What stamp is this? Simply take a photo — Stamp Scanner uses AI to identify German stamps and gives you the Michel number, collecting area, and condition in seconds. Completely free, with no account, no ads, and no subscription. HOW IT WORKS 1. Take a photo of the stamp with your camera or choose an image from your photo library 2. The AI analyzes the image and identifies the stamp 3. View the result: Michel number, region, year of issue, and whether the stamp is unused or cancelled FEATURES • Identify more than 4,000 German stamps — from the German Empire to modern Germany • Condition detection: distinguishes between unused and cancelled stamps • Catalog details for the identified stamp, including a reference image for comparison • History: all scanned stamps remain saved on your device • Automatic cropping: the app detects the stamp in the image automatically SUPPORTED COLLECTING AREAS German Empire, Allied Occupation, Saarland, Berlin, East Germany (GDR), and the Federal Republic of Germany (FRG). GOOD TO KNOW Identification is an AI-based estimate. It is fast and continuously improving, but it can occasionally be wrong. It does not replace expert philatelic authentication and does not provide a value estimate. Wrong result? Submit a correction with one tap and help improve the recognition system. YOUR DATA • No account, no registration, no tracking, no ads • Photos are uploaded only for identification and deleted afterwards • Images are stored permanently only if you explicitly agree when submitting feedback WHO IS IT FOR? For collectors organizing an album or collection. For heirs who want to know what they have inherited. And for anyone who wants to quickly identify a stamp found at a flea market or elsewhere.
