Belgian IBAN generator
IBANs in Belgium have 16 characters and start with BE. The one below is random, follows the national structure and passes the MOD-97 check, so form validation accepts it. No bank issued it.

- Country BE
- Check digits 64
- Bank code 103
- Account number 9787575
- National check 52
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.
Test data only. No bank issued this IBAN. 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.
Without JavaScript, this form opens the full IBAN validator. Checked in your browser. The IBAN is not sent anywhere and not stored.

Position by position
| Segment | Positions | Example |
|---|---|---|
| Country | 1–2 | BE |
| Check digits | 3–4 | 68 |
| Bank code | 5–7 | 539 |
| Account number | 8–14 | 0075470 |
| National check | 15–16 | 34 |
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.
National check digits
Besides the two IBAN check digits, BE IBANs carry national check digits inside the BBAN, at positions 15–16. They come from the domestic account number and follow a national rule.
The last two digits are the remainder of the first ten digits divided by 97, with 97 in place of 0.
This generator calculates them with the official algorithm, in both modes, so validators that check them accept the IBANs on this page.

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 |
|---|---|
| BNP Paribas Fortis | 001 |
| BNP Paribas Fortis | 230 |
| KBC | 734 |
| KBC | 431 |
| Belfius | 068 |
| ING Belgium | 310 |
| ING Belgium | 363 |
| Argenta | 973 |
| Crelan | 103 |
| Crelan (ex AXA Bank) | 750 |
What to test with BE IBANs
- Accept exactly 16 characters for BE, after removing spaces, and reject 15 or 17.
- Digits only after the check digits: a validator for BE should reject any letter there.
- For a negative test of the national check, change the character at position 15 and recalculate the IBAN check digits (the validator suggests them). The IBAN then passes MOD-97 but fails the national check.
- Ready-made invalid values for negative tests: BE68539007547035 (last character changed, MOD-97 fails) and BE6853900754703 (one character missing).
- Bank directory checks: by default the generator uses real bank codes such as 230 (BNP Paribas Fortis), and random ones with Realistic off, so you can test a known and an unknown bank.
About IBANs in Belgium
Belgian IBANs are 16 characters long, the shortest format in the European Union. The BBAN is the familiar 12-digit Belgian account number: a 3-digit bank code, a 7-digit account number and two national check digits, which are the remainder of the first ten digits divided by 97 (97 when the remainder is 0).
Questions about IBANs in Belgium
How long is an IBAN in Belgium?
16 characters: the country code BE, two check digits and a national part (BBAN) of 12 characters.
What does an IBAN from Belgium look like?
For example BE68 5390 0754 7034. That is the print format, in groups of four. Forms and files usually take it without spaces: BE68539007547034.
Can Belgian IBANs contain letters?
No. After the check digits, BE IBANs contain only digits: the BBAN pattern is 3n7n2n.
Where is the bank code in Belgian IBANs?
The bank code, at positions 5–7: 539 in the registry example. By default (realistic mode) the generator uses real bank codes, such as 001 for BNP Paribas Fortis.
Will a test IBAN for Belgium pass validation?
It passes the checks most forms run: country code, length, character format and MOD-97 check digits. The national check digits inside the BBAN are computed with the official algorithm, so a validator that also checks them accepts this IBAN. 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 Belgian 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.
