Iban Validator

Laminas\Validator\Iban validates if a given value could be a IBAN number. IBAN is the abbreviation for "International Bank Account Number".

Supported options

The following options are supported for Laminas\Validator\Iban:

  • country_code: Sets the country code which is used to get the IBAN format for validation.

IBAN validation

IBAN numbers are always related to a country. This means that different countries use different formats for their IBAN numbers. This is the reason why IBAN numbers always need a country code. By knowing this we already know how to use Laminas\Validator\Iban.

Ungreedy IBAN validation

Sometime it is useful just to validate if the given value is a IBAN number or not. This means that you don't want to validate it against a defined country. This can be done by using false as locale.

$validator = new Laminas\Validator\Iban(['country_code' => false]);
// Note: you can also provide FALSE as the sole parameter

if ($validator->isValid('AT611904300234573201')) {
    // IBAN appears to be valid
} else {
    // IBAN is not valid
}

In this situation, any IBAN number from any country will considered valid. Note that this should not be done when you accept only accounts from a single country!

Region aware IBAN validation

To validate against a defined country, you just provide a country code. You can do this during instaniation via the option country_code, or afterwards by using setCountryCode().

$validator = new Laminas\Validator\Iban(['country_code' => 'AT']);

if ($validator->isValid('AT611904300234573201')) {
    // IBAN appears to be valid
} else {
    // IBAN is not valid
}
