Verifies that a Zambian National Registration Card (NRC) number belongs to the named taxpayer in the Zambia Revenue Authority register. The register holds the taxpayer’s full name only, so the name is the one field compared. 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:"ZMB"

required

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

string

default:"zmb_national_id"

required

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

string

default:"123456/78/9"

required

National identity number for this service.Example: 123456/78/9

string

default:"John"

required

Given name to validate.Example: John

string

default:"Doe"

required

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

national_id must use uppercase letters.
national_id must match \d{6}/?\d{2}/?\d.

How to call it

curl -X POST "https://verification.didit.me/v3/database-validation/" \
  -H "x-api-key: YOUR_API_KEY" \
  -F "issuing_state=ZMB" \
  -F "services=zmb_national_id" \
  -F "vendor_data=user-1234" \
  -F "national_id=123456/78/9" \
  -F "first_name=John" \
  -F "last_name=Doe"

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": "ZMB",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "zmb_national_id",
      "service_name": "Zambia NRC (tax register)",
      "source_data": {
        "first_name": "John",
        "full_name": "John Doe",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe",
        "registration_status": "sample_value"
      },
      "validation": {
        "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": "ZMB",
  "match_type": "partial_match",
  "validations": [
    {
      "outcome_code": "PARTIAL_MATCH",
      "service_id": "zmb_national_id",
      "service_name": "Zambia NRC (tax register)",
      "source_data": {
        "first_name": "John",
        "full_name": "John Doe",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe",
        "registration_status": "sample_value"
      },
      "validation": {
        "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": "ZMB",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "zmb_national_id",
      "service_name": "Zambia NRC (tax register)",
      "source_data": {
        "full_name": "NO_MATCH",
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "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": "ZMB",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "DOCUMENT_NOT_FOUND",
      "service_id": "zmb_national_id",
      "service_name": "Zambia NRC (tax register)",
      "source_data": {
        "full_name": "NO_MATCH",
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "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 zmb_national_id currently documents this normalized shape:

first_name
full_name
identification_number
last_name
registration_status

Pricing & SLAs

Zambia NRC (tax register) 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.
