What is the swift code?

The SWIFT Bank Identification Code is an internationally-documented system of codes for identifying banks (see ISO 9362). Swift codes are commonly used to identify the banks included in an international wire transfer. It is not the only coding system for banks - individual countries also have their own sets of codes which are applied to identify banks in national interbank business. For example, ABA numbers (or routing codes) identify banks in the US and Canada, Sort Codes identify banks in the UK.
