Mercado Libre: How to Report a Scam or Fraud

Scammed by a seller, charged for an order you didn’t place, or contacted by someone claiming to be Mercado Libre? Here are the official ways to report it in 3 countries, read on Mercado Libre’s own help pages, plus the buyer-protection deadline and where to escalate.

Do this first

  1. Stop all contact and payments. Mercado Libre will never ask you to pay outside its own checkout, share a one-time code or install a remote-access app.
  2. Report it inside the official Mercado Libre app or website (steps below), not through a link or number you were sent.
  3. Mercado Libre has no public customer-care phone number. Any number claiming to be Mercado Libre support is a scam.
  4. If you paid by card, bank transfer or a payment app, call your bank’s fraud line now: see Bank Fraud Help.
  5. Watch the buyer-protection deadline below: claims made late are usually refused.
