Builder fails for cz accounts

[PavelNiedoba]

new Iban.Builder().countryCode(CountryCode.CZ).bankCode("2010").accountNumber("2300121591").build().toString(); should be smart enough to work without leading zeroes for accountNumber

fails with org.iban4j.IbanFormatException: [20102300121591] length is 14, expected BBAN length is: 20 at org.iban4j.IbanUtil.validateBbanLength(IbanUtil.java:362) at org.iban4j.IbanUtil.validate(IbanUtil.java:79) at org.iban4j.Iban$Builder.build(Iban.java:365) at org.iban4j.Iban$Builder.build(Iban.java:337)

Although your accountNumber parameter is likely correct, this library expects 16 digits, i.e. the 10-digit account number appended to the 6-digit code as shown in the IBAN registry. Unfortunately, the IBAN registry does not indicate what those six digits are, although the "Domestic account number example" gives some indication (19 with pre-filled zeros).

This issue is resolved as of version "3.2.5-RELEASE" by using setPadding(true) on the builder method:

new Iban.Builder()
        .leftPadding(true)
        .countryCode(CountryCode.CZ)
        .bankCode("2010")
        .accountNumber("2300121591")
        .build()
        .toString();
