The fund code, like the stock code, is a unique number string, which only represents a certain charging mode of a fund. Whether we are buying or selling funds or searching for funds, it will be easier to remember codes or count a few numbers.
When investing in a fund, the name and code are also corresponding to prevent buying the wrong fund. In addition, even for the same fund, different charging models and codes can be different. So in general, the fund code only represents a fund.
