Vietnamese lucky numbers — 39, 79 and the god of fortune
The meaning of Than Tai, why 39 and 79 close a phone number with fortune, and the numbers Vietnamese-Australian buyers ask for most.
Vietnamese-Australians are one of the largest Asian communities in the country, concentrated around Cabramatta, Springvale, Inala and Marrickville. Vietnamese number culture blends deep Chinese influence with distinctly local homophones — and produces some of the most specific mobile-number preferences you'll see anywhere in the world.
Than Tai — the god of fortune, and the number 39
Vietnamese folklore honours Than Tai, the god of wealth. His feast day falls on the 10th day of the Lunar New Year, and shop owners across Vietnam make offerings that morning to ensure a prosperous year. The number most associated with Than Tai is 39, and it appears everywhere: number plates, addresses, and — especially — mobile numbers.
In practical terms, a number ending in 39 or 79 (also read as a Than Tai closer) is regarded as finishing on a note of luck. This is why Vietnamese buyers will pay a real premium for endings like 04XX XXX 3939 or 04XX XXX 7979.
The core digits
- 9 (chin) — the pinnacle. Highest single digit, ideas of long life and success.
- 8 (tam) — inherits the Chinese "phat" (prosper) meaning; still highly favoured.
- 6 (sau) — "loc" (fortune, blessings from ancestors).
- 3 (ba) — associated with Tam Tài (Heaven, Earth, Human) and with Than Tai.
- 7 (bay) — a "runner up" to 9, and pairs with 9 in Than Tai combinations.
The numbers to be careful with
- 4 (tu) — read like the Chinese sǐ, "death". Some younger buyers are less superstitious, but for most Vietnamese families numbers heavy in 4 are avoided.
- 13 — a Western superstition that has been widely absorbed and is often avoided.
Combinations that carry real value
- 3939 / 7979 — "double Than Tai" endings. Among the most requested.
- 6868 — "loc phat loc phat", fortune and prosperity, repeated.
- 8686 — same idea in reverse; the ABABAB pattern is highly valued.
- 1368 / 1368… — "một đời phat loc", a lifetime of fortune.
- Six-repeat 9 or 8 — the "must-have" for a business owner who can afford it.
Ngu Quy — the "five noble" pattern
Vietnamese collectors use the term Ngu Quy ("five nobles") for a mobile number ending in five of the same digit (AAAAA). Ngu Quy 9 — ending in 99999 — is considered the strongest run outside of a full six-repeat. Our AAAAA category is essentially the Ngu Quy shelf.
