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.
• allow_non_sepa: A boolean that limits allowable account numbers to SEPA countries when false

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

Sometimes 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 omitting the country_code option.

$validator = new Laminas\Validator\Iban();

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 must provide a country code. You can do this during instantiation via the option country_code.

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

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

Restrict to SEPA Countries

To only accept bank accounts from within the Single Euro Payments Area (SEPA), you can set the option allow_non_sepa to false:

$validator = new Laminas\Validator\Iban(['allow_non_sepa' => false]);

$validator->isValid('AT611904300234573201'); // true
$validator->isValid('BA391290079401028494'); // false
