Wanderlust World Wanderlust World A CLABE (Clave Bancaria Estandarizada) is an 18-digit standardized banking code used in Mexico for interbank transfers—similar to a U.S. routing number + account number combined.
Each account has a unique CLABE. The first 3 digits identify the bank (Santander = 014), next 3 the branch, next 11 the account, and the last a check digit. Sample institutional prefixes:
| Entity | Institutional Prefix (First 6 Digits) |
|---|---|
| Banco Santander (México) S.A. | 014XXX |
| Santander (Banca Afirme) | 012XXX |
| Santander (Banca Crecen) | 011XXX |
Note: The full 18-digit CLABE is unique per account. Never share it publicly. Use your bank's app or statement to find yours.
