Nowadays, there are many fake Meichao products. Just checking the anti-counterfeiting phone number is no longer enough. Counterfeiting manufacturers can recycle a large number of putty bags with anti-counterfeiting trademarks and fill them with low-quality putty powder to deceive the owners. Steps to identify product authenticity: (1) Observe whether the outer packaging of the product is printed with the registered trademark of Meichao. The registered trademark of Meichao Company is "Mechao", such as "Zhenmeichao", "Meichao" and other names in the past. It is a counterfeit product. (2) Observe whether there is a special national code anti-counterfeiting mark on the outer packaging of the product. All products of Meichao Company are enabled for national code counterfeiting inspection, and you can use the electronic code counterfeiting system to check for counterfeiting. The specific method is as follows: 1. Scratch off the gray coating under the certificate, and you will see two rows of 4 groups of 20 numbers. Use the phone to dial 010-64802566 or 8008303315 to check the authenticity; 2. Connect the phone. You can hear the voice prompt: "The National Anti-Counterfeiting Data Center will verify the authenticity for you. Please use the dual audio phone to enter the anti-counterfeiting number on the product and end with #"; 3. Follow the sequence from left to right and top to bottom. Enter the 20-digit anti-counterfeiting number, and then press the # key; Authenticity reminder: "The product you are inquiring about is a series of Meichao brand products produced by Meichao Decoration Materials Co., Ltd., with the genuine product logo", then the product is authentic. Counterfeiting reminder: "The security code you are querying has been queried on a certain day, month, and year. The security code is invalid. Beware of counterfeiting." or "The security code you are querying has not been registered. Beware of counterfeiting." The product is a counterfeit product. . (3) Observe whether the outer packaging has secondary sealing; if it is secondary sealing, it can be judged as a counterfeit product refilled by unscrupulous traders by recycling Meichao product packaging bags.
