UK postcodes are alphanumeric codes used to identify specific locations for mail delivery. They consist of two main parts: the outward code (e.g., SW1A) and the inward code (e.g., 1AA). The outward code defines the postal area and district, while the inward code pinpoints a precise address or group of addresses. This system helps the Royal Mail efficiently sort and deliver mail.
