Starting from 2025.04.01 all commercial banks, government and private financial institutions operating in Mongolia switched to the International Bank Account Numbering (IBAN) standard by international standards. So, please note that:

• Interbank transactions must be done using the IBAN number.

However, for transactions between accounts within TDB or within the bank, the old account number can be still used, and there is no need to use the IBAN number.

Advantages of using IBAN account numbers:

• Easy to check whether the account number is correct.

• Immediately identify which bank account it is.

Transaction returns due to incorrect accounts will be reduced.
