Monroe County Sheriff Office: Phone, Jail, Inmate Search & Locations
The Monroe County Sheriff’s Office is not a single downtown building serving one compact city. It covers the Florida Keys across roughly 125 miles of islands, with U.S. 1 and its mile markers acting as the main geographic reference from the Lower Keys through Marathon, Islamorada and the Upper Keys.
If you are trying to find someone who was arrested, check a warrant, locate the correct Sheriff substation, request a report, track civil papers or understand a jail visit, the quickest route is to use the specific Monroe County system for that task rather than calling every office in the Keys.
Which Monroe County Sheriff Resource Should You Use?
The biggest improvement over the old page is separating current custody, arrest history, warrants, court records, police reports and civil papers. They are not the same record and they are not searched in the same place.

Monroe County Sheriff Phone Numbers and Substation Locations
The Florida Keys’ long island geography makes the nearest office more important here than in many counties. MCSO maintains its administrative headquarters on Stock Island and official substations through the Lower, Middle and Upper Keys.

- Choose the nearest office rather than automatically driving to Key West.
- Call the location before travelling when you need a specific service.
- For urgent but non-emergency law-enforcement assistance, use the current MCSO non-emergency number.
How to Search Current Monroe County Jail Inmates
MCSO provides a dedicated Current Inmates page. Use it when your question is “Is this person in Monroe County custody right now?”
This is different from the Current Arrests page and historical Arrest Search. A person may have an arrest record after being released, while a current-inmate record is about present custody.
- Let the roster finish loading.
- Find the person using the legal booked name.
- Open or review the matching booking information.
- Save the inmate identifier.
- Write down the current charges, bond and housing information.
- Use the Clerk court-record search for the case itself.
Monroe County Has Three Different Arrest/Custody Searches

- Allow the latest-arrests list to load.
- Find the correct person by name and date.
- Compare the arrest details rather than relying only on a photograph.
- Use Current Inmates to see whether the person is still in custody.
- Use the Clerk court system for the later court case.
- Start with the last-name search.
- The official search supports a partial last name of at least three characters.
- For a narrower search, use the first-name and last-name fields supported by the form.
- Open the matching arrest record carefully.
- Check court records before drawing conclusions from an old arrest.
How to Search Monroe County Active Warrants
MCSO publishes an active-warrant directory arranged alphabetically by last name. Individual entries can include identifying information, charge information, warrant or arrest number, issue date and a listed bond.
The Sheriff’s warrant pages specifically warn users not to attempt to make an arrest or apprehension based on the information.
- Select the first letter of the person’s last name.
- Use the browser Find function if the page is long.
- Compare name, DOB and other identifying information.
- Review the listed warrant, charge and bond fields.
- Do not approach or try to detain the person.
- Use MCSO or Florida Keys Crime Stoppers to provide information safely.
Use the Monroe County Clerk for Criminal Court Records
The Sheriff’s arrest information answers what happened at the arrest or booking stage. The Monroe County Clerk of the Circuit Court is the better official source for filed criminal cases, court events and public case information.
The Clerk’s online system provides separate searches for criminal, traffic, civil, family and probate cases.
- Select Criminal Case Records when the matter involves a criminal arrest.
- Use the case number when you have it.
- Otherwise search the person’s legal name.
- Confirm Monroe County and the correct defendant.
- Review available filings, court events and disposition information.
- Contact the Clerk when you need an official or certified copy.

Need a Monroe County criminal-record search letter?
The Clerk’s current criminal FAQ says a Monroe County criminal-record search may be requested by mail or in person. The published search fee is $2 per year per person, plus $1 per page for copies and $2 per document for certification. The Clerk notes that this search covers Monroe County information only.
Monroe County Detention Is Spread Across the Keys
MCSO states that it operates detention facilities at Stock Island, Marathon and Plantation Key. That is a crucial local detail: the nearest Sheriff substation is not automatically the place where an inmate is housed.
Detention area |
Part of the Keys |
What to verify before travelling |
|---|---|---|
Stock Island / Key West detention campus |
Lower Keys |
Current inmate housing, visitation location and appointment |
Marathon detention facility |
Middle Keys |
Whether the inmate remains there or has been moved |
Plantation Key detention facility |
Upper Keys |
Housing status and current visitation instructions |
The Sheriff’s administration headquarters is at 5525 College Road. The main Stock Island detention campus is a separate jail function in the same general College Road complex, so do not assume the administration front desk is the correct entrance for a jail visit.
Monroe County Jail Uses Video Visitation
MCSO’s visitation material describes video visitation as the visitation method for Monroe County detention inmates, with both onsite and remote options.
The current Sheriff-hosted visitation flyer states that visits last 30 minutes, onsite/site-to-site visits are provided without a visit fee, and remote home visits carry the provider’s published charge. Because vendor rates and schedules can change, verify the live amount before paying.
- Confirm the inmate’s current detention facility.
- Review the current visitation provider.
- Create the required visitor account.
- Schedule the visit using the available onsite, site-to-site or remote option.
- Review current identification and dress requirements.
- Check the live provider fee before paying for a remote session.
- Keep the appointment confirmation until the visit is complete.
Phone account help
The Sheriff’s inmate-guideline material currently directs friends and family to 888-506-8407 for customer service involving inmate phone-account questions such as blocking or unblocking calls.
Verify the Inmate Identifier Before Sending Money or Mail
MCSO inmate guidelines require incoming personal mail to identify the inmate and include a complete sender return address. Because housing can change between Stock Island, Marathon and Plantation Key, check the live official guideline before mailing anything.
- Confirm the inmate’s booked name and jail-assigned ID or Perm Number.
- Read the current mailing-address format.
- Review prohibited property and correspondence rules.
- Use a complete sender name and return address.
- Review the current deposit/account instructions before sending money.
- Do not use a deposit provider copied from an unrelated Monroe County in another state.
Request Monroe County Sheriff Records Through the Official Public Portal
MCSO links directly to a JustFOIA public-record portal for Sheriff reports and other agency records. A public-record request is different from searching the Clerk’s court docket.
A precise request is easier to identify than “all records about this person.” When possible, prepare the incident number, date, approximate time, location, involved names and the exact document or recording you need.
- Select or start the appropriate Sheriff record request.
- Describe the record specifically.
- Add the MCSO incident or case number when known.
- Include the incident date and location.
- Identify the people involved accurately.
- Provide contact information for questions about the request.
- Wait for any cost estimate or production instructions before assuming the record is ready.
Ask the agency that created the report
Not every law-enforcement report generated in Monroe County belongs to MCSO. If Key West Police or another agency handled the incident, start with that investigating agency for its report rather than assuming the Sheriff maintains it.
Check Active Calls and the 7-Day Service Call Log
MCSO publishes public call information that can help users understand whether the Sheriff handled an incident and identify an incident number for a later report request.
The public service-call log covers a rolling seven-day period and can show fields such as incident number, date, time, general location, complaint type and disposition or offense information.
- Select the date page you need.
- Look for the general location or community.
- Compare the approximate incident time.
- Write down the MCSO incident number when shown.
- Use that number in a later Sheriff public-record request.
MCSO Civil Division Lets You Track Service of Civil Process
The Sheriff’s Civil Division serves court papers and executes qualifying writs. The MCSO civil page includes a status search that can be queried by a party name or case number.
- Use the party-name search with at least the required number of characters, or use the case number.
- Review the civil-process status.
- Open the fee information for your exact type of service.
- Confirm the required number and type of court-sealed copies.
- Confirm the current fee and payee before mailing documents.
- Include a self-addressed stamped envelope when required for a return of service.
MCSO warns that documents submitted with incorrect fees or an incorrect payee can be returned. This is especially important for landlords, attorneys and out-of-county litigants mailing papers into the Keys.
Examples of Sheriff civil services
- Summonses and subpoenas.
- Writs of possession.
- Writs of garnishment.
- Writs of replevin.
- Property levies.
- Out-of-state non-enforceable process.
- Special Process Server applications.
Sealing or Expunging a Florida Arrest Record Is a Separate Legal Process
If a Monroe County arrest was dismissed, resolved without conviction or otherwise falls into a potentially eligible category, removing public access is not accomplished simply by asking the Sheriff to delete the record.
The Florida Department of Law Enforcement explains that obtaining an FDLE Certificate of Eligibility is generally the first step for a court-ordered sealing or expungement. Eligibility depends on the exact record and Florida law.
- Identify which type of sealing or expungement may apply.
- Read the eligibility requirements and reasons for denial.
- Follow the Certificate of Eligibility application instructions when required.
- Keep copies of the disposition and application materials.
- Understand that an FDLE certificate by itself does not complete a court-ordered expungement.
FDLE currently says its eligibility-review processing time is typically about 12 weeks from receipt of a complete application packet and that applications are not expedited.
Local Details That Make Monroe County Different
MCSO describes a service area covering approximately 125 miles of islands connected by 42 bridges. That geography changes how people should approach Sheriff, jail and records tasks.
- Use the closest substation. A Key Largo or Tavernier resident usually does not need to start every routine question by driving to Key West.
- Save the mile marker. Along Overseas Highway, a mile marker can be more useful than a vague description such as “somewhere near the bridge.”
- Confirm detention location before travelling. Monroe County has detention operations at Stock Island, Marathon and Plantation Key.
- Expect U.S. 1 traffic to affect travel time. A scheduled visit should be treated like an appointment, not a quick drive across town.
- During major storms, check official notices first. Tropical weather can affect government access, court schedules, roads and detention procedures.
- Tourists should save incident numbers before leaving Florida. It makes follow-up record requests far easier after returning home.
- An arrest in Key West does not automatically mean MCSO created the incident report. Confirm the investigating agency.
- Do not confuse Monroe County, Florida with Monroe County, New York, Michigan or Georgia. Verify “Florida Keys” and Keysso.net before using a jail vendor.
What MCSO does beyond the jail
The Sheriff’s Office describes patrol and investigative operations as well as specialized capabilities including SWAT, Dive Team, Bomb Squad, Marine Unit, Major Crime Investigations and Special Investigations. It also provides detention and court-security services throughout the Keys.

Monroe County Sheriff Office FAQs
What is the Monroe County Sheriff non-emergency phone number?
The current Monroe County Sheriff’s Office website lists 305-289-2351 as its 24-hour non-emergency number. Call 911 for an emergency. Headquarters is listed separately at 305-292-7000.
What is the Monroe County Sheriff’s Office headquarters address?
Administration Headquarters is at 5525 College Road, Key West, FL 33040. Before travelling, confirm that administration is the correct location for your task because detention, civil process and Clerk services use other locations.
How do I search for a current Monroe County inmate?
Use the official MCSO Current Inmates page at Keysso.net/jailog. Verify the booked identity, save the jail-assigned identifier, review every listed charge and bond, and note the current detention location.
What is the difference between Current Inmates and Current Arrests?
Current Inmates answers who is presently in Monroe County custody. Current Arrests shows recent booking activity. A person may remain in arrest history after release, so the two searches answer different questions.
How do I search active Monroe County Florida warrants?
MCSO publishes an alphabetical Active Warrants directory. Select the first letter of the last name, compare identifying information and review the listed warrant details. Do not attempt to apprehend a wanted person yourself.
How do I find a Monroe County criminal court case?
Use the Monroe County Clerk of the Circuit Court online records search at cr.monroe-clerk.com and select Criminal Case Records. Search by case number when possible or use the defendant’s legal name.
Where are Monroe County detention facilities located?
MCSO states that detention facilities operate at Stock Island, Marathon and Plantation Key. Always verify the person’s current housing location through the official inmate record before travelling, mailing or arranging a visit.
How do visits work at Monroe County Jail?
MCSO uses video visitation with onsite and remote options. The Sheriff-hosted visitation information describes 30-minute visits. Check the live MCSO visitation page for the current provider, schedule, identification rules and remote-visit price.
How do I request a Monroe County Sheriff report?
Use the MCSO public-record request portal. Provide the incident number when known, date, approximate time, location, involved names and a specific description of the record. If another police department created the report, request it from that agency.
How do I track civil papers being served by the Monroe County Sheriff?
Use the MCSO Civil Division page and search by the party’s name or case number. Before sending new papers, verify the current statutory service fee, required copies and payee because documents with incorrect fees or payment information can be returned.
