About Deep Stamp
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. Questions or suggestions? Send feedback directly in the app under Info → Feedback or email [[email protected]](mailto:[email protected]).
What’s new
Version 1.6.0 · Updated October 16, 2026
More stamps, smarter cropping, a tidier history. MORE STAMPS Recognition now covers over 6,000 stamps. New are around 600 stamps from the Old German States — from Bavaria, Prussia and Saxony to Württemberg, Hamburg and Thurn and Taxis — plus hundreds more from West Germany, the German Reich, East Germany and Berlin. Many come with an estimate. The overview now groups the Old German States under a single entry. CROPPING After you take a photo, the app finds the stamp by itself and draws a frame around it. If there are several stamps in the picture, it picks the clearest one — you can move the frame and adjust its corners. Only what is inside the frame is recognised. HISTORY Saved stamps now show the same as the result: name, Mi no., condition and the estimate as a price range. Swipe left to delete a single entry — "Undo" brings it back. Older entries show the time as well. NEW FROM US: PHILAMIND A whole letter or postcard? At philamind.de, PhilaMind gives a philatelic assessment of covers: it reads the stamps, postmarks and markings, checks the postage against the historic rates and shows the route on a map — from the Old German States to West Germany and Berlin (website in German). You'll find the link on the start screen and under "Info". SMALL FIXES Souvenir sheets appear in the history with their proper number, and the rating prompt no longer says "1 stamps".
