Scams and Overcharging in Vietnam: How They Actually Work

Reviewed August 2026

28 min read·Updated Aug 2026

Vietnam is not a dangerous country for visitors, and it is worth saying that plainly before anything else. Violent crime against tourists is rare, most people you deal with are straightforward, and the overwhelming majority of trips involve nothing worse than paying slightly over the odds for a taxi.

What Vietnam does have — like every heavily-visited country — is a set of predictable commercial set-ups aimed at people who do not know the normal price of things and are unlikely to still be in town tomorrow. Almost none of them are dangerous. Almost all of them are annoying, and almost all of them are avoidable once you can recognise the shape.

This guide describes the patterns rather than accusing anyone. It also includes a section on what is not a scam, because a lot of advice online treats ordinary local pricing as fraud, and that gets travellers behaving badly toward people who have done nothing wrong.

The thirty-second version

  • Nearly every set-up depends on one of two things: you not knowing the normal price, or you being under time pressure. Remove those and most of this disappears.
  • Establish a price benchmark on day one. Ask your accommodation what a taxi to the places you plan to go should cost. That single answer protects you all week.
  • Use ride-hailing where you can. A price fixed in an app before you get in removes the entire category of transport dispute.
  • Count your change, and count the zeros. The 20,000 and 500,000 notes are both blue.
  • Never accept an unsolicited service. If someone starts cleaning your shoe or putting a bracelet on your wrist, that is the transaction beginning, not a kindness.
  • Agree the price before anything happens. Rides, tours, seafood by weight, repairs. Before, not during.
  • Do not hand over your passport as a deposit for anything.
  • If it goes wrong, decide fast whether it is worth the fight. Usually it is a few dollars and your afternoon is worth more.

Hoi An at dusk. Worth restating: Vietnam is not a dangerous country for visitors, and most trips involve nothing worse than an overpriced taxi.

The mindset that protects you, and the one that ruins the trip

There are two failure modes here and the second one is more common than people admit.

The first is naivety: assuming every price quoted is the real price and every helpful stranger is being helpful. That costs you money.

The second is corrosive suspicion: treating everyone as a potential thief, haggling aggressively over sums that are trivial to you and meaningful to them, and reading ordinary commerce as an attack. That costs you the trip. It also makes you unpleasant to deal with, and it is based on a false premise, because most people in Vietnam are simply doing their job.

The useful middle position is unglamorous: know what things cost, agree prices in advance, and then relax. Preparation replaces vigilance. A traveller who knows the benchmark fare does not need to be suspicious of the driver, because they will notice a bad number without looking for one.

One practical framing that helps: most of what follows is not theft, it is price discrimination against people who cannot tell. That is a commercial problem with a commercial solution — information — rather than a moral drama.

The two things every set-up depends onAlmost every overcharging set-up relies on the visitor not knowing the normal price of something, or being under time pressure. Removing either one defeats most of them. Ask your accommodation what a taxi should cost, and agree prices before anything begins.Every set-up depends on one of two thingsRemove them and most of this disappearsYou do not know the priceNo benchmark means any numbersounds plausible.Defeated by: one question at your hotelYou are under time pressureTired, arriving, hurried, or alreadymid-transaction.Defeated by: agreeing prices BEFOREThe reframe that helpsMost of this is not theft.

Preparation replaces vigilance. Someone who knows the benchmark fare does not need to be suspicious of the driver, because they will notice a bad number without looking for one.

Taxis: the single most common problem

If you have one bad transaction in Vietnam it will probably involve a taxi, and it will probably be at an airport or a station.

The recurring versions:

  • No meter, vague fare. A price is agreed loosely or not at all, then inflated on arrival, sometimes with a claim you misheard.
  • A meter that runs fast. Rarer than the internet suggests but it does happen, particularly with unmarked cars and knock-off liveries imitating established companies.
  • The scenic detour. A longer route than needed. Hard to detect without a map, trivial to detect with one running on your phone.
  • “No change.” You hand over a large note, the driver has nothing smaller, and the difference quietly becomes a tip. Sometimes genuine, often not.
  • The wrong-hotel redirect. Your hotel is “closed”, “full”, or “bad”, and the driver knows a better one — which pays him a commission.
  • The zero problem. A fare of 100,000 becomes a claim that you agreed 500,000, exploiting exactly the note confusion described below.

What actually works, in order:

  1. Ride-hailing. Grab dominates in Vietnam and the fare is fixed in the app before you get in. No negotiation, no meter, a record of the trip and the driver. This solves the problem rather than managing it.
  2. Established metered companies from an official rank. Confirm the meter is on and zeroed as you pull away. Be alert to liveries that closely imitate a well-known company’s branding.
  3. Agree a fixed price in advance, out loud, in writing on a phone screen if there is any language gap. Write the number down. This is where the zeros matter.
  4. Carry small notes so “no change” cannot happen to you.
  5. Have the route open on your own phone. Not to police the driver, but so you would notice.

And the structural fix: ask your hotel what the fare should be before you travel. Ten seconds of conversation converts you from an easy mark into someone who knows the number.

Taxi problems and fixesRecurring methods are an unmetered vague fare, a fast meter, a scenic detour, a no change claim, a wrong hotel redirect and exploiting the zeros. Fixes are ride-hailing with the fare fixed in the app, established metered companies from official ranks, agreeing a written price, carrying small notes and having the route on your own phone.Taxis: the single most common problemLeft: how it happens.

If you have one bad transaction in Vietnam it will probably involve a taxi at an airport or station. Ride-hailing removes almost the whole category.

The banknote problem, weaponised

Vietnam’s 20,000 and 500,000 dong notes are both predominantly blue, and the 500,000 is twenty-five times the value. That similarity produces honest mistakes in both directions every day. It also creates an opening.

The versions to know:

  • Change given in 20,000s where 500,000s were due, handed over quickly in a folded wad while you are being hurried along.
  • The swap. You hand over a 500,000, the recipient produces a 20,000 and says that is what you gave them. Nearly impossible to disprove after the fact.
  • The zeros in a spoken price. “Fifty” meaning 50,000 becoming a demand for 500,000.

The defences are boring and completely effective:

  • Count the zeros, not the colour. Five zeros after the five is 500,000.
  • Keep 500,000 notes physically separate in your wallet from day one.
  • Pay with small notes where you can, so there is nothing to swap.
  • Say the number out loud as you hand it over, and count your change in front of the person before you walk away.
  • Break large notes at supermarkets and hotels, not at street stalls.

Our guide to money in Vietnam has the full denomination breakdown and the ATM fee structure, both of which matter here.

The blue-note problem weaponisedThe 20,000 and 500,000 dong notes are both blue and the larger is 25 times the value. Change may be given in 20,000s where 500,000s were due, a note handed over may be swapped, or a spoken price may gain a zero. Count the zeros, keep large notes separate, pay in small notes, say the number aloud and count change before walking away.The blue notes, weaponisedHonest mistakes happen daily.

Rental damage claims

Renting a motorbike or scooter is where the largest single sums get disputed, because the claim is not five dollars — it is a few hundred for a scratched panel that may or may not have been there when you took the keys.

The pattern: you return the bike, the operator finds damage, and there is no agreed record of the bike’s condition beforehand. If they are also holding your passport, you are negotiating from a position of no leverage at all.

Two habits eliminate this almost entirely:

  • Do not leave your passport as a deposit. Offer cash, or a photocopy. A shop that will accept no alternative is telling you how disputes there get settled.
  • Film the bike before you ride away, slowly, with the staff present, capturing every existing scratch plus the odometer and fuel gauge. A timestamped video ends the conversation in seconds.

Our Vietnam motorbike guide covers the rest of the rental process, including the licence and insurance questions that matter far more than a scratched panel.

Tour bait-and-switch

This is the one that ruins a day rather than costing a few dollars, and it clusters around a small number of heavily-sold products — most notoriously the budget Ha Long Bay overnight cruise.

The shape: a very cheap headline price, booked through a street agency, delivers a boat that is materially not the one in the photographs, with a shorter itinerary, a shared cabin instead of a private one, and a series of on-board extras that were implied to be included. Kayaking is suddenly separate. Drinking water is charged. The “private balcony” is a shared deck.

How to avoid it:

  • Treat a price far below everything comparable as information, not a bargain. Boats cost what they cost to run.
  • Get the specifics in writing before paying: the vessel name, exactly what meals and activities are included, cabin type, group size, and the pickup and return times.
  • Book through your accommodation or an operator with a traceable reputation rather than a shopfront on a tourist street. Your hotel has an ongoing relationship with you and a reason to care.
  • Pay by card where possible, or pay a deposit rather than the full amount in cash up front. A card payment gives you a dispute route; cash gives you none.
  • Photograph the printed itinerary and receipt.

The same logic applies to trekking in the north, Mekong Delta day trips and canyoning around Da Lat: the cheapest version of an activity that requires equipment and staff is cheap for a reason, and with adventure activities the reason can matter for your safety rather than just your wallet.

Street set-ups: the unsolicited service

A family of small incidents share one structure: someone begins providing a service you did not ask for, and the price appears afterwards.

  • Shoe repair and shoe-shine. Someone points out that your shoe is damaged, takes it, does something to it, and names a price. Sometimes they created the damage.
  • The bracelet or trinket. An item is placed in your hand or tied to your wrist as a “gift”, then payment is requested. Returning it becomes awkward by design.
  • The conical hat and fruit basket photo. A vendor cheerfully places their hat on you and their basket on your shoulder, someone takes a lovely photo, and then there is a fee. This one is genuinely charming right up until the invoice.
  • The unrequested guide. Someone attaches themselves at a site, narrates, and requests payment.
  • Cyclo rides that change price. An agreed short ride becomes longer, or the per-person price becomes per-person-per-hour.

The single defence is to decline before it starts, clearly and pleasantly, and to keep walking. Once the service has begun you are in a negotiation. A firm “no, thank you” without breaking stride is not rude; it is the normal way city residents everywhere handle street commerce.

If you do want the photo — and it is a nice photo — agree the price first. Then it is a fair transaction and everybody is happy.

Every item here has the same shape, which is what makes the family easy to recognise once you have seen it named.

Restaurants and menus

Eating in Vietnam is one of the great pleasures of travel and overwhelmingly good value. The small number of places that overcharge visitors do it in recognisable ways.

  • No prices on the menu. The single biggest signal. If there are no prices, the price is whatever they decide when you have finished eating. Ask before ordering, or leave.
  • Seafood sold by weight. Legitimate everywhere in the world and also the most common overcharging mechanism in coastal restaurants. Agree the price per unit weight and confirm the approximate weight of the specific item before it is cooked. “Market price” with no number is not a price.
  • Unordered extras. Peanuts, wet towels, fruit, tissues and side dishes arrive unrequested and appear on the bill. Often trivial amounts, occasionally not. If you do not want them, hand them back unopened straight away.
  • The bill that does not match. Check the arithmetic and check for items you did not order. Do this without drama — genuine mistakes happen in busy kitchens.
  • Rounding up on change. Small and frequent. Carrying small notes is the fix.

The reliable heuristic: eat where the prices are written down and where local people are eating. Street food stalls with a visible price board and a queue of Vietnamese customers are simultaneously the best food and the least likely to overcharge you, because they are not built around one-off visitors.

Restaurant red flagsNo prices on the menu is the biggest signal. Seafood by weight is the most common mechanism, so agree the price per unit weight and the weight of the item before cooking.

Money changing and ATMs

Three things to watch, only one of which is really a scam.

Exchange counter sleight of hand. A rate is advertised, a different one is applied, or a “commission” appears at the end. Count the money you receive before leaving the counter and check it against the rate you were quoted. Use banks and licensed counters rather than a shop that happens to also change money.

Dynamic currency conversion. When an ATM or card terminal offers to bill you in your home currency rather than dong, that is not a convenience — it hands the exchange rate to the local operator at a margin in their favour. Always choose dong. This is legal, disclosed, ubiquitous and costs travellers more in aggregate than every street scam in this guide combined.

Card skimming. Rare but not absent. Prefer ATMs physically attached to a bank branch during opening hours, cover the keypad, and check your statements while you travel rather than after. If a machine looks tampered with or the card slot has any play in it, use another.

Money changing risksCount money received at an exchange counter against the quoted rate. Always choose to be billed in dong rather than your home currency, because dynamic currency conversion hands the rate to the local operator. Prefer ATMs attached to bank branches, cover the keypad, and check statements while travelling.Money changing and ATMsThree things to watch — only one is really a scam1Exchange counter sleight of handA rate advertised, a different one applied, or a “commission” at the end.

Dynamic currency conversion is the quiet one: entirely legal, fully disclosed, and it takes more from travellers than anything else on this page.

Tickets and “official” offices

Around bus stations, train stations and popular attractions you will find offices that look official and are simply agencies, plus individuals who offer to sell you a ticket you could buy at the counter for less.

The countermeasure is to buy from the actual counter or the actual operator’s own website. For trains, Vietnam Railways sells directly through its official site; third-party resellers are legitimate convenience services that add a fee, which is a fair trade as long as you know you are paying it. Our Vietnam by train guide covers that in detail.

Also be alert to closed-for-a-special-ceremony claims at temples and attractions, delivered by someone who then offers an alternative destination. Check the site’s actual opening hours yourself and walk to the entrance to look.

What is NOT a scam

This section matters as much as the rest, because a lot of online advice encourages travellers to treat normal commerce as fraud, and then to be rude to people over very small amounts of money.

  • Bargaining at markets. Negotiating is the expected form of the transaction at market stalls. A first price above what you will pay is not dishonesty; it is the opening of a normal conversation. Being asked a high number is not being cheated.
  • Different prices for tourists and locals at some attractions and on some transport. Two-tier pricing is an explicit, published policy in many countries. You may think it unfair; it is not deception.
  • Service charges and VAT added to a bill in a mid-range or upmarket restaurant, where they are stated on the menu.
  • A slightly higher price at a tourist-facing business. Rent is higher on the tourist street. So are prices. That is economics.
  • Tipping requests in tourist-facing service. Not traditional in Vietnam and never obligatory, but being offered the opportunity is not a con.
  • Card surcharges at small vendors, usually disclosed, covering a real processing cost.
  • “No change” that is genuine. A street vendor at eight in the morning may honestly not have change for a 500,000 note. Carry small notes and the situation never arises.

Getting this distinction right is not just about fairness to the people you meet. Travellers who treat everything as a scam make bad decisions — they avoid the street food that is the best thing about the country, and they spend their energy on the wrong risks.

A lot of online advice encourages travellers to treat ordinary commerce as fraud, and then to be rude to people over amounts that are trivial to them and meaningful to the seller.

If it happens anyway

At some point something will cost more than it should. The question is what to do about it, and the honest answer usually involves arithmetic rather than principle.

First, work out the actual amount. Convert it. A great many disputes travellers describe as infuriating turn out to be three or four dollars. If that is the figure, pay it and go and enjoy your afternoon — the alternative is spending an hour of a limited holiday on a matter of principle, in a language you do not speak, and arriving at your next destination angry.

If it is a meaningful sum, then:

  1. Stay calm and stay in public. Do not follow anyone anywhere. Volume never improves the outcome and can escalate a commercial disagreement into something worse.
  2. State the agreed price once, plainly, and offer that amount. Written evidence — the photo of the itinerary, the number you wrote on your phone, the timestamped video — is what actually resolves these.
  3. Involve your accommodation. This is the most under-used and most effective move available to you. Hotel staff speak the language, know local norms, know what things cost, and have a professional interest in your trip going well. For a tour dispute, they are far more useful than any official.
  4. Pay by card where a card was used, and raise a dispute with your bank when you get home if the service delivered was materially not the service sold. Keep every receipt and photograph. This is the main practical reason to prefer cards for larger purchases like tours.
  5. For anything involving theft, threats or a substantial sum, report it to the police and get a written report — you will need one for any insurance claim. Larger tourist centres have dedicated tourist police, and your accommodation will know where to go.
  6. Contact your embassy only for genuinely serious matters — a lost passport, an arrest, a hospitalisation. They cannot recover an overpriced taxi fare.

And a note on physical safety, since it belongs here: the realistic risk in Vietnamese cities is not being defrauded but bag and phone snatching from passing motorbikes. Do not walk along a road holding your phone out, do not wear a bag on the traffic side, and put the phone away before you step outside. That advice will do more for you than everything else on this page.

If it happens anywayWork out the real amount first. If it is a few dollars, pay and move on. If it is significant, stay calm and in public, state the agreed price once with your written evidence, involve your accommodation, and use a card dispute if a card was used. Report theft or threats to the police for the written report an insurer will need.If it happens anywayThe honest answer involves arithmetic, not principleA FEW DOLLARS?Pay it and go and enjoy yourafternoon.An hour of a limited holiday is worth moreA MEANINGFUL SUM?Work through the steps below,in order.Written evidence is what actually resolves these1Stay calm and stay in publicDo not follow anyone anywhere.

Frequently asked questions

Is Vietnam safe for tourists?

Yes. Violent crime against visitors is rare and most trips involve nothing worse than an overpriced taxi. The realistic risks are opportunistic phone and bag snatching in cities, and road traffic. Neither should stop you going.

What is the most common scam in Vietnam?

Taxi overcharging, by a wide margin, and most often at airports and stations. Ride-hailing with the fare fixed in the app removes almost the entire category.

Why do the 20,000 and 500,000 dong notes look so similar?

Both are predominantly blue polymer notes of similar tone, and the 500,000 is twenty-five times the value. Count the zeros rather than reading the colour, and keep the large notes physically separate in your wallet.

Should I use Grab in Vietnam?

Where it is available, yes. The price is fixed before you get in, there is a record of the trip and the driver, and there is nothing to negotiate. It is the single most effective anti-overcharging tool available to a visitor.

Are cheap Ha Long Bay cruises a scam?

Not inherently, but a price far below everything comparable is information rather than a bargain. Get the vessel name, inclusions, cabin type and timings in writing before paying, book through your accommodation or a traceable operator, and pay by card if you can.

Is it rude to bargain in Vietnam?

At market stalls, no — negotiating is the expected form of the transaction. In shops with marked prices, restaurants and supermarkets, prices are fixed and haggling is out of place. And keep it proportionate: pushing hard over an amount that is trivial to you and meaningful to the seller is not a win.

Should I ever hand over my passport as a deposit?

No. Offer a cash deposit or a photocopy. Your passport is the document you need for hotels, domestic flights, banking and departure, and handing it over gives the other party leverage in any dispute.

What should I do if a driver demands more than the agreed fare?

Work out the real amount first. If it is a few dollars, pay it and move on. If it is significant, stay calm and in public, state the agreed price once, offer that, and involve your accommodation rather than escalating on the street.

The short version

Two things do almost all the work. Know what things cost — ask your accommodation on day one what a taxi to your planned destinations should be, and you have a benchmark for the whole trip. And agree prices before anything happens, whether that is a ride, a tour, a repair or a kilo of prawns.

After that: use ride-hailing, carry small notes, count the zeros, decline unsolicited services before they start, keep your passport in your pocket, and put your phone away on the street. That is the entire defence, and none of it requires being suspicious of anyone.

Then stop worrying about it. The overwhelming majority of people you deal with in Vietnam are honest, the food is extraordinary, and the worst realistic outcome of a relaxed trip is that you occasionally pay a dollar or two more than a local would. That is a perfectly acceptable price for not spending your holiday on guard.

Next: money in Vietnam covers notes, ATMs and card acceptance, arriving in Vietnam covers the airport transfer where most of this starts, the motorbike guide covers rental deposits and damage claims, and is Vietnam safe covers the wider safety picture.
