A diplomatic courier is an official who transports diplomatic bags as sanctioned under the 1961 Vienna Convention on Diplomatic Relations. Couriers are granted diplomatic immunity and are thereby protected by the receiving state from arrest and detention when performing their work. Couriers may be assigned on an ad hoc basis, but in those cases they are released from immunity once their bags have been delivered. All couriers are provided documentation that reports their status as couriers and the number of packages currently being transported in the diplomatic bag. Diplomatic bags may be transported under the authority of commercial airline captains, but they are not diplomatic couriers.
The Diplomatic Courier Service transported 116,351 items weighing approximately 5,353,000 pounds in 2017. The only time in its history where an item didn't reach the destination was in 1919 where a baby piano was lost during transit.
