SEPA (‘Single Euro Payments Area’) covers 41 European countries, including some outside the EU (country list as of 22 May 2025). An instant transfer reaches the recipient there within ten seconds.[1]

Since 9 October 2025, banks in the euro area have had to be able to send instant transfers at any time, including at night and at weekends – at no higher price than a normal transfer. Your bank also checks, free of charge, whether the recipient’s name matches the IBAN, and warns you if it doesn’t.[2]

How to use SEPA when buying bitcoin

  • Paying in: transfer from an account in your own name – providers usually reject payments from other people’s accounts (part of the GlossaryKYC (Know Your Customer)The obligation of regulated providers to identify you before the business relationship starts and to ask, for example, about its purpose and, where necessary, the source of your money. In Germany, the legal basis is the Money Laundering Act (GwG).On the learning path: Stage 4 · Step 3 – Buying Bitcoin →In the glossary → check). If the provider gives you a personal reference, put it in the payment reference so it can match the payment to you.
  • Savings plan: depending on the provider, by direct debit, by a standing order at your bank or from a euro balance held with the provider.
  • Selling: the proceeds arrive in your bank account by SEPA transfer.

Paying by card usually costs extra – examples are in Understanding fees.
