@New-Ivory-Woodchuck-1315270257#242152 Nowadays it's technically not needed to give any other information that the IBAN, so I would make sure with the sender/other person that this information is really necessary. If it's a bank, they should also have no issue extracting this information by themselves just from the IBAN.

But here's how to do it yourself if it's really necessary:

• BIC: Use the one that is displayed when tapping on the IBAN or reference this topic.
• How to extract account number or branch code depends on the country of your IBAN:
  • For NL IBANs: account number is the last 10 digits of the IBAN. Bank code is BUNQ. No branch codes.
  • For DE IBANs: account number is the last 10 digits of the IBAN. Bank code is 37019000. No branch codes.
  • For FR IBANs: Bank code is digit 5 to 9. Branch code is digit 10 to 14. Account number is digit 15 to 25. (Note: don't use last two digits of the IBAN).
  • For ES IBANs: Bank code is digit 5 to 8. Branch code is digit 9 to 12. Account number is digit 15 to 24. (Note: don't use digits 13 and 14.)

P.S. The initialism IBAN stands for International Bank Account Number. It's internationally unique and identifies your bank account.
