Please help,
I am trying to enter my bank account details (PKO Bank In Poland) but always get the error: "The IBAN number is invalid." I'm using account in PLN zl.
account number: 52########0000########1123 (26 symbols) IBAN: PL52 ########0000########1123 (28 symbols)
I've tryed other accounts, and I'm sure all of them are correct (information was given from the bank page and validated by IBAN checker services), but error blocks me.
How to resolve this issue? Thanks.
