1. Identification method of serial number: domestically developed periodicals are allowed to be distributed at home and abroad, with a unified domestic serial number, and the structural formula of serial number is: CN newspaper registration number/classification number. Only the ISSN international serial number does not have a unified domestic serial number, so it is not allowed to be publicly distributed in China. Some periodicals are printed with CN(HK) or CNXXX(HK)/R, which is not a legal unified domestic serial number. It should be noted that regular periodicals generally have domestic authorities.
In addition to self-issuance, most of them are subscribed through the post office, so there are often postal codes. The standard format of the CN serial number is: CN XX-XXXX, in which the first two digits are the area numbers of provinces, autonomous regions and municipalities directly under the Central Government, and print CN(HK) or CNXXX(HK)/R, which is not a legal domestic unified serial number.
2. Identification of periodicals: If you are in doubt about the legality of newspapers and periodicals, you can consult the Teachers' Section of the Personnel Department or visit the following websites: China Academic Periodical Network, China Anti-vice Network and China Press and Publication Information Network. If you can find it in the periodical query column, it must be a regular periodical.
