Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation	Basis of Presentation Interim Financial Statements The accompanying unaudited Condensed Consolidated Financial Statements have been prepared by VeriSign, Inc. (“Verisign” or the “Company”) in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, do not include all information and notes normally provided in audited financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation have been included. The results of operations for any interim period are not necessarily indicative of, nor comparable to, the results of operations for any other interim period or for a full fiscal year. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes contained in Verisign’s Annual Report on Form 10-K for the year ended December 31, 2018 (the “ 2018 Form 10-K”) filed with the SEC on February 15, 2019. Reclassifications Certain reclassifications have been made to prior period amounts to conform to current period presentation. Such reclassifications have no effect on net income as previously reported. Adoption of New Accounting Standards Effective January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases , and several related amendments, issued by the Financial Accounting Standards Board, collectively codified under Accounting Standards Codification (“ASC”) 842, Leases . ASC 842 requires most operating leases to be reported on the balance sheet as a lease liability and a right-of-use asset. This standard was applied as of the effective date of January 1, 2019, and therefore prior period amounts were not adjusted. The adoption of ASC 842 did not have a material impact on the Company’s consolidated financial statements.

Revenue Recognition [Abstract]
Revenue from Contract with Customer [Table Text Block]	Revenues The Company generates revenues in the U.S.; Europe, the Middle East and Africa (“EMEA”); China; and certain other countries, including Canada, Australia, and Japan. The following table presents our revenues disaggregated by geography, based on the billing addresses of our customers: Three Months Ended Nine Months Ended 2019 2018 2019 2018 (In thousands) U.S. $ 193,392 $ 190,980 $ 577,395 $ 563,981 EMEA 51,480 53,047 155,221 159,831 China 30,647 27,094 88,337 79,502 Other 32,902 34,656 100,165 104,203 Total revenues $ 308,421 $ 305,777 $ 921,118 $ 907,517 Revenues for the Company’s Registry Services business are attributed to the country of domicile and the respective regions in which registrars are located; however, this may differ from the regions where the registrars operate or where registrants are located. Revenues for each region may be impacted by registrars reincorporating, relocating, or from acquisitions or changes in affiliations of resellers. Revenues for each region may also be impacted by registrars domiciled in one region, registering domain names in another region. Revenues in the U.S. and EMEA regions in particular, were impacted by the decrease in revenues from the Company’s Security Services business as customers terminated or consented to the assignment of their contracts to Neustar. Deferred Revenues As payment for domain name registrations and renewals are due in advance of our performance, we record these amounts as deferred revenues. The increase in the deferred revenues balance for the nine months ended September 30, 2019 was primarily driven by amounts billed in nine months ended September 30, 2019 for domain name registrations and renewals to be recognized as revenues in future periods, offset by refunds for domain name renewals deleted during the 45-day grace period, and $ 624.9 million of revenues recognized that were included in the deferred revenues balance at the beginning of the period. The balance of deferred revenues as of September 30, 2019 represents our aggregate remaining performance obligations. Amounts included in current deferred revenues are all expected to be recognized in revenues within 12 months, except for a portion of deferred revenues that relates to domain name renewals that are deleted in the 45-day grace period following the transaction. The long-term deferred revenues amounts will be recognized in revenues over several years and in some cases up to 10 years. Historically, we have experienced a higher volume of domain name transactions, particularly renewals, in the first quarter of the year compared to other quarters. Our quarterly revenues do not reflect these seasonal patterns because the preponderance of our revenues for each quarterly period is provided by the ratable recognition of our deferred revenues balance. The effect of this seasonality has historically resulted in the largest amount of growth in our deferred revenues balance occurring during the first quarter of the year compared to the other quarters.
