What is Courier?
2016/3/7 17:48:40
Couriers are distinguished from ordinary mail services by features such as speed, security, tracking, signature, specialization and individualization of express services, and swift delivery times, which are optional for most everyday mail services. As a premium service, couriers are usually more expensive than standard mail services, and their use is normally limited to packages where one or more of these features are considered important enough to warrant the cost.
Courier services operate on all scales, from within specific towns or
cities, to regional, national and global services. Large courier companies include DHL, FedEx, EMS International, TNT, UPS, and Aramex. These offer services worldwide, typically via a hub and spoke model.
