How to Find Someone in Custody in Massachusetts
There is no single 'Massachusetts inmate search.' State prisons, county jails, and federal facilities each keep their own rosters. The good news: all three layers are checkable online, free, from official sources listed here.
State custody: Massachusetts Department of Correction posts custody status through VINELink, the national victim-notification network — search by name, and register for release alerts while you're there.
County jails: a handful of Massachusetts counties post rosters online (linked below); for the rest, the sheriff's office answers custody questions by phone.
Federal custody: the Bureau of Prisons locator (bop.gov) covers federal defendants and anyone sentenced in US District Court — a separate population people forget to check.
Stay notified: VINELink sends automatic alerts when someone's custody status changes — transfer, release, or escape — in nearly every state.
Massachusetts routes custody lookups through VINE; county houses of correction — run by elected sheriffs — hold most short sentences. Content reviewed July 29, 2026 by the SearchSystems editorial team.
Search custody status and register for automatic notification when someone is moved or released. Free, run for victims but open to anyone. This is the primary online custody check for Massachusetts.
Beyond the Roster: Releases, Transfers, and Alerts
1
Set the alert instead of re-searching
Custody status changes without notice — transfers, releases, court dates. VINELink (linked above) does the watching for you: register the name and it calls or emails when status changes. It is the single most useful step for victims, families, and attorneys alike.
2
Check all three custody layers
People move between layers: county jail pre-trial, state custody after sentencing, federal facilities for federal charges. Massachusetts routes its state-custody lookups through VINELink rather than a separate DOC locator, so run VINE plus the county roster plus the federal BOP search to cover all three layers.

Get the records, not just the status
The roster shows where someone is; the paper trail lives elsewhere. Sentencing terms are in the court file (Massachusetts court records), and incarceration records beyond the public lookup are requested from the agency under the state records act — the Massachusetts records-law guide shows how.
Frequently Asked Questions
Is the Massachusetts inmate locator free?
Yes. Every official source on this page is free to search. Sites that charge for 'inmate reports' are reselling public data.
Why can't I find someone arrested yesterday?
Fresh arrests appear in the county jail's booking system first, sometimes hours later. State locators only list people after sentencing and transfer to state custody.
Does a locator listing mean the person was convicted?
No. Jail rosters include people awaiting trial who are presumed innocent. Check the court docket for the case outcome.
How do I send money or arrange a visit?
Each facility sets its own rules — the Massachusetts Department of Correction site covers state facilities, and each county sheriff posts local jail policies.
