Voter ID (EPIC Number) Format Validator

How to Use the Voter ID (EPIC) Format Validator

1. Type or paste an EPIC number into the box above.
2. Click Check. The tool verifies it against the current 10-character (3 letters + 7 digits) format used on Indian voter ID cards.
3. Read the decode table showing the series prefix and serial number split out.
4. Nothing you type is uploaded anywhere — the whole check runs as plain JavaScript in your browser tab.

What an EPIC Number Is

The Electors Photo Identity Card (EPIC) number, commonly called a "Voter ID number," is the unique identifier printed on every voter ID card issued by India's Election Commission (ECI). It's used both as a general-purpose identity document and specifically to verify your registration on the electoral roll when you vote. The modern format is a 10-character alphanumeric code: three uppercase letters followed by seven digits (for example,

The three-letter prefix generally reflects the state or issuing authority's own internal series allocation — but unlike GSTIN's state codes or a driving licence's RTO prefix, there is no single, complete, publicly published national table mapping every prefix to a specific state or constituency, since different State Election Offices have historically run their own series independently. Because of that, this tool shows the prefix as-is rather than guessing a state name.

Why There's No Checksum

The Election Commission of India has never published a checksum or self-verifying algorithm for EPIC numbers — they're issued as sequential codes within each state's series, not generated by a formula. That means, like the UAN and TAN checks in this same tool family, this validator can only confirm the shape is correct; it cannot catch a single mistyped digit the way Aadhaar's Verhoeff checksum can.

Worked Example

An Important Format Caveat

Older voter ID cards — particularly those issued before the mid-2000s in some states — used a 9-character format (3 letters + 6 digits) instead of the current 10-character standard. This tool intentionally validates only the modern 10-character format, since it's what the Election Commission issues today; a genuine older card with 9 characters will correctly show as not matching this specific pattern, which is a scope limitation, not a bug.

What This Tool Does NOT Do

This checks the modern format only. It does not query the National Voter Service Portal (NVSP) or ECINET, and it cannot confirm a number is actually issued, currently valid, or linked to a real voter's registration. For anything that actually matters — checking your name on the electoral roll, verifying your polling station, or applying for a new card — use the official voters.eci.gov.in.

Common Mistakes

• Assuming the 3-letter prefix reveals a specific state — there's no single published national mapping to rely on
• Entering an older 9-character EPIC number and expecting it to pass — this tool checks the current 10-character standard specifically
• Believing a format-valid EPIC number is proof of active voter registration — there's no checksum, and this tool doesn't query ECI systems
• Confusing your EPIC number with your Voter ID serial number on the printed electoral roll, which is a different, roll-specific number

Frequently Asked Questions

Is my EPIC number uploaded anywhere? No — everything runs locally in your browser tab.

Does this tool tell me which state issued the card? No — there's no single published national table mapping every 3-letter prefix to a state.

Does a valid format mean I'm registered to vote? No — check your actual registration status on the official voters.eci.gov.in.
