IBAN format in Belarus: structure, length and example
An IBAN in Belarus is 28 characters long and always starts with BY. Payment routing, charges and any currency conversion depend on the sending and receiving banks. Confirm the route and the charges before you send. The details below come from the official IBAN registry maintained by SWIFT as registration authority for ISO 13616.
IBANs run from 15 to 33 characters worldwide, so at 28 this one sits above the average of 24. 11 other countries use the same length, which is why the two opening letters matter — they are what tells the sending bank where the money is going. There is no separate branch identifier: the number points at the bank and the account, not at a particular office. The format has been in force since July 2017.

How to send money to an account in Belarus
- Ask for the IBAN in full — including the country code at the front. Spaces do not matter; banks strip them.
- Check the name matches the account. The check digits catch typing mistakes, not wrong recipients.
- Send — and keep the reference number until the recipient confirms arrival.

It depends on the route and on the sending bank. Ask whether a BIC/SWIFT code is needed alongside the IBAN before you send.

Where this data comes from
Structure, length and examples come from the official IBAN Registry published by SWIFT as registration authority for ISO 13616, snapshot of 2026-08-21. Worked examples are derived from the registry's own sample values. Whether a country is inside SEPA is taken from the European Payments Council list of countries in the SEPA schemes, not from the registry: the registry records the position at its own release date and lags behind admissions.
