Using household counts from the Royal Mail postcode address file (PAF), we have developed our delivery rounds based on Postcode Districts – these are the first half of a Postcode, i.e., AL5 or SA1. We take the Postcode districts of the areas we operate in and break them down into D2D Distribution Zones – each distribution Zone is on average 750 homes or individual letterboxes. So with DOR-2-DOR it is very easy to target your preferred households. The Distribution Zones are available in map form, showing each delivery round and the number of households. These maps are available to download from the DOR-2-DOR website under the relevant postcode district which can be found on the Areas Covered page. Each office will be able to supply socio-demographic information about each round and the likely impact of the customer’s product or service in that area. To choose your preferred Distribution Zones, simply ask for the DOR-2-DOR Distribution Round Map covering your preferred location or click here to go to our AREAS page.
