Steps to validate an IBAN
There are two different validations that can be performed to ensure an UK IBAN is correct.
- 01First validation is done using the IBAN's Check Digits using the MOD97 algorithm.
- 02Second layer of validation can be carried out on the domestic sort code and account number combination
- 03Match the sort code against our Bank and Branch code directory to check if it exists
Found the correct IBAN, What to do next
With a Spanish IBAN to hand, run through these checks before sending.
- 01Confirm the registered beneficiary name with the Spanish bank. Verification of Payee applies across the eurozone.
- 02SEPA transfers need only the IBAN. For inbound non-SEPA payments, pair the IBAN with the BIC.
- 03Choose between SEPA Credit Transfer and SEPA Instant Credit Transfer. Spain is Europe's leading SCT Inst market by volume.
- 04For consumer-facing payments inside Spain, Bizum dominates P2P and increasingly e-commerce, with over 25 million users.
- 05Confirm the account holds EUR. Most Spanish banks support multi-currency for international clients.

IBAN Rules in Spain
- 01IBAN is mandatory in Spain for every domestic and cross-border credit transfer, in force since SEPA migration.
- 02The 24-character Spanish IBAN begins with ES, two check digits, a 4-digit bank code, a 4-digit branch code, two national check digits, and a 10-digit account number. The last 20 digits are the legacy CCC (Codigo Cuenta Cliente).
- 03The legacy CCC is embedded inside the IBAN and is no longer used standalone. Spain is in the eurozone and a full SEPA member. The same Spanish IBAN works for every domestic Spanish payment, every SEPA destination, and inbound SWIFT wires.
