No, it is not strictly necessary to have an account with FedEx to ship internationally. Individuals and businesses can use FedEx services without an account by visiting a local FedEx office or authorized shipping location. In such cases, customers can complete the shipping process by providing their package information and paying for the shipping services at the time of shipment. However, having a FedEx account can offer several benefits, such as the ability to easily track shipments, access to discounted rates, streamline the shipping process, and manage all shipping activities in one place. For those who ship frequently, creating an account may prove to be advantageous. For more information about account options, including how to create one, customers may want to refer to the FedEx website for details.
