How to Find an Inmate in Massachusetts

If someone you love was just arrested or sent to prison in Massachusetts, the first thing you need is also the hardest to get: a straight answer about where they are. Massachusetts does not have one single database that lists everyone in custody, and unlike most states it does not even run its own state-prison locator. Instead it points the public to a separate service. The person could be in a county house of correction, a state prison, a federal facility, or immigration detention, and each is searched a different way. One piece of good news: Massachusetts is one of the few states where staying in touch is free, including in county jails. This guide walks you through every system and tells you what to do when someone does not show up.

Start here: figure out which system is holding them

Before you search anything, answer one question, because it tells you which tool to use.

How long ago were they taken into custody, and what happened? Someone arrested in the last few days is almost always in the county house of correction for the county where the arrest happened, held by the county sheriff. In Massachusetts the county jails are called houses of correction. People do not go to state prison when they are arrested. They enter the custody of the state Department of Correction only after they are sentenced to a longer term and transferred.

So the rule of thumb is: recently arrested or case pending, look at the county house of correction. Sentenced to state prison time, search the state system through VINELink. Federal charge, look in the federal system. Immigration hold, look in ICE custody.

Searching the Massachusetts state prison system

Here is the first thing that surprises people: Massachusetts does not publish its own state-prison inmate locator. The state Department of Correction directs the public to VINELink, a separate notification and lookup service, to find someone in a state prison. You search by the person's full name or by their commitment number, the identification number assigned when they enter the system.

There is an important limit. Only the state Department of Correction and one county, Essex, participate in the Massachusetts VINE program. So VINELink will reliably find someone in a state prison or in the Essex County jail, but it will not find people held in most other county houses of correction. For those, you go to the individual county sheriff's website, covered next. If you are unsure whether your person is state or county, start with VINELink, and if nothing turns up, work the county angle.

Searching county houses of correction (recently arrested)

Massachusetts has 14 counties, and the county sheriff runs the house of correction in each, holding people awaiting trial and those serving shorter sentences. Each sheriff keeps its own roster, and because only Essex County feeds into VINELink, the rest are searched one at a time on the sheriff's own site.

The busiest systems are in and around the population centers: Suffolk County, which covers Boston, along with Middlesex, Worcester, Essex, Hampden County in Springfield, Plymouth, and Bristol counties. If you know the city or town, find out which county it is in and search that sheriff's roster, or call the house of correction directly. A booking or arrest date helps narrow it down.

Federal inmates in Massachusetts (BOP)

If the charge was federal, the person is in the custody of the federal Bureau of Prisons, not the state, and you search the BOP's own national inmate locator rather than any Massachusetts tool. It covers everyone in federal custody from 1982 to the present and searches by name or by federal register number.

Massachusetts has one federal prison, FMC Devens, in Ayer in the north-central part of the state. It is a federal medical center, which means it holds male inmates from around the country who need specialized or long-term medical or mental health care, alongside a minimum-security camp. Because it is a medical facility, a federal inmate from Massachusetts may be held elsewhere, and an inmate at Devens may be from far outside the state. The BOP locator finds them either way. If someone was just arrested on a federal charge and does not show there yet, check the county house of correction where the arrest happened.

ICE detainees in Massachusetts

If the person is being held on an immigration matter, they are in ICE custody, which is a civil detention system separate from criminal jail and prison. ICE detainees are not criminals serving sentences. They are held while their immigration cases are decided. You search for them using the federal ICE Online Detainee Locator, which works by the detainee's A-Number, a nine-digit immigration identification number, or by their full name, country of birth, and date of birth.

In Massachusetts, ICE detention is concentrated at the Plymouth County Correctional Facility, which has been the main facility holding people for ICE in the state, overseen by the ICE Boston field office. After two other Massachusetts counties ended their immigration detention agreements, Plymouth became the last one in regular use, so it is the first place to check, though detainees are sometimes moved to facilities in other New England states. Detainees at Plymouth cannot receive incoming calls, so contact runs through the facility's information line. Use the A-Number if you have it, since name searches in the immigration system are far less reliable when names are common.

When you cannot find them anywhere

If you have searched and your person is not turning up, work through these explanations before assuming the worst.

The booking is not complete yet. Newly arrested people can take hours to appear on a roster. Try again later the same day. You used the wrong tool. VINELink will not show most county jails, so if your person was recently arrested, search the county sheriff's roster instead. The name does not match the record. People are booked under legal names, middle names, maiden names, or misspellings. Try variations, and search with less information rather than more. They were moved between systems. Someone can be released, transferred, or handed from county to federal or immigration custody, and during the handoff they may briefly appear nowhere. They are a minor. Juveniles are not listed in public adult searches at all.

When the online tools fail, calling works. Call the house of correction or facility you believe is holding them, give the full name and date of birth, and ask to confirm custody status. That is often faster than any website.

Get notified automatically: VINELink

In Massachusetts, VINELink does double duty. It is both the way the state points you to find a state prisoner and the free service that sends automatic alerts about custody changes such as transfer or release. Register once, save your PIN, and you can get notified instead of checking over and over. Remember that the alerts, like the search, reliably cover the state Department of Correction and Essex County.

Once you have found them

Finding the person is the first step. Staying connected is the next, and here Massachusetts is unusually good to families.

Massachusetts made communication free. Under the state's No Cost Communications law, phone calls are free in both state prisons and county houses of correction, and the law also covers video calls and electronic messaging. Massachusetts was the first state to make calls free in its local jails, not just its prisons, so wherever your person is held in the state system, you should not be paying per minute to talk. If a facility tells you otherwise, that is worth questioning.

Mail still matters too. Letters and photos reach almost everyone in custody and are the most reliable form of contact, and a person who hears from home regularly does easier time. You can also send money to most facilities for commissary and basic needs. To set any of this up for the specific facility holding your loved one, find that facility on InmateAid and follow the instructions on its page, since the rules and the mailing address differ at every facility.
