Question 1

Do you still need a BIC?

Accepted Answer

Inside SEPA, most euro transfers no longer require one: the IBAN alone is enough. You will still be asked for a BIC on many international transfers, older payment forms and some payroll or invoicing systems.

Question 2

BIC or SWIFT code?

Accepted Answer

The same thing. BIC is the official name (Business Identifier Code, ISO 9362); SWIFT is the organisation that issues them, so the code is often called a SWIFT code.

Question 3

Why can’t a BIC be calculated from an IBAN?

Accepted Answer

An IBAN contains a national bank identifier, not the BIC. The two are linked by directories that each country’s central bank or payments body maintains, which is what this tool looks up.
