OS GB Address
OS GB Address is Ordnance Survey’s new, definitive address dataset for Great Britain – it’s the natural successor to AddressBase Premium.
OS GB Address brings together authoritative local authority address data, Royal Mail postal addresses, Unique Property Reference Numbers and rich property lifecycle information in one powerful dataset.
As part of the OS National Geographic Database, OS GB Address gives organisations a more complete and reliable way to understand properties, addresses and the built environment. It should help users move from traditional address data into a more flexible, analysis-ready dataset built for modern GIS, operational and data-management workflows.
OS GB Address is available through Emapsite Mapshop as a downloadable CSV or GeoPackage. It is also available as a Managed Service for organisations that need a more supported, streamlined way to access and maintain address data – we’re here to help you migrate and maintain.
In fact, we recommend migrating to the improved datasets as soon as possible, to ensure continuity. For migration assistance or questions, do get in touch.

What can OS GB Address do for me?
OS GB Address helps you turn addresses into usable location intelligence.
The dataset includes more than 41 million address records for Great Britain, combining local authority address data with 100% of Royal Mail’s Postcode Address File. It also includes precise coordinates, UPRNs, Royal Mail Unique Delivery Point Reference Numbers and detailed address classification.
This means you can do far more than find an address. You can understand what type of property you’re looking at, where it is, whether it is in development, whether it has changed, and how it connects to other location datasets. OS GB Address is a valuable asset for organisations that need to match, clean, analyse, enrich or manage address records at scale.
