Quick answer

If you bought an item as genuine and received a counterfeit, treat it as an authenticity or "not as described" dispute. Don't call the transaction unauthorized when you approved the payment. Preserve the item and its packaging, save the original listing, ask the seller for a refund in writing, and open the appropriate payment or marketplace case before its deadline.

For a U.S. credit card, contact the issuer promptly and send written notice within 60 days after the first statement containing the billing error was sent if you want the federal Fair Credit Billing Act protections. A phone call alone may not be enough. PayPal, Amazon, and eBay have separate deadlines, and a marketplace deadline doesn't extend a card-dispute deadline.

Important: A counterfeit claim is usually about what the seller delivered, not whether you authorized the payment. Describe the problem accurately.

Which remedy fits the purchase?

These routes are related, but they aren't the same:

• Merchant refund: The seller voluntarily returns your money.
• Marketplace claim: Amazon, eBay, or another platform reviews the order under its buyer-protection rules.
• PayPal claim: PayPal reviews an eligible payment under its purchase-protection terms.
• Chargeback: The card issuer uses the card-network dispute process to seek a reversal or recovery from the merchant's bank.

You can contact the seller while deciding which formal route to use. Tell each provider about any other case, refund, or temporary credit, and don't seek or keep duplicate refunds. PayPal's terms also require buyers to choose between pursuing PayPal protection and pursuing the card issuer for the same transaction.

There isn't a reliable universal success rate for counterfeit disputes. The result depends on the payment method, the seller's promise, the evidence, the seller's response, and the rules that apply to that particular order.

Preserve the evidence before filing

Keep the item as received

Set aside the product, box, tags, labels, inserts, and shipping materials. Don't clean, repair, alter, discard, or resell the item before documenting it. If the product is a cosmetic, charger, toy, electronic, safety product, or anything else that may be hazardous, stop using it.

Don't mail it to an unverified address. If the seller, marketplace, brand, or payment provider requires a return, use the instructions it gives you.

Save the listing and order record

Listings can change or disappear once a dispute starts. Save screenshots or a copy of:

• Any statement that the product was authentic, genuine, new, or authorized
• The description, photographs, model number, and stated condition
• The seller's name, storefront, and order number
• The price, shipping terms, and return policy
• The purchase date and promised delivery date
• The receipt, order confirmation, and payment record

Photograph the specific problem

Take both full-item photographs and close-ups. Capture logos, fonts, stitching, materials, hardware, labels, serial numbers, barcodes, holograms, software licenses, packaging, and the features that make you question authenticity.

A serial-number lookup isn't enough on its own. Counterfeiters can copy valid numbers, and some brands don't offer public verification tools.

For an expensive watch, luxury item, jewelry, or sneaker, a written opinion from the brand, an authorized service center, or a reputable authentication professional may help. For electronics, preserve the model information, certification markings, serial details, software behavior, and external components. Only inspect internal components if doing so won't damage the item. For digital goods, save the advertised license, download information, activation messages, and relevant account or file details without running suspicious software.

Contact the seller in writing

Keep the message short and factual. Identify what the listing promised, describe what arrived, explain the specific authenticity concern, and request the refund you want. Ask for a response by a reasonable date.

Save the reply and any return instructions. If the seller doesn't answer or refuses to help, preserve that fact as part of the timeline. It supports your account of what happened, although it doesn't by itself prove that the product is counterfeit.

Choose the route for your payment method

If PayPal was funded by a credit card, don't file a PayPal claim and a card chargeback at the same time without asking how the providers want you to proceed. Disclose any case or refund already received.

How to dispute the purchase on a U.S. credit card

The FTC's guidance on credit-card billing errors explains the federal notice and investigation rules.

1. Call the issuer now. Say that you authorized the purchase, the seller advertised the goods as authentic, and the goods you received appear not to be authentic. Ask which dispute category, submission method, and address apply.
2. Send written notice. To preserve FCBA protections, dispute the charge in writing within 60 days after the first statement containing the error was sent to you. Use the billing-dispute address or method identified by the issuer. Don't assume that a general customer-service chat or phone call satisfies the written-notice requirement.
3. Identify the transaction. Include the merchant name as it appears on the statement, transaction date, amount, order number, and the account information the issuer requests. Explain the problem in concrete terms rather than simply writing "fraud."
4. Attach a focused evidence file. Include the listing, receipt, payment record, photographs, authentication report if available, seller messages, and return or tracking records. Keep the originals.
5. Wait for return instructions. Don't send the item back until the seller, marketplace, PayPal, or issuer tells you where and how to return it. If a return is required, use tracking and keep the shipping receipt.
6. Watch for follow-up requests. Respond by the date given. Tell the issuer if another provider refunds you or issues a credit.
7. Pay the undisputed balance. If the dispute is handled under FCBA procedures, the FTC says you don't have to pay the disputed amount or related finance and other charges while the issuer investigates. Continue paying charges that aren't part of the dispute.

The issuer generally must acknowledge a written dispute within 30 days unless it has already resolved the problem. Under the FTC guidance, it must resolve the dispute within two complete billing cycles and no later than 90 days after receiving the letter.

The FTC also notes that some issuers may extend the 60-day period when a shipment is delayed. Ask the issuer about that possibility; don't rely on an extension that hasn't been confirmed.

Evidence that makes a counterfeit claim clearer

A reviewer should be able to follow a simple chain: what the seller promised, what arrived, what feature shows the mismatch, and what you asked the seller to do.

More useful evidence

• A listing or message that expressly promises an authentic or genuine product
• Clear photographs of inconsistent logos, fonts, materials, stitching, hardware, packaging, or labels
• A written opinion identifying the specific item from the brand, an authorized service center, or a reputable authentication professional
• A serial-number or product-record result, together with an explanation of what it proves
• The receipt, order confirmation, and payment record
• Seller messages showing uncertainty, a changed description, or refusal to provide a reasonable refund
• Return tracking, delivery confirmation, or proof that the seller refused the return

Evidence that is weak by itself

• A price that seems unusually low
• Poor seller reviews
• Packaging that differs from a newer version
• A generic authentication-app result with no explanation
• A valid serial number without other supporting evidence
• Proof that a package was delivered

Delivery confirmation shows that something arrived. It doesn't show that the contents were genuine. An expert report can strengthen a claim, particularly for a high-value item, but no single report is a universal requirement for every issuer or platform.

PayPal, Amazon, eBay, Visa, and Mastercard

PayPal

Under PayPal's U.S. Purchase Protection terms, a dispute must be opened within 30 days of delivery or fulfillment, or within 180 days after the payment date, whichever comes first.

Open the dispute through PayPal's Resolution Center, describe the item as not authentic or not as described, and provide the listing and authenticity evidence. If the seller doesn't resolve it, follow PayPal's escalation instructions. Don't close the case merely because the seller promises a refund; wait until the money is actually returned and the case instructions allow closure.

PayPal's terms also address a buyer's choice between PayPal protection and a card-issuer claim for the same transaction. A buyer can't pursue both routes at once or obtain a double recovery.

Amazon

An Amazon A-to-z claim is a marketplace remedy, not a card chargeback. Amazon's rules vary by country and order type.

For example, the Amazon A-to-z Guarantee page for the EU marketplace includes conditions involving contact with the seller for more than 48 hours and a last possible delivery date within 90 days. Those are EU-marketplace conditions, not a deadline to copy onto a U.S. order.

For a U.S. purchase, open the order in your Amazon account, contact the seller through Amazon, and follow the deadline and evidence instructions shown for that transaction. If you later contact your card issuer, disclose the Amazon case and any refund.

eBay

Use the order-history page to open the current Money Back Guarantee request for the purchase. Describe the problem as an authenticity issue or an item not as described, upload the listing and photographs, and keep communications on eBay.

An eBay decision doesn't replace the card issuer's process. If you contact your bank as well, tell it that an eBay case is open or has already been decided.

Visa and Mastercard

Visa and Mastercard set network rules used by issuers and merchants. They aren't a single consumer complaint office that decides every counterfeit claim. Start with the bank that issued your card and ask which dispute category and deadline apply.

Don't assume that a 120-day deadline found online applies to every U.S. purchase. For example, Visa's consumer chargeback guidance for the UK refers to 120 days in that market. It doesn't replace the U.S. credit-card written-notice rule or your issuer's instructions.

If the seller or issuer denies the claim

Read the reason for the denial before sending more material. Ask:

• What rule or requirement led to the denial?
• Which evidence did the reviewer consider?
• What document or explanation was missing?
• Is there a reconsideration, appeal, or second-review deadline?
• Is another dispute stage available?

A denial may reflect a missed procedure, weak documentation, a return problem, or the seller's response. It isn't necessarily a finding that the product is genuine.

A useful rebuttal is short. Quote or identify the seller's promise, connect it to the specific defect in your photographs, and attach the authentication evidence that addresses the reason for denial. Avoid sending a long narrative filled with unrelated screenshots.

If the seller appears to be part of a wider scam, report the account to the marketplace and the brand. The FTC's advice for people who were scammed recommends contacting the company that handled the payment and asking it to reverse the transaction. For a high-value loss, a qualified consumer lawyer or local consumer-protection office may be another escalation option, but don't let that delay a payment-provider deadline.

If you're a seller defending a counterfeit allegation

Respond through the official marketplace or payment-processor channel by the deadline shown there. Delivery confirmation, a signature, and tracking can show that a package arrived; none of them proves authenticity.

Useful records may include:

• The exact listing and product photographs
• Invoices from an authorized distributor
• Chain-of-custody, serial-number, lot, or warehouse records
• Authentication documents identifying the specific item
• Pre-shipment photographs that match the returned or disputed product
• Messages showing what condition and authenticity were promised
• Tracking and delivery records

Submit honest, contemporaneous records. Don't edit documents, create a certificate after the fact, move the dispute off-platform, or pressure a buyer to withdraw a truthful claim.

If the evidence suggests the product may be counterfeit, stop selling it and cooperate with the platform, payment provider, brand, or other authorized process. A no-refund policy and proof of delivery don't override a credible authenticity problem.

Mistakes that can weaken the dispute

• Calling an authorized purchase an unauthorized transaction
• Waiting for the seller while a card or marketplace deadline approaches
• Returning the item without written instructions or traceable shipping
• Altering, repairing, cleaning, or discarding the item before documenting it
• Filing overlapping PayPal, marketplace, and card claims without disclosing them
• Accepting a partial refund without checking whether it settles or closes the dispute
• Submitting edited screenshots or exaggerating the defect
• Treating a serial-number lookup as conclusive proof of authenticity

Frequently asked questions

Can I file a dispute without an expert authentication report?

Yes. Submit the evidence you have, such as the listing, photographs, messages, order record, and product identifiers. An expert or brand report may strengthen a high-value claim, but there isn't one universal report requirement for every issuer or platform.

Does a seller's no-refund policy prevent a chargeback?

Not automatically. The seller's policy is part of the transaction record, but the card issuer or marketplace applies its own rules. Ask the seller for a refund anyway and preserve the response.

Should I return a counterfeit item?

Only after the seller, marketplace, PayPal, or card issuer gives you return instructions. Photograph the item first, use tracked shipping if a return is required, and keep proof of delivery. Don't close a dispute until you understand how the return affects it.

What if I paid with a debit card?

Contact the bank immediately and ask about its counterfeit or merchandise-not-as-described process. The federal 60-day written-notice rule described by the FTC is a credit-card rule; it doesn't automatically provide the same protection for debit or prepaid cards.

Is the 120-day Visa deadline always available?

No. Deadlines depend on the payment route, jurisdiction, transaction facts, and issuer process. A general Visa page from another country isn't a substitute for the instructions from your U.S. card issuer.

If a deadline is close, open the appropriate issuer, PayPal, Amazon, or eBay case now, keep the confirmation, and provide additional evidence through that case if the provider allows it.
