Does the NIN encode date of birth or state of origin?

No. The Nigerian NIN is a randomly assigned 11-digit number and does not encode date of birth, state of origin or gender. NIMC also publishes no public check-digit algorithm, so only the 11-digit numeric format can be verified offline.

Can this tool confirm a NIN is real or linked to a person?

No. It checks the structural format only (exactly 11 numeric digits, not all identical). It cannot query the NIMC database or confirm that a NIN is live or belongs to anyone — that requires official NIMC verification.

Is my NIN sent anywhere?

No. The validator is privacy-first. All processing happens locally in your browser with no network requests — your NIN never leaves your device.

Nigeria NIN Validator — Check Your 11-Digit NIN Format

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.
