Verifies a Nigerian international passport against the Nigeria Immigration Service register. The register only answers when the passport number, surname and date of birth belong together. Didit exposes this service through `POST /v3/database-validation/` so you can verify the submitted data against the authoritative source and receive normalized match results.

## Body parameters

<ParamField body="issuing_state" type="string" required default="NGA" placeholder="NGA">
  ISO 3166-1 alpha-3 country code for this database service.

  Example: `NGA`

  Array containing this service ID. Pinning the service keeps the request scoped to this exact database.

  Example: `nga_passport`
</ParamField>

<ParamField body="passport_number" type="string" required default="A12345678" placeholder="A12345678">
  Passport number.

  Family name to validate.

  Example: `Doe`
</ParamField>

<ParamField body="date_of_birth" type="string" required default="1990-01-01" placeholder="1990-01-01">

## How to call it

<RequestExample>
  ```bash cURL theme={null}
  curl -X POST "https://verification.didit.me/v3/database-validation/" \
    -H "x-api-key: YOUR_API_KEY" \
    -F "issuing_state=NGA" \
    -F "services=nga_passport" \
    -F "vendor_data=user-1234" \
    -F "passport_number=A12345678" \
    -F "last_name=Doe" \
    -F "date_of_birth=1990-01-01"
  ```
</RequestExample>

<ResponseExample>
  Every successful call returns HTTP `200`. The **`outcome_code`** field tells you what actually happened — distinguishing, for example, a real biometric mismatch (`BIOMETRIC_NO_MATCH`) from a selfie that could not be read (`BIOMETRIC_IMAGE_UNUSABLE`). The `status` shown is the default feature status; your configured [Partial Match / No Match actions](/core-technology/database-validation/database-validation-warnings) can override it.

  **`MATCH`** — The registry confirmed the identity and every checked field matched.

  ```json 200 OK — MATCH theme={null}
  {
    "request_id": "req_01H…",
    "status": "Approved",
    "issuing_state": "NGA",
    "match_type": "full_match",
    "validations": [
      {
        "outcome_code": "MATCH",
        "service_id": "nga_passport",
        "service_name": "Nigeria International Passport (NIS)",
        "source_data": {
          "date_of_birth": "1990-01-01",
          "first_name": "John",
          "identification_number": "SAMPLE-ID-12345",
          "last_name": "Doe"
        },
        "validation": {
          "date_of_birth": "full_match",
          "full_name": "full_match",
          "identification_number": "full_match"
        }
      }
    ]
  }
  ```

  **`PARTIAL_MATCH`** — The identification number was found but one or more personal fields (usually name or date of birth) did not fully match.

  ```json 200 OK — PARTIAL_MATCH theme={null}
  {
    "request_id": "req_01H…",
    "status": "In Review",
    "issuing_state": "NGA",
    "match_type": "partial_match",
    "validations": [
      {
        "outcome_code": "PARTIAL_MATCH",
        "service_id": "nga_passport",
        "service_name": "Nigeria International Passport (NIS)",
        "source_data": {
          "date_of_birth": "1990-01-01",
          "first_name": "John",
          "identification_number": "SAMPLE-ID-12345",
          "last_name": "Doe"
        },
        "validation": {
          "date_of_birth": "full_match",
          "full_name": "no_match",
          "identification_number": "full_match"
        }
      }
    ]
  }
  ```

  **`NO_MATCH`** — The registry returned no match for the submitted data.

  ```json 200 OK — NO_MATCH theme={null}
  {
    "request_id": "req_01H…",
    "status": "Declined",
    "issuing_state": "NGA",
    "match_type": "no_match",
    "validations": [
      {
        "outcome_code": "NO_MATCH",
        "service_id": "nga_passport",
        "service_name": "Nigeria International Passport (NIS)",
        "source_data": {
          "date_of_birth": "NO_MATCH",
          "full_name": "NO_MATCH",
          "identification_number": "NO_MATCH"
        },
        "validation": {
          "date_of_birth": "no_match",
          "full_name": "no_match",
          "identification_number": "no_match"
        }
      }
    ]
  }
  ```

  **`DOCUMENT_NOT_FOUND`** — The submitted document number does not correspond to any record in the registry.

  ```json 200 OK — DOCUMENT_NOT_FOUND theme={null}
  {
    "request_id": "req_01H…",
    "status": "Declined",
    "issuing_state": "NGA",
    "match_type": "no_match",
    "validations": [
      {
        "outcome_code": "DOCUMENT_NOT_FOUND",
        "service_id": "nga_passport",
        "service_name": "Nigeria International Passport (NIS)",
        "source_data": {
          "date_of_birth": "NO_MATCH",
          "full_name": "NO_MATCH",
          "identification_number": "NO_MATCH"
        },
        "validation": {
          "date_of_birth": "no_match",
          "full_name": "no_match",
          "identification_number": "no_match"
        }
      }
    ]
  }
  ```
</ResponseExample>

## Returned data

The exact fields surfaced in `source_data` depend on what the registry returns. The generated example for `nga_passport` currently documents this normalized shape:

* `date_of_birth`
* `first_name`
* `identification_number`
* `last_name`

## Pricing & SLAs

Nigeria International Passport (NIS) queries are billed only when Didit receives a conclusive result from the validation source.

* **Per-call price:** \$0.20 USD.
* **Billing:** per successful query. You are not charged when the registry is unreachable, when required fields are missing, or when the request is rejected before reaching the source.
* **Latency:** typical p95 \< 2 s.
* **Availability:** 99.9% per quarter on Didit's side; downstream source availability varies by country and dataset.
