A product will have an anti-counterfeiting code, and all anti-counterfeiting codes are unique, encrypted and valid for a single query.
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.
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. Generally, it is the most intuitive and quick to inquire about products in official website, which is recommended. If you can't find the security code information, it means that the product is probably a counterfeit product, or it may be a system problem (you need to find the manual service desk to confirm).
