The Government currently holds five databases containing electronic DNA profile information. Details below reflect the position as it stood on 30 September 2013.

The national DNA database (NDNAD) holds DNA profiles taken from individuals and crime scenes. It is used for purposes related to the prevention or detection of crime, the investigation of an offence or the conduct of a prosecution; in the interests of national security; for the purposes of a terrorist investigation; and for purposes related to the identification of a deceased person or of the person to whom material relates. It was set up in April 1995 and currently holds 6,074,866 DNA profiles.

The missing persons DNA database holds DNA profiles obtained from the belongings of people who have gone missing, or from their close relatives (who will have similar DNA), as well as profiles taken from the bodies of unidentified people. It matches missing people (sometimes via their relatives) to unidentified bodies, and can also eliminate a missing person if an unidentified body is found matching their description. It was set up in April 2010 and currently holds 895 DNA profiles.

The vulnerable persons DNA database holds DNA profiles of people who are at risk of harm (for instance due to child sexual exploitation or honour-based violence) and who have asked for their profile to be added. If the person subsequently goes missing, their profile can be checked against the main NDNAD to see if they match to any material such as blood or an unidentified body found at a crime scene, helping the police to investigate their disappearance. It was set up in March 2011 and currently holds 1,967 DNA profiles.

The police elimination database holds DNA profiles for police officers and staff. These profiles are used for elimination purposes in criminal casework. It was set up in August 2000 and currently holds 127,100 profiles.

These four databases are run by the Home Office, having been transferred from the National Policing Improvement Agency (NPIA) on its closure.

The counter-terrorism (CT) DNA database holds profiles retained specifically for the purposes of national security. It was established in July 2006 and is managed and maintained by the Metropolitan Police Service (MPS) on behalf of UK CT policing. Due to the sensitive nature of the CT DNA database it is not possible to confirm the number of profiles held.
