How to check whether the company is listed on the Internet and how to check the listing code?

1. Enter the abbreviation of the company in the stock trading system. If found, it is a listed company. If it is not found, it is probably not listed. If the company has been listed, there will be a corresponding stock code after entering the stock abbreviation, which can be viewed directly.

2. Stock codes use numbers to represent different meanings of stocks. Besides distinguishing various stocks, stock code has its potential significance. For example, 600*** is the stock code listed on the Shanghai Stock Exchange, and 6006** is the earliest listed stock. The stock code of a company is similar to the license plate number, which can show the strength and popularity of the company, such as Yantian Port 00088 and Emei Mountain 000888.

3. A listed company refers to a joint stock limited company whose shares are listed and traded on the stock exchange with the approval of the securities management department authorized by the State Council or the State Council. The so-called unlisted company refers to a joint stock limited company whose shares are not listed and traded on the stock exchange.
