What is an IBAN Number in Bulgaria?

An IBAN is an International Bank Account Number. In Bulgaria, it gives each bank account a standard international format so payment systems can read the country, bank, branch, account type, and account number correctly.

A Bulgarian IBAN starts with the country code BG and includes check digits, a four-letter bank code, branch code, account type, and account number. Some SEPA or international payments may also ask for the bank’s BIC or SWIFT code.

Yes, you'll usually need a Bulgaria IBAN to send or receive SEPA payments, international bank transfers, or cross-border business payments connected to a Bulgarian account. A local account number alone may not provide enough detail for overseas banks or payment software.
