Excellent addressing and accurate street data has the power to
transform people’s lives. In Great Britain, GeoPlace LLP is the
guardian and champion of that information on a national scale.

We act as a co-ordinator, supporting the nation’s street and
addressing data creators, making that information widely
available through Ordnance Survey and our statutory partners.

Working together with our partners, we maintain one of the
nation’s largest, most valuable shared assets – standardised
address and street indexes that are trusted by the whole of the
public sector, the private sector and beyond.

At the heart of those two indexes (the National Address Gazetteer
and the National Street Gazetteer), data users find two powerful
data identifiers: Unique Property Reference Numbers (UPRNs)
and Unique Street Reference Numbers (USRNs). These enable
many different data sources to be connected with ease and with
confidence. There is no duplication. No ambiguity. Accuracy is
our watchword. The use of this data leads to lower risks and costs;
higher productivity and profitability, and it brings down many of
the practical barriers to transformation and innovation across
both the public and private sector.

Without exception, Britain runs more efficiently and effectively
when service providers use UPRNs and USRNs – from next-day
deliveries of online shopping, to planning street works, collecting
meter readings, or directing the emergency services to the
right address in a high-rise block of flats. Our data keeps Britain
running smoothly. We are bringing location to life.
