Part of: Marketplace Seller Scams
Last reviewed: 1 June 2026
Online marketplace fraud in Brazil mirrors the pattern seen globally, but Pix has displaced bank TED/DOC transfers as the payment method of choice because of its speed and zero cost. Fraudulent sellers on OLX, Facebook Marketplace, and similar platforms list desirable goods — electronics, vehicles, appliances — at attractive prices and insist on Pix payment before any in-person meeting or delivery.
Because Pix settles instantly and permanently, the scammer can receive and withdraw funds in the time it takes the buyer to travel to the agreed meeting point. The seller's Pix key (usually a phone number or CPF) is typically linked to an account opened with a fintech under a third-party identity, reducing traceability.
How this scam works on Pix
A listing appears on a marketplace with below-market pricing and photos that may be stolen from a legitimate seller. The fraudulent seller insists on Pix before arranging the transfer or meeting, citing security or logistics. In vehicle scams, a 'reservation deposit' of [amount] reais is requested via Pix, after which the seller becomes unreachable or raises the price further.
Some scammers conduct a fake Pix confirmation: they send a fabricated 'comprovante' (payment receipt) to the buyer claiming they have already paid and must now hand over the item, attempting to reverse-fraud a legitimate seller. Always verify that funds actually appear in your account — not just a screenshot — before releasing any goods.
Common red flags
- Seller insists on full or partial Pix payment before meeting or before delivery
- Price is significantly below market with no clear explanation
- Seller's profile was created recently or has no review history
- Seller communicates only through WhatsApp with a new, unverified number
- A 'comprovante' screenshot is sent as payment proof — always confirm the credit in your app
- In vehicle listings, seller claims to be in another state and proposes delivery after Pix transfer
How to protect yourself
- Always inspect goods in person before any Pix transfer — meet in a public place with security cameras
- Verify a vehicle's ownership documents against Detran records before paying any deposit
- Never accept a comprovante screenshot as proof — log in to your bank app and confirm the credit independently
- For high-value purchases, use a notarised escrow arrangement rather than direct Pix
- Reverse-image-search product photos to confirm they have not been copied from another listing
How to report it
- Report the fraudulent Pix key via the MED mechanism through your bank app within 80 days
- File a police report (Boletim de Ocorrência) online via the relevant state Delegacia Virtual
- Report the listing to OLX or Facebook Marketplace using the platform's fraud report tool
Frequently asked questions
Is it ever safe to pay Pix before receiving a product?
For unknown sellers, paying before inspection carries material risk. If advance payment is unavoidable, limit the exposure, use a Pix key linked to a verified legal entity (CNPJ), and confirm the comprovante directly in your bank app rather than from a screenshot. For large-value transactions, a notarised escrow or a registered marketplace with buyer protection is strongly preferable.
