Swedish IBAN generator

IBANs in Sweden have 24 characters and start with SE. 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

SE8392793027450490880361

  1. Country SE
  2. Check digits 83
  3. Bank code 927
  4. Account number 93027450490880361
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.

Position by position

Segment Positions Length Example
Country 1–2 2 SE
Check digits 3–4 2 45
Bank code 5–7 3 500
Account number 8–24 17 00000058398257466

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
SEB 500
Swedbank 800
Handelsbanken 600
Nordea 300
Danske Bank 120
Länsförsäkringar Bank 902
ICA Banken 927
SBAB Bank 925

What to test with SE IBANs

  • Accept exactly 24 characters for SE, after removing spaces, and reject 23 or 25.
  • Digits only after the check digits: a validator for SE should reject any letter there.
  • Ready-made invalid values for negative tests: SE4550000000058398257467 (last character changed, MOD-97 fails) and SE455000000005839825746 (one character missing).
  • Bank directory checks: by default the generator uses real bank codes such as 800 (Swedbank), and random ones with Realistic off, so you can test a known and an unknown bank.

About IBANs in Sweden

Swedish IBANs are 24 characters long and numeric: a 3-digit bank code followed by a 17-digit account number. Domestic Swedish account numbers have different lengths depending on the bank, so ask the bank for the IBAN instead of building it yourself.

Questions about IBANs in Sweden

How long is an IBAN in Sweden?

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

What does an IBAN from Sweden look like?

For example SE45 5000 0000 0583 9825 7466. That is the print format, in groups of four. Forms and files usually take it without spaces: SE4550000000058398257466.

Can Swedish IBANs contain letters?

No. After the check digits, SE IBANs contain only digits: the BBAN pattern is 20n.

Where is the bank code in Swedish IBANs?

The bank code, at positions 5–7: 500 in the registry example. By default (realistic mode) the generator uses real bank codes, such as 500 for SEB.

Will a test IBAN for Sweden 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 Swedish 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.
