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.
