Stampium is a mobile application that helps you identify postage stamps using artificial intelligence. Simply take a photo (or upload an existing image) of a stamp, and the app will analyze it to provide the most likely match, an AI-generated description, and additional reference images of similar stamps.
Our AI-powered algorithm analyzes visual features of your stamp photo—such as country of issue, year, denomination, design motif, color, perforation style, printing technique, paper type, and overall appearance—to match it against a large stamp reference database. The app then suggests the most probable match and provides a detailed AI-generated description.
For the most accurate identification, use clear, well-lit photos where the stamp lies flat and fills most of the frame. Make sure the perforations are fully visible and avoid blur, glare, and heavy shadows. If possible, capture both sides (front and back) and keep the camera parallel to the stamp for the sharpest image.
Yes! You can either take a new photo directly in the app or upload an existing image of a stamp from your device's gallery for identification.
Stampium uses advanced AI algorithms and a large stamp reference database to provide accurate results in most cases. However, identification is not always perfect—especially for damaged or heavily used stamps, very old or rare varieties, or stamps photographed in poor lighting. Please use results as a helpful guide and consult a qualified philatelist or stamp dealer for critical decisions.
For each identified stamp, you may receive an AI-generated description, country of issue, year, denomination, design theme, perforation type, printing technique, catalog references, and additional reference images to help you compare and learn more. Value estimates (if shown) are informational only and can vary widely based on condition, centering, gum status, rarity, and demand.
Your privacy is important to us. When you use the app, your photo is securely sent to a third-party service for identification purposes. Additionally, we store the photos you provide so that you can conveniently view your identification history within the app. You can delete your history and associated photos at any time through the app's interface. We do not share your photos with any other parties beyond what is necessary for stamp identification. Please see our Privacy Policy for more details.
Stampium requires an internet connection to process images and access the stamp reference database. Offline identification is not currently supported.
If the app cannot confidently identify your stamp, try taking clearer photos (ideally of both sides), improving lighting, and ensuring the perforations are fully visible in the frame. You can also use the app's suggestions to explore similar matches or consult a philatelist or stamp catalog for further assistance.
Stamp descriptions in the app are generated by artificial intelligence based on reference information and structured data sources.
