You are holding a small rectangle of paper with a portrait on it, a number, and words in an alphabet you may not read. Before anyone can tell you what it is worth, somebody has to answer a narrower question first: what is this stamp? Learning how to identify a stamp is mostly a matter of doing the checks in the right order, because the order is what saves you from an afternoon of dead ends.
Identify a stamp in this sequence: country first, then the script and currency clues that confirm it, then the year and denomination, then the design or series it belongs to, then the catalogue number, and only then the fine varieties such as watermark and perforation. Country comes first because every stamp catalogue in the world is organised by country before anything else.
Most guides start at the wrong end, opening with perforation gauges and watermark trays. That is not where beginners actually get stuck. People get stuck on the first step, staring at a word like HELVETIA or a line of Cyrillic and having nowhere to look it up. So the useful question is not which gauge your stamp measures, it is which of the several hundred countries, colonies, and occupation authorities that have issued stamps printed this one.
Why does country identification come first?
Because it is the key to every reference you will use. The major catalogues, Scott, Stanley Gibbons, Michel, and Yvert et Tellier, all sort the world’s stamps by country of issue and then by date and issue within each country. A catalogue number on its own is meaningless without the country attached to it, since each publisher restarts its numbering for every country it lists.
That is why the American Philatelic Society opens its identification guidance the same way: work out the country, then use a catalogue to find the issue date and the value. Everything else, including the checks that feel more technical and therefore more serious, depends on having the country right.
How to identify a stamp when the country name is not in English
This is the step where most people stall, and it is easier than it looks. The Universal Postal Convention requires that a modern postage stamp carry the name of the issuing country in roman letters, or, on formal request to the UPU’s International Bureau, the official abbreviation or initials standing in for it. Roman letters are not the same thing as English, though: the name on the stamp is the country’s name for itself.
A short list covers a surprising share of what turns up in an inherited album:
- HELVETIA is Switzerland, the Latin name the country uses to avoid choosing between its four national languages. Latin does the same diplomatic job elsewhere: HELLAS is Greece and SHQIPERIA is Albania under its own name for itself.
- The country’s own name for itself, which is the usual case: MAGYAR or MAGYAR POSTA is Hungary, SVERIGE is Sweden, NORGE is Norway, DANMARK is Denmark, SUOMI is Finland, ISLAND is Iceland, ESPAÑA is Spain, ÖSTERREICH is Austria, BELGIË or BELGIQUE is Belgium, POLSKA is Poland, ČESKOSLOVENSKO is the former Czechoslovakia, NIPPON is Japan.
- Names that changed with the politics, which is where dates hide: DEUTSCHES REICH is Germany before 1945, DDR is East Germany, BUNDESPOST is West Germany, CCCP in Cyrillic is the Soviet Union, PERSANES or POSTES PERSANES is Iran before 1935.
- Colonial and successor names, which send people to the wrong catalogue section: NEDERLAND is the Netherlands while NEDERLANDSCH-INDIË is the former Dutch East Indies, now Indonesia; CEYLON is Sri Lanka; RHODESIA is Zimbabwe or Zambia depending on the year; SIAM is Thailand before 1939.
Older material may carry no roman lettering at all, because the roman-letters rule is a modern convention and classic issues predate it. Then the script itself is the clue. Cyrillic points to Russia, the Soviet Union, Bulgaria, Serbia, or their neighbours. Arabic script points to the Middle East and North Africa. Chinese, Japanese, and Korean characters place a stamp in East Asia, and Greek, Hebrew, Thai, and Devanagari each narrow the field immediately.
Currency is the strongest second clue, and it often settles what the script only suggests, though every one of these is a narrowing clue rather than a verdict. Kopecks point to Russia, the Soviet Union, or one of the post-Soviet states that kept the unit. Pfennigs point to Germany. Öre points to Scandinavia. Annas mean British India or its neighbours before decimalisation. Centavos mean Latin America, Portugal, or the Philippines. A magnifier helps, because the country name is frequently set in tiny type along the bottom margin rather than across the design.
What if the stamp has no country name at all?
There is one famous exception, and it is written into international postal law. Article 6 of the Universal Postal Convention sets out what a postage stamp comprises, beginning with the name of the issuing member country in roman letters and the face value. A footnote to that article grants an exception to the United Kingdom of Great Britain and Northern Ireland, described there as the country which invented the postage stamp.
That exemption is why British stamps identify themselves with the reigning monarch’s profile instead of a country name. If you are holding an ordinary postage stamp with a monarch’s head, a denomination, and no country anywhere on it, the odds are strongly that it is British. Revenue stamps, local posts and the various labels that turn up loose in albums do not follow the Convention at all, so treat this as a strong first guess rather than a proof.
Note the limit of the rule: British colonies and Commonwealth countries were never covered by it, so a stamp reading BERMUDA or CEYLON under a portrait of the same monarch is a colonial issue and belongs in a different catalogue section entirely.
Two other no-name cases catch people out. Local posts and private carriers sometimes printed no country. And a great many small paper labels that look like stamps are revenue stamps, poster stamps, or advertising labels that were never valid for postage at all.
How do you pin down the year and denomination?
Once you have a country, the denomination and the design narrow the date fast. Currency reforms are the sharpest tool available: a British stamp priced in pence written as a lowercase d is pre-decimal, since the United Kingdom switched to decimal currency in 1971, and any stamp denominated in a currency that no longer exists dates itself to the era before that changeover.
Portraits do the same work. In Britain, the monarch on the stamp brackets the issue inside a single reign. Elsewhere, a head of state, an anniversary date printed in the design, or a commemorative subject often names its own year. Many modern stamps simply print the year of issue in a corner, which is worth checking before you do anything cleverer.
Where does the catalogue number come in?
Near the end, because the catalogue number is the output of identification rather than the input. Once you know country, approximate date, denomination, and design, you can find the matching listing and read off its number.
Remember that the same stamp carries a different number in each catalogue, so a number means nothing unless you say which system it comes from. If you contact a dealer or list a stamp for sale, name the catalogue alongside the number. Which catalogue number you land on is also what decides the money, for the reasons we set out in what makes a stamp valuable.
Why do watermark and perforation checks come last?
Because they are tie-breakers, not finders. A perforation gauge measures how many perforation holes fall within a two-centimetre span along the stamp’s edge, which is why you see descriptions such as perf 11 or perf 12. A watermark is a faint pattern pressed into the paper during manufacture. Both are genuinely decisive when a catalogue splits one design into several listings on exactly that basis, and both are useless before you get there.
Run a gauge over an unidentified stamp and you learn a number with nothing to compare it to. Reach the right catalogue entry first, see that it says this design exists with two different perforations or two different watermarks, and the same measurement suddenly decides which row you are in. That is the moment to check the paper, using the kitchen-table method in how to see a stamp watermark in 60 seconds.
What identification usually tells you
Honestly, it usually tells you that you own a common stamp. Billions of stamps were printed, most survive in quantity, and the ordinary result of a careful identification is a catalogue number worth cents rather than a discovery. Condition and cancellation then adjust that figure further, which is the subject of whether used stamps are worth anything.
That is still the right work to do, because identification is the step every other answer hangs on. You cannot price, sell, insure, or sensibly store a stamp you cannot name. If you would rather not work through the sequence by hand, photograph the stamp with a stamp identifier app and Stampo reads the country, date, and denomination for you, then tells you honestly when a watermark or perforation check is the only thing left standing between you and a confident answer.
