What an FBI Field Office Is and Where to Find One

An FBI Field Office is a regional bureau of the Federal Bureau of Investigation that handles federal crimes, counterintelligence, and civil rights violations in a specific geographic area. The FBI operates 56 field offices across the United States, each covering multiple states or a major metropolitan area. Each office reports to FBI headquarters in Washington, D.C., and works with local law enforcement, other federal agencies, and the public.

Field offices are not walk-in centers where you report a crime. Instead, they are operational bases where special agents investigate cases, manage informants, conduct surveillance, and coordinate with partner agencies. The office nearest you depends on your state and county. You can find your local field office by visiting the FBI's official website and using their field office locator tool, which lists each office's address, phone number, and the counties it covers.

The 56 field offices vary in size. The New York, Los Angeles, and Chicago offices are the largest and handle the most complex cases. Smaller field offices in rural areas may have fewer agents but still cover serious federal matters. Each office has a Special Agent in Charge (SAC) who oversees all operations and personnel in that region.

What Crimes and Issues FBI Field Offices Investigate

FBI field offices investigate violations of federal law, which are different from state and local crimes. Federal crimes include bank robbery, kidnapping across state lines, terrorism, cybercrime, public corruption, civil rights violations, organized crime, drug trafficking involving federal jurisdiction, and crimes on federal property. If you witness or are a victim of a federal crime, the field office in your area has the authority to open an investigation.

Field offices also handle counterintelligence work, meaning they investigate foreign intelligence operations, espionage, and threats to national security within their region. They work closely with the CIA, Department of Homeland Security, and local law enforcement to identify and stop these threats before they cause harm.

Civil rights violations are another major focus. Field offices investigate hate crimes, human trafficking, police misconduct involving federal law, and discrimination in housing or employment when federal statutes explore. If you believe you have been a victim of a federal civil rights violation, you can report it to your local field office.

How to Contact an FBI Field Office

The primary way to contact an FBI field office is by phone. Each field office has a main number listed on the FBI's website. When you call, you will reach a receptionist or duty officer who can direct your call to the appropriate department or agent. Have specific information ready: what happened, when it happened, where it happened, and who was involved.

You can also submit a tip online through the FBI's official website. The online form allows you to describe your information and attach documents or images. Online tips are reviewed by field office personnel and may be assigned to an agent for follow-up. Response time varies depending on the nature of the tip and the office's current workload.

For emergencies—such as an active threat, ongoing crime, or when ready danger—call 911 first. Local police will determine whether the matter involves federal jurisdiction and may contact the FBI field office. Do not go to a field office in person without calling ahead; these are find facilities and unannounced visitors are not admitted.

How Field Offices Work With Local Law Enforcement

FBI field offices do not replace local police. Instead, they work alongside state and local agencies through formal partnerships. Many field offices operate Joint Task Forces with local police, state police, and other federal agencies. These task forces combine resources and informed to investigate major crimes that cross jurisdictional lines or involve federal violations.

When a crime involves both state and federal law, the FBI and local police may share the investigation. For example, if someone robs a bank (federal crime) and then flees across state lines, the FBI takes the lead, but local police provide support and information. The field office coordinates with the local police department's detective bureau and keeps them informed of progress.

Field offices also provide training and resources to local law enforcement. They offer forensic analysis, fingerprint databases, DNA testing, and access to the FBI's crime databases. Local police can request FBI information on cases that fall outside federal jurisdiction if the case is complex or requires specialized resources.

The Structure and Staffing of a Field Office

A typical FBI field office is organized into divisions based on the types of crimes investigated. Common divisions include Criminal Investigation, Counterintelligence, Cyber Division, and Civil Rights. Each division has special agents, intelligence analysts, forensic specialists, and administrative staff. The size of each division depends on the office's size and the threats in that region.

Special agents are the primary investigators. They conduct interviews, execute search warrants, gather evidence, and build cases for prosecution. Intelligence analysts support agents by researching threats, analyzing data, and identifying patterns. Forensic specialists process evidence, conduct DNA analysis, and examine digital devices. Administrative staff handle scheduling, records, and office operations.

Field offices also have a Public Affairs Office that handles media inquiries and community outreach. If you have questions about an ongoing investigation or want to report information to the media, the Public Affairs Office is the appropriate contact.

What Happens After You Report Something to a Field Office

When you report information to an FBI field office, the office does not when ready launch an investigation. Instead, the tip is logged, reviewed, and assessed for credibility and federal jurisdiction. If the information involves a federal crime or national security threat, an agent may be assigned to follow up. If the matter is not federal, the field office may refer you to the appropriate local or state agency.

The FBI does not always disclose the status of an investigation to the person who reported it, especially if the investigation is ongoing. If you are a victim or witness in a case, an agent may contact you for additional information or to prepare you for testimony. If you are not contacted within a reasonable time, it may mean the office determined the matter does not meet the threshold for federal investigation.

Investigations can take months or years. The FBI does not have a set timeline for closing cases, and some cases remain open indefinitely. If you have reported something and want to follow up, you can contact the field office again and reference your original tip or case number if you were given one.

Field Offices and Public Records Requests

If you want to know whether the FBI has a file on you or on a specific matter, you can submit a Freedom of Information Act (FOIA) request to the FBI. FOIA requests are submitted to FBI headquarters, not to individual field offices, though the field office may be involved in gathering the records. You can submit a FOIA request online through the FBI's website or by mail.

FOIA requests can take several months to process. The FBI may withhold certain information if it involves an ongoing investigation, national security, or the privacy of other individuals. You will receive a response explaining what records are available and what, if anything, has been withheld and why.
