Product information
What is Not Yet Built™?
Whenever a new residential or commercial property receives planning permission, the local authority will assign a house name and a street name before coming to Royal Mail to ask us to assign a postcode. Royal Mail captures all of these address and postcode details on our Not Yet Built™ database.
Who uses Not Yet Built™?
The Not Yet Built™ database gives you details of properties that are being built or are scheduled to be built in the future. This data will be especially beneficial if you are involved in property and construction. Whether you are a developer, builder, materials supplier, utility company, landscape gardener or financial services provider offering mortgage and credit cards, you’ll find Not Yet Built™ a valuable marketing asset.
Not Yet Built™ Data
Not Yet Built™ holds approximately 250,000 – 300,000 records, though the amount depends entirely on the number of properties currently under construction or in the planning phase. Records are held until they have finished being built and are capable of receiving mail, at which point it will be transferred to Just Built™ and PAF®. If a proposed development is abandoned or stopped then it will be removed from the file.
Not Yet Built™ includes data for England, Scotland, Wales and Northern Ireland but excludes Jersey, Guernsey and the Isle of Man.
File formats
Not Yet Built™ is available in three file formats:
Not Yet Built™ Keyed – a relational style database that must be used in conjunction with the PAF® Mainfile
Not Yet Built™ Expanded – a text file that gives one record for each range of delivery points listed e.g. 1-20 High Street will be shown as 20 separate records
Not Yet Built™ Ranges – a text file that gives one record for each range of delivery points, e.g. 1-20 High Street will be shown as one record.
Not Yet Built™ data is refreshed monthly.
Technical Information
When a delivery point is added to Not Yet Built™ we assign it a Unique Delivery Point Reference Number (UDPRN) and a Delivery Point Suffix (DPS). This information helps us to maintain important links between this database and PAF® (Postcode Address File)
