What is a CLABE?

The CLABE (Standardized Banking Code) is an 18-digit number that uniquely identifies each bank account in Mexico. It is mandatory for electronic transfers and automatic payments (SPEI).

Structure of the CLABE:

  • Digits 1-3: Bank code (Example: 002 = Banamex, 014 = Santander)
  • Digits 4-6: Branch or office (generally 000 for modern accounts)
  • Digits 7-17: Unique account number
  • Digit 18: check digit (modulo 10 algorithm)

What validates this tool?

  • ✅ Correct 18-digit format
  • ✅ Valid bank code
  • ✅ Check digit using a mathematical algorithm
  • Does not verify if the account exists or has funds

Important:

This tool only validates the format and mathematical structure of the CLABE. It does not confirm if the bank account is active nor if it belongs to a specific person. To verify ownership, contact the bank directly.
