On April 18, 2006 it was announced that instead of continuing as a separate project, it would be integrated into the National Identity Register, the database behind the proposed national identity cards. It has been estimated that this might add £200 million to the cost of the identity cards
In late 2003 the project moved into a definition phase. It was hoped that the CIP would be able to use data from the proposed National Identity Register.
A report on preliminary testing was due in April 2005, and it had been expected that it would have been implemented before the end of 2007 if approval had been given by Government. Initial estimates in 2004 suggested that the costs might have been £1.2 - £2.4 billion (240 million annually for a period of 5 to 10 years).

The Citizen Information Project won the Office for National Statistics the 2004 Big Brother Award for the "Most Heinous Government Organisation" from the campaigning organisation Privacy International.
