Inmate Lookup: Nantucket County, Massachusetts

The Nantucket Police Department inmate lookup page is the county-level resource for confirming whether someone is currently held in Nantucket County. Nantucket is a single-island county where the Police Department handles local custody; there is no separate county jail facility distinct from the police lockup. Search by name or call (508) 228-1212 if the online page does not return results. A new booking can take time to appear online, so a phone call is the faster path for recent arrests.

Searching the Nantucket County jail roster

A booking on Nantucket typically means the person is held at the Nantucket Police Department, the island’s primary law-enforcement and holding facility. The department’s website is the county-level resource for custody status. New bookings can take time to appear online; if you need immediate confirmation, call (508) 228-1212 directly.

1. Go to the Nantucket Police Department page.
2. Look for the custody or records section, or call the main line to ask about a specific person by name.
3. Have the full legal name and approximate date of birth ready — these are the fields most useful for a custody inquiry.
4. For broader sheriff-level information, the Nantucket County Sheriff’s Office listing on the Massachusetts Sheriffs’ Association site provides additional contact context.

Nantucket is a small, geographically isolated county. Arrests made by the Nantucket Police Department are the primary source of local custody records; Massachusetts State Police also operate on the island and may book individuals through the same facility.

What the roster does (and doesn’t) show

Juvenile records are not displayed on any public-facing custody roster in Massachusetts. Sealed records under M.G.L. c. 276, §§ 100A–100C are similarly withheld from public view. Individuals held on federal charges appear in federal custody systems only — the local Nantucket roster will not reflect a federal detainee. People transferred to a Massachusetts Department of Correction state prison after sentencing drop off the local roster entirely and appear instead in the Massachusetts DOC inmate lookup.

The roster also reflects only current custody. Someone released on personal recognizance or bail will no longer appear, even if their case is still active in court. Charges listed at booking may change before arraignment. A new booking can take time to appear online, so an absence from the roster does not confirm release — particularly in the hours immediately following an arrest on this island, where the booking process runs through a single facility.

If someone was just booked tonight

Call the (508) 228-1212 — the Nantucket Police Department’s main line — to confirm custody right now. That’s the fastest path on this island, and it’s a hard night to be waiting on a website. The line handles custody inquiries around the clock, not just during business hours.

The person who was booked has the right to one phone call. They may not have made it yet — that’s normal, not a sign something has gone wrong. Processing takes time, and on a small island facility the pace can vary. If you haven’t heard from them, it doesn’t mean they can’t call.

Bond is not set at booking. A judge decides bail at the first appearance in court, which happens after the booking process is complete. Calling the Police Department tonight confirms whether someone is in custody; it will not tell you the bail amount, because that number doesn’t exist yet. Ask when the first appearance is scheduled — that’s the question worth asking tonight.

Visitation is not available the night of a booking. That part is the hard part. Hours for visits begin the following day; call the department in the morning to confirm current visiting procedures for the Nantucket facility. Confirm numbers and hours before visiting or calling the next day.

Morning actions: contact the Nantucket District Court Clerk’s office to get case information once a docket number is assigned. Attend the first appearance if possible — bond is set there. If you need an attorney, the Committee for Public Counsel Services handles public defender assignments in Massachusetts, and the Mass.gov lawyer referral resource can help locate private counsel.

If someone isn’t on the Nantucket County roster

An absence from the Nantucket Police Department’s custody page most often means the booking hasn’t yet propagated to the public-facing record — a new booking can take time to appear online. That’s the most common explanation for a same-day search that returns nothing.

• State DOC transfer: If the person was sentenced or transferred to a state facility, search the Massachusetts Department of Correction inmate lookup — county rosters do not reflect state prison placements.
• Released: Bail or personal recognizance release removes a person from the active roster. Call (508) 228-1212 to confirm whether a release occurred.
• Neighboring county: An arrest made off-island or transferred to Barnstable County (the nearest mainland county) would appear in Barnstable’s custody system, not Nantucket’s.
• Federal custody: Federal charges route to federal detention facilities. The local Nantucket roster never displays federal detainees.
• VINELink: The statewide victim notification and custody-status service can surface custody status across Massachusetts facilities and may catch transfers the local roster doesn’t reflect.

If you can’t find them in Nantucket County

A nationwide third-party records search may help surface custody records from other states or federal systems that local and state portals don’t reach. The search is designed to query across multiple jurisdictions and may include records from facilities beyond Massachusetts — useful when you’re not certain where someone is held.
