Voter ID (EPIC)

Name: indycheck
Author: dusmamud

Validates a Voter ID number — the EPIC (Electors Photo Identity Card) number issued by the Election Commission of India. Cards in the current series carry 10 characters: a 3-letter series (a Functional Unique Serial Number, different for every assembly constituency) followed by 7 digits.

Rules

Rule	Detail
Format	`^[A-Z]{3}[0-9]{7}$`
Length	Exactly 10 characters
Checksum	None — format only, no public checksum
Legacy cards	Older cards used different formats, including ones with slashes (e.g. `XX/01/001/000123`). Those are not accepted — this validator covers the current series only

Usage

import { validateEpic } from 'indycheck';

validateEpic('ABC1234567');
// { ok: true, code: 'VALID', normalized: 'ABC1234567',
//   parsed: { epic: 'ABC1234567' } }

from indycheck import validate_epic

validate_epic("ABC1234567").ok  # True

use indycheck::validate_epic;

let r = validate_epic("ABC1234567");
assert!(r.ok);

Examples

Input	Result	Code
`ABC1234567`	Valid	`VALID`
`XYZ7654321`	Valid	`VALID`

`AB1234567`	Invalid — 9 characters	`INVALID_LENGTH`
`ABC123456`	Invalid — 9 characters	`INVALID_LENGTH`
`ABC123456A`	Invalid — letter at the end	`INVALID_FORMAT`
`ABC/01/001/000123`	Invalid — legacy format, not accepted	`INVALID_LENGTH`
(empty)	Invalid	`EMPTY`

Error codes

Code	Means
`EMPTY`	Nothing was passed in
`INVALID_LENGTH`	Not exactly 10 characters
`INVALID_FORMAT`	Doesn’t match 3 letters + 7 digits, or is a legacy format
