IBAN conversion/validation/search

Calculate an IBAN: Determine the international bank account number (IBAN) based on the sort code (bank code) and account number or national equivalent. For some countries, the BIC is shown as well.
Check an IBAN: For some countries, we check not just the IBAN checksum, but also the validity of the bank code and account numbers that are contained in the IBAN.
Check account number: Check whether the checksum inside an account number is correct.
Find bank/bank code/BIC: You can either enter the bank name and city to determine the bank code (or sort code) and BIC, or you can enter the sort code and find out the bank name, city, and BIC.
