# Lookup NIN

> Look up a Nigerian National Identity Number (NIN) and return the holder's identity record.

<div className="dj-endpoint">
  <span className={`dj-method dj-method-get`}>GET</span>
  <code>/api/v1/kyc/nin</code>
</div>

Retrieve the identity record tied to a Nigerian National Identity Number (NIN) from NIMC.

## Headers

| Header          | Required | Description                                         |
| --------------- | -------- | --------------------------------------------------- |
| `Authorization` | Yes      | Your app's secret key, sent as-is — *not* `Bearer`. |
| `AppId`         | Yes      | The App ID from your dashboard.                     |

## Query parameters

| Parameter | Type   | Required | Description                                |
| --------- | ------ | -------- | ------------------------------------------ |
| `nin`     | string | Yes      | A valid 11-digit National Identity Number. |

## Response

Returns an `entity` with the holder’s name, gender, date of birth, phone number, and a base64-encoded `photo`.

## Other NIN lookups

Two variants return more than the basic record — each documented on its own page:

* [Advanced NIN](/api-reference/individual-verification/nigeria/advanced-nin) — the identity data plus extra fields like `tax_id` and `tax_residency`.
* [NIN Slip](/api-reference/individual-verification/nigeria/nin-slip) — the person’s NIN slip data (`GET /api/v1/kyc/nin/nin_slip`).
