A product corresponds to an anti-counterfeiting code, and all anti-counterfeiting codes are unique, encrypted and valid for a single query. Some products may not have security codes.

Anti-counterfeiting codes are generally composed of numbers and letters, which are usually located on the packaging and coated. The serial number of some electronic products can also be used as anti-counterfeiting code (the package is invisible and undamaged, so it must be hidden), and some low-cost packages will use barcode and QR code as anti-counterfeiting code (each code is unique, but only exposed).

If the purchased product has an anti-counterfeiting code, you can inquire according to the phone number and website prompted by the product. If it can be found and displayed as the first query, it is genuine. There are generally four ways to inquire about security codes: telephone inquiry, short message inquiry, website inquiry and manual service desk. It is most convenient to inquire in official website. If the displayed security code has been inquired or cannot be inquired, the purchased goods are not genuine.

If the product has no anti-counterfeiting code, it cannot be completely determined that the product is a counterfeit product. Generally, the old batch of products may not contain anti-counterfeiting code, so you need to check the announcement in official website or call the official manual service desk for confirmation. If the same product has exactly the same appearance and packaging, and the genuine product has an anti-counterfeiting code, but the customer does not have an anti-counterfeiting code when buying it, it is generally a counterfeit product.
