How do I identify an antique stamp?

Upload a clear scan of the stamp showing all design details. Our AI analyzes design, color, perforations, and any overprints to match the stamp against major philatelic catalogs.

Can you identify stamps from any country?

Yes — we cover stamps from all issuing countries worldwide from the first stamps of 1840 to mid-20th century issues, including all major colonial issues, back-of-book stamps, and precursor stamped envelopes.

How do I know if my old stamp is valuable?

Rarity, condition, centering, and gum condition all affect value. Our identifier flags stamps likely to have significant philatelic value and provides approximate catalog number and value range.

Can you identify stamp watermarks?

Watermark identification typically requires holding the stamp to transmitted light or using watermark fluid. If you can photograph your stamp against a light source, our AI can often identify watermark type.
