CountryCode

• CountryCode()
• CountryCode(string $set)

Validates whether the input is a country code in ISO 3166-1 standard.

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).
