Amazon is not just a transportation company, it is also one of the world's largest e-commerce platforms. It has its own logistics system, including Amazon Logistics, which provides global transportation services for sellers on the platform. In addition, Amazon also provides a series of other e-commerce and logistics related services, such as FBA (Amazon Logistics), Prime membership, Alexa smart home, etc.

Therefore, although Amazon has its own logistics services, and these services are an important part of its e-commerce business, it may not be accurate to call Amazon a transportation company because it is more widely involved in e-commerce, cloud computing, content production and other fields.
