and amounts due to merchants, other assets (excluding derivative instruments), accounts payable, salaries and social security payable (excluding variable LTRP), taxes payable, provisions and other liabilities (excluding contingent considerations and derivative instruments) . As of March 31, 2021 and December 31, 2020, the estimated fair value of the 2028 Notes (liability component), which is based on Level 2 inputs, is $ 333,759 thousands and $ 672,345 thousands, respectively, and were determined based on market interest rates. The rest of the loans payable and other financial liabilities approximate their fair value because the effective interest rates are not materially different from market interest rates. The following table summarizes the fair value level for those financial assets and liabilities of the Company measured at amortized cost as of March 31, 2021 and December 31, 2020: Balances as of Significant other Balances as of Significant other March 31, observable inputs December 31, observable inputs 2021 (Level 2) 2020 (Level 2) (In thousands) Assets Time Deposits $ 305,746 $ 305,746 $ 158,818 $ 158,818 Accounts receivable, net 64,815 64,815 49,691 49,691 Credit Cards receivable and other means of payment, net 883,670 883,670 863,073 863,073 Loans receivable, net 435,449 435,449 401,655 401,655 Other assets 263,316 263,316 236,432 236,432 Total Assets $ 1,952,996 $ 1,952,996 $ 1,709,669 $ 1,709,669 Liabilities Accounts payable and accrued expenses $ 612,206 $ 612,206 $ 767,336 $ 767,336 Funds payable to customers and amounts due to merchants 1,527,971 1,527,971 1,733,095 1,733,095 Salaries and social security payable 144,530 144,530 120,394 120,394 Taxes payable 240,167 240,167 215,918 215,918 Loans payable and other financial liabilities (*) 2,174,438 2,205,705 1,409,269 1,479,165 Other liabilities 65,463 65,463 110,139 110,139 Total Liabilities $ 4,764,775 $ 4,796,042 $ 4,356,151 $ 4,426,047 (*) The fair value of the 2028 Notes (including the equity component) is disclosed in Note 11.

Commitments And Contingencies [Abstract]
Commitments And Contingencies	9. Commitments and Contingencies Litigation and Other Legal Matters The Company is subject to certain contingent liabilities with respect to existing or potential claims, lawsuits and other proceedings. The Company accrues liabilities when it considers probable that future costs will be incurred and such costs can be reasonably estimated. Proceeding-related liabilities are based on developments to date and historical information related to actions filed against the Company. As of March 31, 2021 , the Company had accounted for estimated liabilities involving proceeding-related contingencies and other estimated contingencies of $ 8,726 thousands to cover legal actions against the Company in which its Management has assessed the likelihood of a final adverse outcome as probable. Expected legal costs related to litigations are accrued when the legal service is actually provided. In addition, as of March 31, 2021, the Company and its subsidiaries are subject to certain legal actions considered by the Company’s Management and its legal counsels to be reasonably possible for an estimated aggregate amount up to $ 55,699 thousands. No loss amounts have been accrued for such reasonably possible legal actions. Brazilian preliminary injunction against the Brazilian tax authorities On November 6, 2014, the Brazilian subsidiaries, Mercadolivre.com Atividades de Internet Ltda., Ebazar.com.br Ltda., Mercado Pago.com Representações Ltda. and the Argentine subsidiary, Mercado Libre S.R.L., filed a writ of mandamus and requested a preliminary injunction with the Federal Court of Osasco against the federal tax authority to avoid the IR (income tax) withholding over payments remitted by the Brazilian subsidiaries to MercadoLibre S.R.L. for the provision of IT support and assistance services by the latter, and requested reimbursement of the amounts improperly withheld over the course of the preceding five ( 5 ) years. The preliminary injunction was granted on the grounds that such withholding violated the convention signed between Brazil and Argentina that prevents double taxation. In August 2015, the injunction was revoked by the first instance judge in an award favorable to the federal tax authority. The Company appealed the decision and deposited with the court the disputed amounts. As of March 31, 2021 the total amount of the deposits were $ 65,563 thousands (which includes $ 5,918 thousands of interest). Such amounts are included in non-current other assets of the consolidated balance sheet. In June 2020, the Company’s appeal was dismissed. The Company submitted a new remedy before the same court in July 2020, which was dismissed on February 17, 2021. On March 18, 2021 the Company filed an appeal with the superior courts, which is now pending. Management’s opinion, based on the opinion of external legal counsel, is that the risk of losing the case is reasonably possible but not probable based on the technical merits of the Company ’s tax position and the existence of favorable decisions issued by the Federal Regional Courts. For that reason, the Company has not recorded any expense or liability for the disputed amounts. Other third parties have from time to time claimed, and others may claim in the future, that the Company was responsible for fraud committed against them, or that the Company has infringed their intellectual property rights. The underlying laws with respect to the potential liability of online intermediaries like the Company are unclear in the jurisdictions where the Company operates. Management believes that additional lawsuits alleging that the Company has violated copyright or trademark laws will be filed against the Company in the future. Intellectual property and regulatory claims, whether meritorious or not, are time consuming and costly to resolve, require significant amounts of management time, could require expensive changes in the Company’s methods of doing business, or could require the Company to enter into costly royalty or licensing agreements. The Company may be subject to patent disputes, and be subject to patent infringement claims as the Company’s services expand in scope and complexity. In particular, the Company may face additional patent infringement claims involving various aspects of the payments businesses. From time to time, the Company is involved in other disputes or regulatory inquiries that arise in the ordinary course of business. The number and significance of these disputes and inquiries are increasing as the Company’s business expands and the Company grows larger. Buyer protection program The Company provides consumers with a buyer protection program (“BPP”) for all transactions completed through the Company’s online payment solution (“Mercado Pago”). This program is designed to protect buyers in the Marketplace from losses due primarily to fraud or counterparty non-performance. The Company’s BPP provides protection to consumers by reimbursing them for the total value of a purchased item and the value of any shipping service paid if it does not arrive or does not match the seller’s description. The Company is entitled to recover from the third-party carrier companies performing the shipping service certain amounts paid under the BPP. Furthermore, in some specific circumstances (i.e. Black Friday, Hot Sale), the Company enters into insurance contracts with third-party insurance companies in order to cover contingencies that may arise from the BPP. The maximum potential exposure under this program is estimated to be the volume of payments on the Marketplace, for which claims may be made under the terms and conditions of the Company’s BPP. Based on historical losses to date, the Company does not believe that the maximum potential exposure is representative of the actual potential exposure. The Company records a liability with respect to losses under this program when they are probable and the amount can be reasonably estimated. As of March 31, 2021 and December 31, 2020, Management’s estimate of the maximum potential exposure related to the Company’s buyer protection program is $ 2,283,252 thousands and $ 2,535,041 thousands, respectively, for which the Company recorded an allowance of $ 7,384 thousands and $ 8,364 thousands , respectively. Commitments The Company entered into a purchase commitment with two U.S. suppliers in relation to the purchase of cloud platform services as follows: a) for a total amount of $ 240,500 thousands to be fully paid off between June 1, 2020 and May 31, 2024. As of March 31, 2021, the Company paid $ 62,860 thousands in relation thereto; and b) for a total amount of $ 30,000 thousands to be fully paid off between November 24, 2019 and March 23, 2023. As of March 31, 2021, the Company paid $ 7,670 thousands in relation thereto.

The 2028 Notes Capped Call Transactions are expected generally to reduce the potential dilution upon conversion of the 2028 Notes in the event that the market price of the Company’s common stock is greater than the strike price and lower than the cap price of the 2028 Notes Capped Call Transactions. The cost of the 2028 Notes Capped Call Transactions is included as a net reduction to additional paid-in capital in the stockholders’ equity section of the consolidated balance sheets. In January 2021, the Company repurchased $ 440,000 thousands principal amount of the outstanding of the 2028 Notes. The total amount paid amounted to $ 1,865,076 thousands, which includes principal, interest accrued and premium. As a result, $ 439,992 thousands of the principal amount of the 2028 Notes remains outstanding as of March 31, 2021. The settlement consideration was first allocated to the extinguishment of the liability component of the 2028 Notes repurchased. The difference of $ 29,953 thousands between the fair value of the liability component and the net carrying amount of the liability component and unamortized debt issuance costs was recognized as a loss on debt extinguishment; in addition, $ 19,294 thousands paid as a premium was recognized as a loss in Interest expense and other financial losses line in the consolidated statement of income for the three-month period ended March 31, 2021. The remaining consideration of $ 1,484,279 thousands (net of income tax effects) was allocated to the reacquisition of the equity component and recognized as a reduction of stockholders’ equity. The total estimated fair value of the 2028 Notes was $ 1,465,869 thousands and $ 3,416,819 thousands as of March 31, 2021 and December 31, 2020, respectively. The fair value was determined based on the closing trading price per $ 100 principal amount of the 2028 Notes as of the last day of trading for the period. The Company considered the fair value of the 2028 Notes as of March 31, 2021 and December 31, 2020 to be a Level 2 measurement. The fair value of the 2028 Notes is primarily affected by the trading price of the Company’s common stock and market interest rates. Based on the $ 1,472.14 closing price of the Company’s common stock on March 31, 2021 , the if-converted value of the 2028 Notes exceeded their principal amount by $ 1,020,833 thousands. The following table presents the carrying amounts of the liability and equity components related to the 2028 Notes as of March 31, 2021 and December 31, 2020 : March 31, 2021 December 31, 2020 (In thousands) Amount of the equity component (1) $ 163,653 $ 327,305 2.00 % Convertible Senior Notes due 2028 $ 439,992 $ 879,993 Unamortized debt discount (2) ( 134,257 ) ( 275,299 ) Unamortized transaction costs related to the debt component ( 4,367 ) ( 8,894 ) Contractual coupon interest accrual 44,244 41,409 Contractual coupon interest payment ( 43,120 ) ( 34,760 ) Net carrying amount $ 302,492 $ 602,449 (1) Net of $ 3,082 thousands of transaction costs related to the equity component of the 2028 Notes. (2) As of March 31, 2021 , the remaining period over which the unamortized debt discount will be amortized is 7.5 years. The following table presents the interest expense for the contractual interest, the accretion of debt discount and the amortization of debt issuance costs: Three month periods ended March 31, 2021 2020 (In thousands) Contractual coupon interest expense $ 2,836 $ 4,400 Amortization of debt discount 4,355 6,307 Amortization of debt issuance costs 102 135 Total interest expense related to the 2028 Notes $ 7,293 $ 10,842

Securitization Transactions

Securitization Transactions [Abstract]
Securitization Transactions	12. Securitization Transactions The process of securitization consists of the issuance of securities collateralized by a pool of assets through a special purpose entity, often under a VIE. The Company securitizes financial assets associated with its credit cards and loans receivable portfolio. The Company’s securitization transactions typically involve the legal transfer of financial assets to bankruptcy remote special purpose entities (“SPEs”) or the acquisition of loans receivable portfolios through SPEs. The Company generally retains economic interests in the collateralized securitization transactions, which are retained in the form of subordinated interests. For accounting purposes, the Company is precluded from recording the transfers of assets in securitization transactions as sales or is required to consolidate the SPE. The Company securitizes certain credit cards receivable related to user’s purchases through Argentine SPEs. According to the SPE contracts, the Company has determined that it has no obligation to absorb losses or the right to receive benefits of the SPE that could be significant because it does not retain any equity certificate of participation or subordinated interest in the SPEs. As the Company does not control the vehicle, its assets, liabilities, and related results are not consolidated in the Company’s financial statements. Additionally, the Company intends to securitize certain credit cards receivable related to user’s purchases through Brazilian SPE. According to the SPE contract in place, the Company has determined that it has the obligation to absorb losses or the right to receive benefits of the SPE that could be significant because it retains subordinated interest in the SPEs. As the Company controls the vehicle, the assets, liabilities, and related results are consolidated in its financial statements. The Company securitizes certain loans receivable through Brazilian, Argentine and Mexican SPEs, formed to securitize loans receivable provided by the Company to its users or purchased from financial institutions that grant loans to the Company’s users through Mercado Pago. According to the SPE contracts, the Company has determined that it has both the power to direct the activities of the entity that most significantly impact the entity’s performance and the obligation to absorb losses or the right to receive benefits of the entity that could be significant because it retains the equity certificates of participation, and would therefore also be consolidated. When the Company controls the vehicle, it accounts the securitization transactions as if they were secured financing and therefore the assets, liabilities, and related results are consolidated in its financial statements. The following table summarizes the Company’s collateralized debt as of March 31, 2021: SPEs Collateralized debt as of March 31, 2021 Interest rate Currency Maturity Mercado Crédito Merchant Fundo de Investimento em Direitos Creditórios 1,769 DI plus 3.5 % Brazilian Reais June 2021 Mercado Crédito I Brasil Fundo de Investimento Em Direitos Creditórios Não Padronizados 51,364 DI plus 2.5 % Brazilian Reais November 2023 Fundo de Investimento Em DireitosCreditórios Arandu 173,713 DI plus 1.75 % Brazilian Reais June 2023 Mercado Crédito Consumo II 5,478 Badlar rates plus 200 basis points with a min 27 % and a max 37 % Argentine Pesos July 2021 Mercado Crédito VIII 2,726 Badlar rates plus 200 basis points with a min 29 % and a max 39 % Argentine Pesos July 2021 Mercado Crédito Consumo III 6,325 Badlar rates plus 200 basis points with a min 29 % and a max 41 % Argentine Pesos August 2021 Mercado Crédito IX 9,202 Badlar rates plus 200 basis points with a min 30 % and a max 44 % Argentine Pesos February 2022 Fideicomiso de administración y fuente de pago CIB/3369 26,056 The equilibrium interbank interest rate published by Banco de Mexico in the Diario Oficial plus 3.34 % Mexican Pesos November 2022 This secured debt is issued by the SPEs and includes collateralized securities used to fund Mercado Credito business. The third-party investors in the securitization transactions have legal recourse only to the assets securing the debt and do not have recourse to the Company. Additionally, the cash flows generated by the SPEs are restricted to the payment of amounts due to third-party investors, but the Company retains the right to residual cash flows. The assets and liabilities of the SPEs are included in the Company’s interim condensed consolidated financial statements as of March 31, 2021 and December 31, 2020 as follows: March 31, December 31, 2021 2020 Assets (In thousands) Current assets: Restricted cash and cash equivalents $ 100,758 $ 249,872 Credit cards receivable and other means of payments, net 136,693 — Loans receivable, net 133,588 113,846 Total current assets 371,039 363,718 Non-current assets: Long-term investments 1,596 — Loans receivable, net 10,106 9,581 Total non-current assets 11,702 9,581 Total assets $ 382,741 $ 373,299 Liabilities Current liabilities: Accounts payable and accrued expenses $ 136 $ 100 Loans payable and other financial liabilities 25,782 25,342 Total current liabilities 25,918 25,442 Non-current liabilities: Loans payable and other financial liabilities 250,851 248,815 Total non-current liabilities 250,851 248,815 Total liabilities $ 276,769 $ 274,257

Derivative Instruments [Abstract]
Derivative Instruments	14. Derivative instruments The Company designates certain derivatives as hedges of particular risks associated with forecasted purchases. These transactions, mainly currency forward contracts, are classified as cash flow hedges. As of March 31, 2021 the Company used foreign currency exchange contracts to hedge the foreign currency effects related to the forecasted purchase of MPOS devices in U.S. dollars owed by a Brazilian subsidiary whose functional currency is the Brazilian Reais. Pursuant to these contracts, the Company will buy a notional amount of $ 10,005 thousands in April 2021, $ 10,589 thousands in May 2021, $ 10,749 thousands in June 2021, $ 8,490 thousands in July 2021, $ 8,659 thousands in August 2021, $ 8,755 thousands in September 2021, $ 4,326 thousands in October 2021, $ 7,724 thousands in November 2021, $ 5,960 thousands in December 2021, $ 2,337 thousands in January 2022, $ 2,175 thousands in February 2022 and $ 2,675 thousands in March 2022 at fixed currency rates. The Company designated the foreign currency exchange contracts as cash flow hedges, the derivative’s gain or loss is initially reported as a component of accumulated other comprehensive income and subsequently reclassified into earnings in the same period the forecasted transaction affects earnings. As of March 31, 2021, the Company estimated that the whole amount of net derivative gains related to its cash flow hedges included in accumulated other comprehensive income will be reclassified into earnings within the next 12 months. In addition, as of March 31, 2021, the Company entered into certain foreign currency exchange contracts to hedge the foreign currency fluctuations related to certain transactions denominated in U.S. dollars of a Brazilian subsidiary, whose functional currency is the Brazilian Reais, which were not designated as hedges for accounting purposes. Pursuant to these contracts, the Company will buy a notional amount of $ 60,000 thousands in April 2021, $ 52,000 thousands in May 2021, $ 39,000 thousands in June 2021, $ 30,000 thousands in July 2021 and $ 24,000 thousands in August 2021 at fixed currency rates. Finally, the Company entered into certain foreign currency exchange contracts to hedge the foreign currency fluctuations related to certain transactions denominated in U.S. dollars of a Mexican subsidiary, whose functional currency is the Mexican Peso, which were not designated as hedges for accounting purposes. Pursuant to these contracts, the Company will buy a notional amount of $ 66,470 thousands in April 2021, $ 20,349 thousands in May in 2021, $ 27,000 thousands in June 2021 and $ 15,000 thousands in July 2021, at fixed currency rates.

Equity [Abstract]
Share Repurchase Program	15. Share repurchase program On August 30, 2020, the Board of Directors of MercadoLibre authorized the Company to repurchase shares of the Company’s common stock, par value $ 0.001 per share, for aggregate consideration of up to $ 350,000 thousands. The Company expects to purchase shares at any time and from time to time, in compliance with applicable federal securities laws, through open-market purchases, block trades, derivatives, trading plans established in accordance with SEC rules, or privately negotiated transactions. The timing of repurchases will depend on factors including market conditions and prices, the Company’s liquidity requirements and alternative uses of capital. The share repurchase program expires on August 31, 2021 and may be suspended from time to time or discontinued, and there is no assurance as to the number of shares that will be repurchased under the program or that there will be any repurchases. As of March 31, 2021, the Company acquired 66,096 shares under the share repurchase program. The shares were acquired in the Argentine market and paid for in Argentine pesos at a price that reflects the additional cost of accessing US dollars through an indirect mechanism, because of restrictions imposed by the Argentine government for buying US dollars at the official exchange rate in Argentina. As a result, the Company recognized a foreign currency loss of $ 18,280 thousands for the three-month period ended March 31, 2021.

Impact Of COVID-19 Pandemic [Abstract]
Impact Of COVID-19 Pandemic	16. Impact of COVID-19 pandemic In March 2020, the outbreak of a novel strain of the coronavirus, COVID-19 was recognized as a pandemic by the World Health Organization, and the outbreak has become increasingly widespread around the world. Government-imposed total or partial lockdowns or curfews instituted throughout Latin America since March 2020, some of which have been subsequently extended, modified or rescinded, have led to a weakening of the macroeconomic environment, generating recession conditions and a devaluation of the local currencies in the countries in which the Company operates. The Company has thus far not been required to suspend its operations in any country, but the Company’s business was, and may in the future again be, negatively affected by the pandemic in terms of operations, consumer buying trends, and consequently, net revenues. Management believes that, given the uncertainty with respect to how long the pandemic will persist, what additional measures may be introduced by governments or private parties, what effect any such additional measures may have on our business or the macroeconomic impact of the pandemic in the countries where the Company operates, it is not possible to have certainty around business development and its cash generation until the outbreak of COVID-19 can be definitively contained. In terms of liquidity and cash management, relevant funding sources remain available at the geographical segment level and guaranteed senior notes were issued in January 2021 in an aggregate amount of $ 1,100,000 thousands. As of March 31, 2021, the Company’s main source of liquidity was $ 1,208,729 thousands of cash and cash equivalents and short-term investments, which excludes a $ 562,797 thousands investment related to the Central Bank of Brazil Mandatory Guarantee and a $ 71,270 thousands investment related to a guarantee for a secured line of credit in Brazil. Lastly, the revenues sources of the Company’s subsidiaries are denominated in local currency. As a result, the current weak macro-economic environment in certain countries in which the Company operates coupled with the devaluations of certain local currencies in those countries against the U.S. dollar could cause a decline in year-over-year net revenues as measured in U.S. dollars. Management has made its best estimation of the potential scenarios for 2021. However it is not possible to predict at this time with certainty the impact that COVID-19 could have and its effects, including its impact on the economies of the countries in which the Company operates, and therefore the extent of the impact on the Company’s financial condition and results of operations if conditions persist or materially deviate from those currently used in its estimates.

Summary Of Significant Accounting Policies [Abstract]
Basis of Presentation	Basis of presentation The accompanying unaudited interim condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) and include the accounts of the Company, its wholly-owned subsidiaries and consolidated Variable Interest Entities (“VIE”). These interim condensed consolidated financial statements are stated in U.S. dollars, except where otherwise indicated. Intercompany transactions and balances with subsidiaries have been eliminated for consolidation purposes. Substantially all net revenues, cost of net revenues and operating expenses are generated in the Company’s foreign operations. Long-lived assets, intangible assets and goodwill located in the foreign jurisdictions totaled $ 552,837 thousands and $ 490,464 thousands as of March 31, 2021 and December 31, 2020, respectively. These interim condensed consolidated financial statements reflect the Company’s consolidated financial position as of March 31, 2021 and December 31, 2020. These consolidated financial statements include the Company’s consolidated statements of income, comprehensive income, equity and cash flows for the three-month periods ended March 31, 2021. These interim condensed consolidated financial statements include all normal recurring adjustments that Management believes are necessary to fairly state the Company’s financial position, operating results and cash flows. From the quarter ended March 31, 2021 the Company disclosed Net product revenues as a separate line of Net revenues following its growth in significance relative to Net service revenues. As a result, the Company has reclassified the corresponding amount of the three month period ended March 31, 2020 to the line Net product revenues for an amount of $ 12,199 thousands for comparative purposes. Because all of the disclosures required by U.S. GAAP for annual consolidated financial statements are not included herein, these unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2020, contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). The Company has evaluated all subsequent events through the date these condensed consolidated financial statements were issued. The condensed consolidated statements of income, comprehensive income, equity and cash flows for the periods presented herein are not necessarily indicative of results expected for any future period. For a more detailed discussion of the Company’s significant accounting policies, see note 2 to the financial statements in the Company’s Form 10-K for the year ended December 31, 2020. During the three-month period ended March 31, 2021, there were no material updates made to the Company’s significant accounting policies.
Revenue Recognition	Revenue recognition Revenue recognition criteria for the services provided and goods sold by the Company are described in note 2 to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. Contract Balances Timing of revenue recognition may differ from the timing of invoicing to customers. Receivables represent amounts invoiced and revenue recognized prior to invoicing when the Company has satisfied the performance obligation and has the unconditional right to payment. Receivables are presented net of allowance for doubtful accounts, loans receivable and chargebacks of $ 176,912 thousands and $ 126,661 thousands as of March 31, 2021 and December 31, 2020, respectively. Deferred revenue consists of fees received related to unsatisfied performance obligations at the end of the period in accordance with ASC 606. Due to the generally short-term duration of contracts, the majority of the performance obligations are satisfied in the following reporting period. Deferred revenue as of December 31, 2020 and 2019 was $ 32,519 thousands and $ 16,590 thousands, respectively, of which $ 9,413 thousands and $ 5,562 thousands were recognized as revenue during the three-month periods ended March 31, 2021 and 2020, respectively. As of March 31, 2021, total deferred revenue was $ 18,556 thousands, mainly due to fees related to listing and optional feature services billed and loyalty programs that are expected to be recognized as revenue in the coming months.
Digital Assets	Digital Assets During the first quarter of 2021, the Company purchased an aggregate amount of $ 7,800 thousands in bitcoins. The Company accounts for its digital assets — bitcoins — as indefinite-lived intangible assets, in accordance with Accounting Standards Codification (“ASC”) 350, Intangibles—Goodwill and Other. The Company has ownership of and control over its digital assets and uses third-party custodial services to store its digital assets. The Company’s digital assets are initially recorded at cost. Subsequently, they are measured at cost, net of any impairment losses incurred since acquisition. The Company performs an analysis each quarter to identify whether events or changes in circumstances, principally decreases in the quoted prices on the active exchange, indicate that any decrease in the fair values of the digital assets below the carrying values for such assets subsequent to their acquisition will result in a recognition of impairment charges. The Company determines the fair value of its digital assets in accordance with ASC 820, Fair Value Measurement. Impairment losses are recognized in the period in which the impairment is identified. The impaired digital assets are written down to their fair value at the time of impairment and this new cost basis will not be adjusted upward for any subsequent increase in fair value. Gains (if any) are not recorded until realized upon sale. In determining the gain to be recognized upon sale, the Company calculates the difference between the sales price and carrying value of the digital assets sold immediately prior to sale.
Repurchase Of 2.00% Convertible Senior Notes Due 2028 - Extinguishment Of Debt	Repurchase of 2.00% Convertible Senior Notes due 2028 - Extinguishment of debt The derecognition of a convertible debt is based on the principle that an entity is extinguishing the liability component and reacquiring the equity component that was recognized at issuance. This approach is applied whether the debt was settled in cash, shares, other assets (or any combination), or at maturity upon conversion or upon early extinguishment. The settlement consideration is first allocated to the extinguishment of the liability component equal to the fair value of that component immediately prior to extinguishment. Any difference between that allocated amount and the net carrying amount of the liability component and unamortized debt issuance costs should be recognized as a gain or loss on debt extinguishment. Any remaining consideration is allocated to the reacquisition of the equity component and recognized as a reduction of stockholders’ equity. Any paid premium included in the repurchase price should be recognized as a loss when the debt is extinguished.
Foreign Currency Translation	Foreign currency translation All of the Company’s consolidated foreign operations use the local currency as their functional currency, except for Argentina, which has used the U.S. dollar as its functional currency since July 1, 2018. Accordingly, the foreign subsidiaries with local currency as functional currency translate assets and liabilities from their local currencies into U.S. dollars by using year-end exchange rates while income and expense accounts are translated at the average monthly rates in effect during the year, unless exchange rates fluctuate significantly during the period, in which case the exchange rates at the date of the transaction are used. The resulting translation adjustment is recorded as a component of other comprehensive loss. Argentine currency status As of July 1, 2018, the Company transitioned its Argentinian operations to highly inflationary status in accordance with U.S. GAAP, and changed the functional currency for Argentine subsidiaries from Argentine Pesos to U.S. dollars, which is the functional currency of their immediate parent company. Since the second half of 2019, the Argentine government instituted certain foreign currency exchange controls, which may restrict or partially restrict access to foreign currency, like the US dollar, to make payments abroad, either for foreign debt or the importation of goods or services, dividend payments and others, without prior authorization. Those regulations have continued to evolve, sometimes making them more or less stringent depending on the Argentine government´s perception of availability of sufficient national foreign currency reserves. The above has led to the existence of an informal foreign currency market where foreign currencies quote at levels significantly higher than the official exchange rate. However, the only exchange rate available for external commerce and financial payments is the official exchange rate, which as of March 31, 2021 was 92.0 . The Company uses Argentina’s official exchange rate to record the accounts of Argentine subsidiaries. The following table sets forth the assets, liabilities and net assets of the Company’s Argentine subsidiaries and consolidated VIEs, before intercompany eliminations, as of March 31, 2021 and December 31, 2020: March 31, December 31, 2021 2020 (In thousands) Assets $ 1,493,608 $ 1,470,885 Liabilities 1,154,563 1,230,326 Net Assets $ 339,045 $ 240,559
Income Taxes	Income taxes The Company is subject to U.S. and foreign income taxes. The Company accounts for income taxes following the liability method of accounting which requires the recognition of deferred tax liabilities and assets for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred tax assets are also recognized for tax loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets or liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company’s income tax expense consists of taxes currently payable, if any, plus the change during the period in the Company’s deferred tax assets and liabilities. A valuation allowance is recorded when, based on the available evidence, it is more likely than not that all or a portion of the Company’s deferred tax assets will not be realized. Accordingly, Management periodically assesses the need to establish a valuation allowance for deferred tax assets considering positive and negative objective evidence related to the realization of the deferred tax assets. In connection with this assessment, Management considers, among other factors, the nature, frequency and magnitude of current and cumulative losses on an individual subsidiary basis, projections of future taxable income, the duration of statutory carryforward periods, as well as feasible tax planning strategies that would be employed by the Company to prevent tax loss carryforwards from expiring unutilized. Based on Management’s assessment of available objective evidence and considering the future effect of the Company’s initiatives to capture long-term business opportunities, the Company accounted for a valuation allowance in certain subsidiaries in its Mexican operations of $ 12,176 thousands and $ 14,186 thousands for the three-month periods ended March 31, 2021 and 2020, respectively. On June 10, 2019, the Argentine government enacted Law No. 27,506 (knowledge-based economy promotional regime), which established a regime that provides certain tax benefits for companies that meet specific criteria, such as companies that derive at least 70% of their revenues from certain specified activities related to the knowledge-based economy. The regime was suspended on January 20, 2020 until new rules for the application of the knowledge-based economy promotional regime were issued. On June 25, 2020, the Chamber of Deputies passed changes to the knowledge-based economy promotional regime. The Chamber of Senates proposed further amendments, which were returned to the Chamber of Deputies and finally approved on October 7, 2020. The approved regime is effective as of January 1, 2020 until December 31, 2029. Based on the amended promotional regime, companies that meet new specified criteria shall be entitled to: i) a reduction of the income tax burden of 60% (60% for micro and small enterprises, 40% for medium-sized enterprises and 20% for large enterprises) over the promoted activities for each fiscal year, applicable to both Argentine source income and foreign source income, ii) stability of the benefits established by the knowledge-based economy promotional regime (as long as the beneficiary is registered and in good standing), iii) a non-transferable tax credit bond amounting to 70% (which can be up to 80% in certain specific cases) of the Company’s contribution to the social security regime of every employee whose job is related to the promoted activities (caps on the number of employees are applicable). Such bonds can be used within 24 months from their issue date (which period can be extended for an additional 12 months in certain cases) to offset certain federal taxes, such as value-added tax, but they cannot be used to offset income tax. On December 20, 2020, Argentina’s Executive Power issued Decree No. 1034/2020, which set the rules to implement the provisions of the knowledge-based economy promotional regime. Eligible companies must enroll in a registry according to the terms and conditions to be established by the Application Authority, which will verify compliance with the requirements. The Decree also set the mechanism for calculating the level of investment in research and development, the level of employee retention, exports, among others. It also establishes that exports of services from companies participating in this regime will not be subject to export duties. On January 13, 2021, Argentina’s Ministry of Productive Development –current Application Authority of the knowledge-based economy promotional regime- issued Resolution No. 4/2021 which was followed by Disposition N° 11/2021 issued by the Under Secretariat of Knowledge Economy on February 12, 2021. Both rules establish further details on the requirements, terms, conditions, application, and compliance procedures to be eligible under the promotional regime. MercadoLibre S.R.L. has submitted the application to be eligible to the knowledge-based economy promotional regime; such eligibility remains subject to Argentine government approval.
Fair Value Option Applied to Certain Financial Instruments	Fair value option applied to certain financial instruments Under ASC 825, U.S. GAAP provides an option to elect fair value with impact on the statement of income as an alternative measurement for certain financial instruments and other items on the balance sheet. The Company has elected to measure certain financial assets at fair value with impact on the statement of income from January 1, 2019 for several reasons including to avoid the mismatch generated by the recognition of certain linked instruments / transactions, separately, in consolidated statement of income and consolidated statement of other comprehensive income and to better reflect the financial model applied for selected instruments. The Company’s election of the fair value option applies to the: i) Brazilian federal government bonds and ii) U.S. treasury notes. As result of the election of the fair value option, the Company recognized gains in interest income and other financial gains of $ 1,173 thousands and $ 12,004 thousands as of March 31, 2021 and 2020, respectively.

Use Of Estimates	Use of estimates The preparation of interim condensed consolidated financial statements in conformity with U.S. GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for, but not limited to, accounting for allowances for doubtful accounts and chargeback provisions, allowance for loans receivables, inventories valuation reserves, recoverability of goodwill, intangible assets with indefinite useful lives and deferred tax assets, impairment of short-term and long-term investments, impairment of long-lived assets, compensation costs relating to the Company’s long term retention plan, fair value of convertible debt, fair value of investments, fair value of derivative instruments, income taxes and contingencies and determination of the incremental borrowing rate at commencement date of lease operating agreements. Actual results could differ from those estimates.
Recently Adopted Accounting Standards & Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Standards On December 18, 2019 the FASB issued the ASU 2019-12 “Income taxes (Topic 740)—Simplifying the accounting for income taxes”. The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles and also improve consistent application by clarifying and amending existing guidance, such as franchise taxes and interim recognition of enactment of tax laws or rate changes. The amendments in this update are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The adoption of this standard did not have a material impact on the Company´s financial statements. Recently issued accounting pronouncements not yet adopted On August 5, 2020 the FASB issued the ASU 2020-06 “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40)”. The amendments in this update address issues identified as a result of the complexity associated with applying generally accepted accounting principles for certain financial instruments with characteristics of liabilities and equity. For convertible instruments, accounting models for specific features are removed and amendments to the disclosure requirements are included. For contracts in an entity’s own equity, simplifies the settlement assessment by removing some requirements. Additionally, the amendments in this update affect the diluted EPS calculation for instruments that may be settled in cash or shares and for convertible instruments. The amendments in this update are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The Company is assessing the effects that the adoption of this accounting pronouncement may have on its financial statements.
