In the 35th category, there are services such as displaying goods in the media for retail purposes, providing business information through websites, publishing online advertisements on computer networks, and providing online markets for buyers and sellers of goods and services, which are in line with some businesses and services of e-commerce and Internet companies, so registration is required.
Category 42 includes: computer software design, development, programming and some services related to websites and search engines, which are also consistent with the services of Internet companies and correspond to the ninth category of goods, so Internet companies will also participate in such registration.
Internet companies, together with the specific services or commodity categories they provide, generally need to register 4-5 categories. For example, Internet companies that provide local life services for fruits should add categories such as fruits in addition to the above three mandatory categories. I hope I can help you adopt it.
