SEA Test ID Generator

QA engineers and developers across Southeast Asia constantly need format- and checksum-valid national-ID numbers as test fixtures — to seed databases, exercise validation logic, and build KYC/onboarding flows without touching real personal data. Single-country generators exist, but none unifies all five major SEA formats and lets you pin demographic fields so the generated ID is structurally correct for a chosen profile. This tool does: pick a country, optionally fix gender, birth date, and region, and it emits IDs whose check digits and encoded fields are internally consistent.

Each country is handled with its real structure. Singapore NRIC/FIN uses the weighted mod-11 check letter (with the correct S/T/F/G and the 2022 M-series rule). Indonesia's 16-digit NIK encodes the province/regency/district, a birth date where the day is offset by 40 for females, and a serial. Malaysia's MyKad encodes birth date, place-of-birth state, and a gender parity digit. Thailand's 13-digit ID carries the weighted mod-11 check digit. Vietnam's 12-digit CCCD encodes a province code plus a combined gender-and-century digit. The Validate tab runs the same logic in reverse to check and decode any ID you paste.

Everything runs locally in your browser — nothing is uploaded. Critically, these are synthetic fixtures: a checksum-valid ID is not a real, issued identity, matches no government registry, and will not pass a real identity check. Use them only for software testing and development, never to impersonate a person or defeat a KYC/verification process.
