What is TINCheck?
TINCheck is a cloud-based tax identity verification service by Sovos that helps businesses validate taxpayer identification numbers (TINs), employer identification numbers (EINs), and name combinations against the IRS database and 30+ government watchlists – all in a single check. The platform is designed for organizations that need to reduce the risk of IRS penalties, B-notices, and sanctions exposure during vendor onboarding, customer verification, and 1099 filing season.
Unlike the free IRS TIN matching program, which limits users to 25 interactive lookups per session and returns results overnight for bulk requests, TINCheck delivers real-time verification results in seconds. Each check simultaneously screens against the IRS Name/TIN database, the Social Security Administration’s Death Master File (DMF), OFAC sanctions lists including SDN and consolidated sanctions, and over 20 additional global watchlists covering EU sanctions, Interpol, FBI wanted lists, and more.
TINCheck offers three access methods to fit different workflows. Real-time checks through the web interface handle individual lookups during onboarding. Bulk matching accepts file uploads of large datasets and returns results within 48 hours – ideal for pre-filing 1099 data cleansing. The REST and SOAP API embeds verification directly into CRM, ERP, and accounts payable systems for automated compliance at scale. Plans start at $19.95 per month for 25 verifications, with volume discounts available for organizations processing thousands of checks annually.
Sovos, the parent company behind TINCheck, is a global tax compliance provider founded in 1979 that serves over 100,000 customers across 100+ countries. TINCheck is trusted by financial institutions, insurance companies, higher education institutions, retail and ecommerce platforms, and government contractors for identity verification and regulatory compliance.
