What is a CLABE Number in Mexico?

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.

CLABE format

The 18 numeric digits of the CLABE :
  • 3 Digits: Bank Code
  • 3 Digits: Branch Office Code
  • 11 Digits: Account Number
  • 1 Digit : Control Digit
When preparing to send money via bank deposit to Mexico, it is strongly recommended that you contact your recipient to confirm their name as it appears on their account, the bank's name and the CLABE.
