TINCheck is a comprehensive tax identification verification solution designed to help businesses validate taxpayer information, reduce compliance risks, and streamline onboarding processes. Powered by Sovos, the platform offers real-time TIN matching, bulk verification services, and API integrations that allow organizations to confirm tax ID and name combinations against IRS records and over 20 global databases. Businesses can use the platform to quickly onboard vendors, contractors, gig workers, customers, and suppliers while minimizing fraud risks and avoiding costly IRS penalties or B-Notices. TINCheck supports Know Your Customer (KYC) and Anti-Money Laundering (AML) initiatives by screening individuals and organizations against sanctions databases, watchlists, and government compliance records. The system verifies data through sources such as IRS taxpayer records, OFAC sanctions lists, Death Master File databases, USPS address validation systems, and multiple international regulatory databases. Flexible verification options allow businesses to perform instant real-time checks, upload bulk files for large-scale validation, or integrate automated verification directly into existing workflows using the TINCheck API. The platform helps organizations improve data quality and reduce administrative rework by identifying mismatches before tax filing or vendor setup processes are completed. Businesses can process large datasets efficiently and receive validation results within short turnaround times, improving operational productivity and compliance readiness. TINCheck also offers enterprise-level security features including TLS/SSL encryption, SOC 2 certified data centers, ISO 27001 compliance, and customizable user access controls.
