Here's a fact that surprises most first-time visitors: the majority of negative incidents reported by tourists in Buenos Aires are scams, not violent crime. Someone loses money or a phone through a clever trick, not through confrontation. The good news is that once you know how these tricks work, they become almost impossible to fall for — because they all rely on the element of surprise.
Here are the classic scams targeting tourists in Buenos Aires, and exactly how to shut each one down.
The mustard (or ketchup) trick
How it works: Someone — often two people working together — "accidentally" spills mustard, ketchup, or bird droppings (sometimes fake) on your clothes or bag. A stranger immediately appears to help clean it up, using the physical contact and distraction to go through your bags or pockets.
How to avoid it: If anything unexpected lands on you in the street, do not accept help from anyone nearby. Keep your bag pressed against your body, walk directly into a shop or hotel, and clean up there. This is one of the oldest tourist scams worldwide and Buenos Aires is not an exception.
The fake taxi meter
How it works: A street-hailed taxi (not a rideshare app) has a rigged or manually manipulated meter that runs faster than it should, or the driver simply quotes an inflated fixed price for a short trip, counting on the tourist not knowing the normal fare.
How to avoid it: Use a rideshare app (Uber, Cabify, DiDi) instead of hailing taxis on the street. The fare is fixed and shown before you even get in the car, which eliminates this entire category of risk. If you must use a street taxi, official radio-dispatched taxis are more reliable than ones hailed randomly.
Counterfeit bills in change
How it works: When paying in cash — especially with large bills — you may receive counterfeit notes in your change, particularly in informal exchange transactions or from unlicensed street vendors.
How to avoid it: Exchange money only through your bank, hotel, or licensed exchange houses (casas de cambio). When paying with cash for larger amounts, use card whenever possible — most established businesses in tourist areas accept cards.

Chat with us on WhatsAppThe "helpful stranger" at the ATM
How it works: Someone nearby offers unsolicited help when your card gets stuck, the machine seems confusing, or you appear to be struggling — and either distracts you while an accomplice takes your card, or memorizes your PIN over your shoulder.
How to avoid it: Use ATMs inside banks or shopping malls during business hours, cover the keypad with your free hand while entering your PIN, and never accept unsolicited help from a stranger at a cash machine.
Fake plainclothes "police" or "officials"
How it works: Someone claiming to be a police officer or immigration official approaches, often requesting to see your documents or wallet "for verification" — sometimes with a fake badge shown briefly.
How to avoid it: Genuine police in Argentina do not typically demand to inspect a tourist's wallet or cash on the street. If approached, ask to see clear identification, and if anything feels off, state that you'll go with them to the nearest official police station rather than handing over documents or money on the spot.
The distraction theft (multiple accomplices)
How it works: A group works together — one distracts you (asking for directions, offering a flyer, staging a minor commotion) while another takes an unattended bag or phone.
How to avoid it: Stay aware in crowded areas — public transport stations, popular tourist landmarks, busy markets. Keep bags in front of your body rather than on your back, and phones in a zipped pocket rather than in hand while walking.
Overpriced "official" tourist services
How it works: Unofficial "guides" or vendors near major landmarks offer tours, tickets or services at inflated prices, sometimes implying they're the only or official option.
How to avoid it: Book tours and tickets through your hotel, a recognized agency, or official websites. If someone approaches you unsolicited claiming to be the "only" way to access something, that claim is almost always false.
The pattern behind every scam on this list
Notice what all seven have in common: they rely on distraction, urgency, or unsolicited "help." Once you recognize that pattern, the specific trick almost doesn't matter — the defense is the same: slow down, decline unsolicited help, and move to a safe, populated space before deciding what to do next.
Conclusion
None of these scams involve real danger — they're financially motivated and rely entirely on catching you off guard. Reading this list is, in itself, most of the protection you need: awareness removes the surprise, and surprise is the only tool these tricks actually have.
