If the business license of an individual industrial and commercial household has a trade name but does not have a trade name, it means that it has a store name or no store name. The specific details are as follows:
1. According to the "Measures for the Administration of Name Registration of Individual Industrial and Commercial Households", An individual industrial and commercial household does not need to use a name. If the individual industrial and commercial household decides to use a name, these Measures shall apply to the registration of the name. Therefore, individual industrial and commercial households can have a store name, or they can not afford a store name.
2. The business license of an individual industrial and commercial household may or may not use a font size. However, if an individual industrial and commercial household decides to use a font size, it can only use one font size, and must apply to the relevant registration authority before it can be used after approval and registration.
So, if the business license of an individual industrial and commercial household has a font size but does not have a font size, it means that it has a store name or no store name.
