Haunted Numbers: The Cursed Digits People Still Avoid

About eighty percent of skyscrapers in America lack a thirteenth floor. Not because of superstitions of constructors. But because tenants simply do not want to live on it.

And this single fact says everything there is to say about the topic. No need to believe that a certain number is evil for it to affect city planning, and it is exactly what is happening right now with phone numbers, clock times and hospital rooms allocation across the world.

Where it all comes from, which traditions are much older than you would expect, and which should be taken seriously after all.

The short answer

There are three categories of ‘haunted’ numbers. First, there are digits considered unlucky in a certain culture. They are usually related to sounding similarly to the word for death in that particular language. Then, there are cursed phone numbers – basically a contemporary folklore and sometimes a fraud. Finally, there are clock times, mainly 3am and repeating digits, and they have little to do with numbers themselves but rather human psychology. None of them has any proven effect. All of them make people behave differently.

Why numbers get haunted in the first place

There are three factors responsible for almost all numbers on this list.

The first one is language. The number is considered evil if it is sounding similarly to some word that frightens people, and that is the reason why unlucky digits are completely different for every language. Four, for instance, is perfectly harmless. But there is a lot to be afraid of in it sounding exactly the way the word for death in several East Asian languages.

The second factor is religion and myths. It gives an explanation for a certain number and makes people discuss it during next few centuries even if most of them have forgotten the meaning.

The third factor is confirmation bias and plays its part mainly in modern cases. Once you know that you have to pay attention to some number, you see every time it is around and do not even notice any other number. You see 3:12 on the clock and do not think anything about it. 3:33 is stuck in your mind for years.

The unlucky numbers, country by country

Number	Where	Why
13	Much of the West	Judas as the thirteenth guest, plus Norse myth
4	China, Japan, Korea, Vietnam	Sounds almost identical to the word for death
9	Japan	Sounds like the word for suffering or agony
17	Italy	The Roman numeral rearranges to mean I have died
39	Afghanistan	Carries a strong local stigma and is avoided
666	Christian tradition	The number of the beast in Revelation
13	Not in Italy	There it is lucky. Seventeen carries the fear
8	China	The opposite. It sounds like prosperity and is prized

That last pair is the most useful thing in the table. A number cannot be inherently cursed if it is lucky one border away. Thirteen is fine in Italy and dreaded in America, four is unremarkable in Europe and removed from lift panels in Hong Kong. The fear is local to the language, every time.

Thirteen, and where it actually comes from

Both origins concern a dinner guest whose attendance numbers thirteen. In the Christian version, this is Judas as the thirteenth man at the Last Supper. In the Norse version, Loki crashes the party of the twelfth or thirteenth guest and kills a god. Debate rages as to whether the Norse origin story had anything to do with the Christian one, and neither can be traced reliably to the superstition’s origin.

The results are everywhere when you look for them. Skips the thirteenth floor? So do buildings. Skip row 13? So do airlines. Hotels don’t use 13, either. Apollo 13 launched at 13:13 Houston time and suffered an explosion on 13 April, which helped the superstition far better than a century of folk tales could ever hope to.

Something to be careful about. You will hear that the Code of Hammurabi omits the thirteenth law on purpose. Not true. The original has no numbering system whatsoever; the gap was created by a translator skipping a clause and numbering the remaining ones. The story persists because it is more colorful than the reality.

And as for Friday the 13th being the day of accidents, the research is a bit of a mess. One small British study from the 1990s claims to have detected more traffic accidents and garnered massive media attention. Further analyses show no effect, and at least one insurance study shows fewer traffic accidents, probably because a few people are too afraid of getting into an accident to go out.

The number that might not be 666

Revelation reveals the number of the beast, and Western culture ran with it for two thousand years. There is even a name for this phobia, which is longer than the number itself.

The problem lies in the text. Not every early manuscript of Revelation features the number 666. The oldest fragment of Revelation shows the number as 616 instead, and there has been an academic debate about which number was first written in the manuscripts for hundreds of years. The most common explanation states that the number is supposed to encode some name, spelled with Hebrew letters, and a slightly different spelling gives us the difference between 666 and 616.

Either way, this number has real-life effects. The United States changed the route of Route 666 to Route 491 in 2003, having suffered from years of complaints of sign theft and the road’s reputation. Buildings and phone exchanges avoid the sequence. A number that might simply be a variation on the original number has been affecting road planning for decades.

Cursed phone numbers

This is the modern take on the folklore, which uses the modern method of delivery.

The construction of this legend is always the same. Some number is revealed along with a warning that it should not be called, because it will bring something terrible to the caller during the set period of time. The footage of someone calling it and experiencing nothing unusual is then released. In some cases, the number is Japanese; the legend about this number dates back to the 1980s and links it to death, while the number itself consists mainly of fours, which is interesting as it doubles the digit.

All the difference between this type of folklore and the previous one is that there is an actual phone number at the other end of the line.

Why not to call the numbers on those lists

This is the information that the listicles tend to leave out, and this is the only truly practical thing on this page.

• Quite a few of the cursed phone numbers lead to a regular person. A household can be bombarded with thousands of calls because a number went viral.
• Some numbers are premium rate, and the cost of the call is the curse itself. International premium rate numbers can get really expensive really fast.
• Some are one-ring scams, and their goal is to make the caller ring back an expensive number, and this is a well-documented fraud scheme.
• Some have turned out to belong to legitimate businesses or even services that people require but became unusable due to prankster calls.
• Using your own phone to call means giving away your number.

Then, there is the case of Momo. This is the most obvious example of why you shouldn’t believe anything that involves calling a number.

An image, which was a sculpture by a Japanese artist meant for a gallery, was circulating along with a phone number. The panic followed and spread internationally. The news media took it seriously. The sculptor eventually destroyed his sculpture. Nothing supernatural happened to anyone, and a genuine artist’s work was destroyed by an urban legend involving a phone number.

The devil hour and why you wake at 3am

The belief that 3am is the hour when the supernatural is closest is modern, and the reasoning usually given is that it inverts three in the afternoon, traditionally the hour of Christ’s death. Horror cinema then did the rest. Once a handful of successful films put a clock on screen at 3:07 or 3:33, the idea was permanent.

The reason people genuinely do wake around then has nothing to do with any of it.

Sleep runs in cycles, and the later cycles of the night contain far more light sleep than the earlier ones. Brief wakings are a normal feature of that architecture and everybody has several a night. In the first half of the night you do not remember them. In the second half you surface far enough to notice, and cortisol is already climbing toward morning.

Then the loop closes. You check the clock, see 3-something, and remember it because you were expecting it. You never remember the nights you woke at 2:20. If this is happening to you a lot and the house feels wrong with it, the ordinary causes worth ruling out are more useful than the hour on the clock.

11:11 and angel numbers

The positive version of the same mechanism. People report seeing repeating digits constantly and read meaning into it.

The effect has a name. Once something is brought to your attention, you start noticing it everywhere, and the sudden apparent increase feels like the world responding rather than your filter changing. A digital clock displays a repeating time a handful of times a day out of well over a thousand possible minutes, and you will glance at it dozens of times without registering a single ordinary one.

Worth saying plainly that this is harmless, and that people who find comfort in it are not doing anything worse than reading tea leaves. It only becomes a problem when someone starts making decisions on it.

Numbers that really do have a body count

Two cases where the coincidence is genuinely strange and worth knowing about.

Flight 191 is the good one. An American Airlines flight numbered 191 crashed in 1979 with no survivors among those aboard, the worst aviation accident on US soil. A Delta flight numbered 191 crashed in 1985. A Comair flight numbered 5191 crashed in 2006. Several airlines have retired the number. The rational reading is that there are only so many flight numbers and a great many flights, so clusters will occur. The irrational reading is difficult to shake once somebody has laid the three out in front of you.

Room 217 at the Stanley Hotel in Colorado is the other, and it works in reverse. The room did not have a reputation until Stephen King stayed in it and wrote The Shining, after which it became the most requested room in the building. A number acquired its haunting from a novel. That hotel sits on our list of the most haunted places in the world largely because of it.

The 27 Club deserves a mention as the famous one that does not hold up. The idea that musicians die unusually often at twenty-seven has been tested, and the analysis found no spike at that age. Musicians do die young more often than the general population. They just do not concentrate at twenty-seven, and the club is a list assembled backwards from a conclusion.

So are any numbers actually cursed

No. There isn’t any way in which a number would do anything to the world, but the most convincing proof is that the scary numbers depend entirely on what language one happens to speak at any given time.

What’s real is the effect that the number has, because there are buildings built without a thirteenth floor, flights cancelled, hospitals in several nations with rooms numbered differently because of the syllables, and people losing their money and sanity calling some phone numbers for a dare. The truth doesn’t have to exist in order for a belief to radically change the cityscape.

The most fascinating aspect about haunted numbers is that this topic is actually the other way around from how it sounds from the outside. This isn’t a story about numbers acting up. It’s a very clear indication of what a lot of people are ready to avoid without any proof whatsoever.
