Do Forever Stamps Expire? What Forever Actually Means

The word "Forever" is stamped right on the stamp. But what does it actually mean? Will a Forever stamp you bought in 2018 still mail a letter in 2026? What about 2036?

No, Forever stamps do not expire. They remain valid for postage forever—hence the name. But the details of how their value works over time are worth understanding.

What "Forever" Means in Practice

A Forever stamp is a type of nondenominated stamp. Unlike older stamps that had a specific cent value printed on them (such as "37 cents"), a Forever stamp has no printed denomination. Instead, its value is tied to the current First-Class Mail one-ounce letter rate.

This means:

• A Forever stamp bought in 2018 for $0.50 is worth $0.82 in 2026
• A Forever stamp bought in 2026 for $0.82 will be worth whatever the rate is in 2030
• The stamp's value is always the current rate on the day you use it, not the rate on the day you bought it

5 Myths About Forever Stamp Expiration

Myth 1: "Stamps have an expiration date printed on them."

False. Unlike food, medication, or coupons, postage stamps have no expiration date. USPS has never issued stamps that expire. The "Forever" designation is a guarantee, not a countdown.

Myth 2: "Old Forever stamps are worth less than new ones."

False. All unused Forever stamps, regardless of when they were issued, are worth the current one-ounce letter rate. A Forever stamp from 2007 (the first year they were issued) has the same postage value as one printed yesterday.

Myth 3: "If the rate decreases, your stamps lose value."

Partially true, but irrelevant in practice. Postage rates have never decreased in the history of the Forever stamp program (since 2007). While a rate decrease is theoretically possible, it has never occurred, and there is no indication it will occur in the foreseeable future.

Myth 4: "Stamps become invalid if they were bought from a discount seller."

False. The validity of a stamp is determined by its authenticity, not by where or for how much it was purchased. An authentic Forever stamp is valid regardless of whether you paid $0.82 at the post office or $0.25 from a discount seller.

Myth 5: "If the design changes, old designs stop working."

False. USPS issues new stamp designs regularly, but old designs remain valid. You can still mail a letter with a 2015 flag stamp, a 2018 flower stamp, or a 2022 holiday stamp. The design does not affect validity.

Historical Forever Stamp Values

What CAN Make a Stamp Unusable

While stamps do not expire, they can become physically unusable:

• Damage: Torn, heavily creased, or water-damaged stamps may be rejected
• Missing adhesive: Self-adhesive stamps that have lost their stickiness may not stay on the envelope
• Already used: Stamps with cancellation marks have already served their purpose and cannot be reused
• Counterfeit: Fake stamps have no postage value and will be rejected

The conditions above are physical problems, not expiration. A well-stored Forever stamp in good condition is valid indefinitely.

Frequently Asked Questions

Can I still use stamps I bought 10 years ago?

Yes. If they are unused and in good physical condition, they are still valid. Forever stamps will be worth the current rate. Older denominated stamps (with a specific cent value printed) are worth exactly that cent value.

Do international Forever stamps also not expire?

Correct. Global Forever stamps work the same way: they are always worth the current one-ounce international letter rate, regardless of purchase date.

What if a stamp was issued before 2007?

Pre-2007 stamps are not Forever stamps—they have a specific denomination printed on them. A stamp marked "37 cents" is worth 37 cents of postage, no more. You can combine multiple older stamps to meet the current rate.

Postage rates are current as of July 12, 2026.
