TINCheck is an online tax identification number verification platform that helps businesses validate taxpayer information and support compliance workflows. It provides real-time TIN matching against IRS records, including name and TIN verification, EIN name lookup, and other U.S. taxpayer validation services. The platform can be used to verify vendors, contractors, gig workers, customers, and recipients before onboarding or tax reporting.
TINCheck supports individual checks, bulk data uploads, and API integration for automated TIN validation within vendor management, customer onboarding, KYC, and AML processes. Additional screening capabilities include checks against the Death Master File, OFAC sanctions lists, U.S. and state watchlists, global sanctions databases, GIIN records, exempt organization data, and USPS address information. Bulk Match helps identify mismatched records before filing forms such as 1099s, while dashboard controls support user access management, validation settings, two-factor authentication, and secure data processing.
