Starting from 2025.04.01 all commercial banks, government and private financial institutions operating in Mongolia will switch to the International Bank Account Numbering (IBAN) standard by international standards. Please note that all customers are required to use the IBAN account number for interbank transactions.
However, for transactions between TDB accounts, it is not necessary to use an IBAN account number and the current account number will be still used.
IBAN (International Bank Account Number) is a 20-digit customer account number generated according to the ISO13616-1,2 standard that can be used for interbank and international transactions.
Advantages of using IBAN account numbers:
Easily check whether the account number is correct.
Immediately identify which bank account it is.
Transaction returns due to incorrect accounts will be reduced.
Please inquire your IBAN account at TDB through the following channels.
