National address
gazetteer

What is the national address gazetteer?
The definitive database of addresses
For Great Britain
– bringing together the best of Local
Government and Ordnance Survey
address processes and products…..
– through a new joint venture company
called GeoPlace
The joint venture has agreed terms to
acquire Intelligent Addressing
– carrying forward the investment made
in the NLPG
– retaining existing Local Government
address and street processes
– OfT process
Harmonising processes
– local government and Ordnance Survey will manage a single address and street database
– this will be made available through Ordnance Survey to all PSMA members and the wider
commercial market
– Data reconciliation is underway
GeoPlace will manage the National Street Gazetteer
– and will bring together street products and processes from the partners in time.

Why are we doing this?
There have been three separate databases of addresses:
• Local Government’s National Land and Property Gazetteer (NLPG/NSG)
• Royal Mail’s Postcode Address File (PAF)
• Ordnance Survey’s OS MasterMap Address Layer 2 (Address Layer and ADDRESS-POINT)
Two separate databases of streets
• NSG
• ITN
Issues relating to:
• completeness
• currency
• each created against different standards
• all based on different references

harmonised solution

Benefits
Potential savings and opportunity
benefits across the public sector
from joining information for
service delivery and
policy development and monitoring.
Removal of direct costs for central gazetteer
services
The NAG will include
- the UPRN and USRN from local government,
- TOID references from Ordnance Survey,
- Royal Mail references and addresses and
- VOA references
which will facilitate data sharing between
organisational departments and all address
users.
