PAN, GSTIN and IFSC format validator

How to use this calculator

1. Enter the number you want to check in the fields provided.
2. Choose the type of number to match your situation.
3. Read whether the format and the checksum are valid in the result.

A valid format does not mean that the number is issued or active; verify it on the official portal.

The result is an estimate for the figures you enter. It is not a filed return, a certificate or professional advice. Rates, thresholds and section numbers change with each Finance Act, and the Income-tax Act, 2025 applies from 1 April 2026 with new section and form numbers.
