Know what your stamps are, and what they’re not worth.
Take a photo of one stamp or a whole album page. Stamp Lens shows the closest matches from its catalog, says how sure it is, and gives value ranges it can explain.
- No ads, ever
- No account needed
- Whole album pages
Built for the box of stamps you just inherited
And for the collection you have been building for years.
Scan a whole album page
Up to 40 stamps in one photo. Remove a wrong box or add a missed one, then identify them all and get a page summary.
Top 3 matches, not a guess
When we are not sure, we say so. Pick the closest of three candidates, each with a confidence level and a reference picture.
Same photo, same answer
Results come from a real stamp catalog, so rescanning the same photo gives the same result.
Your own catalog numbers
Add your Scott, SG, Michel or Yvert number to any stamp. It stays on your phone.
Albums, wishlist, history
Save stamps into albums, keep a wishlist, and reopen any scan from the last 90 days.
Export for selling or insurance
A clean CSV or PDF of your collection with photos, ready to share. Part of Pro.

Most stamps are worth a few cents. We will tell you.
No $4 to $1,500 ranges. When Stamp Lens shows a value, you see why.
- A narrow range with a confidence level and the reason behind it
- Never a range wider than 10 times: above that we say it needs an expert
- A gentle “worth a closer look” flag when a stamp may be valuable
- Values come from our own data, never from a publisher’s catalog or an AI guess

Questions people ask
How does Stamp Lens identify a stamp?
The app finds and crops each stamp on your phone, then sends only those crops to our server. The server compares the crop with the images in our own stamp catalog and returns the closest matches. For hard cases a vision AI model may compare your crop with those catalog candidates and read the text and face value. It picks from real catalog entries; it never invents one or names a price.
Why do I sometimes get three choices instead of one answer?
When we are not sure, we say so. You see the top three candidates with a confidence level and a reference picture, and you pick the right one (or None of these). Your pick helps us improve the catalog.
Will the same photo give a different answer next time?
No. Results come from our catalog, not from a guess, and a rescan of the same photo returns the same answer.
Can I scan a whole album page?
Yes. Lay the album flat and shoot from directly above. The app finds up to 40 stamps on the page, lets you remove or add boxes, then identifies them all and gives you a page summary.
How much are my stamps worth?
Most common stamps sell for a few cents. When Stamp Lens shows a value, it is a range with a confidence level and the reason behind it, never a range wider than 10 times. If a stamp may be valuable, we flag it and suggest getting an expert opinion. Values are estimates only, not an appraisal.
Why are there no Scott, Stanley Gibbons or Michel numbers?
Those numbering systems and their prices belong to their publishers, so we don't copy them. You can type your own catalog numbers into any stamp; they stay on your phone.
Do my photos leave my phone?
Your full photo stays on your phone. Only the cropped stamps, with location and other photo metadata removed, are sent when you tap scan. Your collection is stored on your device.
