Last night was probably the most terrifying night I’ve had since coming to Spain! I was casually checking my phone before bed when I saw several spending notifications pop up from the Santander bank app. They were all for transactions I knew nothing about, in a city I’ve never even been to. In that moment, my heart just sank. My first thought was: My bank account has been compromised! The money was just gone, right before my eyes. Although the amount wasn’t catastrophic, the feeling of helplessness was truly awful. I’m sure many friends living in Spain have worried about this, so I decided to write down my experience and the steps I took as a cautionary tale and hopefully to help anyone who might need it.

My Emergency Action Steps
When you discover your account has been compromised, don’t panic—time is money! I immediately took the following actions, a situation much more common for individuals than a major Spanish bank vault robbery.
- Immediately Lock/Cancel the Card: The very first thing I did was log into the Santander mobile banking app, find the “Bloquear tarjeta” (Block Card) function under card management, and locked it instantly. Almost all banking apps have this emergency feature. If you don’t have the app or are unfamiliar with the process, which can be stressful when dealing with Spanish bank card fraud, immediately call the bank’s 24-hour customer service hotline to report it. This number is usually printed on the back of your card.
- Take Screenshots as Evidence: I took screenshots of all the suspicious transaction records and spending notifications. This is crucial evidence for dealing with the bank and for the police report later.
- Contact Bank Customer Service: After locking the card, I still called the customer service hotline to formally report these unauthorized transactions. The representative guided me through a process, documented the situation, and told me what the next steps were.
Emergency Hotlines for Major Banks
For everyone’s convenience, I’ve compiled the hotlines for several major banks to report lost or stolen cards. It’s a good idea to save these in your phone, just in case.
| Bank Name | Hotline for Lost/Stolen Cards |
| Santander | 915 123 123 |
| BBVA | 900 102 801 |
| CaixaBank | 938 87 25 25 / 900 444 000 |
| Sabadell | 963 085 000 |
Follow-up and Filing a Police Report
The bank’s customer service told me that reporting the card was just the first step and that they would start an internal investigation. However, to make the claim official and increase the chances of getting the money back, they strongly recommended that I file a report at a police station. So, first thing this morning, I went to my local police station with all the screenshot evidence and records of my communication with the bank. After taking my statement, the police will give you a copy of the report (a “denuncia”). You then need to submit this report to the bank as official documentation for their dispute resolution process. My case has now been forwarded to the bank’s fraud department. They said the investigation will take some time, but because I acted quickly, there’s a high probability the funds will be recovered, which is a major concern in cases of bank card fraud. I’m hoping for a good outcome. What an expensive lesson learned. Everyone should be extremely careful with their bank card information, avoid entering card details on unsecured websites, and be cautious when using public Wi-Fi! I hope my experience can serve as a wake-up call for everyone!
