Bulgarian IBAN generator

IBANs in Bulgaria have 22 characters and start with BG. 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

BG31BPBI99205984866141

  1. Country BG
  2. Check digits 31
  3. Bank code BPBI
  4. Branch code 9920
  5. Account type 59
  6. Account number 84866141
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.

Position by position

Segment Positions Length Example
Country 1–2 2 BG
Check digits 3–4 2 80
Bank code 5–8 4 BNBG
Branch code 9–12 4 9661
Account type 13–14 2 10
Account number 15–22 8 20345678

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 Branch code
DSK Bank STSA 9300
UniCredit Bulbank UNCR 7000
Eurobank Bulgaria (Postbank) BPBI 9920

What to test with BG IBANs

  • Accept exactly 22 characters for BG, after removing spaces, and reject 21 or 23.
  • Letters are required at positions 5–8. Test lowercase input too, and convert it to uppercase before you validate.
  • Letters or digits at positions 15–22: a digits-only regex rejects valid BG IBANs. Realistic mode, the default, uses digits only there; with Realistic off, the generator puts letters there about half the time.
  • Ready-made invalid values for negative tests: BG80BNBG96611020345679 (last character changed, MOD-97 fails) and BG80BNBG9661102034567 (one character missing).
  • Bank directory checks: by default the generator uses real bank codes such as UNCR (UniCredit Bulbank), and random ones with Realistic off, so you can test a known and an unknown bank.

Questions about IBANs in Bulgaria

How long is an IBAN in Bulgaria?

22 characters: the country code BG, two check digits and a national part (BBAN) of 18 characters.

What does an IBAN from Bulgaria look like?

For example BG80 BNBG 9661 1020 3456 78. That is the print format, in groups of four. Forms and files usually take it without spaces: BG80BNBG96611020345678.

Can Bulgarian IBANs contain letters?

Yes. BG IBANs always have uppercase letters at positions 5–8: BNBG in the registry example. Letters or digits are allowed at positions 15–22, although the registry example has only digits there.

Where is the bank code in Bulgarian IBANs?

The bank code, at positions 5–8: BNBG in the registry example. The branch code is at positions 9–12 (9661). By default (realistic mode) the generator uses real bank codes, such as STSA for DSK Bank.

Will a test IBAN for Bulgaria 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 Bulgarian 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.
