Messengers receive their instructions either by reporting to their office in person or by telephone or two-way radio. They then pick up the item and carry it to its destination. After a delivery, they check with their office and receive instructions about the next delivery. Consequently, most messengers spend most of their time outdoors or in their vehicle. Messengers usually maintain records of deliveries and often obtain signatures from the persons receiving the items.
Most messengers deliver items within a limited geographic area, such as a city or metropolitan area.
Items which need to go longer distances usually are sent by mail or by an overnight delivery service. Some messengers carry items only for their employer, which typically might be a law firm, bank, or financial institution. Other messengers may act as part of an organization's internal mail system and mainly carry items between an organization's buildings or entirely within one building. Messengers reach their destination by several methods. Many drive vans or cars or ride motorcycles.
