Delaware has only three counties — New Castle, Kent, and Sussex — and operates a unified Department of Correction system. There are no traditional county jails. All sentenced inmates and most pre-trial detainees are held in Delaware DOC facilities, making the DOC search the single point of contact for the entire state.
New Castle County (Wilmington) is Delaware's most populous county and borders Pennsylvania. The Wilmington metro blends into the Philadelphia metro, and many New Castle County residents have Pennsylvania records. Delaware County Pennsylvania (a separate Pennsylvania county) is directly adjacent and commonly confused with Delaware the state. For broader context, see our Delaware people search guide and the three-tier inmate search overview.
Key takeaways
- Delaware DOC at doc.delaware.gov covers all state inmates — there are no separate county jails.
- Delaware courts are searchable through courts.delaware.gov statewide, covering all three counties.
- New Castle County (Wilmington) is part of the Philadelphia metro. Pennsylvania records are frequently relevant for Wilmington-area subjects.
- "Delaware County" in Pennsylvania is a completely different jurisdiction from the state of Delaware. Do not confuse the two.
Fastest path for a Delaware jail search
Start at Delaware DOC Inmate Search at doc.delaware.gov — one search covers the entire state. For court records: courts.delaware.gov. For Wilmington subjects with Philadelphia metro history: add Pennsylvania UJS search. When the DOC returns no result, a background report from Instant Checkmate confirms address history and any Pennsylvania cross-state patterns.
Delaware DOC: the unified system
The Delaware Department of Correction operates all correctional facilities. Delaware DOC facilities include Howard R. Young Correctional Institution (Wilmington), James T. Vaughn Correctional Center (Smyrna), and Sussex Correctional Institution (Georgetown). The DOC Inmate Search at doc.delaware.gov is free and returns current facility and sentence information.
Delaware courts
The Delaware courts portal at courts.delaware.gov provides statewide case search covering Superior Court (felonies) and Court of Common Pleas (misdemeanors) for all three counties. Delaware's court system is centralized at the state level consistent with its corrections structure.
Philadelphia metro cross-state pattern
New Castle County is functionally part of the Philadelphia metro. Wilmington is roughly 30 miles from Philadelphia. Many New Castle County residents commute into Pennsylvania, have prior Pennsylvania addresses, and may have records in Chester County, Delaware County (PA), or Philadelphia court systems. The Pennsylvania Unified Judicial System at ujsportal.pacourts.us covers Pennsylvania statewide and is the complement to a Delaware courts search for any Wilmington-area subject.
Also worth noting: Delaware County is a Pennsylvania county immediately north of New Castle County. The two are commonly confused. A search for "Delaware County" in the context of the Wilmington metro most likely refers to the Pennsylvania county, not the state of Delaware.
Federal facilities in Delaware
Federal cases in Delaware are handled by the District of Delaware (Wilmington). There is no federal correctional institution in Delaware. Federal inmates are typically sent to FCI Fairton in New Jersey or other Mid-Atlantic federal facilities.

Delaware participates in VINE at vinelink.com covering Delaware DOC facilities statewide.
Industry insight
Delaware is extremely simple to search — three counties, one DOC portal, one court system. The main complication is entirely geographic: New Castle County is physically and economically part of the Philadelphia metro, and Pennsylvania records are as relevant as Delaware records for most Wilmington-area searches. The Delaware County Pennsylvania name confusion catches researchers regularly. When someone says "Delaware County" in the context of a Wilmington search, confirm immediately which one they mean.
Why Delaware jail searches come back empty
- Very recent arrest still in police holding. Initial bookings through local police may not appear in DOC for 24-48 hours.
- New Castle County subject with Pennsylvania records. Wilmington metro subjects frequently have Pennsylvania court and address history.
- Searched "Delaware County" and found Pennsylvania records. Delaware County Pennsylvania is a separate jurisdiction entirely. Confirm which Delaware is meant before searching.
