Vietnam Currency Exchange: 100 Dollar Bill Rules and Damaged Note Fees

When exchanging US dollars for Vietnamese dong, local counters offer higher rates for crisp 100-dollar bills than for smaller denominations. Minor tears, ink marks, stamps, or dirt stains can cause note rejection or fee penalties, requiring thorough bill checks before travel.

This is the Currency Exchange and Payment Methods item for a trip to Southeast Asia. The 3 checkpoints below can only be settled properly before you leave — put them off and you queue at an airport desk or spend the first day on them instead. Work through them once and nothing has to be reopened.

Key checkpoints

Request uncirculated or recent-series 100-dollar bills from your bank and inspect both sides before leaving the teller counter.
Carry only undamaged notes without pinholes, pen marks, teller stamps, heavy creases, or water stains to avoid refusal at local exchange booths.
Prepare your primary travel funds entirely in 100-dollar bills because smaller 1, 5, 10, 20, and 50-dollar notes receive lower exchange rates.

What to do before departure, in order

Two rules decide the order. First, anything with a deadline — pre-registration, bookings, documents to be issued: miss the cut-off and there is no substitute. Then whatever also works locally, which costs little to postpone.

Most of the items above can only be done before you leave. After arrival, patchy connectivity and opening hours make them harder, so finish what you can while you are still at home.

What to pay attention to in Southeast Asia

Visa-free stay lengths and entry conditions differ country by country in Southeast Asia, so the region as a whole tells you nothing — check each country. A passport valid for at least six months is a frequent condition.

Tap water is not drinkable in many areas, so decide how you will get drinking water before you go.
