How to Identify a Stamp by Photo
A careful photo and a quick result check produce the most useful starting point.
2. Review the match
Check the country, year, denomination and design before relying on the result.
3. Research the estimate
Compare condition and authenticity, then verify important finds with a specialist.
What the Stamp Identifier Can Show
The app is designed to shorten the first stage of stamp research. It does not replace physical inspection, a specialist catalogue or professional authentication.
Likely country or postal authority
Estimated issue year and denomination
Historical context and rarity level
Estimated value insight
An Estimate Is Not an Appraisal
A photo may not reveal watermarks, gum, repairs, altered perforations or a convincing forgery. Do not clean, hinge or otherwise alter a potentially valuable stamp before a specialist has inspected it.

When should I ask a professional stamp expert?
Ask a reputable dealer, auction house or expertizing service when a stamp may be rare, needs authentication, is being insured or could justify a significant sale.
