What is a payee number in TINS?
When a vendor first contracts with a state agency, that vendor must provide either an employer identification number (EIN) or a social security number (SSN). Each payee number has three components: a one-digit prefix number, a nine-digit base number (EIN or SSN), and a one-digit self-check number. The 11-digit payee number is ended with a three-digit number called a mail code that is unique to each mailing address or direct deposit account.
