SWIFT Code stands for 'Society for Worldwide Interbank Financial Telecommunication' code. A SWIFT code is also called BIC Code 'Bank Identification Code' which is used to identify banks uniquely throughout the world. A SWIFT code is recognized and approved by the International Standards Organization, or ISO, and represents a particular bank or bank branch. It is especially useful in facilitating international wire transfers.
The SWIFT code is an 8 or 11 alphanumeric characters code that uniquely identifies financial institution. If a SWIFT code is eleven characters, this means that the bank has added a three-digit code to denote a specific branch of a bank.
First 4 characters - Bank Code - Identifies financial institution uniquely (only letters)
Next 2 characters - Country Code (only letters)
Next 2 characters - Location Code (Letters and Digits)
Optional Last 3 characters - Branch Code of a bank ('XXX' for main office) (Letters and Digits)
For e.g. the swift code for (RBC DEXIA PLATFORM CLIENT) branch of RBC DEXIA INVESTOR SERVICES TRUST is ROYCAUSGPWF where first 4 characters ROYC signify the bank code for RBC DEXIA INVESTOR SERVICES TRUST while last 3 characters PWF is the branch code for (RBC DEXIA PLATFORM CLIENT) branch. The above mentioned format of Bank Identifier Codes (BIC) or Swift Code is approved by the International Standard Organization (ISO) and represents a particular bank or bank branch.
