# Validate BVN

> Match a name and date of birth against a BVN record and get per-field confidence scores.

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

Confirm that a name and date of birth match a BVN — without pulling the full record. Returns a per-field match status and confidence score.

## 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                                   |
| ------------ | ------ | -------- | --------------------------------------------- |
| `bvn`        | string | Yes      | A valid BVN number.                           |
| `first_name` | string | No       | First name to match against the record.       |
| `last_name`  | string | No       | Last name to match against the record.        |
| `dob`        | string | No       | Date of birth to match, in yyyy-mm-dd format. |

## Response

Each supplied field comes back with a `status` (matched or not) and, for names, a `confidence_value` from 0–100. Use this when you only need to verify identity, not retrieve it.

## When the BVN isn’t found

An unknown BVN returns `400` with an error message:

```json 400 — Bad Request theme={null}
{
  "error": "BVN not found"
}
```

## Errors

| Code  | Meaning                                                                                       |
| ----- | --------------------------------------------------------------------------------------------- |
| `400` | Bad request — a required parameter is missing or malformed.                                   |
| `401` | Unauthorized — check your key and `AppId` (no `Bearer` prefix).                               |
| `402` | Insufficient wallet balance. [Fund your wallet](/api-reference/core-concepts/wallet-billing). |
| `404` | No record found for the supplied identifier.                                                  |
| `424` | The upstream source was unavailable — retry shortly.                                          |
| `429` | Too many requests — back off and retry.                                                       |
