Can You Use Old Forever Stamps?

Yes. Old Forever stamps are still valid, and they are worth more today than when you bought them. A Forever stamp always pays the current price of a 1-ounce First-Class Mail letter — $0.82 under the price list in effect since July 12, 2026 — regardless of whether you bought it last month for $0.78 or in 2007 for $0.41. There is no expiration date and nothing to exchange. This article, part of our Postage & Stamp Guides center, covers the rules, the exceptions, and how older non-Forever stamps work alongside them.

Why Old Forever Stamps Keep Working

The entire point of the Forever stamp, introduced in 2007, is that its value is not printed on it. Instead of being worth a fixed number of cents, it represents one unit of a service: mailing a standard 1-ounce letter. When USPS raises the letter price — most recently from $0.78 to $0.82 on July 12, 2026 — every unused Forever stamp in every kitchen drawer in America quietly becomes worth the new price.

That means the book of Forever stamps you bought two price increases ago is not a loss or a collector’s problem. It is fully current postage, and in fact it appreciated: you paid the old price for what is now $0.82 of mailing value per stamp. For background on how the system works, see What Is a Forever Stamp? A Complete Guide.

The Conditions: Unused, Undamaged, Recognizable

“Forever” has limits, and they are about the physical stamp, not its age. An old stamp can be refused if:

• It has already been used. A stamp that has gone through the mail and been cancelled cannot be used again, even if the cancellation mark is faint.
• It is torn, cut, or heavily damaged. The Postal Service needs to be able to recognize the stamp as genuine postage.
• It is taped over or coated. Covering a stamp with clear tape can interfere with how USPS processing equipment reads it, and it may be rejected.
• It is a photocopy, scan, or printout. Reproductions are not postage at all, no matter how crisp they look.

Ordinary aging is fine. A stamp that has yellowed slightly in a drawer, or an older design you no longer see for sale, is still good as long as it is unused and intact.

What About Old Stamps With a Printed Value?

Denominated stamps — the ones with a cent amount printed on them — also never expire, but they behave the opposite way: they are worth exactly their printed value, forever. A 29-cent stamp from the 1990s still contributes 29 cents of postage today. It just does not grow.

You can combine stamps freely on one envelope. The total of the face values simply has to meet or exceed the postage due. For example, a 2-ounce letter costs $1.11 today; you could pay it with:

• One Forever stamp ($0.82) + one 29-cent stamp = $1.11
• One older $0.58 stamp + one $0.53-era combination of smaller stamps totaling at least $1.11
• Any handful of small denominations that adds up to $1.11 or more

Overpaying slightly with old stamps is harmless; underpaying is what gets a letter returned or delivered postage-due. Our weight-by-weight table in How Many Stamps Do I Need for a Letter? shows the exact totals to aim for.

Worked Examples: Paying Real Postage From a Mixed Drawer

Say a drawer cleanout turns up the following: two Forever stamps from a few years ago, a 58-cent stamp, a 53-cent stamp, several 29-cent stamps from the 1990s, and a handful of 2- and 3-cent make-up stamps. Here is what that drawer can mail at today’s prices:

• A square 1-ounce greeting card ($1.31). One Forever stamp ($0.82) plus the 29-cent stamp plus two 3-cent stamps and… that totals $1.17 — not enough, and fussy besides. Cleaner: the 58-cent + 53-cent + 29-cent stamps = $1.40. It overpays by nine cents and clears the drawer of odd values in one envelope.
• A 3-ounce document envelope ($1.40). The 58-cent and 53-cent stamps plus one 29-cent stamp add up to exactly $1.40. Exact-change combinations like this are where old denominated stamps quietly earn their keep.
• Two ordinary letters ($0.82 each). The two old Forever stamps, one per letter — each is worth today’s full letter price no matter what was paid for it.

Two rules of thumb emerge from the math. Spend denominated stamps on the mailings with awkward totals (surcharges and heavier weights), where their odd values can be combined precisely. Save Forever stamps for plain 1-ounce letters, where each one is exact by definition. And when a combination falls a few cents short, one of the small make-up stamps — the reason they were printed — closes the gap; postage that meets or slightly exceeds the amount due is always acceptable.

Sorting a Stamp Drawer in Decatur, Step by Step

The mixed drawer in the examples above is not hypothetical — it is what turns up in a desk drawer in Decatur when a parent’s house is being settled, or in a Midtown apartment when a grandparent’s desk changes hands. Old stamps are a genuinely Atlanta inheritance. Here is the sort we recommend, in order, with a running tally:

1. Empty the drawer onto the table and make three piles. Pile one: anything printed with the word “FOREVER” — today each of those is worth $0.82. Pile two: stamps with a printed cent value — worth exactly that value. Pile three: anything round and marked “GLOBAL FOREVER” — worth $1.75 toward international mail. In a typical inherited drawer that might be 6 Forever stamps ($4.92 of postage), a 58-cent and a 53-cent stamp, some 29-cent stamps, and small make-up values.
2. Pull out anything already used. Look for cancellation marks, however faint, and for stamps still glued to clipped envelope corners. Those are spent — set them aside for a keepsake envelope, not the postage pile.
3. Check condition, not age. Yellowing is harmless. Tears, tape, water damage, and heavy creasing are the disqualifiers. Anything questionable can go in a “counter check” envelope: a Post Office clerk will tell you in seconds whether it is usable, free of charge.
4. Spend the piles in the right order. Denominated stamps first, on the awkward totals — the $1.31 square card, the $1.40 three-ounce letter — where odd values combine precisely. Forever stamps last, on plain 1-ounce letters, where each is exact by definition.

One Atlanta-specific caution about adding to the drawer: stamps offered at steep discounts — half of face value is the classic pitch — through unfamiliar online sellers are very often counterfeit, and a counterfeit bought last year is not “old postage,” it is no postage at all. The inherited drawer is trustworthy because you know where it came from; a too-cheap listing deserves the suspicion described in the caution below.

One Caution: Where the Old Stamps Came From

Stamps found in your own drawer are fine. Stamps bought recently from unfamiliar online sellers at implausibly deep discounts deserve skepticism: counterfeit Forever stamps are a documented problem, and counterfeits are not valid postage no matter how convincing they appear. If a deal prices Forever stamps far below their face value from a seller you have never heard of, the risk is that you are buying decorations, not postage. Buying through established channels — listed in our Stamp Buying Guide — avoids the question entirely.

Common Mistakes With Old Stamps

• Reusing a stamp that “looks unused.” If an envelope went through the mail, its stamp is spent — even when the cancellation mark missed it or is barely visible. Peeling and re-gluing a delivered stamp is not a gray area; it is reusing postage, and the letter can be returned or assessed.
• Cutting stamps off old envelopes to use them. Same problem from the other direction: a stamp still attached to a clipped corner of a mailed envelope has already done its job.
• Taping a loose stamp down. Tape over the stamp’s face can make it unreadable to processing equipment. A stamp whose own adhesive has failed is safer carried to a Post Office counter for advice than taped at home.
• Assuming foreign stamps count. Only U.S. postage pays for mail posted in the United States. Attractive stamps from other countries are worth zero on a domestic envelope.
• Throwing away small denominations. The 2-, 3-, and 5-cent stamps in a drawer are precisely what turns a 73-cent combination into the 82 cents a letter needs. Small stamps are the change that makes the rest of the drawer spendable.

The Bottom Line

Use your old Forever stamps with confidence — each one mails a 1-ounce letter at today’s $0.82 rate. Use old denominated stamps too, at their printed face value, combining as many as you need. Just make sure every stamp on the envelope is genuine, unused, and undamaged, and your drawer full of forgotten postage is money you have already spent wisely.

Frequently Asked Questions

Do Forever stamps expire?

No. There is no expiration date.

Is a Forever stamp bought at $0.55 still enough for a letter?

Yes — it is worth the current $0.82 letter price.

Can I use stamps from another decade?

Yes, if they are unused, intact U.S. postage. Their printed values still count at face value.

Can I mix old and new stamps on one envelope?

Yes. Add up the values; meet or beat the postage due.

Do old stamps cover extra ounces?

They contribute their value toward the total, including the 29-cent-per-additional-ounce charges on heavier letters.

Can I use old stamps on a letter to another country?

Yes — their values count toward the total postage just as they do domestically. A 1-ounce international letter needs $1.75, so combinations of older stamps work as long as they reach that amount; one Global Forever stamp is simply the tidier option.

Are commemorative and collectible-looking stamps still valid?

If they are genuine, unused U.S. postage, yes — a decades-old commemorative used at face value is worth its printed amount. Whether mailing it is wise is a different question: a stamp with real collector value is worth more kept than spent. Ordinary drawer stamps, though, have no premium — use them.
