Mason County Regional Detention Center Overview
Mason County Regional Detention Center, also called Mason County Detention Center, is a full-service regional county jail operated by the Mason County Jailer and Mason County. The address is 702 US 68, Maysville, KY 41056. The jail is not a Kentucky state prison, even though the county page says it houses state inmates. In practical terms, that means a person may be held before trial, while serving a short local sentence, while awaiting transfer, or as a state inmate assigned to a county jail bed. Sentenced Department of Corrections custody is searched through KOOL, not only through the county roster.
The official Mason County detention overview says the center opened in 1990, houses state inmates, and houses inmates for Mason, Bracken, Fleming, and Lewis Counties. Robertson County is not expressly listed in that county sentence. The reason this page treats Mason as the best documented serving facility for Robertson County users is narrower: Kentucky KOOL lists Robertson County Jail as closed, Robertson County does not publish its own current-inmate page, and 2025 local reporting described a Robertson County sheriff booking at Mason County Detention Center. That is an evidence-based custody path, not a quoted interlocal contract.
The Mason County overview is the best starting source for jailer, hours, programs, and official links.
The overview also links readers to the separate Mason County Detention Center jail website, Kentucky court resources, KOOL, Kentucky State Police, and VINE, which is why lookup usually uses more than one system.
Mason County Regional Detention Center Capacity and Population
Current official Mason County pages inspected for this build do not publish a live certified capacity, current population count, daily average, or Robertson-only jail population. The only sourced bed figure located for this specific facility is older correctional-facility data: Prisoners of the Census / Census 2020 data lists Mason County Detention Center as a local facility with 145 beds and a facility date of December 31, 2013. That number should be read as a historical sourced capacity figure, not a current official county certification.
How to Look Up an Inmate at Mason County Regional Detention Center
For a person believed to be in current regional jail custody, start with the Mason County Regional Detention Center current-inmates page. If that roster is unavailable, incomplete, or too slow to show a new booking, call the jail at (606) 564-3621. For a person who has been sentenced to Kentucky DOC custody, transferred to a state correctional facility, or placed under DOC supervision, use Kentucky Offender Online Lookup (KOOL). Kentucky VINE can be used for custody-status notifications, but it should not be treated as a substitute for direct jail confirmation before travel, bond, or release planning.
- Open the Mason current-inmates roster first for people believed to be in county or regional jail custody.
- Search by name, and compare identifying details carefully because spelling and recent bookings may lag.
- Confirm the listed location is Mason County Regional Detention Center before relying on mail, visitation, or deposit instructions.
- If the roster does not answer the question, call (606) 564-3621 and ask for current custody confirmation.
- If the person is sentenced, transferred, or under Kentucky DOC supervision, search KOOL instead of relying only on the jail roster.
Mason County Regional Detention Center Address and Contact

Visiting Someone at Mason County Regional Detention Center
Mason County's FAQ describes video visitation through an off-site vendor rather than ordinary walk-in contact visits. Outside visitors register through InmateSales. Onsite and offsite visits are recorded and monitored. Onsite visits use the lobby kiosk, and the visit must be scheduled before the kiosk can be used. The FAQ says inmates receive up to two free 15-minute onsite video visits per week.
The official Mason County detention FAQ is the source for visitor rules, dress-code examples, money, phone, and contraband warnings.
Because the FAQ does not publish a fixed public visiting calendar by day and hour, scheduling through the vendor and confirming with the jail is the safer route before anyone drives from Robertson County to Maysville.
| Visit Option | Schedule / Limit | Type |
|---|---|---|
| Onsite lobby kiosk | Must be scheduled before use | Recorded and monitored video visit |
| Free onsite allotment | Up to two 15-minute onsite video visits per inmate per week | Lobby video visit |
| Remote/offsite video | Register through InmateSales; facility policies apply | Off-site video visit |
| Before travel | Call (606) 564-3621 if the roster or vendor schedule is unclear | Custody and visit confirmation |
For onsite visits, bring a government-issued ID and one set of vehicle keys only. Leave phones, bags, and other items in the vehicle unless staff gives different current instructions. Visitors are subject to search. The FAQ warns that inappropriate behavior, nudity, profanity, inappropriate language, or improper dress may cause visitation privileges to be revoked. Prohibited dress examples include excessive short shorts or skirts, see-through clothing, tops showing too much cleavage, and clothing condemning a race, religion, or ethnic group. The contraband warning cites KRS 520.010, 520.050, and 520.060.
Mail, Phone, and Money at Mason County Regional Detention Center
Incoming mail must include the inmate's name, inmate ID, and a return address. The full current mail-scanning and prohibited-item page was not available during research, so confirm the mailing format and any photo, postcard, book, or scanning restrictions with the jail before sending items. For money and phone time, Mason documents several separate channels. Commissary funds and phone products are related, but phone time is not the same thing as commissary.
| Service | Provider / Detail | Notes |
|---|---|---|
| Mail address | Inmate name and inmate ID, Mason County Regional Detention Center, 702 US 68, Maysville, KY 41056 | Return address required; confirm prohibited items and scanning policy before mailing. |
| Commissary money | Money order by mail, lobby kiosk, or JailATM.com | Current fees were not published in the research materials. |
| Phone / video account | InmateSales direct pay, calling card, pin debit, lobby kiosk, or 1-877-998-5678 | Phone time is separate from commissary, although inmates may add phone time through commissary if they have funds. |
| Funds after release | Call the next business day; debts are deducted and checks may be mailed | Use (606) 564-3621 ext. 12 for release-of-funds questions. |
Booking and Intake at Mason County Regional Detention Center
A Robertson County arrest can involve more than one office. The arresting agency may be the Robertson County Sheriff's Office, Mt. Olivet Police Department, another Kentucky agency, or an out-of-county agency. The jail record begins when the person is accepted and booked into custody at the detention facility. New bookings may not appear on the public roster immediately, so the phone fallback matters for bond, release, or transportation questions. If a person is held on a warrant, court order, probation or parole matter, or another county's hold, the jail roster may not tell the entire court story.
County jail booking information is also different from court records. The jail can confirm custody and may show booking charges, bond, and release status. The Robertson Circuit Court Clerk or the relevant Kentucky court docket is the better path for filed charges, court dates, case numbers, and dispositions. When a person becomes a sentenced DOC offender, KOOL may show the current location, DOC or PID number, parole eligibility, sentence dates, and photo availability. That statewide system is why a state inmate housed in a county jail should still be checked in KOOL when the question is about DOC status.
About Mason County Regional Detention Center
Mason County's official materials identify Lisa Yeary as jailer and describe the detention center's mission around public safety, institutional security, and programs intended to reduce reincarceration. The published program list includes GED classes, a Substance Abuse Program, Moral Reconation Therapy, gardening classes, and outside inmate work programs for roadside litter pickup and residential trash pickup. Medical care is contracted and available seven days a week.
No accreditation status, PREA audit report, current population dashboard, recent inspection report, or Robertson-specific inmate population breakdown was found in the official materials reviewed. That absence should not be filled with guesses. For a specific person, use the Mason roster, call the jail, use VINE for notifications, and use KOOL for sentenced or DOC custody.
Note: Confirm custody, visit approval, schedule, mail rules, and deposit options with the facility before traveling or sending money.
