Not necessarily a legal person because Amazon does not stipulate that only legal persons can register to open a store. Individuals can also register to open a store. But if you want to operate in the name of a company, you must register as a legal person. In addition, in order to ensure transaction security, Amazon has certain requirements for the qualifications and financial status of the personnel who register to open a store, and you need to provide relevant supporting documents. It is worth noting that if you want to register as a company to open a store, you need to have certain conditions such as funds and identity proof, and you must also bear the company's risks and related legal responsibilities. Therefore, if you just want to sell some small commodities on Amazon or engage in self-employment, it is also possible to register as an individual.
