IBAN Calculator NL is a free Android app developed by ENVINE B.V. that helps you calculate the International Bank Account Number (IBAN) of Dutch bank accounts. As part of the Single Euro Payments Area (SEPA), many countries - including the Netherlands - are replacing their current bank account numbers with IBANs. This app uses the bank and Dutch bank account number to determine the corresponding IBAN, and also checks the entered account numbers using the 11-proof, except for old Postbank numbers. Additionally, it displays the Bank Identifier Code (BIC) of the selected bank, which is still required for cross-border payments. Please note that the developer is not liable for any inaccuracies or misuse of the information provided by this app.
