  1. All verified Mercari users have a badge of a shield with a checkmark in the center. This proves that they’ve taken steps to confirm their email and phone number and that they’ve uploaded a valid copy of their government ID. [4]
  2. Any legitimate seller will expect payment through the Mercari platform, and won’t ask you to send money through a different channel. [5]
    • If you receive a suspicious DM from a seller on Mercari, hit the flag icon next to the message to report it.
  3. Mercari has a 3-day return policy for buyers in case your purchase doesn’t meet your expectations. Before giving the seller a rating, initiate a return within Mercari. [6]
    • To request a return, go to the “Order Status” page and select “Get help,” followed by “This is about returning my purchase” and “I want to return my purchase.” Explain why you’re requesting a return, and wait 24 hours to see if the seller gets in touch. After that point, Mercari will review the request.
  4. If an item seems to violate Mercari’s prohibited items policy , pull open the listing and hit the flag icon in the top right corner. Detail why you’re reporting the listing, and then hit “Submit” and “Yes” to confirm. [7]
    • Coupons, counterfeit items, digital items, and inappropriate items are all banned from the Mercari platform.
  5. Whenever possible, look for sellers with good ratings and reviews—that way, you can be confident that you won’t be scammed. Sellers with zero reviews are more likely to be scam accounts.
    • It’s also important to keep the price point for items in mind. If a deal seems too good to be true, it probably is.
    • Mercari has an established refund policy in place, so it’s not hard to get your money back. Still, it’s best to avoid scams in the first place so you don’t have to deal with that hassle in the first place.

  1. Look for a shield-like icon with a white checkmark in the center—this proves that the buyer took the time to provide a legitimate government ID and confirm their phone number and email. [8]
    • On their website, Mercari reminds sellers that profile verification doesn’t 100% vet a buyer. It’s always best to follow your gut before doing business with any buyer—if you’re getting bad vibes, feel free to call the order off.
  2. Ignore any buyer requests to accept payment later (like upon delivery), as this makes it easier for a scam to occur. Instead, require all buyers to use any of the payment methods offered by Mercari, including: [9]
    • Visa, Mastercard, Discover, and American Express
    • PayPal
    • Venmo
    • Zip
    • Apple Pay
  3. Services like PayPal make it easy to check if the money sent over by the buyer cleared properly. [10] Double-check that the payment is good to go before you ship anything out.
  4. Use Mercari’s built-in messaging system by hitting the “Message” button on the buyer’s profile. [11] That way, if anything goes wrong with the transaction, Mercari can easily reference your in-app communications.
  5. Mail and shipping services like USPS allow you to request a signature confirmation for a package before you send it out. [12] Taking this extra step prevents scammers from pretending that they never received a package.
  6. Take plenty of photos of the item and provide a detailed description of what it is (including its condition). Provide the brand of the item (if applicable), so potential buyers can get the full picture. [13]
    • Include pictures that highlight any of the product’s issues or cosmetic defects, so the reader knows exactly what they’re buying.
    • For designer items, include pictures of details that prove the item’s authenticity, like a serial number.
    • Mention any accessories that come with the item, so the buyer can’t pretend something was missing from their package.
    • Take a video of you packaging the item to help prove your legitimacy as a seller.

Common Mercari Scams

  1. Some buyers may try to waste a seller’s time or steal their money with tricks like:
    • Low price offers: Some buyers may attempt to haggle for a price that’s much lower than the established listing. Then, they’ll back out of the offer later.
    • No payment: Certain buyers may request a delayed payment method (like paying after the item is delivered). Later, they’ll receive the item but never pay for it.
    • Bogus returns: Some crafty buyers will purchase an item that they already own a damaged version of, so they can take a picture of their damaged item and use it to get a refund. Then, they’ll return the busted item to you and sell the high-quality item they scammed from you.
    • Sketchy emails: Some buyers use email phishing tactics to get a seller’s personal payment information (like a bank account number).
  2. Sellers using online platforms like eBay, Facebook Marketplace, and Mercari often use cheap schemes to scam buyers, like:
    • Dropshipping scam: The seller lists Amazon items on their shop at a higher price, forcing buyers to pay extra shipping fees. In actuality, the seller is buying the item on Amazon and having it shipped directly to the buyer.
    • Fake items: Sellers try to pass off counterfeits as the real deal, especially when it comes to designer goods. Thankfully, the Mercari Authenticate feature makes this scam easier to avoid.
    • Address switching: Sellers send a bogus package in the mail to your address, only to contact the shipment company and change the address before it gets to you.
