This code list is used in association with the Postcode Type attribute and describes the postcode as a small or large user as defined by Royal Mail.
For more information about the postcode type, please consult chapter one 'Structure of a PAF address' of the Royal Mail Programmer's Guide.

Definition
Large User
These are assigned to one single address either due to the large volume of mail received at that address, or because a PO Box or Selectapost service has been set up. Large Users receive a minimum of over 1 000 items of mail a day.
Small User
These identify a group of delivery points. On average there are 15 delivery points per postcode. However, this can vary between 1 and, in some cases, 100. There will never be more than 100 delivery points on a postcode.
