Postal codes or ZIP codes are unique identity numbers for indicating a particular region. Every country has a general postal format, while every state/county/region in the country has specific postal code numbers/letters. In the UK, the postal code format is a bit different – instead of being a series of five to nine numbers, it is a series of three to five alphanumeric codes.
Apparently, no two counties have the same postal code (called postcodes). If you just moved into the UK, or need a parcel delivered to someone in the UK, you just need to know the postcode (ZIP code) of the particular UK county the delivery would be sent. Interestingly, this article lists the postal codes of all UK counties and regions.
United Kingdom ZIP Codes: Full List Of UK Postal Codes by States
The UK postcodes are different from the US ZIP codes, but they serve the same purpose. UK postcodes comprise “Outward” and “Inward” codes, where the outward code comes first (usually letters) and then the district and inward codes.
