The Oakland County Sheriff's Office offers three ways to send mail to inmates that are incarcerated. You can send regular US postal mail, legal/business mail, and electronic messages (e-mail). Inmates will be granted access to a tablet on which they can view the mail and photos you send to them. Note: Mail and electronic messages are subject to monitoring at any time. There is no expectation of privacy.
Standard US Postal Mail
You can send letters, photos, postcards and greeting cards to the inmate through our mail vendor, Smart Communications. Do not send mail directly to the Oakland county jail! Please make sure the inmate's name and inmate's number are clearly printed on the envelope or postcard to ensure it will be readily available for him/her.
To send money orders (no cash) to an inmate, see "How Do I Send Money to an Inmate?" at the top of this webpage. For other standard US postal mail, send to the following address:
Oakland County Jail
Inmate Name – Inmate Number
PO Box 9103
Seminole, FL 33775-9103
Legal/Business Mail
Attorney correspondence, court documents, bank statements, magazines and newspapers can be sent directly to the jail at the following address:
Oakland County Jail
Inmate Name – Inmate Number
PO Box 436017
Pontiac, MI 48343
Electronic Messages (Email)
Instead of spending 75 cents (on average) for US postal mail, you can send up to 30,000 characters (equivalent to 6-7 pages) via a computer or Smartphone through SmartInmate Communications. Simply go to the website www.smartinmate.com, sign up for an account, and make a minimum deposit of $5.00 + a one-time $1.50 setup fee, and you can send messages to your inmate for 50 cents each, and $1.00 per photo. Every Saturday, each inmate is entitled to two (2) free messages (one incoming, one outgoing).
Upon release from Oakland County Jail, inmates will be able to log into www.smartinmate.com, enter their inmate number and password, and download a copy of all postal mail, messages and photos for free. For assistance or additional information regarding SmartInmate Communications, please call toll-free 888-843-1972. You can also sign up for an account on www.MailGuardTracker.com to receive notifications when your mail is received and read by the inmate. If any mail is rejected, you will be notified as to the reasons why.
