PAN Card Format Decoded: What Each of the 10 Characters Means

PAN (Permanent Account Number) is India's primary tax identifier — required for every salary, every property purchase over ₹10 lakh, every share trade, every bank transaction over ₹50,000. The format is more structured than most users realise. A quick read tells you whether the PAN belongs to an individual, a partnership firm, a HUF, or a company — without ever calling the income tax portal.

The 10-character structure

Take an example PAN: ABCPK1234L.

• Characters 1-3: alphabetic series. Officially “random” but in practice tied to the issuing AO (Assessing Officer) range. No personal information here.
• Character 4: entity type — the most informative single character on a PAN.
• Character 5: first letter of the holder's surname (for individuals) or first letter of the entity name (for non-individuals).
• Characters 6-9: sequential 4-digit number, allocated by the IT department.
• Character 10: alphabetic check character, computed from the previous 9.

The entity type at character 4

The 4th character is the most useful single piece of information on a PAN. It tells you what kind of entity holds it:

Use our PAN Format Checker to validate format and decode the entity type from any PAN.

Surname rule at character 5

For individuals (entity = P): the 5th character is the first letter of the surname, not first name. Sneha Patel's PAN starts with ...PP...; Rahul Mehta's starts with ...PM.... This is sometimes useful as a sanity check — a PAN claiming to be for “Sneha Patel” with 5th character “K” is suspicious.

For non-individuals: 5th character is the first letter of the registered entity name. Tata Consultancy Services Ltd → first letter T → 5th character T.

The check character (character 10)

The last alphabetic character is computed via the Mod 36algorithm applied to the first 9 characters. It exists to catch typos. If even one character is mistyped, the check letter won't match.

This is what offline PAN validators (like ours) actually verify. A “valid PAN format” means: 10 chars, correct character types per position, AND the check character matches what the algorithm computes from the first 9.

What format check can and can't tell you

• Can tell: is this a structurally valid PAN? (5 letters + 4 digits + 1 letter, with correct check character)
• Can tell: what entity type is this PAN issued to? (from 4th character)
• Can tell: probable surname initial of the holder? (from 5th character, individuals only)
• Can't tell: is this PAN active / suspended / cancelled? (requires income tax portal lookup)
• Can't tell: who owns this PAN? (NSDL/protean only show name on submitted PAN+name pairs, not name from PAN alone)
• Can't tell: is this PAN linked to Aadhaar? (requires income tax portal lookup)

Verifying a third party's PAN

For business KYC — onboarding a new vendor or customer — combine format check with portal verification:

1. Run PAN through PAN Format Checker to verify structure.
2. Cross-check name match on income tax portal's PAN verification (free) or via paid APIs (Karza, Cashfree, Razorpay) for batch verification.
3. For high-value transactions or high-risk vendors, also verify GSTIN and bank account separately.

PAN vs Aadhaar vs GSTIN

• PAN: 10 characters, tax identifier, used for all financial transactions and ITR filing.
• Aadhaar: 12 digits, identity / residence proof, increasingly required alongside PAN.
• GSTIN: 15 characters, business tax registration, includes the embedded PAN of the business. Use our GSTIN Format Checker to decode.

Frequently asked

Why is my PAN's 4th character not what I expect?Verify whether you're looking at an individual or HUF PAN. If you applied as a HUF, your 4th character is H, not P. If you applied as a sole proprietor (which India treats as “individual”), it's P.

Can I have multiple PANs? No. Holding multiple PANs is an offence under Section 272B of the Income Tax Act, ₹10,000 penalty per duplicate. If you have duplicates (often from old NSDL paper applications), surrender the duplicates immediately via Form 49A correction.

What does PAN stand for?Permanent Account Number — the “permanent” bit means it doesn't change with address, employer, or marital status. Once issued, it's yours for life.
