Vietnamese Dong (VND) is one of the currencies with the most zeros in the world. While daunting at first, you'll soon notice a specific "rhythm" to how money is handled.

1. Dropping the "Thousand"

In markets and cafes, rarely does anyone use the full name of the numbers. Since the smallest common bills are 1,000 or 2,000 VND, the word "thousand" (nghìn/ngàn) is often dropped entirely.

  • If a coffee costs 25,000 VND, the waiter will simply say "Hai mươi lăm" (25). It is understood that "thousand" is implied.

2. The Southern "Chục" System

In Southern Vietnam, instead of saying 10 (mười), people often use Chục as a unit of ten.

  • Hai chục (Two tens) = 20
  • Năm chục (Five tens) = 50

3. Reading the Banknotes

Vietnamese notes are polymer and color-coded. A common beginner mistake is confusing the 20,000 VND (bright blue) with the 500,000 VND (cyan/blue). Always double-check before handing over the highest denomination.

Một trăm nghìn (100,000 VND): Green. It's roughly $4 USD. Use this as your mental baseline for a decent meal.
