I recently moved to Spain and finally got my bank account sorted and received my much-awaited bank card. I thought it would be a happy occasion, but I almost got tripped up by the PIN code. I’m sharing my experience today, hoping it helps other newcomers. I’d also love to hear if anyone has had similar experiences.
Your Bank Card and PIN Arrive Separately
I opened my account with CaixaBank, and the teller told me the card would be mailed to my home. I received the card about a week later, but the envelope only contained the card, no password! I panicked, thinking it was lost or there was a security issue. It wasn’t until three or four days later that I received another separate letter. Inside was a tear-open slip of paper with my initial PIN. I’ve heard that BBVA and Santander usually do the same thing—for security reasons, the card and PIN are never sent in the same envelope. So, when it comes to Spanish bank card PINs, if you’ve only received your card, don’t panic, just be patient and wait a bit longer! This is a key difference compared to PIN codes you might be used to.

The PIN is 4 Digits, Not 6!
This is something I really need to emphasize! In my home country, I was used to 6-digit transaction passwords, so when I got the 4-digit PIN, I checked it several times, feeling it wasn’t secure enough. Later, when I went grocery shopping and used my card for the first time by inserting it into the POS terminal, it prompted for a PIN. I instinctively tried to enter six digits, but it wouldn’t accept them. That’s when I realized that here in Spain, it’s just four digits. This PIN is crucial; you’ll need it for most transactions, whether it’s withdrawing cash from an ATM or making a purchase in a store.
Many of you might want to change this initial, randomly generated PIN to something easier to remember. It’s actually quite simple to do at your bank’s ATM. On the main screen, you’ll usually find options like “Más opciones” (More Options) or “Gestión de claves” (Password Management). From there, select “Cambio de PIN” (Change PIN), enter your old PIN, and then enter your new 4-digit PIN twice to confirm. The ATM interfaces are typically available in multiple languages, which is very convenient.
Here’s a quick summary and comparison to help you understand how the PIN is used in different scenarios:
| Scenario | Is a PIN Required? | Notes |
| In-store Chip & PIN Payment | Yes | Almost always required; it’s the main verification method. |
| In-store Contactless Payment | May not be required for small amounts | Usually contactless is PIN-free for amounts under €20 or €50, but you might be randomly prompted for a PIN for security checks. |
| ATM Withdrawal/Inquiry | Yes | The first step for any ATM transaction is to verify the PIN. |
| Online Shopping | Usually not | Online payments typically rely on the CVV code and an SMS verification code sent to your phone. |
Living in Spain, it’s essential to get used to and remember your 4-digit PIN. Has anyone else encountered any interesting or tricky situations with their bank cards? Feel free to share and discuss in the comments below!
