Business licenses generally fill in the company's certificate type. The business license is a certificate issued by the administrative department for industry and commerce for the legal operation of an enterprise as a legal person or individual industrial and commercial households. It contains the basic information of an enterprise, such as its name, registered capital and business scope. When conducting business activities, it is often necessary to provide a company certificate to prove the legitimacy and identity of the enterprise. Therefore, when filling in the company's certificate type, the business license will generally be selected as a valid proof document.
