The Frederick County jail roster is a public resource that lists individuals currently held at the Frederick County Adult Detention Center in Maryland. FrederickCourt.us can help you find publicly available information about current and recent inmates, including booking details and charges. You can also access jail roster information through the Frederick County Sheriff's Office website, by calling the detention center directly, or by visiting in person. The roster allows the public to confirm whether someone is in custody, view the charges against them, and check basic booking data. The Frederick County Sheriff's Office maintains the roster as part of its Adult Detention Center operations, and the information is updated on a regular basis.

Find Frederick Jail Booking Records Online
A booking record is created each time an individual is processed into the Frederick County Adult Detention Center. This happens after an arrest, when the person is formally received by the facility.
Information Generated at Booking
Each booking record typically includes:
- Booking number (a unique identifier assigned to that intake)
- Date and time of booking
- Charges at the time of intake
- Arresting agency (e.g., Frederick County Sheriff's Office, Frederick Police Department, Maryland State Police, etc.)
- Personal identifiers such as name, date of birth, and physical description
- Bond or bail amount, if set
How to Access Booking Records
Current booking records for people still in custody are generally accessible through the jail roster. For records beyond what the roster shows — such as past bookings or detailed intake documents — you may need to submit a public records request. Under the Maryland Public Information Act, many jail records are accessible to the public, though certain information (such as medical or mental health records) is restricted.
To request records from the Frederick County Sheriff's Office, contact the Adult Detention Center directly at (301) 600-1600. For records related to arrests made by city police, you can submit a public records request to the Frederick Police Department.
Search the Frederick Jail Roster by Last Name or Booking Number
The Frederick County jail roster supports two primary search approaches:
Search by Last Name
- Enter the inmate's last name into the search field, or scroll through the roster alphabetically.
- If available, add the first name to narrow results — this is especially helpful for common surnames.
- Use correct spelling. If you're unsure, try alternate spellings or shortened versions of the name.
Search by Booking Number
If you have the booking number (sometimes provided by the arresting agency or through court documents), enter it directly. This is the fastest way to pull up a specific record, since each booking number is unique.
Tips for Better Results
- Use the person's full legal name, not a nickname or alias.
- If the roster supports partial name searches, try entering just the first few letters of the last name.
- Double-check for typos — even a single wrong letter can return no results.
If the Search Returns No Results
A blank result does not necessarily mean the person was never booked. It may mean:
- The person has already been released and their record has been removed from the active roster.
- They were booked under a different name or spelling.
- They are being held at a different facility (such as a state prison). Try the DPSCS Incarcerated Individual Locator.
- Booking data has not yet been entered into the system.
If you still can't find someone, call the detention center at (301) 600-1600 and ask staff to check directly.
Jail Roster Updates and Search Limitations in Frederick
The Frederick County jail roster is updated on a regular basis as new bookings and releases are processed. However, there are practical limitations users should be aware of.
Update Frequency
Roster data is generally refreshed throughout the day, but there can be a delay between when someone is physically booked into the facility and when their name appears on the public roster. This lag may range from a few hours to a full business day, depending on intake volume and staffing.
Known Limitations
| Limitation | What It Means for Users |
|---|---|
| Booking-to-roster delay | A recently arrested person may not appear on the roster immediately. |
| Post-release removal | Once an inmate is released, their record is typically removed from the active roster. The roster is not a historical archive. |
| Data entry lags | Charge updates, bond changes, or transfers may not reflect instantly. |
| Current custody only | The roster shows people currently held at the Adult Detention Center — not individuals on probation, parole, or housed at state facilities. |
| No juvenile records | Minors are excluded from the public roster entirely. |
For older or historical booking records, you may need to file a records request with the Sheriff's Office. The Maryland State Archives also maintains historical government records for Frederick County in various formats. For criminal background checks that go beyond the jail roster, the Maryland DPSCS background check service provides a more comprehensive option.
