How to identify a stamp: a beginner's guide
Published: 18 July 2026
Every postage stamp carries a handful of clues that tell you what it is, where it came from and roughly when it was printed. Philatelists read these clues in seconds — and with a little practice (or one photo in StampSnap), so can you.
1. Start with the country
Most stamps name their country in Latin script, but the name may not match the modern one. Look out for "Magyar" (Hungary), "Helvetia" (Switzerland), "Suomi" (Finland), "Deutsches Reich" / "DDR" (historical Germany), "CCCP" (Soviet Union) and "España" (Spain). One famous exception: Great Britain never prints its name — as the inventor of the postage stamp it identifies itself only by the monarch's head.
2. Read the denomination
The face value and its currency narrow down both country and era. "1d" is a pre-decimal British penny (before 1971); "kr" could be Scandinavian; centavos, kopeks, pfennig, annas and paise each point somewhere specific. A currency that no longer exists is a strong hint the stamp is old.
3. Look at the portrait or subject
Rulers date stamps very precisely: a young Queen Victoria means 1840–1860s, King George V means 1910–1936, and so on. Commemorative subjects (events, anniversaries, Olympics) often print the year right on the stamp.
4. Check the perforations
The toothed edges are more informative than they look. Early classics like the Penny Black (1840) were imperforate — cut apart with scissors, so straight edges are correct, not damage. Later issues have measurable perforation gauges that catalogues use to tell near-identical printings apart.
5. Find the watermark
Many older stamps carry a watermark — a design pressed into the paper, visible when held against light or laid face-down on a dark surface. Two stamps that look identical from the front can be different (and differently valued) issues because of the watermark alone.
6. Study the postmark
A cancellation can date a used stamp to the day and place it in a town. Clear, well-struck postmarks on old covers are sometimes worth more than the stamp itself.
The fast way: identify a stamp by photo
Working through catalogues takes hours per stamp. StampSnap does the identification from a single photo: point your phone at the stamp and the app tells you the country, year, series and category — and estimates what collectors might pay. It's free to try, and it's the quickest first pass over a big inherited album.
