About this calculator

UK postcodes follow a structured format — an outward code (like SW1A or M1) identifying the postcode area and district, and an inward code (like 1AA) narrowing it to a specific street or building group. This lookup matches a full postcode or just the outward code to its place name, county or unitary authority, and region, based on Royal Mail's postcode geography.

Because outward codes alone map to a town or district (SW1A = Westminster, London; M1 = Manchester city centre), the lookup also works for quick "which city is this postcode in" checks without needing the full address.

E-commerce and logistics teams validating shipping addresses, customer service reps confirming a caller's location, UK-based sales and marketing analysts segmenting by region, and anyone receiving an unfamiliar postcode who wants to know where it actually is all use this tool.
