BIC (BIC)
A BIC — Business Identifier Code, and still widely called a SWIFT code — identifies a financial institution in international payments. It is an ISO standard of eight or eleven characters, for which Swift is the registration authority. It identifies an institution, not an account.
Also called: SWIFT code · Business Identifier Code
The structure is fixed by ISO 9362. The first four characters are the institution’s own prefix, the next two the ISO 3166-1 country code, the next two a location suffix; an optional three-character branch identifier can be appended to identify a particular branch, department or unit. That is why a BIC is either eight or eleven characters, and why an eight-character BIC is often described as pointing at an institution’s head office. Swift is the ISO-appointed registration authority: it receives registration requests, assigns the code and publishes the data record.
In a cross-border payment the BIC answers the question “which institution?”, while an IBAN or a local account number answers “which account?”. In many countries the BIC can now be derived from the IBAN, which is why some payment forms stopped asking for it; in others it is still required, and routing without it fails.
Two things it is not. A BIC is not proof that an institution can receive a given currency, or that it holds a correspondent relationship that makes a particular route work — institutions have valid BICs and no usable path for the payment you want to send. And a BIC does not have to belong to a bank: ISO 9362 covers non-financial organisations that need an identifier for automated financial processing.
In practice
Having a BIC does not mean being on the Swift network in any operational sense, and it says nothing about whether a payment will arrive. Route feasibility is a correspondent banking question — which nostro accounts exist, in which currency — and the code is only the address on the envelope.
Example
A payment to an eight-character BIC lands at the institution's head office and is then routed internally. The same payment to the eleven-character version reaches the named branch directly. Both are valid; only one matches how that institution has asked to be addressed.
Commonly confused with
| Term | How it differs |
|---|---|
| IBAN | An IBAN identifies a specific account and carries the country and a check digit. A BIC identifies the institution. Most cross-border payments in IBAN countries need both, or an IBAN alone. |
| SWIFT | Swift is the messaging cooperative and network. The BIC is the identifier standard it administers, which is why the code is colloquially called a SWIFT code. |
| Routing number | A domestic identifier — the US ABA routing number, the UK sort code. It works inside one country's clearing system and is not interchangeable with a BIC. |

- SWIFTSWIFT is a cooperative messaging network that banks use to send each other standardized instructions about payments. It does not hold funds and it does not move them; the money moves separately, through the accounts banks keep with one another.
- IBANAn IBAN is a standardized account number format that wraps a domestic account identifier in a country code, check digits and a bank code, so a payment can be routed and structurally validated across borders. It is an address for an account, not a payment network.
- Correspondent BankingCorrespondent banking is an arrangement in which one bank holds deposits for another bank and makes and receives payments on its behalf, normally so the second bank can reach a currency or a market where it has no branch or license of its own.
- Nostro AccountA nostro account is an account a bank holds in a foreign currency at a bank in that currency’s home market, literally “our account with you.” It is how a bank keeps a working balance in a currency it cannot hold at its own central bank.
- Cross-Border PaymentA cross-border payment is one where the payer and the payee are in different jurisdictions. It usually involves a currency conversion and at least one intermediary, and it answers to the rules at both ends rather than only the sender’s.
- SWIFT GPISwift GPI is a service layer over existing correspondent banking that gives a cross-border payment a unique reference, end-to-end tracking, fee transparency and agreed service levels between participating banks. It is not a new payment rail, and it does not change how the money moves.
