Just arrived in Spain and feeling overwhelmed by all the terms and numbers related to your bank account, just like I was? From IBAN and SWIFT/BIC to that long string of digits on your card, it can be nerve-wracking every time you need to make a transfer or set up a payment, fearing one wrong digit will send your money into the void. Today, I’m going to break down the secrets of these Spanish bank account numbers, hoping to help out other friends who are just as confused.

IBAN: Your “National ID” for Domestic Transactions in Spain
IBAN (International Bank Account Number) is the number you’ll use most frequently for domestic transfers and receiving money within Spain. It typically starts with ‘ES’ followed by 22 digits. Whether you’re receiving your salary, paying rent, or setting up direct debits for utility bills, this is the number you’ll need. It’s usually not printed on the physical bank card; you’ll have to find it by logging into your online banking or mobile app under account details. Don’t mix it up with your card number!
- ES: Represents the country code for Spain.
- XX: Two check digits, automatically generated by the banking system to prevent errors.
- XXXX XXXX XX XXXXXXXXXX: These following 20 digits are your original domestic Spanish bank account number, which includes the bank code, branch code, check digits, and your personal account number.
PAN: The Long Number on Your Physical Card
PAN (Primary Account Number) is the 16-digit number printed on the front of your bank card. This is the number you enter when shopping online or linking your card to Apple Pay or Google Pay. Remember, this number is extremely sensitive! Never share it with anyone, especially the CVV code and expiration date on the back, or your card could be compromised. When paying online, always make sure the website is legitimate and secure.
SWIFT/BIC: The “Postal Code” for International Transfers
SWIFT Code, also known as BIC (Bank Identifier Code), is an international bank code. If you need to send money from your home country to your Spanish account, or transfer funds from Spain to a country outside the Eurozone, you’ll need to provide this code in addition to the IBAN. It acts as a unique address for the bank within the international financial network, ensuring your money reaches the correct institution without a hitch. Each bank has a fixed SWIFT/BIC, which you can easily find on the bank’s official website or by asking your account manager.
| Use Case | Primary Number Used | Notes |
| Domestic (Spanish) transfers/payments | IBAN | Most common, e.g., paying rent, receiving salary |
| Online shopping/linking payment methods | PAN | Requires expiration date and CVV code |
| International cross-border transfers | IBAN + SWIFT/BIC | Required for transfers to/from non-Eurozone countries |
Understanding the differences and uses of these numbers will make handling your banking in Spain much smoother. The process of getting a Spanish bank card might seem a bit complex at first, but you’ll get used to it after a few times. I hope this post helps everyone.
