TAN Validator
Validate the structure of a Tax Deduction and Collection Account Number — the four letters, five digits and one letter that anyone deducting TDS must quote. Decodes the jurisdiction (city) code and the deductor's name initial. Format only, not a live check.
A TAN is issued to anyone who has to deduct or collect tax at source (TDS/TCS). This checks the structure only — there is no public check-digit, so the last letter isn't verified, and only the Income Tax Department can confirm a TAN is active. Verify one on the TRACES portal or the “Know your TAN” service. Nothing is uploaded.
FAQ
- Does this confirm the TAN is registered?
- No — only the Income Tax Department can. Use the 'Know Your TAN' service on the income-tax portal or the TRACES site to confirm one is active.
- What do the parts of a TAN mean?
- The first three letters are the jurisdiction (usually the city where it was issued), the fourth letter is the first letter of the deductor's name, then a 5-digit number and a final letter. There is no public check digit.
