Verifies Peruvian DNI against the RENIEC civil registry. 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:"PER"

required

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

string

default:"per_dni"

required

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

string

default:"11111111"

required

Country-specific personal identity number.Example: 11111111

string

default:"John"

Given name to validate.Example: John

string

default:"Doe"

Family name to validate.Example: Doe

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

Peruvian DNI (exactly 8 digits)
personal_number must contain digits only; remove spaces, hyphens, and punctuation before sending the request.
personal_number must be exactly 8 characters long.

How to call it

curl -X POST "https://verification.didit.me/v3/database-validation/" \
  -H "x-api-key: YOUR_API_KEY" \
  -F "issuing_state=PER" \
  -F "services=per_dni" \
  -F "vendor_data=user-1234" \
  -F "personal_number=11111111"

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": "PER",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "per_dni",
      "service_name": "Peru - DNI verification",
      "source_data": {
        "first_name": "John",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe",
        "maternal_name": "Doe Maternal",
        "paternal_name": "Doe Paternal",
        "verification_letter": "G",
        "verification_number": 2
      },
      "validation": {
        "identification_number": "full_match"
      }
    }
  ]
}

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

{
  "request_id": "req_01H…",
  "status": "Declined",
  "issuing_state": "PER",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "per_dni",
      "service_name": "Peru - DNI verification",
      "source_data": {
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "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": "PER",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "DOCUMENT_NOT_FOUND",
      "service_id": "per_dni",
      "service_name": "Peru - DNI verification",
      "source_data": {
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "identification_number": "no_match"
      }
    }
  ]
}

Returned data

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

first_name
identification_number
last_name
maternal_name
paternal_name
verification_letter
verification_number
