Founded in 2005, TINCheck, LLC is a technology company specializing in identity and tax compliance verification services. Its primary offering is a real-time service that matches Taxpayer Identification Numbers (TIN) with names against IRS records, helping businesses validate vendor and payee information for accurate 1099 reporting and avoiding B-Notices. The service also includes checks against the U.S. Treasury's Office of Foreign Assets Control (OFAC) Specially Designated Nationals (SDN) list to ensure compliance with anti-terrorism financing regulations.
