Texas Identification Number System (TINS)

The Texas Identification Number System (TINS) is an in-house system implemented in 1989 that provides vendor/payee information to other critical statewide systems. Associated subsystems include warrant printing, ACH processing, held payments and payment inquiries.

TINS captures information on individuals or entities that have received or may receive payments from the state of Texas, including state employees, vendors and individual recipients. TINS maintains information such as the payee’s identifying information as well as the address and direct deposit account information that agencies use to remit payments.

TINS also captures information on individuals or entities that are indebted to the state and facilitates the withholding of payments until their obligations to the state are met. TINS retains historical information to support inquiries on payments issued to specific entities over a period of time.
