What We Do.

Welcome to Open Address File UK

Campaigning for an open address file for the UK

Like most countries, the UK has ‘address data’ – an official list of all the postal addresses in the country and where they are. This data is important for helping people get post, for government services, and for businesses.

Unlike most countries, in the UK, our address data is not maintained by the government and free. Instead, it’s owned and managed by private companies and public sector bodies, in a complex and costly tangle of intellectual property rights and contracts. 

As a result, the UK’s address data is difficult to correct, and expensive to use. This makes life harder for people and businesses.

We want to fix that.

Have you been affected by poor address data? It’s important that your story is heard so that we can all  make address data better.

Who We Are.

A coalition of the willing
