Phone Numbers You Should Never Call: The Real List

The phone numbers you should never call, one reason each

Seven kinds of number belong on the real list. None of them is a ghost story.

1. A number that rang once. A missed call from an unfamiliar number can be bait: a callback can reach a number outside the US that charges a connection fee and per-minute rates, and the FCC advises you not to call back (FCC). The pattern has its own page: the Wangiri one-ring scam.
2. A number a threatening caller gives you. A caller who says you missed jury duty or face arrest, and gives you a number to call or pay, is running a scam. The section below shows what the FTC says.
3. A pay-per-call (900) number. A 900 number charges by the call or the minute. In most areas you can ask your phone company to block 900 numbers on your line (FCC).
4. An old campaign line. Studios often rent numbers for a film or game, and when a rental ends a phone company can give the number to a new owner. One game line seems to have a new owner, and a 2017 Stranger Things promotion line was later reported to play a Medicare-related recording (The Ghost In My Machine). We do not print either number. A call could reach a person or a business, not a story.
5. A number whose owner asked to be left alone. The Eastwood Industries number was removed from The Ghost In My Machine's list at the owner's request. We never print it.
6. A prank call to an emergency or crisis number. These lines exist for people in danger, and a prank call can delay help for someone else. The law is on is prank calling illegal.
7. A number from an undated list. If a list does not say when each number was checked, some entries may now belong to strangers.

Scammer numbers to call for fun: why it goes wrong

Do not call them. A number on a scammer list may be one the scammers only borrowed: the FCC explains that scammers falsify caller ID, often to look local (FCC). The person who owns the number may have nothing to do with the scam, and your prank lands on them.

That makes every number on a scammer list one of the phone numbers you should never call. Answering may also tell a scammer that your line is live, as scam texts can (FCC alert). The FCC's advice for unwanted calls is not to answer numbers you do not know, and to hang up right away if someone asks for money or personal information (FCC). Pranking a stranger can also break the law. If you want to hit back, report the scam at ReportFraud.ftc.gov.

What to do when a caller threatens you

A caller says you missed jury duty and will be arrested unless you pay. It is a scam. According to the FTC, real law enforcement will not call to threaten arrest, courts and government agencies do not demand payment by phone, and only scammers insist on payment apps, cryptocurrency, gift cards or wire transfers (FTC, June 2026).

Hang up, as the FCC advises when a caller asks for money or personal information. Check with the court using a number you look up yourself (FTC, March 2025), and report the call at ReportFraud.ftc.gov. Caller ID can be faked, so an official-looking number proves nothing. In 2024, consumers filed 284,659 reports to the FTC saying a scam began with a phone call, with $948 million reported lost and a $1,500 median loss; these are unverified consumer reports (FTC data book 2024).

What about FaceTime calls?

Treat an unexpected FaceTime call from a number you do not know as untrusted, and decline it. Apple asks people to email a screenshot of a suspicious FaceTime call to [email protected] (Apple).

Why a number from an old list can now reach a stranger

A campaign line is usually rented, not owned. When the rental ends, the number can go back into the pool, and a business or a household may get it next. The FCC said in 2017 that about 35 million US numbers are disconnected and reassigned each year (FCC, 2017).

Lists written years ago keep circulating and videos keep being filmed from them, so every list needs dates, and the new owner can receive calls meant for a story. If a child called a number from a video, check the phone bill and tell an adult if the call upset them. If a person answers any number from a list, apologise and hang up.

The ghost-story numbers: not dangerous, and where to find them

The legend numbers are mostly stories, not threats, so they are not the phone numbers you should never call for safety reasons. A few real lines among them, such as a real person's business line, are covered on their own pages, which say why we advise against calling them. Their stories are on our list of scary numbers to call: the devil's number, Sadako's number, the 20202020 legend, the Red Numbers panic, the Momo hoax, Thailand's wish number and clown phone lines.

The old suicide lifeline number

Some never-call lists include 1-800-273-8255 as a haunted curiosity. That was the number of the US National Suicide Prevention Lifeline before the three-digit 988 replaced it in July 2022; the 988 Lifeline has handled more than 17.5 million calls, texts and chats since launch (GAO). It has no legend and no place on an entertainment list. If you or someone near you needs help, call or text 988.
