# Country Codes

> ISO 3166-1 alpha-2 country codes used across all Zenoo API country, nationality, and jurisdiction fields.

# Country Codes

Zenoo uses ISO 3166-1 alpha-2 country codes for all country fields: `country`, `nationality`, `jurisdiction`, and address-related fields.

## Format

Always pass a two-letter uppercase code.

```json theme={null}
{
  "country": "GB",
  "nationality": "IE"
}
```

## Common mistakes

<Warning>
  These are the most frequent country code errors. The API will return a `400 VALIDATION_ERROR` for any invalid code.

  | Incorrect | Correct | Reason                                         |
  | --------- | ------- | ---------------------------------------------- |
  | `UK`      | `GB`    | ISO standard uses `GB` for the United Kingdom  |
  | `USA`     | `US`    | Must be exactly 2 characters                   |
  | `BVI`     | `VG`    | British Virgin Islands uses `VG` in ISO 3166-1 |
  | `UAE`     | `AE`    | United Arab Emirates uses `AE`                 |
  | `EN`      | `GB`    | `EN` is a language code, not a country code    |
  | `gb`      | `GB`    | Must be uppercase                              |
</Warning>

Submitting an invalid country code returns a `400 VALIDATION_ERROR`:

```json theme={null}
{
  "error": "VALIDATION_ERROR",
  "message": "Invalid country code: UK. Use ISO 3166-1 alpha-2 (GB).",
  "request_id": "req-a1b2c3d4"
}
```

## Supported jurisdictions

Zenoo supports 200+ jurisdictions for screening. Company registry verification coverage varies by jurisdiction.

For a full list of supported jurisdictions and registry coverage, contact your Zenoo account manager or email [support@zenoo.com](mailto:support@zenoo.com).

## Screening vs registry coverage

**Screening** (PEP, sanctions, adverse media) works globally. WorldCheck covers entities across all jurisdictions.

**Company registry** verification requires registry coverage for the specific country. Major markets (GB, US, IE, DE, FR, NL, AU, SG, HK) have full coverage. Some smaller jurisdictions may have limited or no registry access.

<Note>If you submit a Company Verification request for a jurisdiction without registry coverage, the company verification check will fail, but screening checks will still run.</Note>
