A new open address list, that will be available for everyone to use without restriction, has been launched by Open Address UK. The address list, which has been wholly funded by the Cabinet Office,  aims to create a single national resource for address data and currently holds around one million addresses. Open Address UK is inviting individuals and organisations to collaborate in developing and maintaining the address list by submitting data. The Open Address UK website allows users to submit single or multiple datasets as well as download address data.
