Where does Address data come from?
Background
Since 2011, addressing information has been managed by GeoPlace LLPG under a joint venture partnership between Local Government Association and Ordnance Survey (OS).
GeoPlace has a central hub that collates and processes large volumes of data on a daily basis from over 350 data source providers including:
Local Authorities
Local Authorities have custodians that manage their Local Land and Property Gazetteer (LLPG) and the Local Highways Authority create and manage their Local Street Gazetteer (LSG)

Royal Mail
Royal Mail create and manage their own Postcode Address Database, that holds and individual Postcode Address File (PAF) for each Delivery Point Address (DPA)

Valuation Office Agency
The Valuation Office Agency (VOA) holds data on properties that are non-domestic/business claiming business rate taxes, this data is matched with the property's address from the National Land and Property Gazetteer (NLPG)

Improvement Service
The Improvement Service manage the One Scotland Gazetteer (OSG) which is updated by 32 Scottish Authorities

Ordnance Survey
Ordnance Survey provides OS MasterMap Topography Layer, OS MasterMap Highways Layer data locates additional non-postal addresses
Once GeoPlace has received the LLPG data and the LSG data maintained by local authorities, they can compile the National Land and Property Gazetteer (NLPG), National Street Gazetteer (NSG), and One Scotland Gazetteer (OSG).
They also enrich the data using various data sets to populate product attributes including improving the coordinates, classifications, and lifecycle information to enhance the overall quality of the data.

Once all data submissions have been extracted, transformed, validated, and loaded, everything is brought together to produce the National Address Gazetteer, the single definitive source of accurate addressing and street data for the UK.
Data from the National Address Gazetteer is transformed into AdressBase products for Ordnance Survey to publish to the Public Sector and Partners.
Lifecycle
The addressing information is used to verify the chronological timeline of the lifecycle of every single property in the UK.
