City of St. Louis vs. St. Louis County: Key Difference
Missouri has a unique situation. The City of St. Louis is not part of St. Louis County. It is an independent city, meaning it functions like both a city and a county at once. The city has its own mayor, its own courts, and its own jail system run by the St. Louis Division of Corrections.
If someone was arrested within the city limits of St. Louis, they will be held at a city facility, not a county one. The city's corrections page is at stlouis-mo.gov. If someone was arrested in a St. Louis County municipality like Florissant, Hazelwood, or Kirkwood, they will likely be held at the county level.
When searching for an inmate, knowing whether the arrest happened in the city or the county makes a big difference. Ask the arresting agency or contact both systems if you are not sure where someone is being held.
