How to confirm the current facility
- Open the parent New Castle County inmate-search guide and identify the responsible sheriff, corrections department, detention center, regional jail, state agency, or other custodian.
- Use the verified custody method linked above.
- Confirm the exact facility name, booking or inmate number, current status, and jurisdiction.
- Open the official facility or agency page before sending mail, money, documents, or planning a visit.
- Reconfirm the location after court, medical transport, classification, contract placement, or transfer.
Why a jurisdiction can use more than one detention location
Delaware operates a unified state correctional system rather than separate county jail systems. Use the Delaware Department of Correction or its designated VINE pathway for custody information. A jurisdiction may use an intake center, main jail, annex, work-release center, city jail, regional authority, juvenile facility, medical unit, courthouse holding area, or contracted beds. The public agency result or official information line is the best current source for where an adult is housed.
Facility details to verify
| Detail | Why it matters | Where to verify |
|---|---|---|
| Official facility name | Prevents confusion with an old, renamed, closed, or informal jail name | Responsible agency or current inmate result |
| Operating agency | Identifies the correct locator, phone, mail, money, and visitation rules | Sheriff, corrections, regional authority, state, or contracted public portal |
| Street and mailing address | Physical location and inmate-mail address can differ | Current official facility page |
| Public information phone | Confirms urgent transfer or release questions when published | Official contact page |
| Custody population served | A building may handle intake, pretrial, sentenced, work-release, medical, or another group | Agency facility description |
| Search relationship | Shows whether the county search covers the facility or another system must be used | Locator coverage statement |
Mail, money, visitation, and phone services
Do not use a facility address or vendor from an old third-party page. Open the current official sheriff, corrections, jail, regional authority, or facility page and confirm the recipient format, inmate number, permitted items, vendor, visitation approval process, schedule, identification requirements, and communication rules. Transfers can invalidate previously correct instructions.
When the facility shown online changes
A location can change after court, classification, sentence, disciplinary action, medical care, protective placement, overcrowding, regional placement, contract housing, state transfer, federal hold, or release processing. A changed location does not by itself explain the person’s legal status.
State and federal alternatives
If the person has entered state custody, use the Delaware state inmate-search guide. The state agency is Delaware Department of Correction and the published state tool is Locate an Inmate. If federal custody is confirmed, use the federal BOP guide.
