Quick Start Guide

What is TINCheck?

TINCheck empowers businesses to verify that their vendors, customers, and business partners are legitimate entities. Our verifications make sure the data you have on file is accurate and compliant, with checks that cover against the IRS Name/TIN database, the Office of Foreign Assets Control (OFAC), the Death Master File, and more than 20 global governments watchlists and sanctions lists.

TINCheck allows you to verify vendors via our Real-Time TIN, Bulk TIN, or through our API.
