We are not responsible for issuing new postcodes, this is the responsibility of Royal Mail.
You can search for postcodes on the Royal Mail website. Go to Royal Mail: find an address.
New postcodes
Royal Mail will not issue a postcode for a new street or property unless we ask them to do so.
Customised postcodes for large businesses
Postcodes for commercial premises are allocated in the same way as residential premises.
A large company or business can apply to the Royal Mail for its own customised postcode.
