What is the patent number of Jobozi mask?

After the patent applicant obtains the patent right, the patent number on the patent certificate issued by China National Intellectual Property Administration is ZL (patent initials)+application number. If a patent is being applied, but the ZL letter is added before the application number (making consumers mistakenly think it is an authorized patent), it is a counterfeit patent and the administrative department for industry and commerce will investigate and deal with it according to law.
