For Consumers

What is Certilogo?

Certilogo is the fast, reliable and enjoyable way to confirm that fashion and luxury products with famous brand names are 100% genuine, before or after purchase, using any smartphone or digital device.

What is the Certilogo Code?

The Certilogo Code is your key for a fast and reliable digital authentication with Certilogo, everywhere you shop.

Brands with Certilogo choose their own style of label, hangtag or authenticity card to share a product's Certilogo Code. Popular options and instructions for using them are below: 

NFC
Tap the tag where indicated using a smartphone that reads NFC.

QR
Scan the code with a smartphone camera, QR reader app, or the Certilogo app for iOS or Android.

Numeric
Type the numbers at the URL provided or in the Certilogo app for iOS or Android.

What is The Authenticator?

The Authenticator is the technology that gives you a fast and reliable product authentication with Certilogo. Hosted on the Certilogo platform, and in our app for iOS and Android, The Authenticator uses state-of-the-art machine learning and image recognition technologies to determine in seconds if a brand-name product is 100% genuine.

Why should I authenticate my product?

Because it's the smartest and simplest way to be sure that an item with a brand name logo was actually manufactured by that brand.
Buying authentic makes sure you get your money's worth and a product backed by a reputable brand. It also gets you access to digital content selected by the brand and the satisfaction of knowing your purchase supports the creators and designers who bring the brand to life. 

Where is the Certilogo Code?

Brands with Certilogo choose their own location and style of label, hangtag or authenticity card to share a product's Certilogo Code.

Look for the letters CLG and 12 numbers — CLG 000 000 000 000 — next to a set of printed instructions like "Check authenticity at www.certilogo.com" or "Connect with your authentic product at www.certilogo.com".

Some brands also use an NFC or QR code for faster access. Use your smartphone to tap the NFC tag or scan the QR code and begin your authentication. 

Can a Certilogo Code be used more than once?

Absolutely. When used properly, a Certilogo Code is good for the life of a product and can be verified as often as needed.

For best results, pre-purchase users should choose the answer "In a store", when asked where the product was found, and "No" when asked if the product has been purchased.

Can I share my Certilogo Code with friends who want to try it?

Invite them to visit us for a demo instead. Once a product is yours, sharing the Certilogo label with friends or online creates an irregular pattern of authentication that makes our Artificial Intelligence suspicious. When that happens, the code response changes from Authentic to Something's not right.

Can two products have the same Certilogo Code?

Not two authentic products. 

Copies or replicas of brand labels are used by counterfeiters who want to make their fakes look real, but these don't fool the online verification. A cloned or replica code entered for verification will return the answer Fake.

What is the Certilogo Seal?

The Certilogo Seal is a fast and reliable method to confirm that a product for sale in an online marketplace is authentic. 

Sellers with an authentic product request the Seal from Certilogo and post it in a listing. Buyers use a smartphone to scan the QR code, or enter the 12-digit code at the URL provided, to begin the authentication process.

A Seal that is genuine and registered with Certilogo will give the answer Authentic. A Seal that is copied or invented by a dishonest seller will respond with the answer Fake.

How do I use the Certilogo Seal as a buyer?

Simply scan the QR Code with a smartphone or type the code digits (CLG 000 000 000 000) at the URL provided and answer the questions on your screen.

An authentic Certilogo Seal will respond with the answer Authentic. A Seal that has been copied or invented by a dishonest seller will respond with the answer Fake.

What is the Certilogo Fake Report?

The Fake Report is a complimentary written record that helps you to file a complaint and ask your credit card company, payment service, or retailer for a refund. 

Remember that laws about returns will vary so be sure to check the guidelines where you made your purchase. In most cases you will be asked to return the item in its original packaging, with a copy of your receipt.

How do I get a Certilogo Fake Report?

When a product is not genuine, the authentication process will end with the response Fake and buttons for more actions. Select the button Request a Fake Report.

If the button does not appear, contact our customer care team at help@certilogo.com, or by clicking the link below, and explain that you need the Fake Report.

For fastest service, attach at least two clear, close photos of the product and the Certilogo label or hang-tag. 

 

How long until I receive my Fake Report?

The Certilogo Fake Report will be sent immediately after you complete the required form, to the same email address that you used when you registered with the service.

Does Certilogo refund my money?

No. The Certilogo Fake Report is a complimentary service to help you get a refund from your credit card or payment service, or from the person, store, or e-commerce site that sold you the product.

What is Instant Authentication?

We trained Certilogo's Artificial Intelligence engine to recognise selected images of authentic luxury handbags.

Photos you submit are analysed to detect complex patterns that are only present when a handbag is authentic, all in seconds or less.

We've made Instant Authentication available to the public in a Beta version so we can test and perfect it with feedback from real handbag lovers. Try it today for an authentication result in seconds at no cost.

What photos do I need?

After you register we'll guide you to shoot and upload a small number of close, clear, well-lit photos of features on the handbag, based on the brand. 

If you'd prefer to plan ahead, photograph anything that makes the bag distinctive — brand logos, "made in" labels, date codes, serial codes, holograms, authenticity cards, and hardware — and we'll guide you to upload the ones we need from your photo roll.

Can I upload photos from a seller?

Certainly. We recommend that sellers authenticate the bag for themselves first to ensure their photos are accepted for Instant Authentication. 

Eligible images can then be shared in online listings or passed directly to a potential buyer who wants to upload them in The Authenticator and see the result in person.

Buyers who purchase online are advised to shoot and upload new photos when their purchase arrives to verify that the seller shipped the same authentic item.

Why can't I post a photo of my Certilogo tag instead of the Certilogo Seal?

Scanning or entering the code from a Certilogo tag launches an authentication process that is designed for a person with the product in hand. That's no help to someone shopping online.  

The Certilogo Seal of Authentication, on the other hand, is specifically designed for reselling your product online. Answers are fast and reliable for buyers, so your items sell faster and at better prices.
