A BIC/SWIFT code identifies a bank on international payment networks. When you send money outside standard SEPA euro transfers, this code helps ensure your payment reaches the right institution, not just the right account number.

What is a BIC/SWIFT code for payments?

BIC (Bank Identifier Code) and SWIFT code refer to the same 8- or 11-character bank address used on the SWIFT network. Payment systems use it together with an account number or IBAN to route cross-border transfers. You will see it on bank statements, in transfer forms, and in the bunq app when an international payment requires it.

For a full breakdown of the format and characters, see BIC/SWIFT Code in the glossary. This page focuses on when you need it at checkout versus transfers.

When you need a BIC/SWIFT code

You typically need a BIC/SWIFT code when:

Sending a SWIFT transfer outside the SEPA zone or in a non-euro currency

A recipient bank or intermediary asks for it on a wire form

Some countries still require BIC alongside IBAN even for certain cross-border euro payments

For everyday euro transfers between SEPA countries, you usually only need the recipient’s IBAN. The bank derives the BIC from the IBAN in the background.

BIC/SWIFT vs. IBAN in a paymentThink of them as complementary:

IBAN points to a specific account.

BIC/SWIFT points to the bank (and sometimes a branch) that holds that account.

Card payments at a shop do not use BIC/SWIFT; those use card networks. BIC/SWIFT matters for account-to-account international wires and some business payment files.

Sending payments with bunqbunq supports international transfers and multi-currency accounts. When a payment needs a BIC, you will find bunq’s BIC with your account details in the app. Use Payments for SEPA and instant transfers in euros, and check zero-fx when spending or converting foreign currencies.

Common questions

Is SWIFT the same as SEPA?No. SEPA is a European euro payment area with its own rules. SWIFT is a global messaging network for international transfers. SEPA payments use IBANs inside Europe; SWIFT payments often need BIC and may take longer.

Where do I find bunq’s BIC?

Open your Bank Account in the app. Your IBAN and BIC appear together for sharing with payers or for outgoing international transfers.

What happens if the BIC is wrong?

The transfer may be delayed, rejected, or routed incorrectly. Always verify the BIC with the recipient or their bank before sending, especially on large amounts.
