South Carolina GPS Tracking Laws: Is It Legal to Put a Tracker on a Car? (2026)

South Carolina never passed a law regulating who may put a GPS tracker or an AirTag on someone else's car. The phrase "tracking device" does appear in the code, but only in S.C. Code 17-30-140, which sets out how law enforcement gets a court order to use one. Nothing in the code speaks to private tracking. That does not make secret tracking legal.

Instead, South Carolina prosecutors reach for the harassment and stalking statutes, which ban "following" a person and keeping them under "surveillance." A hidden GPS unit on someone's car fits that language better than most people expect. This guide walks through how the law actually works, who can track a vehicle legally, and how South Carolina's unusual carve-out for licensed private investigators works.

Is It Legal to Put a GPS Tracker on a Car in South Carolina?

It depends on whose car it is and why you are tracking it. Putting a GPS device on your own vehicle is legal. Putting one on someone else's vehicle without their knowledge is where the trouble starts.

Because South Carolina has no statute regulating private use of tracking devices, there is no single bright-line rule that says "placing a tracker on another person's car is a crime." Instead, the question becomes whether your tracking behavior amounts to harassment or stalking under S.C. Code Title 16, Chapter 3, Article 17. In practice, secretly tracking an ex, a spouse, or anyone else over time almost always checks those boxes.

The state-of-mind element matters. A single, isolated act is usually not enough, because the statutes require a pattern. But a GPS tracker is never really a single act. It reports the victim's location over and over, day after day, which is exactly the kind of repeated conduct the harassment law was built to punish.

No Private-Tracking Statute: Harassment and Stalking Fill the Gap (16-3-1700)

S.C. Code 16-3-1700(A) defines harassment in the first degree as a pattern of intentional, substantial, and unreasonable intrusion into someone's private life that causes mental or emotional distress. The statute then lists examples of what that intrusion can look like, and two of them map directly onto GPS tracking.

The first is "following the targeted person as he moves from location to location." A GPS tracker is electronic following. It does precisely what a tail car would do, just more efficiently and around the clock.

The second is "surveillance of or the maintenance of a presence near" the targeted person's home, workplace, school, or other place they visit. A device that reports when someone arrives at and leaves their house or office is surveillance in the plainest sense of the word. Neither GPS units nor AirTags are named anywhere in the harassment statute, but conduct of that kind fits the statutory language directly, and the section says its examples are illustrative, not exhaustive.

One step up from harassment sits stalking, which is defined in S.C. Code 16-3-1700(C) and punished under S.C. Code 16-3-1730. Stalking is a pattern of words or conduct that serves no legitimate purpose and is intended to cause, and reasonably would cause, the victim to fear death, assault, bodily injury, kidnapping, or property damage. When GPS tracking is part of a broader campaign of intimidation, the charge escalates from harassment to stalking, and the penalties jump with it.

The Private Investigator Exemption (16-3-1700(G))

Here is what makes South Carolina genuinely distinctive. Section 16-3-1700(G) lists conduct that the harassment and stalking provisions do not apply to. Alongside constitutionally protected activity, law enforcement officers, and process servers performing official duties, the legislature carved out licensed private investigators.

The exemption covers a PI "performing services or an investigation as described in detail in a contract signed by the client and the private investigator pursuant to Section 40-18-70."

Read closely, though, subsection (G) says only that "this section does not apply." It removes liability under the harassment and stalking definitions, and nothing more. It does not authorize trespassing onto private property to reach a vehicle, it does not authorize tampering with a car the client does not own, and it does not bar a civil suit for wrongful intrusion into private affairs. An investigator who bolts a tracker to a stranger's car is still exposed on each of those fronts.

Many states leave PIs in a legal gray zone or limit them to vehicles the client owns, so an express statutory carve-out like South Carolina's is unusual. Private investigators here are licensed and regulated by the State Law Enforcement Division (SLED), so the carve-out only protects investigators who hold a valid license and stay within the scope of the signed contract.

The exemption is not a loophole for ordinary people. Hiring yourself as your own "investigator" does not work, and an unlicensed person who tracks someone for pay commits both the underlying offense and a licensing violation.

Who CAN Legally Track a Vehicle in South Carolina

Some tracking is clearly lawful. The common categories look like this.

Your own vehicle. You can put a GPS unit on a car titled in your name, including anti-theft trackers and devices that monitor a teen driver. If a spouse co-owns the car, ownership gives you a strong defense, although using the data to intimidate or follow your spouse can still support a harassment charge.

Fleet and business vehicles. Companies routinely track vehicles they own. South Carolina has no statute restricting employer GPS tracking of company property.

Parents and guardians. Tracking your minor child's phone or the family car is lawful. Courts treat parental monitoring of minors as a legitimate purpose.

Licensed private investigators. As covered above, PIs operating under a signed client contract have an express exemption in 16-3-1700(G). It lifts harassment and stalking liability only, not trespass, tampering, or civil exposure.

Law enforcement with a court order. S.C. Code 17-30-140 is the one place the code addresses tracking devices by name. It lets the Attorney General or a solicitor apply to a judge for an ex parte order authorizing installation and use of a mobile tracking device on a certification of probable cause, and subsection (E) expressly adopts "the standards established by the United States Supreme Court for the installation and monitoring of mobile tracking devices." That folds in United States v. Jones, 565 U.S. 400 (2012), where the Court treated the physical installation of a GPS tracker on a vehicle as a Fourth Amendment search, so police generally need a warrant before planting one.

Lenders and lienholders. Vehicles financed through buy-here-pay-here dealers often come with disclosed GPS units tied to the loan agreement. Consent in the contract is what makes those lawful.

Can My Employer Track My Car in South Carolina?

South Carolina has no statute addressing employer GPS tracking, so the default rules apply. If the vehicle belongs to the company, the employer can track it, on or off the clock, because the employer owns the asset.

Your personal vehicle is different. An employer who hides a tracker on an employee's private car without consent has no ownership defense and risks the same harassment exposure as anyone else, plus a civil wrongful-intrusion claim. Employers who want location data from personal vehicles used for work should get written consent, typically through a mileage-tracking app the employee installs voluntarily.

AirTags and Item Trackers

Apple AirTags, Tiles, and similar Bluetooth trackers are treated no differently than a wired GPS unit under South Carolina law. The harassment statute looks at the conduct, following and surveillance, not the technology.

Dropping an AirTag in someone's bag or magnet-mounting one in a wheel well is the same legal act as bolting on a $200 GPS tracker. Apple and Google now push unwanted-tracker alerts to nearby phones, which is how many South Carolina victims discover the device in the first place. Those phone alerts, plus a police report, become the core evidence in a harassment prosecution.

Using an AirTag to find your own stolen property is lawful. The line is tracking a person who has not consented.

Penalties for Illegal GPS Tracking in South Carolina

Because tracking is charged under the harassment and stalking statutes, the penalty depends on the degree of the offense and your record.

Federal law can stack on top. 18 U.S.C. 2261A, the federal stalking statute, covers using "any interactive computer service or electronic communication service or electronic communication system" to engage in a course of conduct that causes substantial emotional distress or fear, and it applies when the stalker crosses state lines or the tracking spans states.

Civil Options and Restraining Orders

Criminal charges are not the only remedy. South Carolina recognizes the tort of wrongful intrusion into private affairs, the state's version of intrusion upon seclusion. A victim of covert GPS tracking can sue the tracker for damages, and the secrecy of the device usually makes the "intrusion would be highly offensive" element easy to prove.

For faster protection, S.C. Code 16-3-1750 gives magistrates court jurisdiction over an action for a restraining order against a person engaged in harassment or stalking, and lets any person file the complaint and motion. Venue is the county where the defendant lives, where the conduct happened, or where the plaintiff lives if the defendant is a nonresident or cannot be found.

The emergency mechanism sits in the next section. Under S.C. Code 16-3-1760(A), within twenty-four hours after the complaint is filed the court may hold an emergency hearing and, for good cause, issue a temporary restraining order without giving the defendant notice. A prima facie showing of present danger of bodily injury, verified by supporting affidavits, counts as good cause. Violating the order then exposes the tracker to the enhanced penalties in the table above.

What to Do If You Find a Tracker on Your Car

Stay calm and think about evidence before you act.

1. Photograph the device in place before touching it. Location and mounting method matter to investigators.
2. Do not destroy it. The tracker is evidence, and it may carry fingerprints or a serial number that identifies the buyer.
3. Call local police or the sheriff's office and ask them to document and remove it. Mention S.C. Code 16-3-1700 if the officer is unsure what statute applies.
4. Save phone alerts. If your iPhone or Android flagged an unknown AirTag traveling with you, screenshot the alert and its history.
5. Consider a restraining order. If you know or suspect who placed it, file the complaint in magistrate court under 16-3-1750. The emergency route in 16-3-1760 lets the court hold a hearing within twenty-four hours of filing and issue a temporary order without notice to the defendant when there is a present danger of bodily injury, and an order in effect stiffens the penalties for continued tracking.
6. Talk to a lawyer about a civil claim if the tracking caused real harm, since wrongful-intrusion damages are separate from any criminal case.

If you are in danger, the National Domestic Violence Hotline (1-800-799-7233) can help you plan around a tracker without tipping off the person monitoring you.
