How Many Stamps Are In A Book Of Postage Stamps

The other day, I found myself standing in a post office line, clutching a birthday card for my niece. The woman ahead of me was buying stamps, and she asked the clerk for "a book of stamps." He handed over a small, tidy booklet, and she paid without a second glance. I, on the other hand, started obsessing over a simple, stupid question: how many stamps are in that thing anyway? I’ve bought dozens of them over the years, but I realized I’ve never actually counted. Does that make me a bad adult? Possibly.

So let’s cut to the chase, because I know you’re curious too. A standard book of stamps in the U.S.—the kind you grab at the post office or grocery store—contains exactly 20 stamps. Yes, twenty. That’s it. It’s one of those boring, consistent facts that the postal service has decided to stick with, like how a dozen donuts is always twelve. But wait, it gets weirder: you can also buy a "coil" of stamps (100 in a roll) or a "sheet" (often 20, but sometimes 10 for commemoratives). Why do they call it a "book"? Honestly, I think it’s because it looks like a tiny, stamp-bound novel.

Wait, is this a global thing? Of course not.

If you’re reading this in the U.K., Canada, or Australia, stop right here—your stamp books are different. In the U.K., a book of first-class stamps typically has 12 stamps, but they sometimes sell books of 4 or 6 for quick mail. In Canada, a booklet usually holds 10 stamps, because apparently Canadians are more efficient. And Australia? They love variety—you can get books of 10, 20, or even 50 if you’re sending a lot of love letters. So if you’re traveling, don’t assume. You’ll be that person fumbling at the counter.

But why 20? Is there a secret stamp mafia?

Honestly? No deep conspiracy—it’s just tradition and convenience. Twenty stamps is about the right number for a few weeks of bill paying and birthday cards. The U.S. Postal Service figured that most people don’t mail enough to need a hundred, but they also don’t want to buy singles every time. Side note: have you ever bought a single stamp at a machine? It feels like you’re committing a crime. The machine grumbles, and the stamp comes out looking slightly offended.

Here’s a fun twist: the price of a stamp book is simply 20 times the current stamp price. So if a stamp costs 73 cents (which it probably will by the time you read this—thanks, inflation), the book costs $14.60. That’s it. No discount, no "buy in bulk and save." You pay the same price as if you bought twenty singles, but you get a cute little booklet to lose in your car. Ironic, right?

The hidden stamp book conspiracy (just kidding, but not really)

What nobody tells you is that stamp books are designed to be mildly infuriating. Ever try to tear out a single stamp without ripping the next one? It’s a test of patience and fine motor skills. The perforations are deliberately weak in the middle, so you always end up with a jagged edge. And the glue on the back? It’s either too sticky (fingers stuck together) or not sticky enough (stamp floats off your envelope in the rain). You know what I’m talking about.

Then there’s the retired stamp book—the one you find in an old purse or a junk drawer. It has 14 stamps left, but they’re all outdated. Can you still use them? Yes, technically. But you’ll feel like a rebel doing it. I have a book from 2018 with a picture of a dinosaur on it, and I still use those stamps for bills. The postal workers don’t care. They just scan and move on. Free the dinosaur stamps!

What about the "forever stamp" factor?

Ah, the forever stamp—the genius scam that makes you feel smart. If you buy a book of forever stamps today, they’re good even if prices go up tomorrow. So a book of 20 forever stamps is basically a time-traveling investment. But here’s the catch: forever stamps never come in books of 20 if you buy them online. The website often sells them in rolls of 100 or sheets of 10. Why? Because the postal service wants you to overthink it. I swear they do it on purpose.

So next time you’re at the counter, you can confidently answer the question "How many stamps in a book?" with "20, unless I’m in Canada." And then you can laugh at yourself for caring this much. I’m laughing with you, I promise. If you ever find a book with 19 stamps, just know that you’ve been cheated, or that a stamp escaped into the wild. Both outcomes are equally likely in 2025.

Final thought: The real number of stamps in a book might as well be a metaphor for life—always 20, but never enough for all the people you should have written to. So go buy a book, send a card, and stop worrying about the count. Unless you’re in Canada. Then buy two books.
