Generate Random IBAN

Mongolian IBAN generator

IBANs in Mongolia have 20 characters and start with MN. The one below is random, follows the national structure and passes the MOD-97 check, so form validation accepts it. No bank issued it.

Format

MN510005885597526440

New IBAN
  1. Country MN
  2. Check digits 51
  3. Bank code 0005
  4. Account number 885597526440
Generate a list Up to 100 IBANs, as CSV, JSON, SQL or plain text

In CSV, JSON and SQL, every IBAN segment (bank, branch, account, check digits) gets its own column.

MOD-97 valid

Realistic mode: real bank code, random account number. No bank issued this IBAN, but it could match a real account by chance. Never use it for payments.

Check an IBAN

Paste an IBAN from any country to check its length, format and check digits.

Mongolian IBAN format

Length, pattern and the position of each segment in MN IBANs, with a sample IBAN.

IBAN length 20
BBAN length 16
BBAN pattern 4n12n
Structure MNkk bbbb cccccccccccc
Example, electronic MN121234123456789123
Example, print MN12 1234 1234 5678 9123
Letters in the BBAN None, digits only
National check digits None

Position by position

Segment Positions Length Example
Country 1–2 2 MN
Check digits 3–4 2 12
Bank code 5–8 4 1234
Account number 9–20 12 123456789123

In the pattern, n stands for a digit, a for an uppercase letter and c for a letter or digit. The number before each letter is how many characters that block has.

Real bank codes in realistic mode

In realistic mode, the default, the generator takes the bank code from this list and keeps the account number random, so no bank issued these IBANs. With Realistic off, the bank code is random too.

Bank Bank code
Khan Bank 0005
Golomt Bank 0015

What to test with MN IBANs

  • Accept exactly 20 characters for MN, after removing spaces, and reject 19 or 21.
  • Digits only after the check digits: a validator for MN should reject any letter there.
  • Ready-made invalid values for negative tests: MN121234123456789124 (last character changed, MOD-97 fails) and MN12123412345678912 (one character missing).
  • Bank directory checks: by default the generator uses real bank codes such as 0015 (Golomt Bank), and random ones with Realistic off, so you can test a known and an unknown bank.

About IBANs in Mongolia

Mongolian IBANs have 20 characters and are fully numeric: a 4-digit bank code followed by a 12-digit account number. Under a 2020 order of the Bank of Mongolia, banks opened new accounts in this format from 1 January 2022 and stopped using the old account numbers from 1 November 2024. Mongolia's format entered the IBAN Registry in 2023.

Questions about IBANs in Mongolia

How long is an IBAN in Mongolia?

20 characters: the country code MN, two check digits and a national part (BBAN) of 16 characters.

What does an IBAN from Mongolia look like?

For example MN12 1234 1234 5678 9123. That is the print format, in groups of four. Forms and files usually take it without spaces: MN121234123456789123.

Can Mongolian IBANs contain letters?

No. After the check digits, MN IBANs contain only digits: the BBAN pattern is 4n12n.

Where is the bank code in Mongolian IBANs?

The bank code, at positions 5–8: 1234 in the registry example. By default (realistic mode) the generator uses real bank codes, such as 0005 for Khan Bank.

Will a test IBAN for Mongolia pass validation?

It passes the checks most forms run: country code, length, character format and MOD-97 check digits. In realistic mode, the default, the bank code is real too, so a bank directory check accepts it. An account lookup or a payee name check will not confirm it, because the account number is random.

Can I use a generated Mongolian IBAN to sign up for a service or receive money?

No. It is test data that no bank issued to you. Money sent to it is rejected or, if the number happens to belong to someone, reaches a stranger, and using it for a sign-up, a free trial or a direct debit is misuse. Your own IBAN is in your banking app and on your statements.
