An introduction to AddressBase Core

The new Public Sector Geospatial Agreement (PSGA) is set to benefit the public sector, businesses, developers and academia. It will deliver the next generation of location data and transform the way people access, share and innovate with geospatial data, through new, richer data, improved access and ease of use and new freedoms to share information.

These new freedoms and the ability to link datasets for third parties included the announcement of the Open Unique Property Reference Number (UPRN) product, that will allow you to freely incorporate this key identifier into your data holdings. The OS Open UPRN product will provide a unique identifier for every location that can have an address along with a coordinate. But what do you do if you need to know the address, extra attribution and be able to rely on it as the authoritative source of information? This is where AddressBase Core can help.

AddressBase Core data extract

AddressBase Core is soon to become the newest member of the AddressBase product family, set for release in July. We’ve been working hard over the last 18 months to create an addressing product that is lightweight, easy to load, lower in cost and updated more frequently than before, in line with feedback during user engagement and testing of our current products.

To make the product simple and easy to use we are providing the core elements for an address gazetteer – identifiers, location, classification and address line elements for live records. We believe AddressBase Core is a great introductory product to cater for your addressing needs.

Although AddressBase Core has a simple to use data structure, it holds a wealth of information that opens it up to many use cases. Secondary level classifications (as shown in the image above) allow you to identify and filter properties at a greater granularity; for example you can find all the commercial leisure (CL) facilities within an area for specific mailshot campaigns, or you can use data analysis to find development land (LD) for utility network planning.


We had some great user feedback during our most recent trial, with respondents particularly liking the inclusion of a new attribute called the Single Line Address. This attribute contains all address elements required to produce an address which is aligned to what you would put on an envelope. This new attribute will be specifically beneficial for use cases such as address verification and ensures customers can simply plug AddressBase Core into their systems without the need to pre-process the data.

Other positive feedback included the new easy to use formats, which includes the introduction of GeoPackage. This made it really simple to load into a GIS and be able to visualise the geometry straight-away.

  1. I’ve just downloaded the first release of AddressBase Core for use by the City of Durham Parish Council, where I am a Parish Councillor. Some quick comments and a request:
    Single Line Address is a real plus and the main reason I downloaded the data. A nice-to-have would be mixed case, so it isn’t all in capitals, but I can fairly easily do a text transformation.
    But the file contains 33,036,685 records plus the header, which is too large to fit into my spreadsheet, so I had to write a program to extract everything with a DH1 postcode. So when the 5km squares come along that would be a big bonus.
    Would it be possible to add the WARD_CODE and PARISH_CODE fields as are in AddressBase Plus? As things stand I will have to refer to a different database table to find out which records are in our parish. The GSS_CODE of E06000047 relates to the unitary authority of County Durham and we need the granularity.

      Roger, you are correct that we plan to release ‘Areas of Interest’ functionality (where you don’t have to take all of GB and the circa 33 million rows in one file) later this year which will resolve one of your issues. Regarding your suggestion regarding Parish and Ward codes, currently we do not plan to include these cross references in our product. We have passed on your feedback to the relevant team who have said they will consider any enhancements or changes as the product develops and has been in market for a longer time period. Hope this helps, Jocelyn.
