Air and SeaPort Codes
Airport and seaport codes are used to identify the place of clearance for UK imports and exports with countries outside the European Union (non-EU). They are not used within the Intrastat system (import and export trade with countries in the European Union).
Users of the Data Downloads pages may also be interested in the Location code list
which is used to identify Inland Clearance Depots, Freezones and National Export System (NES) Local Clearance Freight Locations.
