Strengthening the Shield
50 Years of Memories and Milestones
Our Foundation
REJIS was established in 1974 as a joint venture between the City of St. Louis and St. Louis County as the first online information system returning stolen vehicle and vehicle registration information immediately to law enforcement officers. A commissioned study was published recommending the creation of one integrated criminal justice information system to serve the area’s 200 police departments, courts and corrections agencies. That regional criminal justice information system built the foundation for the present day REJIS. Today our developers, trainers, and client service professionals serve hundreds of agencies across four states from our state-of-the-art Data Center in St. Louis.
