The Gibraltar Post Office is a department within the Government of Gibraltar. The last decade has seen improvements in several areas like operations, quality of service, e-commerce and services generally, including a next business day delivery model whereby local mail gets delivered or exported the next working day. The department was awarded the title 'Royal' in April 2005 by Her Majesty the Queen Elizabeth II and is now referred to as the 'Royal Gibraltar Post Office' (RGPO). The RGPO, together with the postal operators of most countries in the world, is a member of the Universal Postal Union (UPU), the organisation whose aim is to maintain a universal postal network between all its cooperating members. It provides guidance and common standards (postal performance and technical) which all members are obliged to meet.
