# CountryCode
|
|
|
|
- `CountryCode()`
|
|
- `CountryCode(string $set)`
|
|
|
|
Validates whether the input is a country code in [ISO 3166-1][] standard.
|
|
|
|
```php
|
|
v::countryCode()->validate('BR'); // true
|
|
|
|
v::countryCode('alpha-2')->validate('NL'); // true
|
|
v::countryCode('alpha-3')->validate('USA'); // true
|
|
v::countryCode('numeric')->validate('504'); // true
|
|
```
|
|
|
|
This rule supports the three sets of country codes:
|
|
|
|
- ISO 3166-1 alpha-2 (`'alpha-2'` or `CountryCode::ALPHA2`)
|
|
- ISO 3166-1 alpha-3 (`'alpha-3'` or `CountryCode::ALPHA3`)
|
|
- ISO 3166-1 numeric (`'numeric'` or `CountryCode::NUMERIC`).
|
|
|
|
When no set is defined the rule uses `'alpha-2'` (`CountryCode::ALPHA2`).
|
|
|
|
This rules uses data from [iso-codes][].
