Is there a production date on the hard Chinese cigarette case?

Open the inside of the transparent paper in the upper right corner of the box, and irradiate the anti-counterfeiting logo with ultraviolet light to see the date. The anti-counterfeiting mark uses two letters of the group pattern, with ten digits (divided into two lines) ZH as the Chinese phonetic prefix, and the last ten digits represent the production date, category and car number respectively.

There are 32-bit codes on the cigarette case, each of which has one. The first digit at the beginning is the year, and the second and third digits are the month. When regular cigarettes leave the factory, the specific production date will be clearly marked on the big packaging box and product certificate. However, on every cigarette and box, most manufacturers have not clearly marked it.

Some cigarette manufacturers will have some numbers printed with invisible ink on the outer packaging of cigarette cases, mainly the manufacturer's anti-counterfeiting password.
