GPS Tracking Laws in the US: What Families Need to Know


There is no single federal law that says who may track whom. What exists is a mix of Supreme Court rulings on government searches, a federal stalking statute, and a patchwork of state laws. For a family, the practical rule is simple: tracking your own property, your own pet, or a minor child you are responsible for is generally on solid ground, while tracking another adult without their knowledge and consent is where people get into trouble, including criminal trouble in many states.

This guide walks through what the law says, where states differ, and how to set up family tracking so it stays clearly on the right side. It is general information, not legal advice. If a custody dispute, a protective order or a business is involved, talk to a licensed attorney in your state.

TL;DR

  • No comprehensive federal geolocation privacy law existed as of the most recent GPS.gov summary, so state law and the federal stalking statute do most of the work for families.
  • Tracking a person without consent can be a crime. Florida, for example, treats it as a third-degree felony.
  • Parents can generally track minor children, caregivers can track seniors under narrower conditions, and adults need to agree to be tracked.
  • Pet and personal-property tracking is the least contested use, but the device must not end up tracking another person.
  • The safest setup is open: the person knows, agrees where they can, and can see what is shared.

What federal law actually covers

Most of what people call “GPS tracking law” at the federal level is about the government, not about you and your family.

The Fourth Amendment protects against unreasonable searches. In United States v. Jones (2012), the Supreme Court held that installing a GPS device on a suspect’s vehicle and monitoring its movements is a search. In Carpenter v. United States (2018), it ruled that obtaining historical cell-site location records without a warrant violates the Fourth Amendment. The GPS.gov privacy page notes that as of October 2018 no comprehensive federal geolocation privacy law had been enacted.

The Department of Justice has told Congress that federal investigators generally need a warrant based on probable cause to monitor a device’s precise location going forward, with exceptions such as consent and life-and-death emergencies.

What this means for you: these cases limit police and prosecutors. They do not give a private person a free pass, and they do not forbid a parent from putting a tracker in a child’s backpack. The rules that touch families live elsewhere.

The federal stalking statute

The one federal law that regularly reaches private tracking is the stalking statute. 18 U.S.C. § 2261A covers a course of conduct, carried out across state lines or through interstate communications, that places a person in reasonable fear of death or serious bodily injury or causes substantial emotional distress. Its language also reaches conduct aimed at a pet, service animal, emotional support animal or horse.


A tracker used openly to keep a family safe is nothing like that. A tracker hidden on someone who did not agree to it, used to follow them, is exactly the pattern legal aid groups describe. Illinois Legal Aid Online notes that tracking devices can be misused to follow people without consent, and that federal stalking law and state law can criminalize it.

Why state law is the one that matters

The states went their own ways. A Congressional Research Service report from 2026 counts nineteen states with comprehensive data privacy laws that regulate geolocation data, and notes that Congress has debated preempting these laws to reduce inconsistency. Older CRS analysis already described state approaches to GPS as ranging from warrant requirements to no specific electronic tracking statute at all.

In practice, three kinds of state rules affect families:

  1. Standalone tracking-device crimes. These make it an offense to place or use a tracker to follow another person without consent.
  2. Stalking and harassment laws that name electronic tracking. Here the tracker is evidence of a broader course of conduct.
  3. Consumer data privacy laws. These regulate how companies collect and handle location data, not what you do as an individual.

The same act can be a felony in one state, a misdemeanor in another, and not specifically addressed in a third. So always check your own state’s statute, and the state where the person you are tracking lives or travels.

Example: Florida

Florida’s statute is unusually detailed, which makes it a useful illustration. Under Florida Statutes § 934.425, it is generally prohibited to knowingly install a tracking device or application on another person’s property, or to use one to determine another person’s location or movement, without that person’s consent, subject to listed exceptions. Unauthorized tracking is classified as a third-degree felony, or a second-degree felony if it is used to commit or facilitate a dangerous crime.

The same statute spells out the family situations that most readers ask about, which we cover below.

Example: California

California’s Penal Code 637.7 makes it unlawful to use an electronic tracking device to determine another person’s location or movement without consent. It also contains exceptions, such as for the registered owner, lessor or lessee of a vehicle and certain employer uses. If you live in California and your situation falls near an exception, a local attorney can tell you how courts have read it.

Can you put a tracker on your own car?

Generally yes, when the vehicle is yours. This is the most common question next to the main keyword, and the answer rests on ownership and consent. Florida, for example, exempts a vehicle owner or lessee who uses a tracker during ownership or lease, provided it is removed before title transfer or lease expiration, unless specified consent or manufacturer-notice conditions apply.

Where families get caught out is co-owned or shared cars. If your spouse, an ex-partner or an adult child is the primary driver, “my name is on the title” may not settle it. A car you co-own with someone you are separating from is a situation to take to a lawyer before you install anything.

Tracking your child

Parents have broad authority over minor children, and a tracker in a school bag or a child’s wearable is a common, lawful use. Florida’s statute, for instance, allows a parent or guardian to track a minor child’s property under defined circumstances: when the parents are married and living together, or when the parent has sole custody. It also says consent is presumed revoked once a petition for dissolution of marriage or an injunction is filed.

Two lessons apply nationwide even where the wording differs:

For children’s data specifically, the device maker has obligations too. Our checks for child location tracking and COPPA explain what to look for.

Tracking an adult family member

An adult is not your dependent, and the law treats them that way. Whether it is a spouse, a partner, an adult child or a parent, the baseline is consent. The consent should be real: freely given, understood, and revocable. An adult who says yes under pressure has not really agreed, and one who withdraws consent has changed the legal picture.

If you want a tool that works on consent, use one that shows it. Apps for sharing location work when the person gives permission, and a device the person carries openly, knowing it reports to a shared map, sits in the same category.

Seniors and caregivers

Families caring for a parent with dementia face the hardest version of this question. Many states have no rule written specifically for it, so consent from the senior, or authority from a legal guardian or agent under a power of attorney, is the safest footing. Florida gives one clear model: a caregiver may use a tracker on an elderly or disabled adult’s property, or to determine that person’s location or movement, if the treating physician certifies it is necessary for the person’s safety.

Whatever your state, talk to the senior’s doctor, and to an elder law attorney if capacity is in question. Then document the decision. Our page on GPS trackers for seniors and the guide to sharing location with grandparents when phones fail cover the practical side.

Pets and personal belongings

Tracking a dog, a cat, luggage or a bike you own is the least legally contested use. The one thing to watch is the edge case: a collar tracker that goes home with a dog walker, or a tracker placed in a bag someone else carries, can end up telling you where a person is. If the device is following a person, the consent rules above apply to that person.

It is also worth knowing that the federal stalking statute names animals among the protected victims of a harassing course of conduct, so the law does not treat pets as an afterthought. Using a tracker to find your own dog is lawful. Using one to harass a neighbor about theirs is not.

Perspective: what we think good tracking looks like

We built Kin One around one idea: a family should be able to see where everyone is, and everyone in the family should know that. That is why the device has no microphone for audio monitoring and no onboard camera, and why privacy controls, including route deletion and user-managed visibility, are part of the design rather than an add-on.

Legally, the safest tracking is also the most respectful tracking. Kids know the tracker exists. Seniors are asked and their answer counts. Pets get a collar. If you ever find yourself hoping the person will not discover the device, that is the signal to stop and reconsider, whatever your state’s statute says.

We would also say this about the law itself: it is changing, and it differs by state. Use our guides as a starting point and the statute as the final word.

Setting up family tracking the legal way

A few habits keep you well inside the lines, no matter where you live:

  1. Tell people. Explain what the device does, what you can see and why you want it.
  2. Agree on the rules. Decide who sees what, when, and for how long. Our two-week trial for location sharing etiquette is a good way to start.
  3. Limit what is stored. Delete routes you do not need, and prefer devices that let you do so.
  4. Know how to turn it off. If a family member wants out, revoking location access should be easy and respected.
  5. Check the company. Our guides on GPS tracker privacy and warrants and what families should check about data privacy list the questions to ask any maker.
  6. Use a checklist. Our family safety checklist walks through setup for kids, pets and caregivers.

Where Kin One fits

Kin One is a GPS tracker and app that puts kids, pets and parents on a single map, with live updates, arrival and departure alerts, and up to five approved emergency contacts. It costs $99 once, with no monthly fees, includes lifetime network data and a two-year warranty, and leaves out audio monitoring and cameras on purpose. If you want to see how it works for your household, start with the Kin One product page, or browse the pages for kids, pets and seniors.

A device does not change the law: you still need the right to track the person who carries it. What it can do is make the open, consent-based approach easy.

FAQ

Is it illegal to track someone with a GPS device?

It can be. Many states criminalize using a tracker to follow another person without their consent, and the federal stalking statute can apply when tracking is part of a course of conduct that causes fear or serious distress. Parents tracking minor children and owners tracking their own property are the usual lawful cases. Check your state’s statute for the details.

Is it illegal to put a tracking device on a vehicle you own?

Usually not, because ownership is the main exception in state laws. Florida, for example, exempts an owner or lessee, with conditions about removal before title transfer or lease end. If someone else drives the car regularly, or you are separating from a co-owner, get legal advice first.

Can someone track my location without my knowing?

Technically yes, which is why the laws exist. Tracking devices can be misused to follow people, and doing so without consent can be a crime under state and federal law. If you think this is happening to you, contact local law enforcement or a domestic violence advocate.

Do I need a warrant to use a GPS tracker?

No, a private person does not need a warrant. Warrant rules in cases like Jones and Carpenter limit the government. A private person is limited by consent, ownership and state criminal law instead.
