Every postage stamp carries the same three pieces of information, and once you know to look for them you can place almost any stamp from anywhere without reference material.
One of the three is missing from an entire country's output, and that absence is the most useful identification shortcut in philately.
1. The issuing authority
Somewhere on the face, a stamp says who issued it — a country name, an abbreviation, or a distinctive mark. "United States Postal Service" or simply "USA" on American issues.
This is the primary identifier, and it can change over time within the same country as postal administrations are renamed, which is itself datable evidence.
The exception
British stamps carry no country name. They show the monarch's head in silhouette and nothing else identifying the nation.
The reason is precedence: Britain issued the world's first adhesive postage stamp, and at the time there was nothing to distinguish it from. By the time other countries began printing their own — and putting their names on them — the British convention was established, and it was never changed.
So a stamp with a royal silhouette and no country name is British. That is the whole rule, and it works every time.
2. The denomination
The value, in the issuing country's currency, normally set to a common mail rate.
Several categories break the pattern, and they are worth recognising:
- Nondenominated — no printed value at all. Forever stamps are the familiar case: the value is defined by the rate at the time of use rather than by anything on the stamp.
- Dual-currency — two currencies shown, issued during transitions or in territories using more than one.
- Semi-postal — a postage value plus a surcharge that goes to a designated cause. You pay more than the postage and the difference is a donation.
- Surcharged — the original value overprinted with a new one. Postal authorities can revalue existing stock rather than reprint it, and the overprint is the record of that decision.
What a stamp sells for is a separate question
A correction here, because badly translated guides state the opposite. It is often claimed that nobody may sell a stamp above or below its face value.
That is not the rule in the United States. Post offices sell at face and do not discount. But once a stamp has been sold, it is ordinary property: resale above face is routine for anything scarce, and resale below face is a normal, legal market for surplus and retired stock. Souvenir sheets and certain special issues are even sold by the postal service itself above their postage value, because you are buying the object rather than only the postage.
Face value tells you what a stamp will pay for. It does not tell you what it costs.
3. The design
Everything printed on the face — the main image, the frame and borders, plus the country marking, the denomination, any text stating the purpose of the issue, and often a year of issue.
Subject is what most collections are organised around, and it is the element with the most deliberate thought behind it: a stamp is a small piece of national self-presentation, printed in millions.
A distinction worth keeping straight
Postage-paid designs printed directly onto envelopes, postcards and wrappers are not stamps. They are postal indicia — the same function, a different object — and in philatelic terms they belong to postal stationery rather than to stamps. Calling them stamps will confuse anyone you are talking to.
The categories you will actually meet
- Definitives — the everyday workhorses, printed in vast quantities, in print for years, suitable for any mail. Also the material for the most serious plate studies, precisely because there is so much of it.
- Commemoratives — issued for an anniversary, an event or a person, printed once, withdrawn after roughly a year.
- Special issues — a loose category covering stamps with a particular function or a defined theme outside the two above. The term means different things in different countries, which is worth remembering when reading foreign catalogues.
- Airmail — issued for airmail specifically, and almost universally designed around aircraft.
- Postage due — not bought by senders at all. These are applied by the post office to collect underpaid postage from the recipient, which makes them the one category you never want to see.
Beyond those: official stamps for government mail, military mail, parcel post, registered mail, express, and newspaper stamps. Most are historical, and their existence is a reminder of how finely mail used to be subdivided before automation made a single rate ladder simpler than a dozen specialised ones.
Two modern formats
Personalised stamps pair a fixed postal design with an adjacent label carrying customer-supplied content — a photograph, an event, an advertisement — within whatever a postal administration permits. The US ran such a programme and has since closed it.
Automated or electronic stamps are printed on demand by a machine at the point of sale, in the exact denomination requested, onto a blank pre-printed pattern. Not collectible in the usual sense, and the reason a vending machine can sell you any value you like.
One dating correction
You will see it said that postage stamps first appeared in the middle of the seventeenth century. They did not. The 1600s produced prepaid postal marks — handstamps applied by a post office to show payment — which is a real ancestor but not the same object. The adhesive stamp you stick on an envelope is a nineteenth-century invention.
Best deals on Forever stamps
Nondenominated postage is the one category where what you paid and what you get are permanently separate. That gap is the entire reason surplus Forever stamps can sell below face and still be worth full postage to the buyer.

The short version
Issuer, value, design. No country name plus a royal silhouette means Britain. Nondenominated means the rate at time of use, not zero. Postage-paid printing on an envelope is not a stamp. And face value is what a stamp pays, not what it costs.
