What is a valid PAN format?

PAN follows AAAAA9999A (five letters, four digits, one letter). This tool validates format only; it does not verify issuance or authenticity.

What does the 4th and 5th letter mean?

The 4th letter denotes the PAN category (e.g., P=Individual, C=Company). For individuals, the 5th letter should match the surname's first letter.

How do you validate a GSTIN?

We check the standard 15-character format and compute the checksum using the documented base-36 method. We also cross-check that the PAN embedded in the GSTIN matches the PAN you entered.

No. All validation happens locally in your browser. Nothing is uploaded.
