TINCheck was founded by a team of tax professionals that understand the difficulties in complying with multiple payee compliance regulations. 

Our mission is to help companies stay on top of these regulations by providing a single platform to meet payee compliance issues.

TINCheck allows you to verify TIN, SSN, EIN, OFAC, DMF, addresses, and much more from a single platform that covers all your list-checking needs. The TINCheck platform operates in real-time, ensuring you will always be provided with the most up-to-date results.

We also offer bulk file TIN/Name matching services for users that don’t need real-time results. Additionally, we offer all of our validations as web services that allow you to integrate these routines into your current AP systems and workflows, along with two-factor authentication options for additional security.
