/**
* International Bank Account Number (IBAN).
*
* Uniquely identifies the account of a customer at a financial institution as
* defined in ISO 13616
*
* Length 0-34 bytes
*
* IBAN - International Bank Account Number. Often (incorrectly) referred to as
* IBAN Number. An unique account identifier for every bank account in Europe,
* supervised by SWIFT. The IBAN system was originally intended for use within
* Europe, and its use is largely confined thereto: most notably, the USA does
* not participate. Among British dependencies, only Gibraltar assigns IBANs.
* All of Europe does however participate with the exception of the CIS
* countries: Turkey uses IBANS and so do some African countries. The number
* consists first of a two-digit country identifier, followed by two check
* digits, then up to 30 characters representing the local account. The number
* of characters varies from country to country, but is fixed for each country.
* When used electronically there are no spaces in IBANs, but the convention on
* paper is to separate into groups of four with any odd digits in the last
* group.
