Bank Codes Catalog (Mexico)

When registering a CLABE or activating a Direct Debit, the CLABE must belong to a participating banking institution. The bank code is automatically extracted from the first 3 digits of the 18-digit CLABE.
Below is a list of the supported banks for Direct Debit processing:

Bank not found?
If you need to process a CLABE from an institution that does not appear in this list, please contact our technical support team to verify the code's compatibility.
CLABE from non-participating banks will be rejected with error:
"The CLABE belongs to a bank (code XXX) not available for direct debit"
