The World Association for the Development of Philately (WADP) is an Industry Group working under the aegis of the Universal Postal Union (UPU). It was established by the Director-General of the UPU in 1997.
The major vision of the WADP is to ensure that philately develops, grows and prospers successfully into the next century and beyond. The WADP acts as a strategic forum and central point of reference for the exchange of any information on the numerous aspects of the development of philately.
The WADP Secretariat located at the International Bureau, UPU Headquarters.

as economically and as reliably as possible. With some six million postal employees working
in over 700,000 post offices and mail centers to process and deliver more than
400 billion mail items each year, the postal services of the UPU's 189 member countries
form the largest physical disribution network in the world.
