Bizum is a mobile payment system used in Spain that lets you send money to anyone using just their phone number. It works directly through your bank’s app, with no separate account or additional downloads required. Think of it as Spain’s answer to peer-to-peer payment apps, but built into the banking system itself rather than sitting on top of it.
How Bizum Works
Bizum connects your phone number to your bank account. Once you activate the service through your bank’s mobile app, your phone number becomes your payment address. To send money, you select Bizum within your banking app, enter the recipient’s phone number, and confirm the amount. The money moves directly between bank accounts, typically arriving in seconds.
Because Bizum is integrated into the banking system rather than operating as a standalone app, there’s nothing extra to install. You open the same banking app you already use, find the Bizum option, and you’re ready to go. This also means the transaction draws from (or deposits into) your regular bank account, not a separate wallet you’d need to top up or cash out.
The system works across banks. You can send money to someone at a completely different financial institution, and it still arrives almost instantly. More than 30 banks and financial institutions in Spain participate, including CaixaBank, Santander, BBVA, Sabadell, ING, Bankinter, Openbank, and many smaller regional banks and credit unions. You don’t need to switch banks or open a new account to use it.
Transaction Limits
Bizum caps individual transactions at €1,000. The minimum you can send or receive is €0.50. Beyond the per-transaction cap, there are also rolling limits: you can send up to €2,000 per day and €5,000 per month. These limits apply to outgoing payments. If you’re splitting dinner or collecting rent from roommates, those caps are worth keeping in mind for larger amounts.
Paying at Online Stores
Bizum isn’t limited to sending money between friends. Many online retailers in Spain accept it as a checkout option. The process is straightforward: select “Pay with Bizum” at checkout, enter the phone number linked to your Bizum account, then open your banking app when the confirmation notification arrives. You verify the details and approve the payment, then return to the merchant’s site to complete your order.
This eliminates the need to type in card numbers, expiration dates, or CVV codes when shopping online. For people wary of entering card details on unfamiliar websites, it offers an extra layer of separation since the merchant never sees your bank account or card information.
Security Features
Bizum doesn’t operate through its own standalone app, which is actually a security advantage. Every transaction runs through your bank’s app, meaning it benefits from the same security protections your bank already has in place: login credentials, biometric authentication, and the bank’s own fraud monitoring systems. On top of that, Bizum transactions require a one-time password (OTP) sent to your phone via SMS, adding a second verification step before money moves.
One critical detail to understand: Bizum payments are irrevocable. Once you confirm a transaction, it cannot be cancelled or reversed. According to the Banco de España, transfers made through Bizum are final. If you send money to the wrong number or the wrong amount, your only recourse is to contact the recipient directly and ask them to send it back. You can also reach out to your bank and ask them to attempt recovery, but there’s no guarantee. This makes it especially important to double-check phone numbers and amounts before hitting confirm.
How to Set Up Bizum
Getting started takes just a few minutes. Open your bank’s mobile app and look for the Bizum option, which is usually found in the transfers or payments section. You’ll be asked to link your phone number to the service. Once activated, that phone number becomes your Bizum identifier across the entire network.
You can only register one phone number with one bank account at a time. If you have accounts at multiple banks, you’ll need to choose which one handles your Bizum transactions. Switching later is possible, but you’d need to deactivate Bizum at one bank before activating it at another.
Who Uses Bizum and Why
Bizum has become deeply embedded in everyday life in Spain. Its most common use is splitting bills: restaurant tabs, group gifts, shared household expenses, or paying someone back for concert tickets. Because nearly every major Spanish bank supports it, the odds that both sender and recipient already have access are high.
The system is particularly popular because it removes the friction of traditional bank transfers. You don’t need to ask anyone for their IBAN (the long account number used for European bank transfers), remember it, or type it correctly. A phone number is easier to share, easier to remember, and harder to get wrong.
For small businesses and freelancers, Bizum can serve as a quick payment method for low-value transactions, though the €1,000 per-transaction limit makes it impractical for larger invoices. Its real strength is convenience for everyday personal payments, where speed matters more than moving large sums.
