Cumberland County Jail publishes a detailed mail policy directly on the Sheriff’s Office website, and it’s stricter than what many county jails post publicly. The single most important rule: incoming personal mail, including postcards, must arrive in a white, legal-size envelope, a requirement the jail says helps with drug detection. Anything that doesn’t meet the guidelines gets returned to sender instead of delivered or held.
Send mail to:
[Full Legal Name]
C/O Cumberland County Jail
50 County Way
Portland, ME 04102
This address is confirmed directly from the Cumberland County Sheriff’s Office website. Always include your own return address on the envelope, since incomplete return addresses are specifically listed as a reason mail gets refused.
Every piece of incoming personal mail, including birthday cards and holiday postcards, must be sent in a white, legal-size envelope. The jail states this rule assists with drug detection in incoming mail. Any mail that doesn’t meet this requirement is returned to sender, with one exception: incoming legal mail is exempt from the white-envelope rule.
Photos can’t be larger than 4 inches by 6 inches. Instant camera photos, such as Polaroids, aren’t accepted in any size. Cards can’t be larger than 5 inches by 7 inches, and two-ply cards, musical or recordable cards, and any homemade or poster-style cards are all prohibited outright.
Cumberland County Jail publishes a specific, detailed list of items that will be refused, disposed of, or returned to sender. This includes:
Magazines, books, and newspapers are only accepted when they come directly from the publisher or from Amazon.com. Copies sent from any other outside source, including a family member repackaging a book they bought elsewhere, will be refused. Inmates are limited to 2 magazine subscriptions at a time.
Excluding weekends, holidays, and emergency situations, incoming and outgoing letters are held no more than 24 hours, and packages are held no more than 48 hours, before being processed to or from the inmate.
Legal mail from attorneys, courts, or government officials and representatives is handled differently from personal mail. It’s opened to check for contraband, but only in the presence of the inmate, protecting the confidentiality of the contents. Legal mail is also exempt from the white-envelope requirement that applies to personal mail.
For security reasons, Cumberland County Jail does not allow mail to or from anyone incarcerated at another juvenile or adult detention or correctional facility.
Mail addressed to someone who is no longer at Cumberland County Jail, whether they’ve been released or transferred, is marked “return to sender” and sent back with the next business day’s outgoing mail. Confirm the person is still in custody using the inmate search guide before mailing anything, especially a package or a large batch of photos.
Never mail cash, a personal check, or a second-party check. All three are specifically listed as items the jail refuses. See the send money guide for how to fund an inmate’s account instead.
