How to Tell If Something Is Counterfeit: Signs and the Law

You can usually tell if something is counterfeit from several signs at once rather than one. Watch for a price far below what the brand charges, a seller you can't verify, sloppy packaging, labels or stitching, and a serial number that doesn't check out with the manufacturer. When authenticity matters, buy from the brand or an authorized retailer and pay with a method that lets you dispute the charge. U.S. Customs and Border Protection also treats counterfeits as illegal imports, so a fake you order from abroad can be seized.

Counterfeits aren't limited to street stalls and vacation markets. Plenty are sold online, in stores and listings that look legitimate at first glance. At TrustCamera we build a camera app that gives photos a check code at the moment they're taken, so we spend a lot of time on listing photos that don't show what's really for sale. Below you'll find the red flags before and after you buy, what federal rules say about buying fakes, and what to do if you end up with one.

How to tell if something is counterfeit: the warning signs at a glance

A genuine branded product comes with a believable price, a seller you can check and consistent quality down to the smallest detail. A fake usually gives itself away in several places at once: in the listing, on the packaging, in the labels and seams, and for electronics in the serial number and markings. The more of these signs you find together, the more likely the item isn't real.

Use this checklist before and after you buy. The right-hand column is our own assessment, and it depends a lot on the brand and the product.

One sign alone proves little. Genuine items go on sale, and some legitimate sellers use the brand's product photos. When a bargain price, an unclear seller and a flaw in the details show up together, though, walk away. Many fakes are sold through online stores that are fakes themselves. Our guide on how to tell if a website is legit shows how to vet a store before you pay.

Price and seller: how to tell if a product is counterfeit before you pay

Price is often the first and clearest clue. Compare the listing with the brand's own store and with major retailers. A solid discount during a sale is normal. A nearly new designer bag at a quarter of its usual price is not. For new items, in our view it's worth checking the brand's website, since some brands list their authorized retailers there.

Next, look at who is actually selling. On Amazon, Walmart and other large marketplaces, many third-party sellers list products next to the brands themselves. Check the seller's name, location and history rather than the brand name at the top of the listing. If a seller has the same luxury bag in every color and size at a discount, or dodges questions about where the stock comes from, treat that as a warning.

Glowing reviews only help up to a point, because they can be bought or copied from other listings. Our guide on how to spot fake reviews explains what paid ratings look like. If the seller ships from overseas, keep the customs rules further down in mind as well.

Packaging, labels and stitching: what to check when it arrives

Sometimes you can only tell if something is counterfeit once the box is open. Compare the item with the official product photos on the brand's website, and look closely at fonts, logo placement and colors on the box and labels. Blurry printing, spelling mistakes in the inserts or a missing care label are typical warning signs. Packaging is easy to copy, though, so a nice box on its own proves little.

Then check the workmanship. For bags, shoes and clothing, that means even stitching, clean edges, solid zippers and metal hardware without rough spots. A strong chemical smell or materials that feel cheaper than expected are further clues. With perfume and cosmetics, fakes sometimes stand out through a different scent, texture or a cap that doesn't fit well.

These details vary a lot between brands, and good fakes come very close to the original. If you're unsure about an expensive item, ask the brand or one of its stores whether they can take a look. Be skeptical of certificates, holograms and seals as well: they get faked too, so a certificate from the seller is no substitute for a real check.

Serial numbers and accessories: how to check electronics

Electronics make it easier to tell if something is counterfeit than clothing does, because many devices have a serial number you can look up with the manufacturer. For an Apple device, Apple Support says you can open Settings, select General and then AppleCare & Warranty. The same page points to Apple's online coverage check (checkcoverage.apple.com), where you can enter a serial number. Compare the number in the device with the one on the box and the receipt.

In our view, the check on Apple's website tells you more than the screen on the device, because a fake device can imitate its settings too. A match still doesn't prove everything, since a serial number can be copied from a genuine device. Numbers that differ between device and box, on the other hand, are a clear warning sign. Only enter serial numbers on the manufacturer's official website, never on a "verification" page a seller sends you.

For cables and adapters, Apple has its own guide to identify counterfeit or uncertified Lightning accessories. Certified third-party accessories carry the MFi badge on their packaging. A genuine Apple Lightning to USB cable is printed with "Designed by Apple in California" and the place of assembly about seven inches from the USB connector, followed by a 12-digit serial number. A fake cable isn't just annoying: Apple warns it can damage your device, and the connector end can get very hot.

Buying secondhand on eBay, Vinted or Marketplace: check before you pay

It's harder to tell if something is counterfeit when you buy secondhand, because the original box is often missing. On the plus side, you can ask questions first. Request extra photos of details such as the label, the inside, the serial number or the receipt. Someone who really owns the item can usually send those quickly. A reverse image search often shows whether the listing photos come from an online store or someone else's profile.

For high-value items, a platform check helps. On eligible items in categories like sneakers, handbags, watches, jewelry, streetwear, trading cards and coins, eBay's Authenticity Guarantee has experienced authenticators examine the item before you receive it. Look for the Authenticity Guarantee checkmark on the listing. Vinted has its own rules for counterfeit items, which our guide to Vinted scams explains.

If you meet a local seller, inspect the item before you pay. If it has to be shipped, use a payment method with purchase protection so you aren't on your own if it turns out to be fake. Our guide to the safest way to pay on Facebook Marketplace compares the options, and our overview of Facebook Marketplace scams covers the tricks around payment and shipping.

Sellers can use photos to their advantage, too. With TrustCamera, you take photos directly in the app, with no uploads from your gallery, and each capture gets a check code. Share the code right away so the buyer can check it immediately for free in the browser, no account needed. They'll see that the photo hasn't changed since capture, when it was taken and roughly where (within about 10 km, or 6 miles, never the exact position). It doesn't prove the item is genuine. The app is coming soon.

Is it illegal to buy fake brands in the US?

CBP's position is blunt. On its counterfeit information page, the agency writes that purchasing counterfeit goods is illegal, and that transporting them into and throughout the U.S. may result in civil or criminal penalties. Importing counterfeits is against the law too, and individual consumers may be liable for a fine even if they didn't intend to import fakes. For trafficking counterfeit goods, CBP lists fines of up to $2 million, 10 years in prison, or both.

In our view, the more realistic risks for someone who buys a single fake for personal use are losing the item to a seizure, a possible fine and money they won't see again. Reselling is a different matter. Selling counterfeits is where, in our reading, the trafficking penalties CBP lists come into play, and passing off a fake as genuine also deceives your buyer.

State laws can add their own rules, so the answer for a specific situation can differ. This overview isn't legal advice. If you're facing a fine or a seizure notice, talk to a lawyer or a legal aid organization.

Counterfeit goods and customs: packages and souvenirs

If you order from a seller overseas, your package passes through customs. According to CBP, many online retailers ship small packages by express and international mail, and these often contain counterfeit goods. CBP says it seizes imported goods that violate U.S. laws. In our reading, a fake you order can be stopped at the border even if you only bought one, because the personal-use exception below is written for travelers.

Travelers have a narrow exception. According to CBP's guidance for travelers, people arriving in the U.S. "may be permitted" to bring in one article of each type bearing a counterfeit mark, as long as it accompanies them, is for personal use and isn't for sale. The exemption can be used once every 30 days for the same type of item. If you sell such an item within a year of bringing it in, the item or its value can be forfeited.

CBP gives an example: someone arriving with three purses may keep only one, whether they carry the same or different fake logos. The underlying regulation, 19 CFR 148.55, covers items "accompanying any person arriving," so in our reading it doesn't extend to packages shipped to you. It isn't a guaranteed right either, since CBP only says travelers may be permitted.

One more warning about packages: not every message about a delayed or held delivery is real. Our guide to the USPS text scam shows how fake delivery notices work.

Health and safety risks of counterfeit products

Fakes aren't only a problem for brands. CBP warns that many counterfeit products are made with substandard materials or components and can be hazardous to your health. Its examples include everyday products like toothpaste, shampoo, makeup and perfume, counterfeit pharmaceuticals that are missing active ingredients or contain fentanyl or other opioids, and counterfeit auto parts like airbags and brake pads.

For electronics, safety is the main concern. As mentioned above, Apple warns that counterfeit or uncertified Lightning accessories can damage your device and that the connector end can fall off or get very hot. In our view, chargers, power adapters and batteries are among the items worth buying only from retailers you know.

With cosmetics, fragrances and anything you put on your skin, the risk is harder to judge. If it's fake, you simply don't know what's inside or whether anyone tested it. Our advice: for these products, for medicine and for children's toys, skip the bargain.

Bought a fake? Get your money back and report counterfeit products

If you received a fake even though it was sold as genuine, you have options. Which ones apply depends on where you bought it and how you paid. Here's the order we'd follow:

1. Save the evidence: Photograph the item, labels and packaging, screenshot the listing, messages and payment record, and keep the item until the case is settled.
2. Contact the seller: Explain the problem in writing and ask for a refund.
3. Use purchase protection: If you paid through a platform or payment service with buyer protection, open a claim in time.
4. Report the listing: Flag it on the platform, and let the brand know if it offers a way to report fakes.
5. Report to CBP: For counterfeits coming into the country, CBP's e-Allegations portal accepts reports of suspected trade violations from the general public. It won't get your money back, and CBP only tells you whether a case is open or closed.

PayPal covers this case explicitly. Under its Purchase Protection program, an item advertised as authentic that turns out to be counterfeit counts as Significantly Not as Described. Open the dispute within 30 days of delivery or 180 days of paying, whichever comes first. If you and the seller can't agree, escalate it to a claim within 20 days, or PayPal closes it automatically. PayPal may ask you to ship the item back at your expense. Personal payments, including Friends and Family, and items bought for resale aren't covered.

If you paid by credit card, the FTC explains that you can dispute charges for things you didn't accept or that weren't delivered as agreed. Send your letter so it reaches the card issuer within 60 days after the first bill with the charge was sent to you. If the store itself was a scam, or nothing arrived at all, our guide on how to report a fake website walks you through the next steps. Whatever you do, don't resell the fake to recover your loss.

Frequently asked questions about counterfeit products

Is it illegal to buy fake designer items for personal use?

CBP says purchasing counterfeit goods is illegal and that importing them can lead to a fine, even if you didn't mean to import a fake. The heaviest criminal penalties it lists are for trafficking. In our assessment, the more likely consequences for a single item for personal use are a seizure at the border and a possible fine. State laws can add their own rules, and this isn't legal advice.

Can you get in trouble for ordering counterfeit items online?

You can. CBP says it seizes imported goods that violate U.S. laws, and it notes that many small packages from online retailers contain counterfeits. The agency also says individual consumers may be liable for a fine even if they didn't intend to import fakes. Beyond that, you risk losing your money if the order is seized.

Can you bring fake designer items back from a trip?

Only within narrow limits. CBP says travelers may be permitted to bring in one article of each type with a counterfeit mark, once every 30 days, if it travels with them and is for personal use, not for sale. Anything beyond that can be seized. If you sell such an item within a year, it or its value can be forfeited.

How can you tell if something is fake on Amazon?

Check who actually sells the item, not just the brand name in the listing, and look at the seller's name, location and history. Compare the price with the brand's own store and read reviews with some skepticism. When the item arrives, compare packaging, labels and serial numbers with the manufacturer's official information.

How do I know if Apple products are fake?

Check the serial number in Settings under General and AppleCare & Warranty or on Apple's coverage check website, and compare it with the number on the box. For cables and chargers, look for the MFi badge on the packaging. A genuine Apple Lightning to USB cable carries "Designed by Apple in California" and a 12-digit serial number.

Where do I report counterfeit products?

Report the listing through the platform's own reporting tool, and tell the brand if it offers a way to report fakes. CBP's e-Allegations portal accepts reports of suspected trade violations, including counterfeits, from the public. If a fake store took your money, report it to the FTC at ReportFraud.ftc.gov as well.

Can I get a refund for a counterfeit item?

Often, if you paid with purchase protection. PayPal treats an item advertised as authentic that turns out to be counterfeit as Significantly Not as Described, with a deadline of 30 days after delivery or 180 days after payment, whichever is sooner. With a credit card, you can dispute the charge with your issuer. Cash, gift cards and Friends and Family payments are much harder to recover.

Conclusion: to tell if something is counterfeit, look at the whole picture

No single detail exposes every fake. You get a reliable read by combining clues: price and seller before you buy, packaging, labels and workmanship when it arrives, and for electronics, the serial number with the manufacturer. Buying new items directly from the brand or a major retailer avoids most of the problem.

Buying a fake is riskier than it looks. CBP treats counterfeits as illegal, seizes them at the border and warns about health and safety hazards, and reselling fakes can get you into real legal trouble. Pay with purchase protection, save the evidence if something seems off, and report counterfeits where you found them.
