Nigeria NIN validator

Check whether a Nigerian NIN (National Identification Number) has a valid format. The NIMC-issued NIN is an 11-digit purely numeric identifier that is randomly assigned — it does not encode date of birth, state of origin or gender, and NIMC publishes no public check-digit algorithm.

The only deterministic, offline-verifiable rule is therefore the format: exactly 11 numeric digits, not all identical.

Privacy-first: everything runs in your browser with no network requests. This tool checks the format only — it cannot confirm a NIN against the NIMC database.
