Scams in Argentina (2026): Money Tricks and Street Crime to Avoid
TL;DR
Most things that go wrong for foreigners in Argentina are money tricks and petty theft, not violent crime. Never accept a transfer screenshot as proof, check that a QR sticker is not glued over another one and that the merchant name matches before paying, check large peso bills, avoid street money changers, never pay a rental deposit before viewing, and keep your phone off café tables. Emergency: 911; Tourist Police +54 9 11 5050-9260.
Buenos Aires is a safe city for most visitors. Violent crime against tourists is rare, and the things that actually go wrong are petty: a phone snatched from a café table, a fake bill handed back as change, a transfer screenshot that never turns into money. This guide covers both halves. The first part is the money and payment scams that most safety guides skip, which is what we see every day as a payments app. The second part is street crime, where we lean on the excellent Buenos Aires safety guide by Paul Perry at Gringos in Buenos Aires.
Keep the emergency numbers for Argentina saved on your phone before you need them.
Part 1: money and payment scams
1. The fake transfer receipt (comprobante trucho)
You sell something on Marketplace, rent out a room or hand over goods, and the buyer shows you a screenshot of a Mercado Pago or bank transfer. It looks perfect: your alias, the amount, a transaction number. It was edited, or the transfer was cancelled a minute later, and the money never arrives.
- Never accept a screenshot as proof. Open your own app and check that the money is in your balance before you hand anything over.
- Be wary of buyers who rush you, overpay "by mistake" and ask for the difference back, or send the receipt by WhatsApp from a number with no history.
2. The swapped QR sticker
QR payments are everywhere in Argentina, and so is a simple trick: someone sticks their own QR code over the real one on a café table, a parking meter or a market stall. You scan, pay, and the money lands in the scammer's account.
- Look at the sticker before you scan. A QR glued over another one, wrinkled or misaligned, is a red flag.
- Read the recipient name on the confirmation screen and compare it with the business you are standing in. In CacaoCash the merchant name is shown before you confirm the payment, so take two seconds to read it.
- A QR should take you to a payment, never to a web page asking for your card details or passwords.
3. Fake 10,000 and 20,000 peso bills
Counterfeit notes circulate, and the high denominations are the ones worth faking. They are usually passed in the dark: a taxi at night, a crowded bar, a street money changer. Check any big bill you receive with at least two of these:
- Touch. Real notes feel slightly rough in places. A bill that is too smooth, slippery or stiff is suspect.
- Watermark. Hold it to the light: the blank area shows the portrait (Alberdi on the 20,000) and the initials.
- Security thread. On the 10,000 it shows in three small windows on the front; on the 20,000 a blue band with "BCRA" appears against the light.
- Hidden image. Tilt the 10,000 and the letters "RA" appear in the lower right corner.
The simplest defence is to carry less cash. You can pay most shops, restaurants and even many taxis by QR, which is the point of an app like CacaoCash.
4. "Cambio, cambio": street money changers
On Calle Florida and around tourist areas, arbolitos call out "cambio, cambio" and offer to change your dollars. They often walk you to a back room or a gallery upstairs. The risks are fake bills, a rate that changes once you are inside, and being watched by someone who follows you out. If you must exchange cash, use an established exchange house recommended by people who live here, count the money in front of the cashier and check the big bills. Our guide to cuevas and where to exchange dollars explains how it works and why in 2026 you often get more by not exchanging at all.
5. P2P crypto and "send first" scams
Expat groups on Telegram and WhatsApp are full of people offering to swap USDT for pesos. The classic scam is simple: you send first, they block you. A variant uses a fake payment receipt so you release your crypto before their pesos have arrived.
- Never send first to a stranger. On an exchange's P2P market, keep the trade inside the platform's escrow and never release until the pesos are in your own account.
- Be suspicious of a rate that is clearly better than everyone else's. That is the bait.
6. Rental deposit scams
A beautiful apartment at a great price, an owner who is "abroad", and a request to transfer a deposit or a "reservation" before you can see it. Once you pay, the listing disappears.
- Do not pay anything before you have seen the place, in person or on a live video call where you control what you see.
- When you transfer to an alias, the app shows the account holder's name. Check that it matches the person or agency you signed with.

7. ATM tricks
Foreign cards work in Argentine ATMs but with high fees and low limits, and the ATM is where people are most distracted. Use machines inside bank branches during opening hours, cover the keypad, and ignore anyone who offers to help if the machine "eats" your card; go to the bank counter instead. The guide on withdrawing cash with low fees explains the cheaper options.
8. Fake support calls and messages
A message or call from "your bank", "Mercado Pago" or "app support" says there is a problem with your account and asks you to confirm a code, install an app or move your money to a "safe account". No real support team asks for your PIN, your password or a one-time code, and none will ask you to move money. Hang up, then contact the company through its official app or website.
9. Airport taxi touts
At Ezeiza and Aeroparque, drivers approach you in the arrivals hall offering a ride. Some charge several times the normal fare. Use the official taxi and transfer counters inside the terminal, where you pay a fixed price, or a ride-hailing app.
Part 2: street crime
This part draws on the safety guide at Gringos in Buenos Aires, written by Paul Perry, who has lived in the city since 1990. Their core rule is no te regalés: do not make yourself an easy target. Read their full guide for more detail.
- Motochorros. Thieves on motorbikes grab phones from people looking at a map on the curb or sitting at an outdoor table. Keep your phone off café tables and step into a doorway to check directions.
- The mustard trick. Someone squirts a smelly liquid on your back, a "helpful" stranger offers to clean it, and an accomplice takes your bag. Say no, do not stop, and walk into a shop.
- The taxi bill swap. You pay with a large note and the driver "discovers" it is fake, handing back a counterfeit instead of yours. Say the value out loud as you hand it over, or pay by QR or through an app like Cabify.
- Drink spiking. Reported mostly around dating apps. Do not leave drinks unattended and meet first dates in public places.
- Protests. Demonstrations near Congreso and Plaza de Mayo are frequent and can turn tense. Watch from a distance or take another route.
If it happens to you
- Get safe first. Call 911 for an emergency. For help in English, the Tourist Police (Comisaría del Turista) is at Av. Corrientes 436 and answers on +54 9 11 5050-9260, also on WhatsApp.
- Lock your money. If your phone was taken, contact your bank and every payment app you use from another device. For CacaoCash, write to info@cacaocash.com. Your CacaoCash app is protected by your PIN in the meantime.
- Block the phone. Ask your carrier to block the SIM and the phone's IMEI.
- File a police report (denuncia). You need it for insurance, for your embassy if your passport was stolen, and for any claim with a bank or app. Save screenshots, receipts and the recipient's alias.

Frequently Asked Questions
Is Buenos Aires safe for tourists?
Yes, for the most part. The main expat neighborhoods are fine for walking and eating out at night. The real risks are phone snatching, pickpocketing and money tricks, all of which you can reduce by keeping your phone out of sight on the street and carrying less cash.
Is it safe to pay with QR codes in Argentina?
Yes, as long as you check two things: that the QR sticker has not been placed over another one, and that the name on the confirmation screen matches the business. Paying by QR also means carrying less cash, which removes the fake bill problem entirely.
What should I do if I paid a fake QR?
Contact your payment app immediately with the date, amount and recipient shown in your history, then file a police report. Act fast: the sooner the receiving account is reported, the better the chance of freezing it.
How can I tell if a peso bill is fake?
Check touch, watermark, security thread and the hidden "RA" image on the 10,000. If a large bill feels wrong, do not accept it, and avoid exchanging cash with street changers in the first place.
