The RPACPC TAN Verification API enables businesses to verify a Tax Deduction and Collection Account Number (TAN) and retrieve the associated entity name, verification result, and TAN status returned by the source.
Integrate TAN verification into vendor onboarding, tax documentation, accounts payable, and compliance review workflows.
The TAN Verification API is part of the RPACPC Tax & Compliance Verification Suite. It accepts a TAN identifier and returns the available verification information in a structured JSON response.
The response includes the submitted TAN, associated entity name, a verification indicator, and the TAN status returned by the source.
The API response may include the following information, depending on the response received:
TAN identifier submitted for verification.
Name of the associated entity returned by the source.
Boolean indicator showing whether the result is marked as verified.
Status returned by the source, such as Active or Inactive.
Request identifiers and request/response timestamps.
Provide the TAN number along with the required request and consent fields.
RPACPC processes the request through the configured verification service.
Receive the associated entity name, verification indicator, and TAN status.
Incorporate the returned information into your internal tax verification and compliance workflows.
