Mercari Customer Service, Returns, Buyer and Seller Help

If you need help with a Mercari purchase, sale, return, refund, missing package, payout, account restriction, unauthorized transaction or suspected scam, start with the support route connected to the transaction. Mercari provides online support through its Help Center and app and publishes a phone number for order and payment problems.

Mercari is an online marketplace where individuals can buy and sell new and used merchandise. Buyers and sellers should keep transactions, payments and messages inside Mercari because protections may not apply to activity conducted outside the platform.

Mercari Returns and Refunds

Mercari’s return process has strict deadlines. Buyers should inspect an order as soon as it arrives and open a return through the Order Status or Rating page if the item qualifies.

Mercari currently considers return requests made within 72 hours of carrier-confirmed delivery and before transaction completion for reasons that include:

• The item is significantly different from the listing description
• The item was damaged during shipping
• The item is inauthentic or counterfeit

Reasons such as changing your mind, an item not fitting, minor cosmetic imperfections that do not affect functionality or ordinary carrier/weather delays generally do not require Mercari to approve a return.

Do not simply mail the product back to the seller on your own. Mercari says buyers should use the return process provided through the transaction. Independently returned or refused packages may not qualify for a refund.

The Mercari 72-Hour Return Deadline

Mercari automatically completes transactions after the buyer review period. Buyers normally have 72 hours after carrier-confirmed delivery to inspect the item, report a qualifying problem and request a return.

If you need a return:

1. Open the affected order in Mercari.
2. Choose the return or problem option before rating the seller.
3. Describe how the item differs from the listing.
4. Upload clear photographs when requested.
5. Keep the packaging and shipping materials.
6. Wait for Mercari’s return instructions.

Submitting the request through the Order Status or Rating page pauses transaction completion while Mercari reviews the problem. Simply emailing or messaging about the issue may not pause the transaction.

Mercari Approved Return Shipping

When Mercari approves an eligible return of an item weighing up to 50 pounds, it generally provides a prepaid return label. The buyer must drop the package with the designated carrier within 72 hours of receiving the label.

Mercari also requires tracking activity within the applicable return period. If the return is not shipped as instructed, the return can be voided and payment may be released to the seller.

Photograph the item, packaging and completed return package before shipment. Save the carrier receipt and tracking information until the refund is complete.

Mercari Refund Timing

For approved returns above Mercari’s nominal-value threshold, Mercari says the refund is processed to the original payment method within 14 calendar days after confirmation that the buyer returned the item using the provided label.

For some lower-value returns, Mercari may issue account credit instead of requiring the item to be shipped back. Current Mercari policy states that this type of account credit expires 90 days after issuance.

Refund timing after Mercari processes the refund can also depend on the bank, card issuer or payment method.

Mercari Item Marked Delivered but Not Received

If tracking says an order was delivered but you do not have it, contact Mercari quickly. Current policy requires buyers to contact Mercari within 72 hours of the carrier-confirmed delivery time for a delivered-but-not-received investigation.

Before opening the request, check:

• Front door, side door and other delivery locations
• Apartment mailroom or package locker
• Household members
• Neighbors when appropriate
• Carrier tracking details

Do not rate the seller while a delivery problem is unresolved. Opening the issue through Mercari allows the transaction to be reviewed before payment is finalized.

Mercari Buyer Protection

Mercari Buyer Protection is tied to transactions completed through Mercari. The platform holds payment while the item is shipped and the buyer has an opportunity to inspect it.

Buyers should keep all communication and payment inside Mercari. Payments or arrangements made outside Mercari may not receive marketplace protection.

Current Mercari fees include a Buyer Protection fee of 3.6% of the item price plus buyer-paid shipping for listings covered by its current fee structure. The amount is displayed during checkout.

Review the final checkout screen before buying because product price, shipping, taxes and applicable fees can all affect the total.

Mercari Seller Fees

Listing an item on Mercari is currently free. Under Mercari’s current fee structure, sellers pay a 10% selling fee when an item sells. The fee applies to the item price plus buyer-paid shipping.

Mercari’s current structure also applies the 3.6% Buyer Protection fee to buyers. Mercari does not separately charge the additional payment-processing fee that applied under some earlier fee structures.

Because Mercari has changed its fee structure more than once, sellers should check the current Mercari Fees page before pricing an item or relying on an older seller guide.

Mercari Seller Payouts

After a transaction completes, the seller’s earnings are added to the Mercari balance. Sellers can then use the balance on Mercari or withdraw funds.

Mercari currently provides two principal cash-out methods:

• Direct Deposit: Successful ACH withdrawals currently have no fee and generally arrive within several business days. A $2 fee applies to a failed deposit request.
• Instant Pay: Currently costs $3 per withdrawal and can make funds available within minutes, depending on the bank. Mercari lists a $600 monthly Instant Pay limit and requires eligible account and debit-card verification.

Government ID verification is required for Instant Pay. Direct deposits can only be made to checking accounts, and Mercari requires sellers to use their own bank information.

If a payout fails, first verify the routing number, account number and account-holder information. If the information is correct, contact the bank and Mercari before repeatedly submitting the same transfer.

Mercari Shipping Protection

Mercari prepaid shipping labels can include Shipping Protection when the seller follows the program requirements. Current Mercari protection is up to $200 for eligible standard, economy and Media Mail shipments and up to $20 for eligible First-Class Envelope shipments.

Important requirements can include:

• Using a Mercari prepaid label
• Using the correct carrier
• Shipping within the required period
• Using accurate package weight and dimensions
• Obtaining carrier acceptance and tracking scans
• Packaging the item appropriately
• Keeping the Mercari account in good standing
• Using original listing photographs

If a seller chooses to ship with an independently purchased label, the shipment does not qualify for Mercari Shipping Protection. Sellers may want to purchase appropriate carrier insurance for higher-value items.

Mercari Damaged or Lost Package Claims

If an item is damaged in transit, keep the product, box, packing material and shipping label. Mercari may request photographs of all of these as part of a return or Shipping Protection review.

Sellers should also keep the carrier acceptance receipt. Without appropriate tracking or possession scans, a Shipping Protection claim may not qualify.

For damaged returns, sellers have particularly short reporting deadlines. Review the transaction immediately when a returned package arrives and use Mercari’s order-specific support route if the item was returned damaged.

Mercari Counterfeit and Authenticity Problems

If you believe an item may be counterfeit, do not rate the transaction. Open a return request and provide Mercari with photographs and the reason you believe the item is not authentic.

Mercari specifically lists inauthentic or counterfeit merchandise as an eligible return reason when the request is made during the applicable return period.

Sellers should provide accurate descriptions and photographs and should retain receipts, serial-number documentation or other proof of authenticity for brand-name merchandise where appropriate.

Mercari Account Locked, Limited or Suspended

Mercari may limit an account while reviewing identity, payment, listing or suspicious-activity concerns. Account support is available through the Help Center rather than a separately published account-specific telephone line.

If Mercari requests identity verification, submit information only through Mercari’s secure account or Help Center process. Do not upload identification documents to a public review, send them to another marketplace user or provide them through a link sent by an unknown person.

If a listing or account was restricted for a policy reason, review the notice from Mercari and the applicable marketplace rule before contacting support. Include the relevant listing or case information in the request.

Mercari Hacked Account or Unauthorized Transaction

If you believe someone gained access to your Mercari account, change your password and secure the email account connected to Mercari. Review your saved payment methods, profile details, balance and recent transactions for changes you did not make.

Mercari advises users to use unique passwords and multi-factor authentication when available. If you cannot log in because the account was taken over, use the Help Center account-recovery process.

For suspected fraud or unauthorized payment activity, Mercari publishes 1-888-325-2168. Contact your bank or card issuer promptly as well if a financial account may be compromised.

Mercari Scam and Phishing Warnings

Marketplace users should be cautious when someone asks to move the conversation or payment outside Mercari.

Warning signs include:

• A buyer or seller asks for your email address or phone number to complete payment
• A message says you need to pay a fee outside Mercari before receiving money
• Someone asks for your bank login, card information or verification code
• A supposed Mercari representative asks for your password
• A message contains a link to an unfamiliar website
• A buyer asks you to ship to an address different from the Mercari order
• Someone asks you to rate an item before it arrives
• A transaction requires gift cards, cryptocurrency, wire transfer or another off-platform payment

Mercari says official email communications use the @mercari.com domain. It also warns that Mercari does not contact customers through ordinary buyer-seller chat messages; official in-app communications appear through Mercari notifications.

Report suspicious listings and messages through the platform. Do not continue an off-platform conversation simply because another user claims Mercari requires it.

Mercari Prohibited Items and Removed Listings

Mercari maintains a detailed prohibited-items policy. Listings can be removed and accounts can be limited or suspended when prohibited merchandise or prohibited conduct is detected.

Examples of restricted categories include illegal drugs, prescription medicines, counterfeit goods, firearms and certain weapons, alcohol, tobacco and nicotine products, certain financial products, digital goods and other items that violate Mercari policy or applicable law.

The list can change. Sellers should check the current Mercari Prohibited Items policy before listing a product in a regulated or unusual category.

How to Escalate a Mercari Complaint

1. Open the affected purchase, sale, payment or payout inside your Mercari account.
2. Use the transaction-specific support option whenever possible.
3. For orders or payments, call 1-888-325-2168 during published phone hours when needed.
4. Save screenshots, tracking information, photographs and receipts relevant to the case.
5. Keep the Mercari inquiry or case number.
6. Respond promptly when Mercari requests additional photographs or verification.
7. If the first response does not address the issue, follow up through the existing inquiry and clearly state what remains unresolved.
8. For an unauthorized bank or card transaction, contact the financial institution in addition to Mercari.

Do not send repeated payments, return an item outside Mercari’s authorized return process or move a disputed transaction off the platform simply because another user requests it.
