Walk into a high-rise in Hong Kong, Shanghai, or Taipei and look at the elevator panel. Floors jump from 3 to 5. Sometimes 13, 14, 24, and 34 vanish too. No signage explains it — everyone just knows. The reason why Chinese avoid the number 4 comes down to something surprisingly simple: sound.
The Phonetic Root of the Fear
In Mandarin, the word for four — sì (四) — sounds nearly identical to sǐ (死), the word for death. The tones differ slightly (fourth tone vs. third tone), but in fast speech, over a phone line, or across a noisy restaurant, the distinction blurs. In Cantonese, the overlap is even closer: sei means both four and death with almost no tonal separation at all.
This is called tetraphobia — a specific aversion to the number 4 — and it's one of the most widespread numerical superstitions on earth. It's not fringe belief. It shapes architecture, product pricing, phone number selection, hospital room assignments, and wedding dates across a billion-plus people.
How far back does this go?
Scholars trace the aversion at least to the Tang Dynasty (618–907 AD), though the superstition likely predates written records of it. The fear intensified as urbanization packed people into numbered apartments and telephone exchanges made four-digit strings part of daily life. Once numbers became personal identifiers, their phonetic weight mattered more than ever.
How Deep Does Tetraphobia Actually Run?
Deeper than most Westerners expect. Consider the practical ripple effects:
- Real estate: A study of property sales in Vancouver — a city with a large Chinese-speaking population — found that homes with street addresses ending in 4 sold for measurably less than comparable homes ending in 8. The discount was real and consistent.
- Aviation: Some Asian carriers have no Row 4, and a few have removed rows 14 and 44 from their cabin configurations entirely.
- Hospitals: In parts of Hong Kong and Taiwan, hospital wards skip room 4, floor 4, and sometimes any room number containing a 4.
- Product launches: Nokia famously skipped the 4 series in several Asian markets. Corporations adjust product numbering for China specifically — not as a courtesy, but because sales data backs it up.
- Phone numbers: A mobile number loaded with 4s is considered genuinely unlucky and can be hard to sell or transfer. A number like 444-4444 would be essentially worthless, or worse — a bad omen — in a Chinese business context.
The Numbers People Want Instead
You can't understand the avoidance of 4 without understanding what fills the space it leaves. Chinese numerology is as much about attraction as repulsion.
8 (bā / 八) is the star. It rhymes with fā (发), meaning to prosper or to get rich. The 2008 Beijing Olympics opened on 08/08/08 at 8:08 PM for this exact reason. A phone number ending in 888 or 8888 commands a significant premium — sometimes thousands of dollars.
6 (liù / 六) sounds like liù (流), associated with smooth flow and things going well. In business contexts, 666 reads as everything going smoothly — the opposite of its Western connotation.
9 (jiǔ / 九) rhymes with jiǔ (久), meaning long-lasting or eternal. Popular in wedding contexts for that reason.
1, 2, 3 are generally neutral. 5 can be iffy — it sounds like "not" in some contexts — but is mostly benign.
The number 4 combined with other numbers creates compound meanings. 514 can be read as "I will die." 748 can mean "go to hell." These combinations matter enormously in gifting, business cards, and especially phone numbers.
Why Phone Numbers Are Ground Zero for This Belief
A phone number is one of the most personal and repeated identifiers a person or business carries. You say it aloud. You hand it to clients. In Chinese culture, handing someone a business card with multiple 4s embedded in the number is, at minimum, bad form — and at worst, a serious insult.
This is why the premium phone number market in Chinese-speaking communities operates on numerological logic as much as mnemonic logic. A vanity number that's easy to remember but packed with 4s is still a bad number. A harder-to-memorize string that ends in 8888 is worth serious money.
A concrete example: A Cantonese-speaking restaurant owner in Los Angeles chose the local number 626-888-8828 over a simpler sequence because the 8s outweighed the mild awkwardness of the pattern. The number cost more. She considered it an investment in the business's perceived fortune — and her customers noticed it approvingly.
Does Younger or Western-Born Chinese Still Care?
Somewhat, yes — though with more variation. Third-generation Chinese-Americans often treat the number 4 with mild cultural awareness rather than active avoidance. But first- and second-generation immigrants, and virtually anyone doing business with mainland China, Taiwan, or Hong Kong, treat it seriously. Companies expanding into Chinese markets learn this fast.
The belief also travels. Japan has a parallel aversion — shi (四) in Japanese also means death — and tetraphobia shows up in Korean culture as well, where sa (사) carries the same phonetic baggage.
Quick Takeaways
- Why do Chinese avoid the number 4? It sounds like the word for death in both Mandarin and Cantonese.
- The aversion is called tetraphobia and has influenced Chinese culture for over a thousand years.
- It shows up concretely in building floors, hospital rooms, product lines, aircraft seating, and phone numbers.
- 8 is the preferred replacement — associated with wealth and prosperity.
- Combinations matter: 44, 444, and sequences like 514 carry compounded negative meaning.
- The belief is strongest among first-generation immigrants and in active business dealings with Chinese-speaking markets.
- Phone numbers with multiple 4s lose real monetary value in Chinese-speaking communities; numbers rich in 8s gain it.
If you're choosing a business or personal number for a Chinese-speaking audience — or simply want a number that carries the right weight culturally — browsing available options with this numerology in mind makes a real difference. You can search premium phone numbers on GreatNumber and filter by pattern to find combinations that work in your market.
