If you have a drawer full of Forever Stamps purchased at older prices, you can keep using them with confidence. The U. S. Postal Service designed Forever Stamps so that households, small businesses, and occasional mailers never have to worry about buying one- or two-cent add-on stamps after a rate increase. This guide explains the rule, shows you how to verify your stamps are still valid, and walks through practical buying scenarios so you can plan your postage spending wisely.
Current USPS letter rates
As of September 13, 2026, USPS Notice 123 lists $0.82 for an eligible stamped domestic letter up to 1 ounce, $1.11 for 2 ounces, $1.40 for 3 ounces and $1.69 for 3.5 ounces. The additional-ounce increment is $0.29, and a qualifying nonmachinable letter adds $0.49. The schedule took effect July 12, 2026.
These prices apply only after the finished piece is classified correctly. Postcards, flats, packages, international mail and added services use different rules.
What Makes a Forever Stamp “Still Good”
A Forever Stamp remains valid for mailing as long as it is an authentic, unused U. S. postage stamp issued by USPS. The key conditions are simple:
- Unused: The stamp has not been canceled, postmarked, or previously affixed to mail that went through the postal system.
- Intact: The stamp is not torn, defaced, or damaged to the point where the design or denomination is unreadable.
- Authentic: The stamp was produced by USPS or an authorized printer. Counterfeit stamps — often sold at steep online discounts — will not pass USPS verification and may result in your mail being returned or held.
There is no expiration date on a Forever Stamp. There is no time limit. You can buy a roll of 100 today, store them in a desk drawer, and use them five or ten years from now — they will still cover a 1-ounce letter.
Why Forever Stamps Were Created
Before Forever Stamps existed, every USPS rate increase meant that millions of households and businesses were stuck with stamps that no longer covered the full postage amount. If you had a book of stamps bought at $0.42 and the rate went up to $0.49, you needed to add a 2-cent stamp to every envelope. That was inconvenient, wasteful, and confusing — especially for people who only mail a few letters a year.
USPS introduced Forever Stamps in 2007 to solve this problem. The concept is straightforward: you buy the stamp at whatever the current rate is, and it remains valid for a 1-ounce letter no matter how many times rates increase after your purchase. This makes Forever Stamps one of the simplest postage tools available.
Scenarios: When Buying Forever Stamps Now Makes Sense
Not everyone needs a bulk supply of stamps. Your ideal quantity depends on how much you actually mail. Here are common scenarios to help you plan:
Household Mailers (Occasional Letters)
If you send birthday cards, thank-you notes, or a handful of bills by mail each month, a book of 20 stamps typically lasts several months. Buying a book now at $16.40 means you avoid paying $16.40 for the same quantity after July 2026.
Small Business Owners
Small businesses that send invoices, statements, or customer correspondence by mail often use 200 to 500 stamps per year. Purchasing a roll of 100 now locks in the $0.82 rate for roughly half a year’s supply. Two rolls cover a full year for many small operations.
Wedding Planners
A wedding with 150 invitations needs at least 150 stamps for the invitations alone — and many couples also need stamps for thank-you cards, save-the-dates, and response envelopes. Buying 200 to 300 Forever Stamps before a rate increase can save $8 to $12 or more on a single event’s postage.
Holiday Card Senders
Families who send 50 to 100 holiday cards each December benefit from stocking up on Forever Stamps throughout the year. Buying a book of 20 every few months spreads the cost and ensures you are never caught short during the busy season.
How to Verify Your Stamps Are Still Valid
If you already have Forever Stamps on hand and want to confirm they are still usable, check these points:
- Look for the word “Forever” on the stamp. U. S. Forever Stamps are clearly marked. If the stamp has a numeric denomination (such as “49¢” or “55¢”), it may be a traditional stamp from before the Forever program became standard — those stamps are still valid but only for their printed value.
- Confirm the stamps are unused. If there is no ink cancellation mark or postmark visible, the stamp is still available for use.
- Check the condition. Stamps that are clean, uncreased, and fully adhesive are ready to use. Stamps that have been peeled off an envelope or are partially torn may not be accepted by USPS processing equipment.
- Purchase from a trusted source. If you bought your stamps from an authorized USPS location, a licensed retailer, or a reputable online stamp seller, they are genuine. If you purchased from an unfamiliar source offering prices far below face value, inspect the stamps carefully.
What Happens If You Use an Old Forever Stamp
Nothing unusual happens — that is the point. When you affix a Forever Stamp to a standard 1-ounce letter and drop it in a mailbox, USPS treats it the same as a stamp purchased yesterday at $0.82. Your letter goes through the same sorting process and gets delivered on the same timeline. The stamp’s purchase date and purchase price are irrelevant.
The only time additional postage is needed is if your mailpiece exceeds 1 ounce, is larger than standard letter dimensions, or requires extra services. In those cases, you would add the appropriate postage regardless of which Forever Stamp you used.
Planning Your Purchase: How Many Stamps Do You Actually Need?
Before buying, estimate your annual mailing volume. Here is a simple framework:
| Mailing Type | Typical Annual Volume | Suggested Quantity |
|---|---|---|
| Personal letters and cards | 20 – 50 per year | 1 book of 20 – 3 books of 20 |
| Business correspondence | 100 – 500 per year | 1 – 5 rolls of 100 |
| Wedding (invitations + thank-yous) | 100 – 300 total | 5 – 15 books of 20 |
| Holiday cards | 30 – 100 per season | 2 – 5 books of 20 |
Buying slightly more than you think you need is usually a safe bet. Since Forever Stamps never expire, extra stamps simply carry forward to next year. There is no downside to having a small surplus on hand.
Where to Buy Forever Stamps
Forever Stamps are widely available. Common options include:
- USPS Post Offices: Direct purchase at any location. You pay face value.
- USPS.com: Online ordering with home delivery. Design selection is broad, and you can buy books, rolls, or sheets.
- Authorized Retailers: Many grocery stores, pharmacies, and office-supply stores sell Forever Stamps at face value.
- Independent Online Stamp Sellers: Some sellers offer unused, valid Forever Stamps at prices below face value. These can be a good option for buyers who want better value on larger quantities.
Regardless of where you buy, make sure the stamps are unused, genuine, and in good condition. Reputable sellers will clearly describe the stamp’s condition and source.
Frequently Asked Questions
Do Forever Stamps expire?
No. Forever Stamps do not have an expiration date. They remain valid for First-Class Mail letter postage indefinitely, regardless of when they were purchased.
Can I use a Forever Stamp from 10 years ago?
Yes. As long as the stamp is unused and in good condition, it covers a standard 1-ounce letter at whatever the current First-Class rate is — even if you bought it a decade ago.
What if my Forever Stamp has a price printed on it?
Early Forever Stamps sometimes had a denomination printed alongside the word “Forever.” The printed price does not limit the stamp’s value. It still covers a 1-ounce letter at today’s rate.
Do Forever Stamps work for packages?
Forever Stamps can be used toward package postage, but a standard 1-ounce letter Forever Stamp will not cover the full cost of a package. You would need to add additional postage to meet the package rate. For heavy or oversized items, USPS retail or online postage is usually more practical.
Are discounted Forever Stamps real?
Some legitimate sellers offer unused Forever Stamps below face value. However, extremely large discounts — such as 50% off or more — may indicate counterfeit stamps. If a deal seems too good to be true, inspect the stamps carefully before using them on important mail.
What This Means for Buyers
Buying Tips and Next Steps
Before you buy, consider:
- Estimate how many letters, cards, or mailpieces you send in a typical year.
- Match your purchase quantity to your real mailing volume — a book of 20 for occasional use, a roll of 100 for higher-volume needs.
- USPS rates effective July 12, 2026 should be treated as current, not as a future buying deadline.
- Store unused stamps in a cool, dry place to preserve adhesive quality.
- Purchase from a trusted seller to ensure the stamps are genuine and unused.
Whether you mail a few letters a year or send out hundreds of holiday cards each December, Forever Stamps let you buy once and use whenever you need — no expiration, no extra postage, no hassle.
