Open Identifiers policy

Our Open Identifiers (ID) policy makes it easier for third parties to share information and link datasets. It is published as part of our OS Open MasterMap Implementation Programme, delivering some of our obligations under the Public Sector Geospatial Agreement (PSGA) between OS and the Geospatial Commission, part of the Department of Science, Innovation and Technology.

The policy is available in full on our website under Open Identifiers (ID) policy covering both our open products and services and premium products and services.
