# AddressBase Plus

{% embed url="<https://www.ordnancesurvey.co.uk/products/addressbase-plus>" %}

AddressBase Plus contains current properties using addresses sourced from Local Authorities, Ordnance Survey and Royal Mail for England, Wales and Scotland. The product currently contains approximately 37 million records.

The product contains all current addresses validated from Local Custodians and non-postal addresses such as ponds, electricity sub-stations and telephone boxes are also included.

The product enables the end-user to locate an address or property on a map using either X, Y coordinates supplied on a British National Grid or Latitude and Longitude coordinates provided on an ETRS89 projection, and display the Local Authority address elements or the Royal Mail address elements where matched.

{% tab title="Features" %}

#### **Flat file model**

AddressBase Plus is structured in a flat file model – containing current properties and addresses sourced from local authorities, Ordnance Survey and Royal Mail matched to the UPRN.

#### **Accuracy guaranteed**

The address information is sourced from 380 local authorities across Great Britain, our own large-scale mapping, Royal Mail and the Valuation Office Agency.

#### **Useful addresses**

As well as 28 million defined properties, Ordnance Survey have included more than 7 million local authority addresses, such as depots and church halls, places of worship and community centres.

#### **Property classification**

Understanding the need to categorise properties, Ordnance Survey incorporated a four-level classification scheme that explains the function of each property.

{% tab title="Use Cases" %}

#### **Individual address referencing for direct marketing teams**

Take your data analysis to the next level by referencing data to individual addresses (such as flats) rather than mail delivery points (houses divided into flats).

#### **Property classification**

Understanding the need to categorise properties, Ordnance Survey incorporated a four-level classification scheme that explains the function of each property.

{% tab title="Additional Information" %}

#### **Advantage of AddressBase Plus over AddressBase**

AddressBase contains Royal Mail PAF addresses and assigns an x and y coordinate to every address. This lets you carry out only relatively basic analysis.

AddressBase Plus also includes current properties and addresses sourced from local authorities, Ordnance Survey and Royal Mail. Records are matched to the UPRN and structured in a flat-file model.

AddressBase Plus holds more records than AddressBase as it includes objects without postal addresses, such as subdivided properties, places of worship and community centres. It also allows the end-user to locate an address or property on a map, through the assigned x and y coordinates.

Crucially, cross-referencing the information with OS MasterMap products via the OS MasterMap Topography Layer and Topographic Identifiers (TOIDs) lets you view address data within a wider geographic context.

#### **Properties yet to be built**

Properties yet to be built do not appear in AddressBase Plus. You'd need AddressBase Premium for this information. It's ideal when you're planning the future provision of infrastructure services such as sewerage or high-speed broadband.

#### **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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.os.uk/os-downloads/~/changes/AJZwzCsyrD9hiTbOxIbO/addressing-and-location/addressbase-plus.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
