What is the National Crime Information Center?

The National Crime Information Center (NCIC) is the United States’ central database that is used for tracking crime-related information. Since 1967, the National Crime Information Center has been maintained by the Federal Bureau of Investigation (FBI) Criminal Justice Information Services Division, and is interlinked with similar systems that are maintained by each state in the country.

The original purpose of the NCIC system was to create a centralized information system to facilitate the flow of information and crime data between the numerous law enforcement branches in the federal government. It is widely considered to be the lifeline of police and law enforcement that is used by every criminal justice agency in the country around the clock.

National Crime Information Center (NCIC) Records

The NCIC makes available a variety of records to be used for law enforcement and security purposes. These criminal records are made up of a variety of forms of personal and property records.

What Types of Data Does the National Crime Information Center Contain?

The NCIC stores data and statistics on crime that is received from federal, state and local law enforcement agencies, as well lesser known law enforcement agencies such as tribal law police forces, railroad police, and non-law enforcement agencies, such as state and federal motor vehicle registration and licensing authorities.

The NCIC database currently consists of 21 files: There are seven property files containing records of stolen articles, boats, guns, license plates, parts, securities, and vehicles. There are 14 persons files, including: Supervised Release; National Sex Offender Registry; Foreign Fugitive; Immigration Violator; Missing Person; Protection Order; Unidentified Person; Protective Interest; Gang; Known or Appropriately Suspected Terrorist; Wanted Person; Identity Theft; Violent Person; and National Instant Criminal Background Check System (NICS) Denied Transaction.

The system also contains images that can be associated with NCIC records to help agencies identify people and property items. The Interstate Identification Index, which contains automated criminal history record information, is accessible through the same network. The NCIC database includes 21 files (seven property files and 14 person files). Following is a brief description of each:

Violent Person File: Once fully populated with data from our users, this file will contain records of persons with a violent criminal history and persons who have previously threatened law enforcement.

How is the National Crime Information Center Used by Law Enforcement Agencies?

Criminal justice agencies enter records into NCIC that are accessible to law enforcement agencies nationwide. For example, a law enforcement officer can search NCIC during a traffic stop to determine if the vehicle in question is stolen or if the driver is wanted by law enforcement. The system responds instantly. However, a positive response from NCIC is not probable cause for an officer to take action. NCIC policy requires the inquiring agency to make contact with the entering agency to verify the information is accurate and up-to-date. Once the record is confirmed, the inquiring agency may take action to arrest a fugitive, return a missing person, charge a subject with violation of a protection order, or recover stolen property.
