Am I being followed? How to tell, and what to do

If you think you're in danger right now, call 911 and go somewhere public. If you're not sure, look for a pattern: the same person or vehicle showing up at different times, in different places, over a distance, and acting in ways that don't fit. One sighting is usually a coincidence. A pattern is worth writing down.

The pattern that matters

A common rule of thumb in surveillance work is to look for the same person or vehicle across time (you keep seeing them), environment (they turn up in unrelated places), distance (they're still there miles later) and demeanor (they act oddly, like stopping when you stop or looking away when you look). Busy roads and popular stores make overlap normal, so give more weight to places only you would plausibly go.

Signs you may be followed

1. The same vehicle appears behind you after several unrelated turns, or at two places on different days.
2. A car speeds up or slows down to match you, or lets others pass but not you.
3. A vehicle with someone sitting in it is parked near your home, work or gym again and again, especially early or late.
4. Someone pulls in after you and leaves when you leave.
5. The same person turns up on foot in different stores or neighborhoods.
6. Someone knows where you've been when you never told them. That points to a tracker or shared location more often than a tail.
7. Your phone warns that an unknown AirTag or tracker is moving with you (see below).
8. Unfamiliar logins, devices or location-sharing appear on your accounts.

If you think a car is following you

• Stay calm and keep driving legally. Don't speed, brake-check or try to "lose" anyone.
• Don't drive home. Head to a busy, well-lit public place or a police or fire station.
• Note the details: make, model, color, plate, damage, stickers, time and place. A dashcam helps.
• Call 911 if you feel unsafe, and tell the dispatcher where you are and what you're seeing.
• If police are trying to stop you, pull over safely when signaled.

Being "followed" by a tracker or your phone

Many people who feel followed are actually being tracked digitally. On iPhone, unwanted-tracking alerts need Bluetooth and Location Services on. Tap the alert to play a sound or use Find Nearby, and hold your phone near a found AirTag to see information about it, including its serial number. If you can't find it and feel unsafe, Apple advises going to a safe public place and contacting police (Apple). On Android, go to Settings → Safety & emergency → Unknown tracker alerts → Scan now (Google, Android Authority). Also check location sharing in Find My, Google Maps and Life360, your car's connected app and your phone plan (NNEDV Safety Net). Next: check your car for a GPS tracker.

Could it be a private investigator?

It might be. Investigators run surveillance for insurance claims, custody and divorce matters, and civil and criminal cases, usually watching from public places. A PI isn't a police officer. State law sets what they may do and whether they need a license. Watching someone in public is often legal. Stalking isn't: federal law makes it a crime to use mail, the internet, electronic communication systems or other facilities of interstate commerce in a course of conduct that puts a person in reasonable fear or causes substantial emotional distress (18 U.S.C. § 2261A). If you're unsure which one you're facing, document everything and talk to police or a lawyer.

Could it be the police?

There's no reliable way to tell from the outside, and this site can't tell you either. Our map shows where fixed cameras are mapped, not whether anyone is watching you. If you believe you're under investigation, talk to a criminal defense attorney.

Keep a simple log

Patterns are easier to show others when they're written down. For each sighting note the date, time, place, what you saw (vehicle, plate, person), what they did, and any photo or video. A log like this is what police, advocates or an investigator will ask for. Advocates also recommend documenting before you remove any tracker, because removal can alert the person and destroy evidence (Safety Net).

"Am I being followed, or am I paranoid?"

It's a fair question, and asking it doesn't mean anything is wrong with you. If you keep a log for a couple of weeks and nothing repeats, that's reassuring. If the fear is constant or keeps you from sleeping or working, talking to a doctor or counselor helps. You can call or text 988 any time (988 Lifeline). If someone you know, such as an ex-partner, is the worry, the National Domestic Violence Hotline (1-800-799-7233) can help you plan.
