Montgomery State Prison Overview
Montgomery State Prison is operated by the Georgia Department of Corrections in Mount Vernon. GDC identifies the facility as a medium security prison for adult male felons and lists a public facility capacity of 900. The prison has its own address, phone number, fax number, mailing address, and state visitation schedule. It is separate from the Montgomery County Sheriff's Office and separate from any local arrest-processing question tied to the Montgomery County Jail and Sheriff's Office custody contact.
The distinction matters for inmate search. A person arrested in Montgomery County today is not automatically a Montgomery State Prison inmate. A state prison record usually appears after sentencing, transfer, or placement in GDC custody. GDC also warns that its offender information is best-effort and may include photos if available. State records should be checked against written correspondence or direct agency contact when exact custody status is important.
The facility screenshot below comes from the GDC Montgomery State Prison page, the official source for the prison's address, phone, capacity, population type, security level, and visitation hours.
That GDC facility page is the correct source for prison-specific rules because county jail web pages do not control state prison visits, mail, calls, or deposits.
Montgomery State Prison Population
Official sources give two different capacity contexts for Montgomery State Prison, and both should be attributed. GDC's public facility page lists capacity as 900 and describes the prison as medium security for adult male felons. The final PREA audit submitted November 24, 2025 gives a more operational snapshot: designed capacity 418, current population 405, average daily population 400 for the prior 12 months, day-one onsite audit population 406, population designation of men and boys, an age range from 18 to 80, minimum and medium custody, and no youthful inmates.
| Measure | Reported Figure | Official Source |
|---|---|---|
| Facility capacity | 900 | GDC public facility page |
| Designed capacity | 418 | 2025 PREA audit |
| Current population | 405 | 2025 PREA audit |
| Average daily population | 400 | 2025 PREA audit, prior 12 months |
| Custody level | Minimum/medium in audit, medium on GDC page | PREA audit and GDC page |
These numbers belong to state prison custody, not the Montgomery County jail population. The Georgia Sheriffs' Association jail report's no-jail entry for Montgomery County is a county jail reporting fact. Montgomery State Prison's population is part of the statewide GDC prison system.
Montgomery State Prison Lookup
Use the GDC locator for Montgomery State Prison inmate search. The GDC Find an Offender page is the public entry point, and the GDC offender query form supports name, physical-description, institution, conviction-county, GDC ID, and EF or case number searches. The institution dropdown includes Montgomery State Prison among statewide facilities. It may also show Montgomery County Jail as a dropdown option, but that does not turn the GDC tool into a local county jail roster.
- Open the GDC offender query form from the GDC Find an Offender page.
- Search by last name and first name, or use a GDC ID or EF/case number if known.
- Use the institution or conviction-county fields only as filters, not as proof of a local arrest record.
- Open the result and confirm that the most recent institution is Montgomery State Prison.
- For custody details that affect travel, mail, or money, verify with GDC or the facility before acting.
The state search image below comes from the GDC offender query disclaimer and form, which is the correct lookup path for Montgomery State Prison inmate records.
The form is useful when a person is in state custody, but GDC data may lag behind local arrest events and should not be treated as a same-day county booking list.
Montgomery State Prison Contact
Contact details for Montgomery State Prison come from GDC's public facility page. The street address should be used for facility location and visit planning after approval. The mailing address is the address used in GDC's prison mail format, with the offender's name and GDC number added. Phone and fax numbers are facility contacts, not substitutes for the statewide offender query when searching by name.

Montgomery State Prison Visits
Montgomery State Prison visitation follows GDC rules. The GDC facility page lists visiting on Saturdays, Sundays, and state holidays from 9:00 a.m. to 3:00 p.m. GDC's visitation guidance says visitors must be approved, visitor forms are submitted to the facility where the offender is housed, and email forms are not accepted. Scheduling can be handled through GDC's visitation system or GDConnect according to GDC instructions, with scheduling requests running Monday at 5:00 a.m. through Wednesday at 5:00 p.m.
| Day | Hours | Type |
|---|---|---|
| Saturday | 9:00 a.m. to 3:00 p.m. | GDC in-person visitation after approval |
| Sunday | 9:00 a.m. to 3:00 p.m. | GDC in-person visitation after approval |
| State holidays | 9:00 a.m. to 3:00 p.m. | GDC in-person visitation after approval |
| Scheduling window | Monday 5:00 a.m. through Wednesday 5:00 p.m. | GDC visitation scheduling request period |
GDC guidance also states that visit sessions can be up to two hours with up to four approved visitors. Rules can change by facility need, custody status, or GDC policy, so approval and scheduling should be confirmed before travel.

Montgomery State Prison Mail
GDC mail, phone, and money rules apply to Montgomery State Prison. Mail should include the offender's name, GDC number, the prison name, and the facility mailing address. For money, GDC lists money order, JPay online or mobile, phone, and MoneyGram. GDC's detailed money instructions say the sender must be on the approved visitor list and list MoneyGram receiver code Georgia DOC 6857. For calls, GDC identifies Securus Technologies at 1-800-844-6591, states that calls may be monitored or recorded, prohibits forwarding and three-way calls, and sets a maximum call time of 25 minutes.
| Service | GDC Detail |
|---|---|
| Offender name and GDC number, Montgomery State Prison, P.O. Box 256, Mt. Vernon, GA 30445 | |
| Money order | GDC-listed deposit option for approved senders |
| JPay | Online or mobile deposit path listed by GDC |
| MoneyGram | GDC receiver code Georgia DOC 6857 |
| Phone | Securus Technologies, monitored or recorded calls, no forwarding or three-way calls, 25-minute maximum |

Because these are GDC systems, they should not be used for a person who is only being checked for a recent Montgomery County arrest.
Montgomery State Prison Intake
State prison intake is not the same thing as street-arrest booking. A person reaches Montgomery State Prison through GDC placement after sentencing or transfer into state custody. The PREA audit describes the prison's population as minimum and medium custody, with an adult age range and no youthful inmates in the audit snapshot. Classification is the prison process that places a person by security need, housing, sentence factors, medical or mental-health needs, and other correctional rules.
- State-sentenced inmate
- A person serving a sentence in Georgia Department of Corrections custody.
- Most recent institution
- The facility field in GDC search that can show Montgomery State Prison when the person is housed there.
- Conviction county
- The county tied to conviction in state records. It may differ from the current prison location.
- GDC ID
- The state correction identifier used to search or address prison records and mail.
For current county arrest status, use Montgomery County custody contacts and court records instead of assuming the person entered prison custody. For state placement, GDC records and facility contact details are the better match.
About Montgomery State Prison
Montgomery State Prison is part of Georgia's statewide prison system and serves adult male felons under GDC authority. The facility sits in Montgomery County, but it houses state prisoners from the broader state system, not only people arrested in Montgomery County. That is why its capacity and population numbers must be shown apart from county jail statistics. The 2025 PREA audit gives more detail about current population, average daily population, custody level, and age range than the public facility page, while the GDC facility page supplies the public contact and visitation summary.
Note: Confirm custody, approval status, and visit scheduling with GDC before travel or deposits.
