CLABE explanation

The CLABE (Clave Bancaria Estandarizada) is a standard for bank accounts in Mexico. This standard has been a requirement for sending and receiving of domestic inter-bank fund transfers since June 1, 2004. The CLABE account code has 18 digits and replaces the old Mexican account-numbering scheme where the account number had 11 digits. There is a CLABE for each of your accounts. The provision for CLABE standardization was issued by the Asociación de Bancos de México (Mexican Bank Association) in a joint effort with Banco de México (Mexico's Central Bank). It guarantees that inter-bank fund transfers and automatic service charges are made to the correct accounts.
