A SWIFT code (also known as BIC Code) is a standard format to uniquely identify all banks and financial institutions across the world. The SWIFT code is a standard format for BIC - Business Identifier Codes.
If you transmit money across international lines you nearly always need to use a SWIFT code, as it’s the way banks and money transfer services figure out where the money needs to go. You can think of a BIC code a bit like a ZIP/postal code. A bank on one side of the world finds the right bank on the other side of the world. Like sending post to an incorrect ZIP code means it may go missing, the same goes for your money and an incorrect SWIFT code.
A BIC/SWIFT code is either 8 or 11 characters in length:
AAAA BB CC DDD
There are 2 types of SWIFT code: live and passive. Live codes are for financial institutions who are connected to the SWIFT network while passive Codes are used for manual transactions. Passive SWIFT codes will have a 1 as the second digit of the 2 character location code.
SWIFT code registrations and management are the responsibility of "Society for Worldwide Interbank Financial Telecommunication" (“SWIFT”) which is located in La Hulpe, Belgium.
