How to verify a seller online (without getting scammed)

Most online scams happen because the buyer can't actually verify who the seller is. Here is a clear, no-nonsense checklist you can use on Facebook Marketplace, Gumtree, OLX, DoneDeal, Mercado Libre, Carousell — anywhere with anonymous listings. Or skip the work and use a marketplace where every seller is already verified.

1. Check the profile, not the listing

A polished listing means nothing. A real profile has photos that don't reverse-image-search to a stock site, a long enough account history to predate the listing, reviews from real conversations, and a consistent name. New accounts with one listing and no history are the single biggest red flag.

  • Account age and listing history
  • Reverse image search the profile photo
  • Consistent name across profile, payment, and ID
  • Reviews that look like real conversations

2. Verify identity, not just the chat

Ask for a video call before you pay anything substantial. A scammer will refuse, claim a broken camera, or vanish. If the marketplace offers ID-verified sellers (Safegram Exchange does, Facebook Marketplace doesn't), filter to verified only — it cuts scam attempts by an order of magnitude.

3. Keep payment outside the chat

Never pay through links sent in chat. Use the marketplace's built-in payment if it exists, or meet in person and pay on the spot. Bank transfers, gift cards, crypto and Pix to a phone number are the four payment methods scammers prefer because they're irreversible.

  • Avoid bank transfers to a name you can't verify
  • Never use gift cards as payment
  • Avoid Pix or instant transfer to a phone number you don't know
  • Prefer in-person cash, escrow, or platform-native payment

4. Watch the red flags

Price way below market, urgency ('I have another buyer waiting'), refusal to do a video call, off-platform payment, shipping requests for a local item, sob stories about why they can't meet — any one of these is a hard stop.

5. Or use a marketplace where verification is the default

On Safegram Exchange, every seller is identity-verified before they can list. You can see a verified Trust Ring on every profile, chat in end-to-end encrypted DMs, and avoid almost all of the verification work above. It's the same idea as eBay or Vinted's verified-seller programmes, but applied to every listing by default — not just the premium ones.

Frequently asked questions

How do I verify a Facebook Marketplace seller?

Facebook Marketplace doesn't verify seller identity. The best you can do is check account age, ask for a video call, reverse-image-search the profile photo, and refuse off-platform payment. Even then, the scam rate is high — which is why verified marketplaces like Safegram Exchange exist.

What is the safest way to pay an online seller?

In-person cash, an escrow service, or the marketplace's built-in payment. Avoid bank transfer, gift cards, crypto, and instant payment to a phone number — those are irreversible and preferred by scammers.

What is a verified seller?

A verified seller is someone who has passed a government-ID check (and sometimes a selfie liveness check) with the marketplace. On Safegram, every seller on Safegram Exchange is verified before they can list. This makes impersonation and throwaway-account scams effectively impossible.

Is it safe to meet a marketplace seller in person?

Yes, with basic precautions: meet during the day in a public place (a police station car park or a busy shopping centre), bring a friend, pay in cash, and inspect the item fully before handing over money.
