James I. Montgomery Correctional Center, at 4727 Lannie Road in Jacksonville, is run by the Jacksonville Sheriff’s Office (JSO). Personal mail for anyone in JSO custody does not go to the facility itself. It goes to a centralized mail processing center where it’s scanned and delivered digitally to the inmate’s tablet, similar in concept to how FDOC handles mail for state prisons, though this is JSO’s own separate county system. Legal mail works differently and must go directly to the inmate instead of through the scanning center. Call 904-766-5076 or check jaxsheriff.org for anything not covered here.
Florida state prisons route all inmate personal mail through one centralized address in Tampa, where it’s opened, scanned, and delivered digitally. JSO runs its own separate centralized scanning system for Duval County, unconnected to the state FDOC system. If your family member is booked into JSO custody, including at James I. Montgomery Correctional Center, personal mail follows JSO’s process below instead of FDOC’s Tampa address, which does not apply here at all.
Address every personal letter or photo like this:
Jacksonville Sheriff’s Office, Duval, FL
[Inmate’s Name]
[10-digit booking number]
P.O. Box 247
Phoenix, MD 21131
Include the inmate’s full name, their 10-digit booking number, and your own return address on the envelope. Mail sent to this address is opened, scanned, and delivered to the inmate’s tablet instead of being handed to them as a physical letter.
Legal mail is not scanned or routed through the centralized processing center. If you are sending legal mail, meaning correspondence from an attorney, the courts, or another legal matter, address it directly to:
John E. Goode Pretrial Detention Facility
500 E. Adams Street
Jacksonville, FL 32202
This is the legal mail address for anyone in JSO custody, regardless of which specific JSO facility currently houses them. Even if your family member is housed at James I. Montgomery Correctional Center on Lannie Road, legal mail still goes to the Adams Street address above, not to Lannie Road and not to the Phoenix, MD personal mail address.
Only letters and photos are accepted by mail. There are no boxes and no oversized envelopes. The standard maximum size is 8.5 by 11 inches, so keep letters and photos within a normal envelope size.
All mail except legal mail is inspected for contraband before delivery. Since personal mail already goes through a centralized scanning process, this inspection happens as part of that scan. Legal mail is handled separately and is not part of this scanning and inspection process.
Magazines and newspapers are allowed only by subscription in the inmate’s own name, not forwarded by family or clipped from a personal copy. For books, only paperbacks are allowed, and only if they ship directly from Amazon, Books-A-Million, or Barnes & Noble. Hardback books are not allowed under any circumstances.
Inmates can keep up to 2 paperback books and 4 periodicals at a time. If an inmate already has the maximum, anything additional has to be mailed back out. Otherwise, it’s treated as contraband.
Photo quantity and size limits within the 8.5 by 11 inch format, and the typical turnaround time between when mail is scanned and when it appears on the inmate’s tablet, were not confirmed from an official source during this research. Call 904-766-5076 to ask about these specifics.
Mail that doesn’t meet these requirements, such as an oversized envelope or a magazine not sent by subscription, is typically rejected during the scanning and inspection process. If something you sent doesn’t show up on the inmate’s tablet, call 904-766-5076 to ask what happened.
Pigeonly is for personal letters and photos, the kind JSO scans at its Phoenix, MD processing box and keeps to 8.5 by 11 inches. Legal mail is a different path entirely: it goes unscanned to the John E. Goode Pretrial Detention Facility at 500 E. Adams Street in Jacksonville.
Once you’ve typed a letter or picked photos on your phone, Pigeonly sends the printed copies to the JSO processing box, P.O. Box 247 in Phoenix, MD, and covers the stamps. They’re scanned there and land on the person’s tablet at Montgomery like any other personal mail, so keep the 10-digit booking number handy.
