What Is a SWIFT Code? Understanding International Bank Transfers

A SWIFT code, commonly called a BIC (Business Identifier Code), helps identify a financial institution or another eligible entity in cross-border financial messaging. It is not the same as an account number, IBAN, routing number, or card number. The information required for an international payment depends on the destination country, receiving bank, currency, and transfer route.

What does a BIC look like?

A standard BIC is commonly eight or eleven characters. Its components identify the institution, country, location, and optionally a branch. Because a code can be confused with another bank’s code, verify it using the receiving institution’s official instructions rather than a random directory.

What details may be required?

A sender may need the beneficiary’s full name, account number or IBAN where applicable, receiving bank name, SWIFT/BIC, address information, payment purpose, and sometimes intermediary-bank details. Not every country uses IBAN, and not every transfer requires an intermediary bank.

Fees and exchange rates

International payments may involve sender fees, receiving-bank fees, intermediary charges, and currency conversion spreads. The amount the recipient receives may therefore differ from the amount the sender expected. Ask the bank about available fee options, expected delivery time, and how the exchange rate is determined.

How to avoid mistakes

  • Confirm the recipient’s details through a trusted channel.
  • Check the currency and amount before approval.
  • Be cautious if a supplier suddenly changes bank details by email.
  • Keep the payment reference and receipt.
  • Ask the bank about trace or recall options if a transfer is delayed or misdirected.

SWIFT is not a guarantee of payment

A valid BIC identifies an institution in the messaging system; it does not prove that a recipient is trustworthy or that a transfer will be approved. Banks can still apply compliance checks and may request supporting documents.

Always use verified payment instructions from the receiving bank or beneficiary. This guide is general information; transfer requirements vary by country and institution.
