SWIFT / BIC

When you send money across borders, the bank needs to know exactly which institution should receive it. That’s what a BIC (Bank Identifier Code) does: it identifies a specific bank, and sometimes a specific branch. SWIFT is the messaging network that carries the instruction between banks, which is why people say “SWIFT code” and “BIC” as if they mean the same thing. In practice, they do.

A code runs to 8 characters for a bank’s head office, or 11 when it points to a specific branch. You’ll usually pair it with an IBAN so the money lands in the right account at the right bank.

This matters the moment you move countries. Your salary, a deposit refund, a tax rebate, or money from selling something back home often has to cross a border, and an international transfer needs the BIC. Inside the eurozone, a SEPA payment can be cheap or free and may not ask for a BIC at all, but a true cross-border or cross-currency transfer almost always does.

Here’s the catch people miss. SWIFT transfers can carry hidden costs. Each intermediary (“correspondent”) bank along the way may take a cut, so less arrives than you sent, and the exchange rate your bank applies can be poor. A multi-currency account often avoids this by holding local details in several countries, letting you receive money like a local instead of paying for each wire. If you’re choosing where to bank as a mover, the banking-picker can help you compare.

Where you’ll meet this

• Setting up a salary or invoice payment from an employer or client in another country, who asks for your IBAN and BIC.
• Reading the fee breakdown on an incoming international transfer and noticing the amount received is lower than expected.
• Filling in a foreign tax authority’s refund form or a landlord’s deposit return, where the BIC field is required.
