Anti-counterfeiting codes are generally composed of numbers and letters, usually located on the packaging and coated. The serial numbers of some electronic products can also be used as anti-counterfeiting codes (packaging must be hidden unless it is damaged and invisible). If the coating of the security code cannot be scraped off, it is likely to be a forged security code or a counterfeit product. You can go to official website to inquire about the product (you can see the inquiry record). If the displayed security code has been found or cannot be found, the purchased goods are not genuine.
