About our Product Authentication Service
Is it possible to verify the authenticity of ANY product with Certilogo?
No, only those products that are tagged with a Certilogo Code. Check out which brands use Certilogo. We refer to these brands as "Certilogo-tagged".
What is a Certilogo Code?
A "Certilogo Code" or "CLG Code" is an identification code used to tag products belonging to those brands who have chosen the Certilogo brand protection solution to fight counterfeits. It is a "human readable" code composed of 12 digits usually preceded by the acronym "CLG." Example: CLG 012 345 678 901 or, in some cases, 012 345 678 901.
Where do I find the CLG Code?
The CLG Code can be found in different locations, depending on the type of product. It can be woven into clothing labels, wrapped around the neck of a bottle, or printed on a certificate of authenticity, a hologram or the product's packaging.
I have found the CLG Code on my product, what do I need to do to verify its authenticity?
Simply go to our Homepage and enter the Certilogo Code into the Authenticator, which will ask you a couple of simple questions and tell you if the product is authentic or not.
I have not found the CLG Code on my product. What does it mean?
If your product is on our Brand list, it means that the product is a fake, unless it has been produced before the introduction of the Certilogo-tagging. Please check the brand list to verify.
The Authenticator told me that my product is a fake. What can I do?
Request a Fake Report from us and use it to ask your credit card company, payment service or retailer for a refund. Although laws regarding returns vary, generally you will need to return the item to the seller in its original packaging along with the receipt.
I got the response "Your Product is a Fake". Is there any chance that Certilogo might be wrong?
The Certilogo Authenticator is extremely reliable. If you have provided complete and accurate information and acted according to our Terms and Conditions - see "abuse and improper use" - then your product is indeed a fake, sorry to say. If you think you might have unintentionally provided incomplete or incorrect information, please check again making sure that your data entry is complete and correct.
What is the Certilogo Fake Report and what is it for?
The Fake Report is a document issued by Certilogo upon your request. The document confirms that you verified a product using Certilogo and that that product was identified as a fake by our Authenticator. You can use the Fake Report to claim your money back from those you have scammed you (retailer/seller) or from those who have provided you with the necessary payment service (e.g. credit card company).
Does Certilogo refund me if I have purchased a fake?
No. Certilogo does not sell any products and does not provide any payment services, so we obviously are not responsible for you having unintentionally purchased a fake. If you have unintentionally purchased fake merchandise belonging to brands that are protected by Certilogo (check out which brands are), request a Fake Report (see previous point).
I am shopping online and haven't purchased my product yet. How do I know the advertised product is authentic?
You cannot unless the brand is protected by Certilogo (check out which brands are). If the brand you are shopping for uses Certilogo then you should always buy from the brand's official online store or from an online retailer you know and trust. If you buy elsewhere make sure the seller is displaying the Certilogo-Button on its site, auction or listing. If he doesn't, do not buy because it means that the seller does not care about showing you that he is selling authentic merchandise. If he does display the Certilogo-Button, click it to ensure that the button has actually been issued by us. Remember that the product you'll eventually receive must have the Certilogo Code on it or else it is a fake. So once you receive the product, enter the Certilogo Code into the Authenticator to check that the seller has in fact shipped the promised item and not any other.
For the curious
Is it possible that there are 2 or more items with the same Certilogo Code?
Is it possible to guess a Certilogo Code?
Yes, the likelihood of it being exactly 1 in 1 trillion. It is however impossible to guess a valid code (see next question).
What if someone anyhow manages to guess a code?
A Certilogo Code needs to be "valid", which is linked to specific requirements. For example, an "existing" code must be assigned to a specific product to be also a "valid" CLG Code. It is impossible to guess a valid Certilogo Code.
Is it possible then for a counterfeiter to copy an existing Certilogo Code?
Yes, this is what we refer to as a "cloned code". It is a self-defeating strategy for the counterfeiter because the Certilogo Authenticator is designed to detect those codes. Consumers who check cloned codes will be alerted about the product being a fake.
What if a counterfeiter just copies an existing and valid Certilogo Code from an authentic product and puts it on a fake?
That's what we call a "cloned" code. The Authenticator spots cloned codes thanks to the proprietary anti-fraud methodology developed by Certilogo. Cloning codes is therefore a self-defeating strategy for the counterfeiter because it actually helps us to identify fakes and alert consumers.
