Step-by-Step Troubleshooting
Verify NIN Format
Ensure your NIN has exactly 11 digits with no spaces, letters, or special characters.
Check Each Digit
Compare your entry with your official NIN slip, paying special attention to similar-looking digits (0/O, 1/I, 6/G, 8/B).
Use Multiple Sources
If available, cross-reference your NIN from multiple documents (voter's card, driver's license, passport).
Try Different Times
If experiencing system errors, try validation during different times of the day when server load might be lower.
Contact NIMC
If problems persist, contact NIMC directly at 0700-CALL-NIMC or visit your nearest enrollment center.
