Stolen Vehicle File Feed (Utilizing AM Message Key)

Overview

Mobile and fixed LPR systems read and recognize millions of license plates per day. Law enforcement has embraced this technology by employing LPR systems to assist in locating missing or endangered children, wanted felons, and stolen vehicles. They have also been used to tie specific vehicles to crime scene investigations and to report geographic boundary violations for sex offenders.

The efficiency of the LPR device and comparing the LPR "reads" is only as good as the data in the plate of interest file. The plate of interest file usually includes plates linked to warrants in the local jurisdiction, stolen vehicles, and vehicles linked to officer safety alerts. The most common method of populating the local plate of interest database is via a USB drive in the trunk of the LPR equipped police vehicle. Officers assigned to these vehicles will get a fresh copy of the file at the start of their shift. Vehicles stolen during their shift are not present on the USB drive. It is widely acknowledged that stale stolen vehicle data has resulted in missed opportunities for theft recovery and criminal apprehension.

The FBI provides a copy of the stolen vehicle file to authorized law enforcement agencies for their use in fixed and mobile license plate reader systems. The file can be obtained via ftp download or via an email update. The FTP update interval is once every 12 hours, the email update is sent once daily. To bridge the gap between updates, the FBI and Nlets have worked together to provide a real time feed of the file.

At the 9 character ORI level, users may select to receive real time updates using the Nlets AM message key. The feed includes entry, modify, and remove data from all reporting agencies in the United States. Nlets receives the feed directly from the FBI's NCIC system in real time and will broadcast AM messages from ORI AZNLETS00 to all users in the distribution list immediately upon receipt. The feed may be used to update the state's plate of interest file or system administrators may choose to programmatically update their devices in the field.

Users may subscribe and unsubscribe from the distribution list through their state Nlets Representative/CSO.
