NWBK

NWBK is the four-letter bank code used in the SWIFT financial messaging system for National Westminster Bank, commonly known as NatWest. In SWIFT messaging, the Bank Identifier Code (BIC) begins with NWBK to designate NatWest as the sending or receiving financial institution. A complete SWIFT code for NatWest typically starts with NWBK and is followed by country, location, and branch identifiers, enabling the routing of international payments to NatWest branches and accounts. The NWBK prefix thus functions as the bank code component of NatWest’s international payment identifiers.

National Westminster Bank plc, trading as NatWest, is a major retail and commercial bank in the United Kingdom. It operates as the consumer and business banking arm of NatWest Group, a British financial services holding company. NatWest traces its modern form to the 1968 merger of Westminster Bank and National Provincial Bank; it later became part of the Royal Bank of Scotland group and, in its current structure, is part of NatWest Group.

NatWest Group is the parent company of NatWest and other brands, providing a range of banking and financial services in the UK, including personal banking, business banking, and wealth management. As a widely used identifier in international settlements, NWBK is primarily recognized as the NatWest bank code within the SWIFT network rather than as a standalone corporate acronym.
