Beliefs & Spirituality
Ask anyone in Thailand for their lucky number and you will almost always hear the same answer: เก้า (gâo), nine. But Thai lucky numbers go well beyond nine. Eight, five and three all carry good fortune, six and thirteen are quietly avoided, and the choice of a lucky number in Thailand shapes everything from wedding dates and phone numbers to a record-breaking 45-million-baht licence plate. This guide explains every Thailand lucky number, the Thai words behind each belief, and how to use them like a local.
สวัสดีครับ (Sawasdee krab/ka)! Welcome to a fascinating aspect of Thai culture: the world of lucky numbers. Like many cultures, Thais often associate certain numbers with good fortune and prosperity, influencing everything from daily decisions to major life choices. Understanding these numerical beliefs offers a deeper insight into the Thai way of thinking.
One of the most prominent lucky numbers in Thailand is เก้า (gâo), which means "nine." The popularity of nine stems from its phonetic similarity to the word ก้าวหน้า (gâo nâa), meaning "to progress" or "to move forward." This auspicious association makes nine a highly sought-after number. You'll often see people trying to get phone numbers, car license plates, or even house numbers that contain multiple nines. It's believed that having this number around brings success and advancement in all aspects of life. For instance, a wedding held on the ninth day of the ninth month is considered exceptionally lucky for the couple's future together.
Nine's status was cemented by King Bhumibol Adulyadej (Rama IX), the ninth king of the Chakri dynasty, who reigned for seventy years. On 9 September 2009 at 9:09 a.m., people across the country paused for a nationwide tribute to him, and the numeral ๙ remains a shorthand for loyalty to the late king.
Nine also sets the rhythm of ceremonies. Thai families typically invite nine monks (พระ 9 รูป) to bless a new house, a wedding or a business opening, and gifts of 999 or 1,999 baht are a popular way to wish someone prosperity.
The clearest proof of nine's pulling power is the market for auspicious licence plates (ทะเบียนรถเลขสวย). In December 2022 the Department of Land Transport auctioned the Bangkok plate 9กก 9999 for 45.09 million baht, a national record, after 202 bids. It beat the 28.1 million baht paid for 8กก 8888 in 2020. Phone numbers get the same treatment: Thais call them เบอร์มงคล (ber mong-kon), auspicious numbers, and a SIM card packed with nines changes hands for many times its face value.
Another number that holds significant positive connotations is แปด (bpàet), meaning "eight." While perhaps not as universally celebrated as nine, eight is gaining popularity, partly due to its auspicious status in Chinese culture, which has a strong influence in Thailand. In Chinese, eight sounds like "fa," meaning "wealth" or "to prosper." This association has resonated with many Thais, especially in business dealings. You might find entrepreneurs preferring addresses or phone numbers with eights, hoping to attract financial success.
Five, ห้า (hâa), sounds exactly like a Thai laugh, which is why Thais type 555 to mean "hahaha" in chats and comments. That cheerful association makes five a favourite in phone numbers and lottery picks, and 555 is probably the first piece of Thai numerology every learner meets online.
Many Thais consider odd numbers luckier than even ones, and three, สาม (sǎam), is the classic auspicious pick. Buddhism gives it weight: the Triple Gem (พระรัตนตรัย) of the Buddha, his teaching and the monastic community is honoured with three prostrations, and incense sticks at a temple are usually lit in threes.
Conversely, there are numbers considered unlucky, with หก (hòk), meaning "six," often topping the list. The reason for this is quite interesting. When written in Thai script, the number six (๖) can resemble an inverted nine (๙). This visual similarity, combined with the belief that an inverted nine brings the opposite of progress, makes six a number many Thais try to avoid. You might hear people jokingly lamenting if they get a phone number with too many sixes. The word itself does not help either: หก (hòk) is also the verb "to spill" or "to fall over", so a number full of sixes sounds like a run of small accidents.
The number สิบสาม (sìp sǎam), or "thirteen," also carries negative connotations, largely due to Western influence. While not as deeply rooted in traditional Thai beliefs as the aversion to six, the global superstition surrounding thirteen has been adopted by many Thais, particularly in urban areas.
Four, สี่ (sìi), is a special case. In Thai it sounds nothing like the word for death (ตาย, dtaai), so most Thais are relaxed about it. Thai-Chinese families, however, often avoid it because four sounds like "death" in Chinese, which is one reason flats and plates numbered 4 or 13 can sell for less.
Nowhere are Thai lucky numbers taken more seriously than in the lottery, หวย (hǔay). The Government Lottery Office holds draws on the 1st and 16th of every month, and in the days before each draw the hunt for winning numbers becomes a national pastime. People read numbers from dreams, from the licence plates of cars in the news, from candle wax dripped into water at temples, and from the age of a revered monk.
These numerical beliefs are more than just superstitions; they are a part of the cultural fabric, offering comfort, hope, and sometimes even a bit of fun. Whether it's selecting a special date or choosing a new phone number, the search for เลขนำโชค (lêk nam chôk) – lucky numbers – adds an intriguing layer to daily life in Thailand.
So, the next time you're in Thailand, keep an eye out for these numerical preferences. You'll see how deeply ingrained they are in the culture, reflecting a desire for prosperity, progress, and good fortune.
What is the luckiest number in Thailand? Nine (เก้า, gâo). It sounds like ก้าว (gâao), "to step forward", and it is tied to the late King Rama IX.
Why do Thai people type 555? Five is ห้า (hâa), so 555 reads as "ha ha ha". It is the Thai way of writing "lol".
