Sending Mail to Tri-County Regional Jail

Mailing Address

Use this exact format for all inmate mail:

[Inmate Full Legal Name]
Tri-County Regional Jail
4099 State Route 559
Mechanicsburg, OH 43044

Write the inmate’s full legal name clearly. Nicknames or incomplete names may cause mail to be returned.

Letters and Cards

Standard letters and cards are accepted. Write clearly on plain paper in a standard envelope. Avoid envelopes with unusual coatings, padding, or metallic elements. Content that includes threats, describes illegal activity, or could compromise jail security may result in the mail being rejected and potential disciplinary action for the inmate.

Photos

The facility’s website does not specify photo rules. Call (937) 834-5000 before mailing photos to confirm:

• Whether photos are currently accepted
• Maximum number per envelope
• Accepted print size
• Content restrictions (no explicit images, no gang symbols)
• Format restrictions (no Polaroids, no laminated images)

Books and Magazines

The website does not publish book or magazine rules. Call (937) 834-5000 to ask whether books are accepted and whether they must come from an approved publisher or retailer.

No Cash in the Mail

Do not include cash in any envelope. To add money to an inmate’s account, use:

• Access Corrections at accesscorrections.com
• JailATM.com
• The lobby CyberSuite kiosk
• Phone deposit at 866-345-1884

See the Send Money guide for full details.

Legal Mail

Mail from attorneys, courts, and government agencies is treated as privileged legal mail. It is opened only in the inmate’s presence to check for contraband, then delivered sealed. Mark the envelope “Legal Mail” and include the attorney’s bar number or firm letterhead.

What to Do If Mail Is Rejected

If mail is returned, call (937) 834-5000 to ask why. Common reasons include prohibited content, missing inmate name, or items not permitted at the facility. Correct the issue and resend.
