TIN Verification API
Verify a Taxpayer Identification Number and retrieve dealer registration details, CST status and address information, for vendor and dealer checks.
What the TIN Verification API does
TIN Verification checks a Taxpayer Identification Number and returns the dealer's registration details, CST status, address and related registration information.
TIN belongs to the pre-GST VAT regime, and it still appears in older records and legacy contracts. Being able to verify it matters when you are reconciling historical documentation rather than onboarding fresh.
