What is an outcode?

An outcode is part of a postal address used primarily in the United Kingdom, consisting of a series of letters and numbers that identify a specific area or locality. It typically precedes the inward code (the second part of the postcode) and helps in sorting and delivering mail more efficiently. For example, in the postcode "SW1A 1AA," "SW1A" is the outcode, indicating the area within London. Outcodes are essential for navigation and location identification in urban planning and service delivery.
