To report someone you believe is engaged in prostitution, call your local police department’s non-emergency line. If anything about the situation suggests the person may be exploited or trafficked, call the National Human Trafficking Hotline at 1-888-373-7888 instead, or text 233733. Use 911 only if someone appears to be in immediate danger. Knowing how to report a prostitute effectively comes down to picking the right channel and giving the dispatcher specific, factual details rather than a vague suspicion.
Which Number to Call
Three channels handle almost every report.
Local Police Non-Emergency Line
For activity happening in your neighborhood, at a nearby business, or at a specific address, call your municipal police department’s non-emergency number, or the county sheriff’s office if you live in an unincorporated area. A dispatcher takes your information and routes it to the unit that handles vice, narcotics, or special investigations, depending on how the department is organized.
National Human Trafficking Hotline
Call 1-888-373-7888, text 233733, or use the live chat at humantraffickinghotline.org. The line operates 24 hours a day in more than 200 languages, and every contact is confidential.1National Human Trafficking Hotline. Contact Us Trained advocates screen tips and coordinate with local police and social services. This is the better first call whenever you think the person selling sex may not be doing so freely.
Federal Tip Lines
The FBI accepts tips through its online form at tips.fbi.gov, and you are not required to give your name.2Federal Bureau of Investigation.

One legal boundary worth naming: prostitution is illegal in every state except Nevada, where licensed brothels operate in about ten rural counties with populations under 400,000. Las Vegas and Reno are not among them. Everywhere else, both selling and buying sex is a criminal offense.
What to Have Ready Before You Call
The quality of your report drives what police can do with it. A vague complaint about “something suspicious” rarely leads anywhere. Specific facts do. Organize what you know into these categories before you dial:
- Location. The exact address, or as close as you can get. Include the building type, apartment or suite number, and any distinguishing features.
- Timing. When the activity happens and how often. “Every Friday and Saturday between 10 p.m. and 2 a.m.” is far more useful than “at night.” Patterns help police schedule surveillance.
- People. Approximate age, height, build, clothing, and distinguishing features of anyone involved. Note whether you’ve seen the same individuals repeatedly.
- Vehicles. Make, model, color, and license plate numbers if you can read them safely. Note recurring vehicles.
- Online activity. If the solicitation is happening through a website or app, provide the URL, username or profile name, platform name, and screenshots with visible dates and times.
Repeated observations over days or weeks carry more weight than a single sighting. Investigators look for patterns, so notes about recurring behavior help them build a case rather than chase an isolated incident.
Signs This May Actually Be Trafficking
A significant share of people involved in prostitution are not there by choice, and modern law enforcement increasingly approaches these situations by trying to identify victims before arresting them. Your report may be the first step in uncovering something more serious than a nuisance complaint. Watch for:
- Fearful or submissive behavior, or someone who defers to another person before speaking.
- A third party holding the person’s identification, answering questions for them, or driving them to and from the location.
- Branding tattoos (names, dollar signs, coded phrases), unexplained injuries, or clothing that doesn’t match the weather or setting.
- Living where they work, being unable to leave freely, or always being accompanied.
- Anyone under 18. Involvement of a minor in commercial sex is trafficking by federal definition, regardless of whether force or coercion is present.
Businesses that front for trafficking often show their own pattern: unusually late hours, employees who appear to live on the premises, locked doors with buzz-in entry, below-market pricing, and heavy surveillance cameras. When several of these appear together at a massage parlor, spa, or similar establishment, the trafficking hotline is the right call.
Gathering Information Without Putting Yourself at Risk
Do not confront anyone. Do not attempt a rescue. Do not follow vehicles or walk up to a location to get a closer look. Amateur intervention can compromise an investigation and put the potential victim in more danger.5Department of Homeland Security. How to Identify and Report Human Trafficking
What you can do safely: write down what you observe from a distance, note license plates from your own property or a public sidewalk, and take screenshots of online ads or profiles. Online content disappears quickly, so capture the full page, including the URL bar and any visible timestamps.
Recording conversations is a different question. Federal law requires only one party to consent, but roughly a dozen states require all parties to consent, including California, Florida, Illinois, Massachusetts, Pennsylvania, and Washington. Recording without proper consent in those states can expose you to criminal liability. When in doubt, stick to written notes and screenshots.
Anonymous or Named Reporting
Most channels let you stay anonymous. The FBI’s online form doesn’t require your name. The trafficking hotline keeps every contact confidential. Many local departments run anonymous tip lines, and some offer rewards for information that leads to arrests.
There’s a tradeoff. When investigators can’t reach you, they can’t ask follow-up questions. A tip that someone is “always there on weekends” might prompt a question about which weekends, or whether the pattern shifted recently. Without that back-and-forth, cases can stall.
Giving your name doesn’t turn you into a witness. Your information generally stays internal to the investigation, and you won’t be identified publicly unless you agree to cooperate as a witness in a proceeding. Calling in a tip and testifying are two very different roles.
What Happens After You Report
Don’t expect an immediate raid. Police typically use tips as building blocks for a larger investigation rather than acting on one call in isolation. After your report, officers may conduct surveillance, cross-reference your observations with other tips, or assign undercover work to verify what you saw.
Many departments now bring victim advocates along on prostitution-related operations. The current approach in most jurisdictions focuses on identifying who is being exploited and connecting them with housing, legal aid, and counseling, while building cases against the people profiting from the exploitation.
You probably won’t get updates. Investigations can run for weeks or months, and law enforcement rarely shares progress with tipsters. If you keep seeing the same activity, file another report. Consistent tips from the same location get noticed.
False Reports and Good-Faith Protection
Filing a knowingly false report is itself a crime. Under federal law, a materially false statement to a law enforcement agency carries up to five years in prison, and up to eight years when the statement relates to certain sex offenses or trafficking.6Office of the Law Revision Counsel. 18 USC 1001 – Statements or Entries Generally State penalties vary, but false reporting is typically a misdemeanor punishable by fines and up to a year in jail, with enhancements if the false report triggers a large emergency response.
None of this should scare you off a legitimate report. The false-reporting standard requires that you knew the information was untrue or made it up. Reporting something that turns out to be wrong is not the same as filing a knowingly false report. If you honestly believed what you observed suggested illegal activity and described it truthfully, you have met the good-faith standard even if the investigation finds nothing. Good-faith reporters are generally protected from civil claims like defamation, provided the report was based on genuine observation rather than a personal grudge or a fabricated claim.
