The UPU is there to help maintain postal communication when a catastrophe occurs. In recent years, the Posts of many countries hit by natural disasters have received funding and emergency assistance to restore postal services quickly. UPU regional coordinators are often mobilized to assess the damage to a country's postal infrastructure and determine how to re-establish service. Relief efforts are closely coordinated with regional postal organizations and United Nations aid agencies on the ground.
The UPU has also set up an Emergency and Solidarity Fund, which provides emergency assistance to revive postal activity in affected areas. Member countries also often generously donate expertise, money and equipment, while others donate financial credits from their Quality of Service Fund resources for specific projects.
