Current Price and What You Get
A book of 1st class stamps in the United States currently sells for $6.80 and includes 20 stamps, each covering the one-ounce First-Class Mail letter rate. This per-book price equates to $0.34 per stamp and has been stable since January 2023, following a decrease from $6.95 in late 2022. First-class stamps remain valid forever as long as they bear the correct current denomination value, so older stamps can be combined with additional postage to meet current rates.
Typical Book Contents and Rate Details
Each book contains 20 identical stamps with a total face value of $6.80 when priced at $0.34 apiece. The First-Class Mail one-ounce letter rate is the relevant benchmark for domestic 1 oz envelopes; heavier letters require additional ounces at set step rates. Buying a book is usually the most cost-effective way to purchase multiple first-class stamps, and unused stamps retain value indefinitely if postal rates increase.
Recent Pricing Changes and Context
In late 2022 the price of a book decreased slightly from $6.95 to $6.80, while the single stamp price dropped from $0.58 to $0.55. These adjustments reflected ongoing postal pricing strategies and legislation influencing rate-setting. Since January 2023 there has been no further change to the book price, providing a stable reference point for consumers and businesses that plan mail volumes.

Where and How to Buy
You can purchase 1st class stamp books at United States Post Offices, many grocery and big-box stores, pharmacies, and online via USPS.com. Buying online or at a post office guarantees new, uncancelled stamps; retail locations often mix new and previously cancelled stock. If you need only a few stamps, single stamps or smaller coils may be available, but books typically offer the lowest per-stamp cost and are useful for weddings, holiday mailings, and small businesses that mail frequently.
International and Additional Considerations
Prices and formats differ for international mail, postcard rates, and nonmachinable items. First-class international letters require additional postage above the domestic rate, and specific countries have their own pricing. For heavy parcels or packages, First-Class Package Service or other parcel options are appropriate rather than stamp books. Understanding these distinctions helps avoid underpayment and ensures timely delivery.
Value and Long-Term Use
Because Forever Stamps on books remain valid at whatever the current first-class letter rate is, they serve as a hedge against future rate increases. Buying books when rates are lower and using them over time can simplify future mailing costs. Keep unused stamps in a safe, dry place; there is no expiration or mandatory retirement date as long as the stamp remains serviceable and you add any required additional postage for heavier weights.
