Forever Stamps do not expire. A genuine, unused regular Forever Stamp continues to cover the current one-ounce domestic First-Class Mail letter price, even if its artwork or purchase date is years old.
The important words are genuine and unused. “Forever” protects the stamp’s postal value from future price increases; it does not make a damaged stamp reusable or guarantee that every old-looking item offered online is authentic.
Why old Forever Stamps remain valid
USPS describes a Forever stamp as nondenominated postage whose value always equals the prevailing one-ounce First-Class Mail letter price. The first U.S. Forever Stamp was issued in 2007. A stamp bought at an earlier price therefore rises with that one-ounce rate instead of needing a small make-up stamp after every price change.
As of August 11, 2026, one regular Forever Stamp represents $0.82. If you bought it when the price was lower, you do not pay the difference for an eligible one-ounce letter.
Old artwork is not the same as expired postage
This is where buyers most often hesitate. A holiday design from a past year, an older flag, or a discontinued commemorative issue may look “out of date,” but the design year does not cancel the Forever value.
The review data shows the practical side of that confusion. Product mismatch appeared in 859 of the 12,101 reviews analyzed. Some low ratings came from receiving an older design than expected, while other buyers explicitly valued older unused stamps. Those reviews can show disappointment with a listing, but they cannot decide postal validity. USPS rules do.
When an old stamp may not be usable
- It has already been canceled. Postmarks or cancellation bars generally mean the postage has been used.
- It is torn or materially damaged. If key parts are missing or the stamp cannot be recognized, ask USPS before mailing.
- The adhesive has failed. Do not cover a stamp with tape. Ask a Post Office how to handle an older stamp that will not stay attached.
- It is counterfeit. A fake item never acquires postal value because time has passed.
- It is not a regular one-ounce Forever denomination. Postcard Forever, Additional Ounce, two-ounce, and Global Forever stamps follow their own categories.
Do I need extra postage on an old Forever Stamp?
Not because the stamp is old. You may need extra postage because the mailpiece is heavier, square, rigid, unusually thick, a large envelope, or international.
| Example | What the old regular Forever Stamp contributes | What to check |
|---|---|---|
| Eligible domestic letter up to 1 oz | The full current $0.82 rate | No extra postage based only on age |
| Eligible domestic letter over 1 oz through 2 oz | $0.82 | Add $0.29 |
| Square or rigid letter | $0.82 | Applicable letter price plus $0.49 surcharge |
| Eligible 1 oz international letter | $0.82 | Total required is $1.75 |
How to store older stamps
Keep unused stamps flat, dry, and away from heat and direct sunlight. Leave self-adhesive stamps on their original backing until needed. If you are keeping an issue as a collectible rather than postage, use archival materials and avoid touching the stamp surface more than necessary.
Before using stamps found in a drawer
- Confirm the stamp says FOREVER or identify its specific denomination.
- Look for cancellation marks or obvious damage.
- Make sure the physical stamp—not just an online listing—appears consistent with the issue.
- Classify and weigh the finished mailpiece.
- When authenticity or condition is uncertain, take it to USPS rather than relying on a home test.
