Every day, millions of Americans pick up their phones to unknown numbers. Some ignore them; others answer, only to regret it. The evidence suggests that phone scams are more sophisticated than ever, and what we can verify is that they often prey on fear—especially when impersonating government agencies. If you’ve ever received a call claiming you missed jury duty or have a warrant, you’re not alone. But how do you know if it’s real?
The truth is, legitimate government agencies—like courts or law enforcement—rarely call citizens about serious matters. This remains unconfirmed but widely reported that most such calls are scams designed to intimidate you into paying money or providing personal information. Here’s what you need to know to protect yourself.
Why You Should Never Trust a Phone Call About Legal Trouble
The most common scam involves callers pretending to be from courts, IRS, or even the Sheriff’s office, claiming you missed jury duty or have an outstanding warrant. What we can verify is that these agencies almost always communicate via certified mail—not phone calls. If someone demands immediate payment or threatens arrest over the phone, it’s almost certainly a scam.
One telltale sign: they pressure you to act quickly, often demanding payment through untraceable methods like gift cards or wire transfers. This is a red flag that screams “scam.” Legitimate agencies won’t rush you or refuse to provide contact information for verification.
The Jury Duty Scam: How It Works and How to Spot It
The jury duty scam is particularly convincing because it plays on your fear of legal consequences. Callers claim you failed to appear for jury duty and now face arrest. They might even provide fake case numbers or courthouse details to seem legitimate. But here’s the catch: real jury summonses come via mail, and you can always verify any claim by contacting the courthouse directly.
If a caller insists you must pay a fine immediately or face consequences, that’s a dead giveaway. In reality, missing jury duty might result in a fine, but it’s not grounds for arrest, and certainly not something handled over the phone.
Why Voicemail Is Your Best Defense Against Scams
One of the smartest strategies is simple: don’t answer calls from unknown numbers. Let them go to voicemail. If it’s important, the caller will leave a message. This approach has worked for many who’ve avoided scams. The evidence suggests that scammers rarely leave voicemails because they know their ruse will be exposed.
If you’re still unsure, you can always call the agency back using a verified phone number from their official website—not the one the scammer provided. This small step can save you from falling victim to a scam.
Call Screening Apps: Do They Really Work?
Many people rely on call screening apps to filter out spam calls. While some, like Truecaller or carrier-specific services (e.g., AT&T Active Armor), can help, no app is foolproof. Scammers constantly adapt, and new tactics emerge. Still, combining app-based screening with your own skepticism is a smart approach.
The best “screen caller,” however, is yourself. If you don’t recognize the number, don’t answer. It’s that simple.
What to Do If You Suspect a Scam Call
If you receive a suspicious call:
- Hang up immediately. Don’t engage further.
- Verify independently. Call the agency directly using a number from their official website.
- Report the call. Many carriers and government agencies have systems for reporting scams.

Remember, no legitimate agency will threaten you or demand payment over the phone. If something feels off, trust your gut.
The Single Most Important Thing to Remember About Phone Scams
At the end of the day, scammers rely on fear and urgency. They want you to act before thinking. The most effective defense is to slow down, verify, and never give in to pressure. If it’s too easy to scare you, it’s probably a scam. Stay skeptical, stay safe, and protect your information at all costs.
