What is the Police National Computer (PNC)?
At its core, the PNC is the principal database used by the police in the UK. It's not a single, monolithic database, but rather an amalgamation of several interconnected databases, each holding specific types of information relevant to policing. Think of it as a highly sophisticated digital filing system that consolidates critical data points, allowing for rapid retrieval and cross-referencing. While fingerprints and DNA profiles themselves are not stored directly on the PNC, it crucially holds reference links to these vital biometric datasets, which are managed by the National Fingerprint Database (IDENT1) and the National DNA Database (NDNAD) respectively. This linking mechanism is essential for connecting individuals to physical evidence.
PNC vs. PND: A Key Distinction
It's important to distinguish the PNC from the Police National Database (PND). While both are police databases, they serve different purposes. The PND is designed to store "soft" intelligence – information gathered from local police force investigations that may not have resulted in a conviction. This can include details about ongoing criminal investigations, suspicious activity, and other intelligence that doesn't fit neatly into the structured data of the PNC. The PNC, on the other hand, is primarily focused on structured, verifiable data directly relevant to law enforcement actions and legal processes.
Data Held Within the PNC
The PNC is a treasure trove of information, meticulously organised to support police work. Its contents can be broadly categorised as follows:
Names Files
These files are central to identifying and tracking individuals. Information held within Names files pertains to people who are, or have been, of interest to UK law enforcement agencies. This includes individuals who:
- Have past convictions or cautions for criminal offences, including youth warnings and reprimands.
- Are currently subject to the legal process, such as awaiting court appearances.
- Are officially listed as wanted by the police.
- Are subject to specific court orders.
- Are recorded as missing or have been found.
- Have absconded from specified institutions.
- Have been disqualified from driving by a court.
- Possess a driver record held by the Driver and Vehicle Licensing Agency (DVLA).
- Hold a firearm certificate.
Vehicle Files
The PNC contains extensive vehicle records, drawing information directly from the DVLA. This includes details on vehicle ownership, tax records, and other pertinent vehicle data. Crucially, crime reports can also be attached to these vehicle records, allowing officers to link vehicles to criminal activity. This is invaluable for investigations involving stolen vehicles or vehicles used in the commission of crimes.
Property Files
Certain types of stolen property can be listed on the PNC. This allows officers to identify and recover stolen goods, aiding in the disruption of criminal enterprises and the return of property to its rightful owners.
Driver Files
Complementing the vehicle files, the driver files contain information directly from driving licence records, providing a comprehensive view of an individual's driving history and licensing status.
PNC Capabilities and International Links
The PNC is not just a static repository of information; it's a dynamic tool that facilitates real-time checks on people, vehicles, crimes, and property. Its utility is further amplified by its integration with international systems. Notably, the PNC links with the Schengen Information System (SIS II), a large-scale IT system used by European countries. This connection enables participating member states to share real-time information on persons and objects of interest through a system of "Alerts." These SIS II alerts cover a range of critical situations, including:
- Persons wanted for extradition.
- Missing persons.
- Individuals wanted for judicial purposes.
- People or vehicles requiring discreet checks.
- Misappropriated, lost, or stolen objects sought for seizure or other legal purposes.
Furthermore, information held on the PNC can be shared with foreign nations under specific circumstances, as demonstrated by agreements for sharing information with the United States of America.

Who Has Access to the PNC?
Access to the PNC is strictly controlled and granted to a range of authorised bodies to ensure its integrity and effective use. This includes:
- All police forces and law enforcement agencies throughout England, Scotland, Wales, Northern Ireland, the Isle of Man, and the Channel Islands.
- A number of other government departments and agencies, such as the Disclosure and Barring Service (DBS), HM Prison Service, HMRC, the House of Commons, the House of Lords, the Home Office, and Royal Mail, for specific, legally defined purposes.
Anyone accessing the PNC must adhere to strict operating procedures. For detailed guidance, reference to the official PNC services is recommended.
Can I Check the PNC?
Direct access to the PNC for the general public is not permitted. However, individuals can request to check their own information held on the PNC. This can be done in relation to your own personal records or if you have obtained express authority from another individual (a third-party request) to access their information. Information on how to initiate such a check is available through official channels.
How Long Are Police Records Held on the PNC?
The retention periods for records on the PNC are substantial, reflecting the seriousness of the information they contain. For instance, if you have been issued with an arrest record, police caution, conditional caution, youth caution, youth conditional caution, reprimand, or final warning, these records are typically retained on the PNC until you reach the age of 100. In effect, this means many records are held for life.
Can You Delete Police Records off of the PNC?
It is possible to have certain records, such as cautions and other police disposals, deleted from the PNC. This is not an automatic process and requires individuals to provide good grounds for deletion. Successful applications typically demonstrate that a police caution was issued unlawfully, or that its continued presence is not in the public interest. Such applications often require legal expertise.
PNC Record Deletion Solicitors
If you have a police caution, an arrest record, or any other police disposal recorded on the PNC and are concerned about its potential impact on your life, seeking professional legal advice is highly recommended. Specialist solicitors have a proven track record in successfully applying for the expungement of police cautions and other police records from the PNC. If you face any police record or Disclosure and Barring Service (DBS) related issues, getting in touch for an initial consultation is a crucial first step.
Frequently Asked Questions
Q1: What is the main purpose of the PNC?
The main purpose of the PNC is to provide a central, real-time database for law enforcement agencies to access critical information on individuals, vehicles, crimes, and property, aiding in crime prevention, investigation, and public safety.

Q2: Can my fingerprints or DNA be found on the PNC?
No, your actual fingerprints or DNA profiles are not stored on the PNC. However, the PNC contains reference links to your fingerprint and DNA data held on separate national databases (IDENT1 and NDNAD).
Q3: Who is allowed to access the PNC?
Access is restricted to police forces, law enforcement agencies, and other approved government departments and organisations for specific, legally defined purposes. Public access is not permitted.
Q4: How long are records kept on the PNC?
