IBAN (IBAN)

An 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.

Also called: International Bank Account Number

An IBAN is a format, not a rail. It takes a domestic account number and adds a country code, two check digits and a bank identifier, so that a payment leaving one country can be routed and checked in another. The check digits catch typing errors. They say nothing about whether the account exists or who holds it.

The account behind an IBAN is not always in the country the code suggests. Electronic money institutions issue IBANs through a bank partner in whichever market that partner is licensed, so a customer in one country can hold an IBAN registered in another. An IBAN whose country does not match the customer’s stated location invites questions from compliance teams.

Name checking is a separate step. SEPA payments and UK transfers are increasingly matched against the beneficiary name on the account, so a correct IBAN with the wrong name can still be refused.

In practice

An IBAN identifies an account, not its owner. A payment can carry a structurally valid IBAN, pass every check digit, and still be rejected because the beneficiary name does not match the account.

Example

A supplier sends a euro invoice quoting an IBAN that begins DE. The payer’s bank validates the check digits and releases the payment. It comes back days later: the account is held in the name of a group treasury company, not the supplier named on the instruction. The IBAN was correct throughout.
