The RPACPC PAN TAN Lookup API enables businesses to look up Tax Deduction and Collection Account Number (TAN) details associated with a given Permanent Account Number (PAN).
The API returns the associated entity name, PAN number, and TAN number, helping businesses incorporate PAN-to-TAN lookups into vendor verification, tax documentation, and compliance workflows.
The PAN TAN Lookup API is part of the RPACPC Tax & Compliance Verification Suite. It accepts a PAN identifier and returns the associated entity and TAN information available through the configured verification service.
The response’s data field is an array, allowing the application to process the returned records programmatically.
The API response may include the following information, depending on the response received:
Name associated with the returned record.
PAN identifier used for the lookup.
TAN associated with the returned record.
Structured data containing the matched record or records returned by the service.
Request identifiers and request/response timestamps.
Provide the PAN number along with the required consent and request fields.
RPACPC processes the request through the configured verification service.
Receive the entity name, PAN number, and associated TAN number returned by the source.
Use the returned information in your internal tax, vendor management, or compliance workflows.
