Methods to Validate Your NIN
- NIMC USSD: dial *346*YourNIN*NIMC# — you get a response confirming the NIN matches the name on file (subscriber fees may apply).
- NIMC mobile app: the official app validates details securely.
- In-person: visit an NIMC enrolment centre with valid ID.
What Validation Checks
It confirms the NIN exists, is active and matches your name/date of birth. A mismatch often means typos during enrolment.
If the Check Fails
- Re-check your number and name carefully.
- If unmatched, visit a NIMC enrolment centre to update records.
- Confirm corrections before using the NIN for passports or SIM linking.
Security Note
Only use official NIMC channels. A legitimate service will never ask for your full NIN plus OTP via a call or message.
