What AddressBase Core provides you with

Approved addressing records

AddressBase Core provides approved addressing records for England, Wales and Scotland based on Local Authority holdings of the National Land and Property Gazetteer (NLPG) and One Scotland Address Gazetteer (OSG). Other attribution includes property level coordinates and secondary level classifications (detailing the use and type of an address).

Property classification

Through property classification attributes, you can quickly understand, locate and perform analysis on the type of addresses you want to interact with.

Authoritative data

AddressBase Core's primary source of addressing information is local authority data. They have the legal responsibility to capture and maintain address data for Great Britain, so you can be sure of its authenticity and legal nature.

Weekly updates

AddressBase Core is released weekly, keeping you more up to date with change.

Additional information

Advantage of AddressBase Core over other AddressBase products

AddressBase Core takes many of the high importance items from the other AddressBase products, such as coordinates, classifications (type of address) and links to other important identifiers; but it also includes a single attribute for an address line, is updated weekly, and is offered in an easier to digest format to make the product as easy to access and use as possible.

Properties yet to be built or have been demolished

Properties yet to be built, or those which have been demolished, do not appear in AddressBase Core. In order to keep AddressBase Core as simple as possible, these records are not present. If these are critical to you, please look at AddressBase Premium.

AddressBase Core epoch correspondence

AddressBase Core is released weekly and has a different data extraction date compared to the 6-weekly release schedule of the other AddressBase products. Due to these differences AddressBase Core will not correspond to any of the epochs.

Coverage of AddressBase Core

AddressBase Core covers Great Britain only. This is England, Wales and Scotland. It does not include Northern Ireland and the Channel Islands.

Data from Royal Mail’s PAF

The database is a vital component of the single address gazetteer database and is in each of the AddressBase products where there has been a match confirming the address to the LLPG address.
