# AddressBase Core Getting Started Guide

AddressBase Core is an easy-to-use, accessible addressing data product that gives plug-and-play access to complete and accurate address data. It combines key elements from existing AddressBase products into a simplified product.

{% hint style="info" %}
AddressBase Core's primary source of addressing information is Local Authorities who have the statutory responsibility to capture and maintain Great Britain's address data. This ensures that the data is both authentic and authoritative in nature. Records are supplemented with Royal Mail Postal Address File (PAF) information and additional Ordnance Survey information on the usage of the address and unique identifiers that allow links to other OS and third-party datasets. Please read Data sources in AddressBase general for further details.
{% endhint %}

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.os.uk/os-downloads/products/addresses-and-names-portfolio/addressbase-core/addressbase-core-getting-started-guide.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
