About diplomatic courier

A diplomatic courier is an official who secures and transports diplomatic bags. Countries have utilized diplomatic couriers to handle important documents, artifacts and supplies between different countries since the 12th century. Following the 1961 Vienna Convention on Diplomatic Relations, couriers are placed under diplomatic immunity while performing their work. Couriers are usually hired by a specific country and are tasked with protecting and managing bags from being opened. Some couriers are assigned on an ad hoc basis, but in those cases they are released from immunity once their bags have been delivered. The original definition of a diplomatic courier focuses on handling bags, but couriers today also deal with logistical affairs and digital communications.
