The government plans to create a single address list for use across the public sector in a move that could significantly reduce data duplication.
GeoPlace will be launched as a joint venture between local government and Ordnance Survey (OS). The system is intended to eliminate the duplication of address records across the public sector.
The OS and local government will acquire property database company, the National Land and Property Gazetteer.
Communities secretary Eric Pickles said the move will provide the government with a list of accurate spatial address data and save money on unnecessary data licensing.
"It is vital that the emergency services can get to people as quickly as possible. Having only one address book will make that job easier, deliver vital savings that can be put towards frontline services and bring real benefits for business," he said.
Information on the database will be made available free at the point of use for all public sector bodies under the centrally funded public sector mapping agreement.
Baroness Margaret Eaton, chairman of the Local Government Group, said: "This landmark agreement will allow councils and other public sector organisations to build a better, more accurate picture of where people live to help them deliver the services people need in a way that they want."
The deal is subject to approval from the Office of Fair Trading.
The previous government had made attempts at creating a single shared database. The last was the National Spatial Address Infrastructure, which was shelved in 2005 due to intellectual property disagreements.
