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

string

default:"NGA"

required

ISO 3166-1 alpha-3 country code for this database service.Example: NGA

string

default:"nga_passport"

required

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

string

default:"A12345678"

required

Passport number.Example: A12345678

string

default:"Doe"

required

Family name to validate.Example: Doe

string

default:"1990-01-01"

required

Date of birth in YYYY-MM-DD format.Example: 1990-01-01

string

default:"John"

Given name to validate.Example: John

string

default:"user-1234"

Your stable user reference for this person, such as your internal user ID. Didit uses it to link standalone checks to the same end user and reduce duplicate-detection noise.Example: user-1234

Input rules & validation notes

passport_number must use uppercase letters.
passport_number must match [A-Z]\d{8}.

How to call it

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"

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 can override it.

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

{
  "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.

{
  "request_id": "req_01H…",
  "status": "In Review",
  "issuing_state": "NGA",
  "match_type": "partial_match",
  "validations": [
    {
      "outcome_code": "PARTIAL_MATCH",

        "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.

{
  "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.

{
  "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"
      }
    }
  ]
}

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
