The Universal Postal Union (UPU) has launched the new WNS app, making stamp identification easier, faster and more accessible than ever before. With a user-friendly interface and AI-supported image recognition, the application allows users to search and identify stamps registered in the WADP Numbering System (WNS) database.
The app, available for iOS and Android, grants access to nearly 120,000 officially issued stamps from nearly 200 UPU member countries and territories. As the only global stamp database based entirely on official data submitted by issuers themselves, the WNS plays a crucial role in protecting collectors and the global multi-billion-dollar philately market from counterfeiting.“For collectors, the app will be a game changer”, said Benjamin Combes, Manager of the UPU’s Philately Development and Documentary Heritage Programme. “Before, identifying a stamp could be a time-consuming process involving catalogues and research. Now, with a simple scan, users receive detailed, verified information within seconds.”
In addition to providing immediate access to stamp data, the app protects user privacy by not requiring an account and not collecting personal data. Upcoming updates will introduce features such as social media sharing and real-time market value indicators. The UPU also plans to expand language support to reach a truly global audience.
The app’s development has led to broader enhancements of the WNS database. New metadata fields, including printing techniques, artists, engravers and issue quantities, are being added to enrich the collector's experience. The UPU is also addressing historical gaps by allowing Posts to pre-register stamps issued between 1840 and 2001 via a dedicated platform.
By bridging tradition with innovation, the WNS not only empowers collectors worldwide but also helps postal operators to connect with international markets and promote philately among younger generations.
