WADP Numbering System
http://www.wnsstamps.ch/en/
The WADP Numbering System (WNS) is a project referencing postal stamps issued in the world since 1 January 2002. It is monitored by the World Association for the Development of Philately (WADP) and the Universal Postal Union. Its inventory is made possible by the declarations of the postal administrations participating to the project.

Its publication appeared on a website where visitors can look for an issue by country, date, topic or key words.

The WNS goals are to give stamp buyers and collectors a stamp catalogue of all official issues and to fight illegal stamps printed without the postal administrations' consent. Since 2002, some developing countries succeeded to reduce their philatelic program and officially denounce illegal stamps via the UPU.
