Before you mail anything to Washington County Jail, there’s a real discrepancy worth knowing about: the Sheriff’s Office’s own website and the historic building’s official National Register of Historic Places listing give slightly different street numbers on Court Street in Machias. This guide walks through both, tells you what we could confirm about mail rules, and gives you the exact question to ask the jail before you send a letter or photo.
This is the most important thing on this page: the Washington County Sheriff’s Office’s current website lists its address as 85 Court Street, Machias, ME 04654. The jail building itself, listed on the National Register of Historic Places since 1988, gives its address as 83 Court Street, Machias, Maine, describing a three-story brick building built in 1858 that shares the block with the Washington County Courthouse next door.
An 1858 building and a website with a slightly different number for what’s likely the same address complex isn’t unusual for older municipal buildings, where a shared block, an added wing, or a separate mailing entrance can create small numbering differences over the decades. Rather than pick one number and risk your mail getting delayed or returned, call (207) 255-3434 before you mail anything and ask for the exact current mailing address, including whether personal mail should be addressed to the jail directly or to a different intake address.
The Sheriff’s Office’s own website doesn’t include a page describing:
Because none of this is published, don’t assume any rule based on what other Maine jails do. Call and ask before you send anything.
Call (207) 255-3434 and ask:
Once you’ve confirmed the correct address and any inmate ID or booking number requirement by phone, use a clear, consistent format on the envelope:
[Full Legal Name, Inmate Booking Number if provided]
Washington County Jail
[Confirmed Street Address]
Machias, ME 04654
Write clearly and double-check the spelling of the full legal name, since jails commonly reject mail with an unclear or mismatched name.
Attorney-client privileged mail is generally handled with additional protections at correctional facilities, sometimes including a rule that it can only be opened in the inmate’s presence. Washington County Jail’s specific legal mail procedure isn’t published on the Sheriff’s Office’s site. If you’re an attorney or legal representative, call (207) 255-3434 directly to confirm the correct process.
If your family member was recently booked, staff may not have set up their mail-related information yet. Call (207) 255-3434 to confirm the person is currently in custody before mailing anything, or check the inmate search guide for other ways to confirm.
