Forever Stamps: The Complete Guide to Postage That Never Loses Value

If you’ve ever wondered whether those Forever stamps in your drawer are still good after a postage rate increase — the short answer is yes, always. In this guide, we’ll explain what Forever stamps are, why they’re one of the smartest small purchases you can make, and how to use them to lock in today’s rates for years to come.

What Is a Forever Stamp?

A Forever stamp is a First-Class Mail stamp issued by the United States Postal Service with a special guarantee: it will always cover the cost of mailing a one-ounce letter, no matter when you bought it or how much rates rise in the future. The word “FOREVER” is printed on every one, right beside the design.

Forever stamps were introduced in 2007, and they’ve been a favorite of savvy mailers ever since. Buy them at today’s price, use them in 2036 — the postage value rides along automatically with every rate change.

Why Forever Stamps Are a Smart Buy

• Rate-increase insurance. USPS raises First-Class rates almost every year. A Forever stamp bought today keeps working after every future hike — your cost per letter is locked in.
• No expiration, ever. Unlike coupons or promotional credits, Forever stamps never expire. Tuck a roll in a drawer and forget about it for a decade.
• Perfect for budgeting. Small businesses that mail invoices, invitations, or greetings regularly can buy in bulk when cash flow allows and use them anytime.
• Collectible designs. From the American Flag series to wedding florals, holiday art, and beloved pets — Forever stamps double as miniature pieces of American art.

How Rate Increases Work (And How Forever Stamps Beat Them)

When USPS announces a rate increase, stamps showing the old price don’t become invalid — but if you buy them after the increase, you pay the new, higher price. Forever stamps remove that problem entirely: the stamp you hold is always worth exactly “one ounce of First-Class postage,” whatever that costs on the day you mail it.

In other words, buying Forever stamps before a rate increase is like buying postage at a permanent discount. That’s exactly what we help you do at US Stamps Deals — genuine Forever stamps at below-Post-Office prices, every day.

Using Forever Stamps: The Basics

• Domestic letters: one Forever stamp covers a standard one-ounce letter anywhere in the United States.
• Heavier mail: add extra postage (additional-ounce stamps or a second Forever stamp) for each extra ounce.
• International mail: Forever stamps can be combined to meet international rates — three currently cover a one-ounce international letter.
• Mixed designs: you can combine different Forever stamp designs on the same envelope. Mixing a Flag stamp with a Floral stamp is perfectly fine.

Tips for Storing Your Stamps

To keep unused stamps in perfect condition: store them flat, away from direct sunlight and humidity, ideally in their original packaging. Properly stored stamps retain both their postage value and their collectible appeal for decades.
