In this guide
Mercari is not a store: it’s a marketplace where individuals sell to each other, and Mercari sits in the middle holding the money. The company is real and the payment system works; whether a specific purchase goes well depends on the seller and on how fast you act when the box arrives.

Who runs Mercari?
Mercari, Inc. was founded in Tokyo on February 1, 2013 and is listed on the Tokyo Stock Exchange (ticker 4385). The US marketplace at mercari.com is operated by its US subsidiary, based in Palo Alto, California. The Better Business Bureau lists the US business as started in 2014.
Mercari doesn’t own or inspect the items. Sellers write the listings, take the photos and ship the package. Mercari processes the payment, provides shipping labels and decides claims.
What protection you actually get
| Protection | What Mercari says |
|---|---|
| Payment hold | Your payment is held until the item is delivered and you rate the order. The seller is paid only after that. |
| Problem window | 72 hours after carrier-confirmed delivery to report an item that isn’t as described, through the Help Center. |
| Auto-complete | If you don’t rate within 72 hours, the order completes automatically and the money goes to the seller. After that, “all sales are final.” |
| What’s covered | Item damaged in shipping, wrong item, or an item that significantly doesn’t match the photos, description or condition. |
| Returns on approved claims | Mercari sends a free return label; you must ship the item back within 3 days of claim approval to get the refund. |
| Not covered | Items that don’t fit or aren’t your style, odor or cleanliness complaints, change of mind, or having bought a similar item on another platform. |
Mercari fees for buyers and sellers
Since January 6, 2025, Mercari’s US fee structure is:
| Fee | Who pays | Amount |
|---|---|---|
| Buyer Protection fee | Buyer | 3.6% of the item price plus buyer-paid shipping |
| Selling fee | Seller | 10% of the item price plus buyer-paid shipping |
| Payment processing | Nobody | No separate fee under the new structure |
| Instant Pay cash-out | Seller | $3 per cash-out |
| Failed direct deposit | Seller | $2 per failed request |
One exception: on older listings that the seller hasn’t updated since the change, Mercari says a 10% buyer fee applies instead of 3.6%. Check the fee line at checkout before you pay.
How to buy on Mercari safely
- Read the whole listing. Condition, measurements, flaws and brand claims in the description are what a “not as described” claim is judged against. If something important is missing, ask the seller in Mercari’s messages before buying.
- Check the seller’s profile. Look at their ratings and past reviews. A new account selling expensive branded items at a deep discount deserves extra questions.
- Pay only inside the app or website. Mercari accepts major credit cards, PayPal, Apple Pay, Mercari credit and your Mercari balance. It states plainly that it does not protect payments sent outside the app or site.
- Make an offer if you like, but keep all negotiation in Mercari’s messaging so there’s a record.
- Track the package. Sellers are asked to ship within 3 business days. Know the delivery day so you can open the box right away.
- Inspect within hours, not days. Photograph the item and packaging. If there’s a problem, open a report in the Help Center before 72 hours pass and before you rate.
- Rate only when you’re satisfied. Rating releases the money to the seller.
Common Mercari scams and problems
- Moving you off the platform. A seller asking you to pay through another payment app, or to text or email them directly, removes your protection. Mercari says it can’t help with interactions outside the app or site.
- Counterfeits and misdescribed items. Trustpilot reviewers frequently report fake or damaged goods. Your remedy is the 72-hour claim, so inspect branded items carefully.
- “Too good to be true” and urgent requests. Mercari’s safety guidelines warn against sending money to strangers for deals that seem too good to be true or to fix an “urgent” situation.
- Missing the window. The most common way buyers lose protection is simply waiting too long; after auto-complete, refunds aren’t provided.
What independent ratings say
When we checked (September 29, 2026), Mercari’s US profile had an A rating from the Better Business Bureau and was listed as accredited since July 8, 2026, with 5,693 complaints filed against the business. On Trustpilot, the mercari.com profile had a TrustScore of 1.2 (“Bad”) from about 20,500 reviews. Recurring complaints there include customer service, denied refund claims, the tight 72-hour window, counterfeit or damaged items and lost packages.
These numbers don’t mean Mercari is a scam: any large peer-to-peer marketplace generates disputes, and unhappy users are more likely to post reviews. They do mean you shouldn’t count on customer service to rescue a late or weak claim.
Verdict: is Mercari safe to buy from?
Mercari is a legitimate, publicly listed company and its payment hold does protect you, as long as you stay inside the app and act within 72 hours of delivery. It works best for items you can verify quickly: clothes with clear photos, books, games, household goods. For expensive branded items, ask for extra photos first, and remember that fit and change-of-mind aren’t covered. If you want guaranteed returns, a retailer such as Amazon or Walmart gives you far more time; for refurbished tech, see whether Back Market is legit.
