# NIN Verification API (Enhanced)

> PayVessel enhanced NIN verification API returns extended NIN profile data for Nigerian identity verification.

Enhanced NIN verification gives you a richer NIN-linked identity profile from a single NIN input.

## Best For

* Higher-trust customer onboarding
* Identity enrichment
* Compliance review and deeper KYC checks

## What You Submit

You submit the customer’s NIN.

## What You Get Back

The response can include:

* First name, middle name, and surname
* Gender
* Birth date
* Photo
* Telephone number

## How To Use It

Use enhanced NIN when you need to retrieve identity data first and compare it to your own records second.

Typical pattern:

1. Retrieve the NIN profile.
2. Compare returned values to the customer profile in your system.
3. Add document or bank-account verification where required.
4. Log the verification outcome for audit and support.
