Montgomery Correctional Center Overview
The Montgomery Correctional Center is operated by the Jacksonville Sheriff's Office at 4727 Lannie Road in Jacksonville. The sheriff says it sits on the Northside and houses county-sentenced and some sentenced men and women. It is a county prison, the place people serve out shorter terms after a county sentence, rather than a pretrial intake jail. That distinction shapes everything from the population to the visiting rules.
The facility is the largest the sheriff runs by land mass. The 2023 Annual Report puts it at 418.59 acres, and the 2024 report lists 415.09 acres. It is split into North and South main housing units, which mostly hold men, plus a multipurpose Annex, also called the C-Building, that housed the female population in 2023. That spread of land and buildings supports the work crews and vocational shops the center is known for.
Montgomery Correctional Center Capacity and Population
The sheriff published both a design figure and recent daily counts for this prison. It was originally designed for 648 inmates. The average daily population ran above that line in both reported years, at 673 in 2023 and 665 in 2024. That is mild but steady pressure, since the count stayed over the original design figure across both years. The numbers come from the sheriff's annual reports.
The steady overcrowding has a straightforward cause. A county prison fills as the courts hand down county sentences, and Duval County's courts feed a consistent flow of sentenced people. With the count holding near 665 to 673 against a 648 design, the facility runs a little tight in both reported years. That pressure is part of why work crews and off-site assignments matter so much here, since they move eligible inmates into supervised work during the day and ease the load inside the housing units.
How to Look Up an Inmate at the Montgomery Correctional Center
Even though it is called a correctional center, this is a county facility, so its inmates are found through the JSO Inmate Information Search rather than the state prison locator. Open it from the JSO Inmate Information page or go to inmatesearch.jaxsheriff.org. Start with a last name, or use a booking number for an exact match.
- Open the JSO Inmate Information Search from the sheriff's inmate page.
- Search by last name, adding a first name to narrow common names.
- Use the number search if you have a booking or inmate number.
- Open the result to confirm the person is housed at this facility.
A person sentenced to a Florida state prison term instead appears in the Florida Department of Corrections locator, not here. The full roster how-to is on the jail inmate records page.
Montgomery Correctional Center Address and Contact
The prison has its own information line and several direct numbers for specific needs. Use the main prison information number for general questions, and the facility-access line for arranging permitted lobby business.
Montgomery Correctional Center
4727 Lannie Road
Jacksonville, FL 32218
904.630.8800
Prison information; facility access 904.630.8861
The prison lists several direct lines beyond the main number, including a clinic line for medical questions, a watch commander, and a property room for inmate belongings. For confirming whether someone is held here, though, the JSO inmate search and the main prison information line are the quickest routes. Save the specialized numbers for medical, supervision, or property matters once custody is confirmed.
Visiting Someone at the Montgomery Correctional Center
Public lobby access at the prison is limited. The sheriff lists it for attorney visits, court-ordered business, picking up inmate property limited to money and keys, and notary services restricted to Power of Attorney forms about medical care. Social contact follows the sheriff's video-visitation system. Because this is a sentenced-population prison on a large campus, confirm the current visiting schedule with the facility before traveling.
| Day | Hours | Type |
|---|---|---|
| Monday - Friday | By schedule | Attorney and court business; video |
| Saturday | By schedule | Video visitation |
| Sunday | By schedule | Video visitation |
As a sentenced-population prison, the center controls who enters more tightly than a facility built for daily visitor traffic. Lobby access is reserved for the limited business listed above, and social contact runs through the sheriff's video system. The Northside campus is also a drive from downtown, so confirming the current schedule and a person's housing assignment before leaving is well worth the call.
Mail, Phone, and Money at the Montgomery Correctional Center
Personal mail follows the countywide rule from October 1, 2024 and goes to the outside scanning center. Legal mail and authorized publications go to the facility, addressed with the inmate name and jail number at 4727 Lannie Road. Money is added through Access Secure Deposits online, by phone, or at a lobby kiosk. The sheriff will not accept cash or money orders for an inmate account in person or by mail.

How Inmates Arrive at the Montgomery Correctional Center
No one is booked into this prison off the street. People reach it after a county sentence, transferred from the downtown jail once their case is resolved and a sentence is set. From there, the focus shifts to programs and work. Sentenced inmates from state prison can be brought to the jail for release, but those serving county time at this center are managed here. The arrest, booking, and first-appearance steps all happen earlier, at the John E. Goode Pretrial Detention Facility.
Programs and Work at the Montgomery Correctional Center
The prison is built around work, and the sheriff credits its crews with real savings. The 2023 Annual Report tied more than 4.1 million dollars in savings to on-compound and off-compound work crews, the mattress factory, and uniform alterations. Sentenced inmates fill these roles as part of their county time, and the large Northside campus gives the prison room for shops and crews that the downtown jail simply cannot fit.
Vocational training is a major focus here. The welding program produced trained and certified welders, with several earning American Welding Society certification in a single year. The seamstress and mattress operation trained inmates while building over 1,000 mattresses, thousands of which were distributed across the sheriff's facilities. The goal behind these shops is to send a person home with a marketable skill rather than just time served.
The center also hosts the Paws for Change partnership with K9s for Warriors, which trains shelter dogs, some of which go on to become service animals. A range of classes rounds out the weekly schedule.
- Vocational welding and certification
- Seamstress, mattress, and uniform work
- Paws for Change service-dog training
- AA and NA recovery groups
- GED testing and adult literacy
About the Montgomery Correctional Center
The prison sits on the largest piece of land the sheriff operates, reported at roughly 418 acres in 2023 and about 415 acres the next year. It is divided into North and South main housing units, which mostly hold men, plus a multipurpose Annex known as the C-Building that has housed the female population. That layout lets the facility separate populations and spread its work programs across a wide campus. As a county prison rather than a pretrial jail, its day-to-day rhythm centers on sentenced inmates, structured work, and re-entry instead of the constant intake churn downtown.
Health and program standards at the prison are monitored against state and national benchmarks, the same framework the sheriff applies across its facilities. For families, the practical point is the search path. Even though it is called a correctional center, this is a county facility, so an inmate here is found through the sheriff's roster. Anyone sentenced to a Florida state prison term, by contrast, is searched through the state corrections system instead.
Note: Confirm custody and the current visiting schedule through the JSO search or the prison information line before making the trip to the Northside.
