PAN to GST Verification API simplifies the process of acquiring a GST number for your business by conducting a GST search using your PAN. When you input your PAN number, the API provides the corresponding GST number, along with its active and inactive status. Ensuring the accurate link between PAN and GST is essential for secure and fraud-free transactions for both merchants and users. Utilizing the RPACPC PAN and GST Linkage API, you can effortlessly discover, validate, and retrieve all GST numbers associated with a specific PAN number.

Incorrect, inactive, or mismatched PAN and GST details can delay customer onboarding, trigger verification failures, and create tax compliance issues. Verifying the PAN-to-GST relationship at the point of capture helps improve data accuracy, reduce manual checks, and identify inconsistencies early.
Fraudsters may submit forged, incorrect, or inactive PAN numbers, increasing identity fraud risks and causing KYC verification failures.
Manually validating PAN details slows customer onboarding, increases operational costs, and introduces avoidable human errors.
Mistyped or mismatched PAN details lead to duplicate records, failed compliance checks, and poor customer experiences across financial workflows.
