What Is a Sheriff? Sheriff's Office vs. Police Department in the U.S.

A sheriff is typically an elected county official who leads a sheriff's office, while a police department serves a city or town and is usually led by an appointed chief. The practical difference for you: if you live in or are dealing with an unincorporated area, a county jail, court security, or civil paperwork like evictions and subpoenas, the sheriff's office is usually the right agency. If you're inside city limits, the local police department is usually your first contact. These are general patterns, not fixed rules — titles, duties, and even whether a sheriff is elected vary by state and county.

The core distinction: county vs. city

The word "sheriff" itself refers to the person, and "sheriff's office" (or "sheriff's department" in some places) refers to the agency. In a few states the office is called something else, and in some counties the sheriff's law enforcement role is limited or shared with other agencies.

What a sheriff's office typically does

Beyond patrol, sheriff's offices often handle functions that police departments usually don't:

• County jail operations — running the local detention facility and managing inmates.
• Court security — providing bailiffs and securing courthouses.
• Civil process — serving subpoenas, eviction notices, restraining orders, and other legal papers.
• Patrol of unincorporated areas — covering parts of the county that aren't inside any city.
• Warrant service and prisoner transport — moving people between jails and courts.

Not every sheriff's office does all of these, and some do more. A sheriff's office in a county with no large city may look and act much like a police department.

Which agency should you contact?

Use the location and the type of issue as your guide:

• Inside city or town limits, general emergency or crime → call 911; the responding agency is usually the local police, though sheriff's deputies may respond in some areas.
• Unincorporated county area → the sheriff's office is usually the primary law enforcement agency.
• Jail, inmate, or booking question → the sheriff's office, since it typically runs the county jail.
• Court security or courthouse issue → the sheriff's office.
• Civil papers (eviction, subpoena, order) → the sheriff's office handles service in most jurisdictions.
• Non-emergency local question → start with the agency whose boundary you're in; if unsure, the county sheriff's office can usually point you to the right one.

When jurisdiction overlaps — for example, a city that also contracts with the sheriff for certain services — the safest approach is to call the non-emergency line of either agency and ask which one covers your address.

How to find the right agency

USACOPS is an online law enforcement directory that lists police departments, sheriffs' offices, and other agencies across the United States. Its homepage presents a clickable state map and a state list (Alabama through Wyoming, plus Washington D.C.) to browse departments by state. The site also includes options to view and post jobs, add or modify a department, and update department information.

A practical lookup sequence:

1. Identify whether your address is inside a city/town or in unincorporated county land.
2. If inside a city, look up that city's police department.
3. If in unincorporated land, look up the county sheriff's office.
4. Use a directory such as USACOPS to find the agency by state, then confirm the non-emergency number on the agency's own page before relying on it.

Keep in mind

• Titles vary. Some agencies use "sheriff's department," "constable," or other names, and duties differ by state.
• Election rules vary. In many places the sheriff is elected, but this isn't universal.
• Overlap is normal. City, county, state, and federal agencies can all have a role in the same area; the sheriff's office is often the county-level default.
• For emergencies, always call 911 rather than trying to pick the agency yourself.
