In order to fully validate an Spanish IBAN you have to validate as well the country specific part as a valid CCC. It was used for home banking transactions until February 1st 2014 when IBAN codes started to be used as an account ID. The CCC has 20 digits, all being numbers: EEEE OOOO DD NNNNNNNNNN * EEEE: banking entity * OOOO: office * DD: check digits * NNNNN NNNNN: account identifier This module does not check if the bank code to exist. Existing bank codes are published on the 'Registro de Entidades' by 'Banco de España' (Spanish Central Bank).
