Every "Vietnam scams to avoid" article reads like it was assembled by someone who has never been, copying a forum thread from 2012. They lump a 20-cent overcharge in with violent robbery and leave you nervous about the wrong things. The truth is more boring and more useful: Vietnam is a low-violence, high-overcharge country. You are very unlikely to be hurt and quite likely to be gently overcharged, and the entire game is knowing which is which.
Here is the honest ranking — most common first — with the one move that defuses each.
Tier 1 — you will probably encounter these
These are routine. Not malicious, mostly, but they add up.
The taxi that won't use the meter
The single most common one. A taxi (especially outside the two reputable brands, Mai Linh and Vinasun) either has a "broken" meter, a meter that runs at triple speed, or quotes a flat fare four times the real price.
The move: Use Grab. It is the entire answer to this scam — the price is fixed in-app before you get in, and there is nothing to argue about. If you must take a street taxi, only Mai Linh (green) or Vinasun (white), and say "bật đồng hồ" — turn on the meter — before you move. See the phrasebook for the transport phrases.
Bill padding at restaurants and bars
Items you didn't order appear on the bill. The wet towel and the peanuts on the table are charged (often legitimately — they're not free, this one is half a misunderstanding). Or the per-item price quietly doubles from the menu.
The move: Check the menu price before ordering, glance at the bill before paying, and don't be shy about querying a line. In tourist-bar zones (Bui Vien in Saigon, parts of the Hanoi Old Quarter) assume the bill needs a look.
The "no change" routine
You pay with a 500,000đ note, the vendor claims to have no change, and either pockets the difference or sends a kid to "get change" who takes a while. Vietnamese dong runs into the hundreds of thousands and the notes look alike, which the scam relies on.
The move: Carry small notes. Break big notes at convenience stores (Circle K, WinMart) and keep 10k–50k notes for street stalls. Learn the note colours — the 20k (blue) and 500k (teal) look similar in a hurry.
Tier 2 — common in specific places
You'll hit these if you walk through the wrong street, but they're avoidable.
The motorbike rental "damage" scam
You return a rented scooter and the shop points to a scratch — that was already there — and demands a few million dong, holding your passport as leverage.
The move: Photograph and video the entire bike with the renter watching before you ride off. Never hand over your physical passport as a deposit — offer a cash deposit or a photocopy. If you're renting for the Ha Giang loop, this matters double; our motorbike licensing note covers the legal side.
The friendly shoe-shine / coconut-yoke photo
In the backpacker districts, a man insists on re-gluing your perfectly fine sandals, then demands a fortune. Or a woman drops her coconut-carrying yoke on your shoulder, snaps a photo, sells you the fruit at ten times the price, and won't take it back.
The move: A firm "không, cảm ơn" and keep walking. Don't let anything be put on your body or taken from your feet. This is almost entirely confined to Hanoi's Old Quarter and Saigon's District 1 — it does not happen in the countryside.
Tour-desk impersonation ("Sinh Tourist", "the real one")
A famous open-tour brand (Sinh Tourist) has been so widely cloned that there are dozens of near-identical shopfronts with the same name in different fonts. You book a bus through a fake one and get a worse bus, or no bus.
The move: Book transport and tours through your accommodation or a known app, not a random shopfront. For the regions we cover, book operators directly — that's the whole point of our operator comparisons.
Tier 3 — real but rare, or overhyped
Worth knowing, not worth losing sleep over.
- ATM card skimming. Real but uncommon. Use ATMs attached to actual banks (inside or in the lobby), prefer machines from major banks, and cover the keypad. Tip: many Vietnamese ATMs charge high fees and cap withdrawals — see the money section of the first-day setup.
- The "closed attraction" detour. A driver tells you the temple/museum is closed and offers to take you somewhere better (a shop he gets commission from). Just check opening hours yourself and decline.
- Fake "monks" selling blessings/bracelets. A minor nuisance near a few tourist temples. Real monks do not chase you down a street for money.
- Romance / overfriendly "student wants to practice English" leading to an expensive bar tab. Rare, mostly a Saigon-nightlife thing. If a stranger steers you to a specific bar, that's the tell.
What you can stop worrying about
The internet will tell you to fear things that, in practice, almost never happen to travelers in Vietnam:
- Violent mugging. Very rare. Petty bag-snatching from motorbikes happens in Saigon — keep your phone off the table at street cafés and your bag on the inside shoulder — but violence against tourists is genuinely uncommon.
- Drink spiking. Not a notable Vietnam problem the way it is in some party destinations. Normal sensible-drinking caution applies, nothing special.
- Police shakedowns of tourists. Traffic police may stop riders without a valid licence (a real risk — read the licensing note), but they are not generally shaking down pedestrians for bribes.
The one principle that covers 90% of it
Almost every Vietnam "scam" is a pricing scam, not a safety threat, and almost every pricing scam dies the moment the price is agreed before the transaction. Fix the price first — in the app, on the meter, on the menu, in your hand — and the leverage disappears. Smile, carry small notes, use Grab, and keep your passport in your pocket. That's the entire defence.
