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.

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.
