Question 1

What's the difference between format validation and identity verification?

Accepted Answer

Format validation checks if a NIN has valid structure (11 digits, valid checksum). It catches typos and malformed input. Identity verification (done by NIMC) confirms the NIN was officially issued and matches a real person's biometric data. Format validation is the first step; identity verification is the final confirmation.

Question 2

Can a NIN pass format validation but still be fake?

Accepted Answer

Yes. A NIN can have valid format but never have been officially issued by NIMC. Format validation catches obvious errors like typos and incorrect structure, but only NIMC can confirm if a NIN is genuinely issued and belongs to a specific person.

Question 3

Why use format validation?

Accepted Answer

Format validation catches obvious errors upfront - typos, fake numbers, and malformed input. It gives users instant feedback before they submit forms, improving data quality and user experience.

Question 4

Is it safe to enter my NIN number here?

Accepted Answer

Yes, it is safe. Our tool processes your NIN number entirely in your browser using client-side JavaScript. We do not store, transmit, or have access to the numbers you enter. No data is sent to any server.

Question 5

What does this tool actually check?

Accepted Answer

We check: (1) Length is exactly 11 digits, (2) Contains only numeric characters, (3) Verhoeff checksum is valid. This catches typos, incomplete numbers, and mathematically invalid formats.

Question 6

How can I verify a NIN for customer onboarding?

Accepted Answer

For identity verification and customer onboarding, you need NIMC's official verification services. Format validation is only the first step to filter obvious errors - it does not confirm identity.
