May I use my FedEx Express account number for TNT services and vice versa?

Account numbers can only be used for services from the individual company that issued them. FedEx Express and TNT will continue to provide services as they do today. There are no immediate changes to how you manage your account, billing or invoicing.
However, if you would like to start using services of either company, we welcome your business. Please contact the appropriate customer service team to open your account.
