Unique account identifier

What is the unique account identifier and what is it for?

The unique account identifier is a code that allows a bank account to be recognised unequivocally.

It can consist of numbers only or of a combination of numbers and letters.

The unique account identifier used in Spain and other SEPA countries is the  IBAN  (International Bank Account Number).

When making a bank transfer, it is essential to provide the recipient’s correct account identifier (the IBAN in SEPA countries), as the sender’s bank will automatically execute the transfer based on this information, without further verifying either the sender or the recipient.

Consequently, other data included in the transfer order (e.g. the payment reference) are for the recipient only, not for the bank.
