Mercado Pago Fraud: How to Report It and Stop the Money
If you sent money to a scammer through Mercado Pago, or money left your Mercado Pago account without your permission, contact Mercado Pago straight away and ask them to block the receiving account. Wallet money moves fast, so the first minutes matter most.
Do this first
- Call Mercado Pago’s official line below, or use help inside the official Mercado Pago app. Never use a number from a text, a caller or a search result.
- Give them the transaction ID, the amount, the time and the number or account you paid, and ask them to block it.
- Change your PIN and password if anyone may know them. Mercado Pago will never ask for your PIN or a one-time code.
- Report it to the police too: see who handles cybercrime in Argentina, and keep screenshots of every message and payment.
