UK Sort Code to IBAN
Convert a UK sort code and account number to the correct 22-character IBAN. Required when receiving international transfers or using cross-border payment services.
Note about the bank code: A UK IBAN encodes a 4-letter bank identifier (the first 4 characters of the bank's BIC). For example, NatWest = NWBK, Barclays = BARC, HSBC = HSBC, Lloyds = LLOY, Halifax = HBOS, Monzo = MONZ, Wise = TRWI. If you don't know yours, leave it blank to see the IBAN structure (it will show XXXX as a placeholder).
Hyphens are stripped automatically. Enter as 200000 or 20-00-00.
First 4 letters of your bank's BIC/SWIFT code. See note above for common codes.

Total length: 22 characters. UK domestic transfers still use sort code + account number. The IBAN is only needed for international transfers.
