There is no barcode on the trademark registration certificate and you can use your mobile phone to check it. The authenticity of the trademark registration certificate mainly depends on the registration number in the upper right corner. For example, for 22299343, you can directly check the trademark information on the website of the China Trademark Office. There is no need to worry about the trademark registration certificate being forged. All trademark registration certificates will have a trademark registration number. This number is unique and is the one in the upper right corner. It has nothing to do with the barcode. Trademark information can be found. If the information on the trademark website can be matched, it must be true.
