In the United States, a standard book of stamps usually contains 20 postage stamps.

Quick Scoop

Most people asking “how many stamps are in a book of stamps” are talking about the regular USPS First‑Class or Forever stamp booklet you buy at the post office or grocery store. In that common format, you get 20 individual stamps in one folded booklet.

The Simple Answer

  • Standard USPS stamp book: 20 stamps.
  • They are typically Forever Stamps, so each one will always cover a standard First‑Class letter, even if prices go up later.
  • The 20‑stamp book is the format most people buy today for everyday mailing.

Are There Any Exceptions?

While 20 is the normal count, there are a few variations:

  • Some special formats or smaller panes can have 10 or 18 stamps, aimed at people who mail less often.
  • Large coils or rolls for businesses can contain hundreds of stamps, but those are not usually called a “book” in everyday conversation.

For almost all day‑to‑day situations, if you walk in and ask for a book of stamps, you will receive 20 stamps.

Bottom line: When someone asks “how many stamps are in a book of stamps,” the expected answer is 20 stamps per book in the standard USPS booklet.
