How can I generate IBAN for Swedish Account number

Problem statement I have a Swedish Bank (SEB) account number and I need to generate the IBAN for this account number (in java code)

A possibility I can see that it's possible if I use website: https://www.ibancalculator.com/

What I tried https://github.com/arturmkrtchyan/iban4j

Iban iban = new Iban.Builder()
                .countryCode(CountryCode.SE)
                .bankCode("XXXX")
                .accountNumber("XXXXXXX")
                .build();

Here X is a digit in my account number and the account number is overall 11 digits long (first 4 are clearing number and next 7 is account number).

However, when I try this, I get the following: length is 11, expected BBAN length is: 20

Can someone please point out what am I doing wrong here OR is there some other better way.

P.S. If I use same values on the ibancalculator.com, I get the correct IBAN for my account.

Solution

  • The error you obtain gives a hint that you need to use full length of the account number as indicated in this example:

    Iban iban = new Iban.Builder()
            .countryCode(CountryCode.SE)
            .bankCode("500")
            .accountNumber("0000005839825746")
            .build();

    In other words, ensure that you are supplying expected 20 digits before calling .build().
