"This report describes how public money can be saved and services to citizens improved by increasing the sharing of basic citizen contact details (such as name and address, date of birth, etc), across central and local Government. Although some parts of the public sector are rationalising the information held on internal systems, it remains the case that there are many different public sector organisations attempting to maintain local citizen contact details. We have been able to identify at least five sets of contact details held separately. Improved data sharing across the public sector would reduce the administrative burden to both departments and the citizen of maintaining basic contact information, and would assist in delivery of the e-government commitment that the citizen should be able to inform the entire public sector of change of circumstances through a single electronic interaction.
