Chinese ID Number Validator
Validate Chinese ID numbers (18-digit and legacy 15-digit) in bulk. Four gates: length and characters, province code, whether the birth date actually exists, and the MOD 11-2 checksum — with a specific reason instead of a generic error. Also derives birthday, sex, age and province. Everything runs locally; numbers are never uploaded.
Validation runs entirely in your browser; numbers never leave the device. Region resolves to province level only — the full administrative table has 3,000+ entries and is not worth shipping to show one county name.
