WNS, the WADP Numbering System

The WADP Numbering System (WNS) - The world numbering system for postage stamps

Launched in 2002 the WNS had 195 members at the end of 2012.

The WNS is a register of all official postage stamps issued by its members. It is the only system that provides collectors with a guarantee that a given stamp is official.

WNS can therefore serve as a powerful tool to support your marketing strategy, and will help you reach your sales target.
