Visiting at Union County Jail starts with approval. Tennessee requires you to complete the Visitor Application (CR‑2152) and get cleared before scheduling any visit. Pick up the form from the facility's visiting office. Fill out every section, attach a current photograph, and list a street address (not a P.O. Box), then return it to the visiting office or the designated official. The facility runs an NCIC background check and typically responds with an approval or denial within about 30 days. Once approved, you'll schedule visits through the facility's scheduling system, which may be an onsite kiosk, a vendor portal, or a mobile app (scheduling windows and lead times vary). All visits are scheduled and monitored, and staff can change or cancel visits at their discretion.
