Basis of Presentation [Abstract]
Basis of Presentation	Note 1—Basis of Presentation The accompanying unaudited consolidated financial statements of IDT Corporation and its subsidiaries (the “Company” or “IDT”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended April 30, 2016 are not necessarily indicative of the results that may be expected for the fiscal year ending July 31, 2016. The balance sheet at July 31, 2015 has been derived from the Company’s audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. For further information, please refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended July 31, 2015, as filed with the U.S. Securities and Exchange Commission (“SEC”). The Company’s fiscal year ends on July 31 of each calendar year. Each reference below to a fiscal year refers to the fiscal year ending in the calendar year indicated (e.g., fiscal 2016 refers to the fiscal year ending July 31, 2016). On June 1, 2016, the Company completed a pro rata distribution of the common stock that the Company held in the Company’s subsidiary Zedge, Inc. (“Zedge”) to the Company’s stockholders of record as of the close of business on May 26, 2016 (the “Zedge Spin-Off”). The disposition of Zedge did not meet the criteria to be reported as a discontinued operation and accordingly, its assets, liabilities, results of operations and cash flows have not been reclassified. Zedge provides a content platform that enables consumers to personalize their mobile devices with free, high quality ringtones, wallpapers, home screen app icons and notification sounds. In connection with the Zedge Spin-Off, each of the Company’s stockholders received one share of Zedge Class A common stock for every three shares of the Company’s Class A common stock, and one share of Zedge Class B common stock for every three shares of the Company’s Class B common stock, held of record as of the close of business on May 26, 2016. The Company received a legal opinion that the Zedge Spin-Off should qualify as a tax-free transaction for U.S. federal income tax purposes. In August 2015, the Company’s Board of Directors approved a plan to reorganize the Company into three separate entities by spinning off two business units to its stockholders. The three separate companies are expected to consist of (1) IDT Telecom, (2) Zedge and (3) other holdings. The reorganization and the specific components are subject to change and both internal and third party contingencies, and must receive final approval from the Company’s Board of Directors and certain third parties. The Company continues to advance the effort on the remainder of the reorganization.

In July 2015, the Company received 64,624 shares of Straight Path Communications Inc. (“Straight Path”) Class B common stock in connection with the lapsing of restrictions on awards of Straight Path restricted stock to certain of the Company’s employees and the payment of taxes related thereto. The Company spun-off Straight Path in July 2013. As part of the Straight Path spin-off, holders of the Company’s restricted Class B common stock received, in respect of those restricted shares, one share of Straight Path’s Class B common stock for every two restricted shares of the Company that they held as of the record date for the Straight Path spin-off. The Company received the Straight Path shares in exchange for the payment of an aggregate of $2.1 million for the employees’ tax withholding obligations upon the vesting event. The number of shares was determined based on their fair market value on the trading day immediately prior to the vesting date. In September and October 2015, the Company sold all of the shares for $2.6 million and recorded a gain on the sale of $0.5 million. Proceeds from maturities and sales of available-for-sale securities were $5.5 million and $4.7 million in the three months ended April 30, 2016 and 2015, respectively, and $24.2 million and $16.8 million in the nine months ended April 30, 2016 and 2015, respectively.

The Company’s investments in hedge funds are accounted for using the equity method or the cost method; therefore investments in hedge funds are not measured at fair value. Fair Value of Other Financial Instruments The estimated fair value of the Company’s other financial instruments was determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting these data to develop estimates of fair value. Consequently, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. Cash and cash equivalents, restricted cash and cash equivalents, other current assets, customer deposits, notes payable—current portion and other current liabilities. Other assets and other liabilities. The Company’s investments at April 30, 2016 and July 31, 2015 included investments in the equity of certain privately held entities and other investments that are accounted for at cost. It is not practicable to estimate the fair value of these investments because of the lack of a quoted market price for the shares of these entities, and the inability to estimate their fair value without incurring excessive cost. The carrying value of these investments was $5.4 million and $3.4 million at April 30, 2016 and July 31, 2015, respectively, which the Company believes was not impaired.

Derivative Instruments

Derivative Instruments [Abstract]
Derivative Instruments	Note 5—Derivative Instruments The primary risk managed by the Company using derivative instruments is foreign exchange risk. Foreign exchange forward contracts are entered into as hedges against unfavorable fluctuations in the U.S. Dollar – Norwegian Krone (“NOK”) exchange rate. Zedge is based in New York and Norway and much of its operations are located in Norway. The Company does not apply hedge accounting to these contracts, therefore the changes in fair value are recorded in earnings. By using derivative instruments to mitigate exposures to changes in foreign exchange rates, the Company is exposed to credit risk from the failure of the counterparty to perform under the terms of the contract. The Company minimizes the credit or repayment risk by entering into transactions with high-quality counterparties. The Company’s outstanding contracts at April 30, 2016 were as follows: Settlement Date U.S. Dollar Amount NOK Amount May 2016 1,000,000 8,238,600 July 2016 1,000,000 8,200,000 October 2016 500,000 4,087,318 The fair value of outstanding derivative instruments recorded as assets in the accompanying consolidated balance sheets were as follows: Asset Derivatives Balance Sheet Location April 30, 2016 July 31, 2015 (in thousands) Derivatives not designated or not qualifying as hedging instruments: Foreign exchange forward contracts Other current assets $ 46 $ 38 The fair value of outstanding derivative instruments recorded as liabilities in the accompanying consolidated balance sheets were as follows: Liability Derivatives Balance Sheet Location April 30, 2016 July 31, 2015 (in thousands) Derivatives not designated or not qualifying as hedging instruments: Foreign exchange forward contracts Other current liabilities $ — $ 39 The effects of derivative instruments on the consolidated statements of operations were as follows: Amount of Gain (Loss) Recognized on Derivatives Three Months Ended April 30, Nine Months Ended April 30, Derivatives not designated or not qualifying as hedging instruments Location of Gain (Loss) Recognized on Derivatives 2016 2015 2016 2015 (in thousands) Foreign exchange forward contracts Other income (expense), net $ 156 $ — $ (68 ) $ —

Stock Repurchases The Company had a stock repurchase program for the repurchase of up to an aggregate of 8.3 million shares of the Company’s Class B common stock. On January 22, 2016, the Company’s Board of Directors approved a stock repurchase program to purchase up to 8.0 million shares of the Company’s Class B common stock and cancelled the previous stock repurchase program, which had 4.6 million shares remaining available for repurchase.

In the nine months ended April 30, 2015, the Company repurchased 29,675 shares of Class B common stock for an aggregate purchase price of $0.4 million. At April 30, 2016, 8.0 million shares remained available for repurchase under the stock repurchase program. In the nine months ended April 30, 2016 and 2015, the Company paid $0.1 million and $0.3 million, respectively, to repurchase 11,250 and 16,330 shares of Class B common stock, respectively, that were tendered by employees of the Company to satisfy the employees’ tax withholding obligations in connection with the lapsing of restrictions on awards of restricted stock. Such shares are repurchased by the Company based on their fair market value on the trading day immediately prior to the vesting date. 401(k) Plan Matching Contributions The Company contributed 94,712 and 70,843 shares of its Class B common stock to the Company’s 401(k) Plan for matching contributions in the nine months ended April 30, 2016 and 2015, respectively. The Company’s cost for contributions to the 401(k) Plan was $1.4 million and $1.3 million in the nine months ended April 30, 2016 and 2015, respectively. 2015 Stock Option and Incentive Plan On December 14, 2015, the Company’s stockholders approved an amendment to the Company’s 2015 Stock Option and Incentive Plan to increase the number of shares of the Company’s Class B common stock available for the grant of awards thereunder by an additional 0.1 million shares. Stock Option Modification in connection with the Zedge Spin-Off On June 7, 2016, in connection with the Zedge Spin-Off, the Compensation Committee of the Company’s Board of Directors approved a $2.25 reduction in the exercise price of each outstanding option to purchase the Company’s Class B common stock. The Company accounted for the reduction in the exercise price of the Company’s outstanding stock options as a modification. The Company determined that there was no incremental value from the modification, therefore, the Company was not required to record a stock-based compensation charge.

Earnings Per Share [Abstract]
Earnings Per Share	Note 7—Earnings Per Share Basic earnings per share is computed by dividing net income attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock outstanding during the applicable period. Diluted earnings per share is computed in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options using the treasury stock method, unless the effect of such increase is anti-dilutive. The weighted-average number of shares used in the calculation of basic and diluted earnings per share attributable to the Company’s common stockholders consists of the following: Three Months Ended Nine Months Ended 2016 2015 2016 2015 (in thousands) Basic weighted-average number of shares 22,635 23,034 22,790 22,867 Effect of dilutive securities: Stock options — 20 — 33 Non-vested restricted Class B common stock 45 414 26 359 Diluted weighted-average number of shares 22,680 23,468 22,816 23,259 The following outstanding stock options were excluded from the calculation of diluted earnings per share because the exercise price of the stock option was greater than the average market price of the Company’s stock during the period: Three Months Ended Nine Months Ended 2016 2015 2016 2015 (in thousands) Shares excluded from the calculation of diluted earnings per share 264 15 265 166

Business Segment Information [Abstract]
Business Segment Information	Note 10—Business Segment Information The Company has two reportable business segments, Telecom Platform Services and Consumer Phone Services. Operating segments that are not reportable individually are included in All Other. The Company’s reportable segments are distinguished by types of service, customers and methods used to provide their services. The operating results of these business segments are regularly reviewed by the Company’s chief operating decision maker. The Telecom Platform Services segment provides retail telecommunications and payment offerings as well as wholesale international long distance traffic termination. The Consumer Phone Services segment provides consumer local and long distance services in certain U.S. states. Telecom Platform Services and Consumer Phone Services comprise the IDT Telecom division. Prior to the Zedge Spin-Off, All Other included Zedge, which provides a content platform that enables consumers to personalize their mobile devices with free, high quality ringtones, wallpapers, home screen app icons and notification sounds. All Other also includes the Company’s real estate holdings and other, smaller, businesses. Until the sale of Fabrix in October 2014, All Other included Fabrix, a software development company offering a cloud-based scale-out storage and computing platform optimized for big data, virtualization and media storage, processing and delivery. Corporate costs include certain services, such as compensation, consulting fees, treasury and accounts payable, tax and accounting services, human resources and payroll, corporate purchasing, corporate governance including Board of Directors’ fees, internal and external audit, investor relations, corporate insurance, corporate legal, business development, and other corporate-related general and administrative expenses including, among others, facilities costs, charitable contributions and travel, as well as depreciation expense on corporate assets. Corporate does not generate any revenues, nor does it incur any direct cost of revenues. The accounting policies of the segments are the same as the accounting policies of the Company as a whole. The Company evaluates the performance of its business segments based primarily on income (loss) from operations. IDT Telecom depreciation and amortization are allocated to Telecom Platform Services and Consumer Phone Services because the related assets are not tracked separately by segment. There are no other significant asymmetrical allocations to segments. Operating results for the business segments of the Company are as follows: (in thousands) Telecom Consumer All Other Corporate Total Three Months Ended April 30, 2016 Revenues $ 350,399 $ 1,682 $ 3,073 $ — $ 355,154 Income (loss) from operations 6,319 351 1,804 (2,798 ) 5,676 Gain on sale of interest in Fabrix Systems Ltd. — — 1,086 — 1,086 Three Months Ended April 30, 2015 Revenues $ 379,139 $ 2,098 $ 2,693 $ — $ 383,930 Income (loss) from operations 5,602 324 1,584 (5,040 ) 2,470 Gain on sale of interest in Fabrix Systems Ltd. — — 1,235 — 1,235 Nine Months Ended April 30, 2016 Revenues $ 1,112,779 $ 5,277 $ 10,130 $ — $ 1,128,186 Income (loss) from operations 22,346 980 4,079 (7,427 ) 19,978 Gain on sale of interest in Fabrix Systems Ltd. — — 1,086 — 1,086 Nine Months Ended April 30, 2015 Revenues $ 1,171,897 $ 6,652 $ 12,432 $ — $ 1,190,981 Income (loss) from operations 18,142 985 77,520 (10,834 ) 85,813 Gain on sale of interest in Fabrix Systems Ltd. — — 76,864 — 76,864

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 11—Commitments and Contingencies Legal Proceedings On May 5, 2004, the Company filed a complaint in the Supreme Court of the State of New York, County of New York, seeking injunctive relief and damages against Tyco Group, S.A.R.L., Tyco Telecommunications (US) Inc. (f/k/a TyCom (US) Inc.), Tyco International, Ltd., Tyco International (US) Inc., and TyCom Ltd. (collectively “Tyco”). The Company alleged that Tyco breached a settlement agreement that it had entered into with the Company to resolve certain disputes and civil actions among the parties. The Company alleged that Tyco did not provide the Company, as required under the settlement agreement, free of charge and for the Company’s exclusive use, a 15-year indefeasible right to use four Wavelengths in Ring Configuration (as defined in the settlement agreement) on a global undersea fiber optic network that Tyco was deploying at that time. After extensive proceedings, including several decisions and appeals, the New York Court of Appeals affirmed a lower court decision to dismiss the Company’s claim and denied the Company’s motion for re-argument of that decision. On June 23, 2015, the Company filed a new summons and complaint against Tyco in the Supreme Court of the State of New York, County of New York alleging that Tyco breached the settlement agreement. In September 2015, Tyco filed a motion to dismiss the complaint, which the Company opposed. Oral arguments were held on March 9, 2016. The parties are now awaiting a decision from the Court. In addition to the foregoing, the Company is subject to other legal proceedings that have arisen in the ordinary course of business and have not been finally adjudicated. Although there can be no assurance in this regard, the Company believes that none of the other legal proceedings to which the Company is a party will have a material adverse effect on the Company’s results of operations, cash flows or financial condition. Purchase Commitments The Company had purchase commitments of $1.9 million at April 30, 2016. Letters of Credit At April 30, 2016, the Company had letters of credit outstanding totaling $0.2 million for IDT Telecom’s business. The letters of credit outstanding at April 30, 2016 expire in the twelve month period ending April 30, 2017. Performance Bonds IDT Payment Services and IDT Telecom have performance bonds issued through third parties for the benefit of various states in order to comply with the states’ financial requirements for money remittance licenses and telecommunications resellers, respectively. At April 30, 2016, the Company had aggregate performance bonds of $13.3 million outstanding. Customer Deposits At April 30, 2016 and July 31, 2015, “Customer deposits” in the Company’s consolidated balance sheets included refundable customer deposits of $96.1 million and $84.5 million, respectively, related to IDT Financial Services Ltd., the Company’s Gibraltar-based bank. Substantially Restricted Cash and Cash Equivalents The Company treats unrestricted cash and cash equivalents held by IDT Payment Services and IDT Financial Services Ltd. as substantially restricted and unavailable for other purposes. At April 30, 2016 and July 31, 2015, “Cash and cash equivalents” in the Company’s consolidated balance sheets included an aggregate of $9.1 million and $7.5 million, respectively, held by IDT Payment Services and IDT Financial Services Ltd. that was unavailable for other purposes. Restricted Cash and Cash Equivalents Restricted cash and cash equivalents consist of the following: April 30, 2016 July 31, 2015 (in thousands) IDT Financial Services customer deposits $ 99,456 $ 87,613 Related to letters of credit 169 3,163 Other 221 259 Total restricted cash and cash equivalents $ 99,846 $ 91,035

Recently Adopted Accounting Standard and Recently Issued Accounting Standards Not Yet Adopted [Abstract]
Recently Adopted Accounting Standard and Recently Issued Accounting Standards Not Yet Adopted	Note 14—Recently Adopted Accounting Standard and Recently Issued Accounting Standards Not Yet Adopted In November 2015, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) to simplify the presentation of deferred income taxes, as well as align the presentation of deferred income tax assets and liabilities with International Financial Reporting Standards (“IFRS”). The amendments in the ASU require that deferred tax assets and liabilities be classified as noncurrent in a classified balance sheet instead of separated into current and noncurrent amounts. The Company adopted the ASU on November 1, 2015 and retrospectively applied the change. As a result, $0.8 million of deferred income tax assets that were included in current assets at July 31, 2015 were reclassified to noncurrent in the accompanying consolidated balance sheet. In May 2014, the FASB and the International Accounting Standards Board jointly issued a comprehensive new revenue recognition standard that will supersede most of the current revenue recognition guidance under U.S. GAAP and IFRS. The goals of the revenue recognition project were to clarify and converge the revenue recognition principles under U.S. GAAP and IFRS and to develop guidance that would streamline and enhance revenue recognition requirements. The Company will adopt this standard on August 1, 2018. Entities have the option of using either a full retrospective or modified retrospective approach for the adoption of the standard. The Company is evaluating the impact that the standard will have on its consolidated financial statements. In January 2016, the FASB issued an ASU to provide more information about recognition, measurement, presentation and disclosure of financial instruments. The amendments in the ASU include, among other changes, the following: (1) equity investments (except those accounted for under the equity method or that result in consolidation) will be measured at fair value with changes in fair value recognized in net income, (2) a qualitative assessment each reporting period to identify impairment of equity investments without readily determinable fair values, (3) financial assets and financial liabilities will be presented separately by measurement category and form of financial asset on the balance sheet or the notes to the financial statements, and (4) an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. Entities will no longer be able to recognize unrealized holding gains and losses on equity securities classified as available-for-sale in other comprehensive income. In addition, a practicability exception will be available for equity investments that do not have readily determinable fair values and do not qualify for the net asset value practical expedient. These investments may be measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Entities will have to reassess at each reporting period whether an investment qualifies for this practicability exception. The Company will adopt the amendments in this ASU on August 1, 2018. The Company is evaluating the impact that the ASU will have on its consolidated financial statements. In February 2016, the FASB issued an ASU related to the accounting for leases. The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The Company will adopt the new standard on August 1, 2019. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is evaluating the impact that the new standard will have on its consolidated financial statements.

IDT Financial Services Ltd. Recent Transactions [Abstract]
IDT Financial Services Ltd. Recent Transactions	Note 15—IDT Financial Services Ltd. Recent Transactions In December 2015, MasterCard Europe released a security deposit in the amount of $4.7 million made by IDT Financial Services Ltd. At July 31, 2015, this security deposit was included in “Other assets” in the accompanying consolidated balance sheet. On November 2, 2015, Visa Inc. entered into an agreement to acquire Visa Europe Limited subject to regulatory approvals. IDT Financial Services Ltd. is a member of Visa Europe and, if the transaction is consummated, will receive part of the consideration from the intended sale. On April 21, 2016, Visa Inc. announced that, in response to feedback received from the European Commission, Visa Inc. and Visa Europe reached a preliminary agreement to amend their agreement. Pursuant to the original agreement, Visa Inc. would have paid for the acquisition in two tranches. The first tranche will include cash and preferred stock convertible into Visa Inc. Class A common stock. Visa Europe estimated that IDT Financial Services Ltd. will receive, subject to adjustment, €4.7 million ($5.4 million at April 30, 2016) in cash and €1.6 million ($1.9 million at April 30, 2016) in Visa Inc. preferred stock. The second tranche was a potential earn-out, subject to certain achievements that if fulfilled, would have been paid in 2020. In the amendment to the agreement, which remains subject to the negotiation of definitive documentation of the amendment, the parties agreed to eliminate the earn-out portion of the consideration. Instead of an earn-out, the cash consideration payable will be increased by €1.75 billion ($2.0 billion at April 30, 2016), of which €750 million ($859.0 million at April 30, 2016) will be payable upon closing and €1.0 billion ($1.1 billion at April 30, 2016), plus 4% compound annual interest, will be payable on the third anniversary of closing. The transaction remains subject to regulatory approval. The closing may extend beyond the end of the second quarter of calendar 2016. The amount of consideration expected to be received is preliminary, the amounts may change, and the closing of the transaction cannot be assured. The Visa Inc. preferred stock would become fully convertible into Class A common stock of Visa Inc. twelve years after the closing. Beginning four years after closing, Visa Inc. will assess whether it is appropriate to effect a partial conversion. In addition, there will be restrictions on transferring the preferred stock until it is converted into Class A common stock. The preferred stock may only be transferred to other Visa Europe members, or to existing qualifying holders of Visa Inc.’s Class B common stock. Also, the preferred stock will not be registered under the U.S. Securities Act of 1933 and therefore is not transferable unless such transfer is registered or an exemption from registration is available.
