We are not responsible for issuing new postcodes. New postcodes are issued by Royal Mail - however they will not issue a postcode for a new street unless requested to do so by us.
Queries about postcodes can be dealt with by the Royal Mail by contacting them on their Customer Services line or by visiting the Royal Mail website.
Postcodes for commercial premises are allocated in the same way as for residential premises, but a large company can apply to the Royal Mail for its own code (known as a large user code). Applications for large user codes is the responsibility of the company concerned as they will know what volume of mail they generate.
