Courier service


A courier is a person who delivers messages, packages, and mail.

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, OCS, FedEx, EMS International, TNT, UPS, and Aramex. These offer services worldwide, typically via a hub and spoke model.

In ancient history, runners, homing pigeons and riders on horseback used to deliver timely messages. Before the introduction of mechanized courier services, foot messengers physically ran miles to their destinations. As of 2016 there are marathons, based on the Ancient Greek semi-historical narrative of Pheidippides, who is said to have been the runner bringing the news of the Greek victory over the Persians from Marathon to Athens in 490 BCE. In the Middle Ages, royal courts maintained their own messengers who were paid little more than common labourers.
