How to Use

  1. 1 Type or paste the 10-character PAN
  2. 2 Case, spaces, and dashes are cleaned automatically
  3. 3 See instantly whether the format is valid
  4. 4 Read the decoded entity type from the 4th character
  5. 5 Review the letters / digits / check segment breakdown

Features

  • Instant format validation as you type
  • Decodes the 4th-character entity type (Individual, Company, HUF, Firm…)
  • Shows the name-initial 5th character
  • Clear, specific error messages for invalid input
  • Per-segment breakdown of the PAN structure
  • 100% in-browser — nothing you type is uploaded

Why it Matters

A mistyped PAN gets tax returns, KYC forms, and bank applications rejected. Catching a format error in seconds — and knowing what the entity-type character should be — saves a rejected submission and a re-do. It is the fastest sanity check before you file anything.

What this tool does

The PAN Validator checks whether an Indian Permanent Account Number matches the official 10-character AAAAA0000A pattern, decodes the 4th-character entity type, and shows the structure broken into its letter, digit, and check segments — instantly, as you type.

How it works

The tool cleans your input (removing spaces and dashes and upper-casing it), then tests it against the canonical PAN regular expression: five letters, four digits, one letter. It reads the 4th character to identify the holder type and the 5th character as the name initial. Everything runs locally.

Format check only — not a government lookup

PAN has no public checksum, so format validity cannot prove a PAN is real, active, or registered to a particular person. This tool is a fast first-pass format screen — not verification. Confirming a PAN against the Income Tax Department / NSDL-Protean database requires a licensed verification API (a proposed Pro feature).

Privacy

Everything runs in your browser. The PAN you enter is never uploaded, logged, or stored.

Frequently Asked Questions

What is the format of a PAN?
A PAN is exactly 10 characters: five uppercase letters, then four digits, then one uppercase letter (AAAAA0000A). The 4th letter is the entity type and the 5th is the first letter of your surname or entity name.
Does this verify that the PAN is real?
No. This tool checks the format and decodes the structure only. PAN has no public checksum, so a format-valid PAN is not necessarily a real or active one. Only the Income Tax Department / NSDL-Protean database can confirm that — a paid feature on our proposed Pro tier.
What does the 4th character mean?
It identifies the holder type: P = Individual, C = Company, H = HUF, F = Firm/LLP, A = AOP, T = Trust, B = Body of Individuals, L = Local Authority, J = Artificial Juridical Person, G = Government. The tool decodes it for you.
Is my PAN stored anywhere?
No. The check runs entirely in your browser. The PAN you enter is never uploaded, logged, or stored.
Why was my valid-looking PAN marked invalid?
Common causes are the wrong length, a digit where a letter should be (or vice versa), or an unrecognised 4th character. The tool lists the exact reason so you can fix it.
