Sort Code is used for domestic bank transfers in England and Ireland only, whereas Swift Code is used for international bank transfers worldwide. Sort Code can be used as a transfer for location within the country or city. Swift Code is for the safety of money and transactions internationally.
Sort Code has six unique characters, and Swift Code is anywhere between 8 to 11 characters depending on the location or country. Swift Code has both numbers and alphabets, but Sort Code has only numbers that differentiate both codes.
In Swift Code, the characters are divided into four different divisions, but this is not the case with Sort Code.
