There are approximately 5 million people on probation, parole and other types of community supervision in the United States. A subset, about 250,000 every year, are on supervision after a conviction of a federal offense. The United States Probation System is required to make state and local law enforcement agencies aware when certain federal offenders* reside in your jurisdiction. The information provided here within LENS does not include offenders convicted in state or local jurisdictions nor does it include federal offenders convicted of non-qualifying offenses. The information you are provided here is in addition to information reported within NCIC and other systems.

Contact the United States Probation Office within your jurisdiction for more information or to share information about offenders included in LENS.




The Law Enforcement Notification System (LENS) is available to state and local law enforcement agencies pursuant to provisions of section 20417 of the Violent Crime Control and Law Enforcement Act of 1994 (Pub. L. No. 103-322, 108 Stat. 1796, 1834, Sept. 13, 1994) (codified at 18 U.S.C. §§ 4042(b) and (c)), which requires notification to state and local law enforcement agencies when qualifying offenders move to a new jurisdiction.

* Qualifying offenders include those convicted of certain drug trafficking crimes described under Title 18 U.S.C. § 924(c)(2), crimes of violence described under Title 18 U.S.C. § 924(c)(3), sex offenses and those convicted of internet child pornography offenses included as part of The Sex Offender Registration and Notification Act (Title I of Pub. L. No. 109-248, 120 Stat. 590, July 27, 2006).

This system is available 24 hours, 7 days a week. However, call-in support from your local US Probation Office is only available Monday through Friday during normal business hours.
