The CLABE (Clave Bancaria Estandarizada) is a banking standard for the numbering of bank accounts in Mexico. This standard is a requirement for the sending and receiving of domestic inter-bank fund transfers since June 1, 2004. The CLABE account code has 18 digits. [1]

"CLABE" is an acronym for CLAve Bancaria Estandarizada, Spanish for Standardized Bank Code.

The CLABE replaces the old Mexican account numbering scheme where the account number had 11 digits.

The provision for CLABE standardization was issued by the Asociación de Bancos de México (ABM) (Spanish: Mexican Bank Association) in joint efforts with Banco de México (Mexico's Central Bank) and it guarantees that the inter-bank fund transfers, payroll deposits or automatic service charges are made to the correct accounts.



The 18 digits of the CLABE follows this structure: [1]

  • 3 Digits: Bank Code
  • 3 Digits: Branch Office Code
  • 11 Digits: Account Number
  • 1 Digit : Control Digit

Bank code

In Mexico, banking institutions are identified by a three-digit number assigned by the ABM, but a bank number catalogue is not available through the web. Here is a table, provided by FedACH International, as of July 31, 2006: [2]

Branch office code

This three-digit code is internal, bank-specific information.

Account number

The account number in the financial institution. Padded on the left with zeroes to a width of 11 digits.

Control digit

The control digit is calculated as the modulus 10 of 10 minus the modulus 10 of the sum of the modulus 10 of the product of the first 17 digits by its weight factor. [3][4]

The first 17 digits of the CLABE are, as mentioned above, the Bank Code, the Branch Office Code and the Account Number.

The weight factor of a given digit is:

  • 3 if its position (starting at 0) modulus 3 is 0
  • 7 if its position modulus 3 is 1
  • 1 if its position modulus 3 is 2

The method is:

  • For every digit, multiply it by its weight factor and take their modulus 10 (modulus is the Remainder of the integer division. The modulus X of a baseX number is its rightmost digit).
  • Sum all of the calculated products, and take modulus 10 again.
  • Subtract the sum to 10, take modulus 10, and you have the resulting control digit.

So, as an example:

Bank Branch Account Number
17 CLABE digits 0 3 2 1 8 0 0 0 0 1 1 8 3 5 9 7 1
Weight factors 3 7 1 3 7 1 3 7 1 3 7 1 3 7 1 3 7
= ( % 10 )
Products, modulus 10 0 1 2 3 6 0 0 0 0 3 7 8 9 5 9 1 7
Product sum, modulus 10 1
10 - sum, modulus 10 9 (control digit)

And so, the complete CLABE is: 032180000118359719
