Short answer
IBAN identifies an account using an international format; BIC identifies an institution and is commonly called a SWIFT code. They are not interchangeable and not every country uses IBAN. Request bank or provider instructions for the specific currency and route, confirming holder and account: valid format does not establish the recipient.
Key verification: Match details against current instructions and a known recipient channel before authorising a transfer.
Sources and limitationsA foreign supplier may request IBAN, BIC, an account number or local codes. Different identifiers from your usual account do not necessarily mean details are missing. Understand the payment route and request its instructions rather than intuitively converting one field into another.
IBAN identifies an account, BIC an institution
The Wise IBAN guide explains its structure and warns that valid format guarantees neither existence nor the correct account. Format depends on country; not every country uses IBAN.
Swift describes BIC as an institution identifier. Although commonly called a SWIFT code, a BIC does not mean every institution connects to the same messaging service. It does not replace the beneficiary account number.
Which details to request for the route
| Detail | What it identifies | Check |
|---|---|---|
| Holder | Named beneficiary | Matches current instructions |
| IBAN or local account | Receiving account | Accepted format and route |
| BIC or another banking code | Institution or system-specific route | Provider requests that detail |
| Currency | Unit of received amount | Account and route support it |
| Reference | Payment identification | Recipient instructions |
This worksheet is an editorial proposal. Banks may need additional fields. Do not fill a local code with a BIC merely because both identify institutions: each system expects its specific data type.
Local and international instructions may differ
A multicurrency account may show different details by currency and receipt method. Wise explains this in its account details guidance. Confirm account availability and terms; do not copy a general page's details as instructions to pay someone.
If a form requests fields absent from instructions, consult the bank or provider. Do not derive a supposed IBAN from incomplete information or invent an intermediary bank. The recipient should provide the appropriate route.
Validate format and recipient separately
A checker may detect incorrect length or structure without establishing ownership or payment obligation. Confirm emailed instruction changes through an already-known contact. A phone number newly included in the same message is not independent verification.
Retain who confirmed changes and the authorised instruction reference. Use beneficiary verification controls offered by your institution under their own conditions. Do not promise any validation will recover an incorrect transfer.
Fictional example and choice limits
An agency receives an invoice in another currency. The supplier provides local details, but the selected route's form requests another field. The agency enquires before sending; it does not substitute numbers from another account merely to make the form accept payment.
Wise may fit where it supports the route under suitable terms. Its invitation does not establish particular benefits or Business eligibility. CallsIQ has neither validated actual accounts nor executed this example; the worksheet gathers information rather than guaranteeing arrival, cost or timing.
