How much is a book of stamps in 2026? If you mail invoices, send holiday cards or just keep a book of stamps in a drawer for the rare paper bill, knowing the 2026 book of stamps cost helps you budget and avoid the small markups that pop up at convenience stores.

How Much Is a Book of Stamps in 2026?

A standard book of 20 USPS Forever stamps costs the current Forever rate in 2026. Each Forever stamp covers one ounce of First-Class Mail to any U.S. address and is valued at the current First-Class Forever rate (see usps.com). That rate took effect on July 13, 2025 — the first increase in about a year — and USPS confirmed in September 2025 that there would be no January 2026 rate change. The next Forever-stamp price adjustment is planned for mid-2026. For a quick price reference, see our book of stamps cost summary.

USPS sells stamps in several formats. The per-stamp cost is identical in every format — there is no volume discount on postage.

Q: Is a coil of 100 stamps cheaper than five books of 20?
A: No. A coil of 100 costs exactly the same as five books of 20. USPS does not discount postage by quantity.

Q: Do Forever stamps ever go on sale?
A: No. USPS maintains fixed pricing on all postage products. Any retailer offering stamps below face value is either running a rare loss-leader promotion or selling counterfeit product.

Recent History of Forever Stamp Price Increases

USPS has raised the First-Class Mail rate seven times since 2019 under its “Delivering for America” 10-year strategic plan, designed to move USPS to financial stability without taxpayer subsidies. The biggest single jump came in July 2024. Through these increases, a book of stamps has risen steadily from 2019 to 2026 — about 42% over seven years.

Despite the recent run of increases, U.S. First-Class postage remains among the most affordable globally — USPS published comparisons show U.S. rates below 26 of 30 comparable national postal services as of 2024.

Where to Buy a Book of Stamps at Face Value

So how much is a book of stamps at retail? Most U.S. retailers sell a book of 20 Forever stamps at face value — see usps.com for the current Forever rate. A handful of convenience and pharmacy chains mark the book up slightly. Buying directly from USPS guarantees face-value pricing.

• USPS.com — order online with free shipping to your mailbox. Guaranteed face value.
• USPS post offices — books, coils and sheets all at face value. The widest selection of stamp designs.
• Grocery stores — most major chains (Kroger, Safeway, Publix, HEB) sell Forever-stamp books at face value at the customer service counter.
• Walmart and Target — books of 20 at face value, customer service counter.
• Pharmacies (CVS, Walgreens, Rite Aid) — convenient for quick purchases, sometimes priced slightly above face value.
• Amazon — multiple authorized sellers; compare carefully because third-party listings sometimes price 10–20% above face value.

Types of USPS Stamps

• Forever stamp — the standard. Covers a one-ounce First-Class letter to any U.S. address. Never expires — valid at the current First-Class rate regardless of when it was purchased.
• Postcard stamp — for standard-size postcards only. Not valid as full letter postage.
• Additional-ounce stamp — add one per ounce when your letter exceeds one ounce.
• Global Forever stamp — covers one-ounce international letters to any country.
• Semipostal stamps — priced slightly above First-Class; surplus funds a designated cause (e.g., Breast Cancer Research, Healing PTSD).

Stamps Are Not for Packages

Forever stamps are designed for letters and flat envelopes — not packages. USPS will not accept any package over 13 oz dropped in a mailbox with only stamps affixed; over 13 oz, the package has to be presented at a post office window with proper barcoded postage. For anything in package shape, you need a prepaid shipping label, not a stack of stamps.

If you ship more than the occasional letter, prepaid shipping labels from ParcelPath give you access to USPS and UPS package rates at 60–89% below retail counter prices — no post office line and no per-letter stamp math. Print the label at home, attach it to the package, and either drop it off or schedule a free USPS pickup.

What to Watch for in Mid-2026

USPS is also implementing an 8% fuel surcharge effective April 26, 2026 on package services — not on stamps. The mid-2026 First-Class stamp adjustment has not yet been priced at the time of writing; check USPS.com for the exact effective date and new rate. Forever stamps purchased today remain valid at whatever the next First-Class rate becomes — that is the entire point of the Forever design.
