Picture a counterfeit and you probably see a fake designer bag on a beach blanket, or sneakers with a slightly wonky logo. Those exist. They're also not the fakes that put people in the emergency room. The ones that do real harm look boring: a $9 phone charger, a power bank, a jar of face cream, a replacement airbag, a smoke alarm that never makes a sound. Most are bought from a marketplace listing that looked perfectly normal.
To tell if a product is fake, check who is actually selling it, compare the price with the brand's authorized retailers, and read the listing and reviews for mismatches. When it arrives, compare packaging, seals, batch codes and serial numbers with the brand's official photos. If it's fake, claim through the platform or your card before the deadline.
How to tell if a product is fake before you buy
Most people check the price first. That's the wrong order. Counterfeiters learned long ago that a 90% discount scares buyers off, so many now price a fake just under the going rate, enough to look like a coupon rather than a miracle. The seller tells you far more than the price does.
- Find out who is really selling it. On Amazon, the small print beside the Buy button says who ships the item and who sells it. Walmart.com and Target.com show a similar "sold by" line. If it's a third-party name, click it before anything else.
- Check the brand's authorized retailers. Most electronics, beauty and tool brands publish a "where to buy" page. A seller missing from it isn't automatically selling fakes, but you're outside the brand's warranty and quality control.
- Compare the price with those stores. A current product far cheaper than every authorized store, with no sale to explain it, is a warning.
- Read the listing like an editor. Odd spellings of the brand, no model number, only stock photos, and words like "AAA", "1:1", "mirror quality" or "inspired by" are giveaways.
- Read the newest bad reviews. Search one- and two-star reviews for "fake", "smells different", "batch code" or "not genuine". A few specific complaints outweigh hundreds of vague five-star ratings.

The counterfeits that can actually hurt you
A fake handbag costs you money. A fake charger can cost you a house. The OECD and the EU's intellectual property office put it plainly in their 2025 report: counterfeits lack any safety testing, and when something goes wrong there's no responsible company to hold to account.
Chargers, power banks and batteries
In June 2026 the UK consumer group Which? bought 15 USB phone chargers from online marketplaces and had them tested. Nine were so poorly built that a user could get an electric shock, and eight of those were also a fire risk. All 15 lacked legally required information such as the importer's address, and two were stuffed with modelling clay to feel solid in the hand. A 2016 Trading Standards test found 397 of 400 fake Apple chargers failed a basic safety test. Buy chargers, power banks and e-bike batteries from the device maker or a retailer it names.
Electrical goods and alarms
Safety marks are just ink. Anyone can print a UL, ETL, CE or UKCA logo on a box. A counterfeit smoke or carbon monoxide alarm is the cruelest fake because it fails silently: the test button checks the horn and electronics, not whether the sensor detects smoke. Buy alarms from hardware stores or the maker's listed retailers, and check certifications in the certifier's own database (UL's is called Product iQ) rather than trusting the sticker.
Car parts, toys and protective gear
The OECD/EUIPO report flags counterfeit car parts as a growing problem, with the average seized fake spare part now worth more than $300. Industry testing it cites found counterfeit airbags, nicknamed "zombies", often fail to deploy. If a car has had an airbag replaced, ask the shop for the parts invoice. Fake toys, helmets and safety glasses skip the testing the genuine versions paid for, and US Customs seized 880,546 counterfeit toys in fiscal 2025 alone. Recalled parts are a separate issue, covered in our recall guide.

How to tell if skincare or makeup is fake
Beauty is where the odds are worst. When US Government Accountability Office investigators bought everyday goods from third-party sellers on popular websites in 2018, all 13 cosmetics turned out to be counterfeit, against none of the 15 pairs of shoes. The Personal Care Products Council, the US cosmetics trade group, cites government reports of fake beauty products containing arsenic, cadmium, mercury and high levels of bacteria. You can't see any of that, so check what you can see.
- Batch codes match. The code printed or embossed on the tube or bottle should match the one on the carton. A missing code, or a stuck-on sticker instead of print, is a bad sign.
- Seals are right. Expect tight, neatly folded cellophane or a branded tamper sticker, and often an inner foil seal under the cap.
- It matches one you know is real. Compare texture, color, scent, pump action and how the cap clicks shut. Fakes are often runnier, grainier or more heavily perfumed.
- The ingredient list matches the brand's site. Counterfeiters copy old packaging, and misspelled ingredient names are common.
- The seller is a listed stockist. Whether you're asking about CeraVe, The Ordinary or rhode, open the brand's own "where to buy" page and check the seller against it.
Batch-code decoders show when a product was made, not who made it. If something burns or causes a rash, stop using it. In the US, report the reaction to the FDA through MedWatch or on 1-888-723-3366, option 4; in the UK, report the seller to Trading Standards through Citizens Advice. Fake medicines and injectable weight-loss pens need different checks, covered in how to spot fake medicine.
How to tell if an Amazon seller is legit (and spot fake reviews)
Amazon listings come in three flavors. "Ships from Amazon, sold by Amazon" means Amazon bought the stock itself. "Ships from Amazon, sold by" another name means a third-party seller stores its own stock in Amazon's warehouses. "Ships from and sold by" the same third-party name means the seller handles everything. Most third-party sellers are legitimate, but this is where counterfeits get in. Amazon says it identified, seized and disposed of more than 15 million counterfeit products in 2024.
Click the seller's name to see its storefront, its feedback score, how many ratings that score rests on and, for US sellers, a business name and address. A store with a few dozen ratings selling hundreds of famous-brand products deserves a second look.
One more wrinkle: Amazon used to pool identical units from different sellers who used the manufacturer's barcode, called commingling, so your unit could come from another seller's stock. Amazon told sellers it would end commingling for inventory sent in from March 31, 2026, with older stock allowed to sell through.
Signs that Amazon reviews are fake
Watch for a burst of five-star reviews within a few days, praise so generic it could describe anything, reviews describing a different product (a sign of merged listings), and lines like "I received this at a discount in exchange for my honest review". Sort by most recent, because an old listing can be taken over by a new seller. The rules have tightened: the FTC finalized a rule in August 2024 banning the buying, selling or writing of fake reviews, including AI-generated ones, and the UK banned fake reviews from April 6, 2025, making websites responsible for the reviews they host.
Spotting fakes on eBay, Facebook Marketplace, Vinted and TikTok Shop
The photo is the biggest tell. A private seller who only uses the brand's stock images may not have the item, or may have something different. Ask for a photo of the actual item beside a note with your name and today's date.
- A "private" seller with the same item, new with tags, in every size and color.
- A price far below recently sold listings for the same model, not just below asking prices.
- "Authentic" or "100% real" in the title, with no receipt, box or proof of purchase.
- Requests to pay outside the app, which strips away buyer protection.
- Livestream pressure on TikTok Shop for a prestige product from a shop that isn't the brand's official store.
eBay's Authenticity Guarantee covers sneakers, handbags, watches, jewelry, streetwear, trading cards and coins: listings with the badge are examined by professional authenticators before the item reaches you. On Vinted and Facebook Marketplace, pay through the app's own checkout to keep its protection. Cash on local pickup leaves you with none, so inspect before you pay.
Counterfeit vs dupe vs gray market: what's the difference?
"Fake" covers several things, and the difference matters for your rights.
| Type | What it is | Legal to sell? | Warranty |
|---|---|---|---|
| Counterfeit | Copies a brand's name, logo or packaging to pass as the real thing | No, it infringes the trademark | None |
| Replica | A counterfeit sold openly as a copy ("AAA", "1:1") | No, if it carries the brand's marks | None |
| Dupe or knock-off | A similar look or formula under its own brand name | Usually, unless it copies protected designs | From its own maker |
| Gray market | Genuine goods sold outside authorized channels, often a version made for another country | Often, with limits | May be refused by the brand |
| Refurbished | A genuine used product repaired and resold | Yes, if described honestly | Depends on the refurbisher |
On social media, "dupe" sometimes means an honest look-alike and sometimes a wink at a fake. If the original logo is on it, it's a counterfeit, whatever the caption says.
How to check if a product is original when it arrives
Check the day the parcel arrives, before using the item and while claim windows are open. Film the unboxing of anything expensive.
- Print and packaging. Compare fonts, colors, logo position and spelling with photos on the brand's own site. Blurry print and thin cardboard are common giveaways.
- Serial numbers agree. On electronics, the serial on the box, on the device and in its settings menu should match.
- Ratings and importer details. Chargers and plugs should show exact input and output ratings and a maker's or importer's name and address.
- Materials and finish. Check stitching, zips, hardware, engraving depth and the feel of plastics.
- Weight, used carefully. Much lighter than the listed weight is suspicious, but heavy isn't proof. Some fake chargers are weighted with clay.
- Manuals and inserts. Poor translations, a missing manual or a QR code leading anywhere but the brand's website are warning signs.
If anything fails, stop using the item, keep it with all its packaging, and photograph every mismatch. That evidence carries your refund claim.
How to verify a serial number or authenticity code with the brand
Many brands let you check a serial number for warranty coverage. A serial that comes back invalid, or as a different model or color, is a strong sign of a fake. A serial that checks out proves less than people think, because counterfeiters copy one real serial onto thousands of units.
Scratch-off codes and QR stickers only mean something if you verify them on the brand's own domain, and a one-time code that says "already verified" is a warning, not a pass. Scan any QR code on a package with our QR code scanner first to see the full address it opens. Holograms aren't proof either: in 2016 UL warned that genuine holographic safety labels had been stolen from a factory and could turn up on untested products.
Barcodes identify a product, not the factory that made your unit. Our barcode checker shows whether a number is valid and which product it belongs to, which exposes fakes whose code belongs to something else. Our guide to what barcode numbers mean explains why a match isn't proof.
Is it illegal to buy counterfeit goods?
In the United States, selling counterfeits is a federal crime, but buyers are rarely prosecuted for personal purchases. The goods can still be seized. Federal rules let a traveler bring in one article of each type bearing a counterfeit mark if it travels with them for personal use, no more than once every 30 days, and it can be forfeited if sold within a year. Parcels you order don't travel with you, so that allowance doesn't cover them.
Europe can be stricter. French customs treat possession of counterfeits as a customs offence: the goods are confiscated, the fine runs from one to two times the value of the goods, and the law allows up to three years in prison. In the UK, buying a fake for yourself isn't generally an offence, but selling one is. For a specific case, ask a lawyer or your customs authority.
I bought a fake: how to get your money back
Use the platform's guarantee first; it's usually faster than your card company. Don't run both at once: Amazon says that asking your payment provider for a chargeback makes you ineligible for an A-to-z Guarantee refund. These deadlines come from each company's published policy as of November 2026.
| Where you paid | How to claim | Deadline | Counterfeit rule |
|---|---|---|---|
| Amazon (third-party seller) | Request a return; if it isn't authorized after 48 hours, file an A-to-z Guarantee claim | Within 90 days of the last possible delivery date | Covers items damaged, defective or materially different from the listing |
| eBay | Return request; ask eBay to step in if the seller doesn't fix it within 3 business days | 30 days after delivery | With strong signs of counterfeiting you may not need to ship it back, and you must not resell it |
| PayPal | Open a Significantly Not as Described dispute | 30 days after delivery or 180 days after payment, whichever is sooner | Explicitly includes items advertised as authentic that are counterfeit |
| Visa card | Ask your card issuer to dispute it as counterfeit merchandise | 120 days from the charge, delivery or the date you were told it was fake (max 540 days) | Needs confirmation from the brand, a customs or government agency, or a third-party expert |
That last row trips people up. Under Visa's rules, the counterfeit dispute needs the item identified as fake by the brand or its representative, a government agency, or a third-party expert, so an email from the brand's anti-counterfeiting team is gold. Without it, your bank may use "not as described" instead. Other card networks have their own rules, so ask your issuer. Our recovery planner sets out the steps. If a seller insists you post the item back overseas at your own cost, read about that trap in our fake online store guide first.
The brand's confirmation that an item is fake is the single most useful document in a counterfeit claim.
How to report counterfeit products
Start with the platform's "report" option on the listing or order. Then email the brand's anti-counterfeiting team, usually listed on its legal or "report a fake" page. They can confirm the fake and often have more power to remove sellers than you do.
In the US, report counterfeiting to the National IPR Coordination Center through its referral form or via STOPfakes.gov, report dangerous products to the Consumer Product Safety Commission at SaferProducts.gov, and report cosmetic reactions to the FDA. In the UK, Citizens Advice passes reports to Trading Standards, which can act against the seller but won't recover your money. In the EU, national customs and consumer authorities take reports. Our report a scam page lists where to go by country.
How big is the counterfeit trade?
The OECD and EUIPO estimate that trade in counterfeit goods was worth about $467 billion in 2021, or 2.3% of world imports. For the European Union the share was higher: $117 billion, or 4.7% of all imports. China and Hong Kong remain the main sources, and in 2020 and 2021 almost 60% of seized fake items traveled by post.
US Customs and Border Protection seized 78.4 million counterfeit items in fiscal 2025, worth $7.4 billion had they been genuine and more than double the previous year's item count. After the US suspended duty-free de minimis shipping (for China and Hong Kong in May 2025, for all countries that August), counterfeiters moved from small parcels into containers: 62% of fiscal 2025 seizures happened in sea cargo. In the EU, authorities detained about 196 million counterfeit goods worth an estimated €6.3 billion in 2025, a record value. The European Commission notes that counterfeiters ship labels and packaging separately and assemble the fakes inside the EU.

Frequently asked questions
Can you tell if a product is fake by the barcode?
Not on its own. A barcode identifies a product, not the factory that made the unit in your hand, and counterfeiters copy genuine barcodes all the time. A barcode check is still useful the other way round: if the number is invalid, belongs to a different product or size, or does not exist at all, that is a strong warning sign. Treat a matching barcode as neutral and a mismatched one as a red flag.
Does Amazon sell fake products?
Counterfeits do reach Amazon customers, mostly through third-party sellers. Amazon says it identified, seized and disposed of more than 15 million counterfeit products in 2024, which shows both the effort and the size of the problem. Items listed as shipped and sold by Amazon carry the lowest risk. For anything sold by a third party, check the seller and the brand's list of authorized retailers before you buy.
Are Amazon Resale (Warehouse) deals real products?
They are usually returned, open-box or lightly used items that Amazon resells, so the product itself should be what the original buyer received. That is also the catch: if someone returned a fake in place of a genuine item, it can end up back in stock. Inspect open-box electronics and beauty products the day they arrive, check serial numbers with the brand, and return anything that does not match.
How do I check if a perfume is original?
Start with the box: genuine perfume boxes are tightly wrapped in cellophane with neat folds, and the batch code printed on the box should match the code on the bottom of the bottle. Compare the cap, the sprayer and the bottle glass with photos on the brand's own site. Fakes often smell right for a few minutes and then fade or turn sharp and alcoholic. Buy from stores the brand lists as stockists.
Are products from Temu or AliExpress counterfeit?
Most items on those platforms are unbranded or private-label goods, not counterfeits. The risk rises sharply when a listing uses a famous brand name, logo or product design at a fraction of the normal price, because genuine branded goods are rarely sold that way. For safety items such as chargers, batteries and alarms, an unbranded product with no importer details or certification can be as risky as a fake.
What does commingled inventory mean on Amazon?
Commingling meant Amazon could pool identical units sent in by different sellers under the same manufacturer barcode, then ship whichever unit was closest to you. Your order could therefore come from another seller's stock. Amazon told sellers it would stop commingling for inventory sent to its warehouses from March 31, 2026, with older stock allowed to sell through, so the practice is fading rather than gone overnight.
Can customs seize counterfeit items I ordered online?
Yes. US Customs and Border Protection can seize counterfeit goods at the border, including small parcels, and you will normally get a notice by mail rather than your item. The personal-use allowance for travelers applies to goods that arrive with you, not to things you order by post. In the EU, customs can detain parcels too, and some countries such as France can also fine the buyer.
How can I tell if a phone charger is fake?
Check for the brand's exact model number, input and output ratings, the importer's name and address, and certification marks with matching file numbers. Spelling mistakes, a price far below the brand's own store and no box or manual are warning signs. Do not rely on weight: Which?'s 2026 tests found fakes weighted with modelling clay. If in doubt, buy chargers from the phone maker or a major retailer.
Do authenticity cards and holograms prove a product is real?
No. Cards, stickers and holograms are cheap to print, and counterfeiters copy them along with the packaging. Even genuine security labels can be stolen and stuck on unsafe products, which UL warned about in 2016. A label only proves something if you can verify its code on the brand's own website and the result describes the exact product you are holding.
What should I do if I received a counterfeit item on eBay?
Open a return request in your eBay purchases within 30 days of delivery and choose the reason that says the item does not match the listing, explaining why you believe it is counterfeit and adding photos. Under eBay's Money Back Guarantee you may not have to ship a suspected fake back. Do not resell it. If the seller does not fix it within three business days, ask eBay to step in.
Can I resell a fake I bought by mistake?
No. Selling counterfeit goods is illegal in the US, the UK and the EU even if you were fooled yourself, and marketplaces ban it. eBay and PayPal both make refunds for counterfeits conditional on the item not going back into circulation. Keep it as evidence until your claim is settled, then dispose of it as the platform or brand tells you.
