Iban

.. versionadded:: 2.3
    The Iban constraint was introduced in Symfony 2.3.

This constraint is used to ensure that a bank account number has the proper format of an International Bank Account Number (IBAN). IBAN is an internationally agreed means of identifying bank accounts across national borders with a reduced risk of propagating transcription errors.
