Do Forever Stamps Expire?

Short answer: no. Forever stamps don't expire. Not after five years, not after twenty. If you're staring at a strip of flag stamps that's been riding around in a kitchen drawer since 2012 and wondering, "do Forever stamps expire, or did I just waste money by forgetting about these?" — relax. Are Forever stamps still good? Every single one of them, from the very first sheet printed in 2007 to whatever's at the post office counter today.

We can say that with some confidence because we handle old stamps for a living. Our shop buys surplus unused postage in bulk — mostly from businesses that closed and left file cabinets full of stamps behind — and a big share of what crosses our inspection table is eight, ten, fifteen years old. If age made stamps worthless, we wouldn't have a business.

Why Forever Stamps Never Expire

A Forever stamp isn't worth a fixed dollar amount. That's the whole trick. When the Postal Service introduced them in 2007, the idea was simple: whatever you paid for the stamp, it will always cover one ounce of First-Class Mail. No cents printed on the face, no fine print, no expiration date — because there isn't one.

When postage rates go up (and they do, regularly), the mailing value of every Forever stamp you already own rises to match. The stamp your uncle bought during the Obama administration covers exactly the same letter as one bought this morning. We're deliberately not quoting the current rate here — it changes often enough that any number we print would go stale. The point is that your stamp always equals it, automatically.

One quiet consequence people miss: old Forever stamps are actually worth more mailing value now than their original buyer paid. A closed office that stocked up years ago effectively pre-paid for postage at yesterday's rates. That's part of why surplus stamps exist as a market at all, and why our Forever stamps collection is largely built from exactly that kind of stock.

Can You Use Old Forever Stamps? Condition Matters, Age Doesn't

So yes, you can use old Forever stamps. The only thing that can retire a stamp is physical damage, and even that has to be fairly serious.

Here's what we actually look for when a lot of older stamps comes in:

• The adhesive. Forever stamps are self-adhesive, and the gum is the first thing to fail if stamps were stored badly. Heat is the enemy — a booklet left in a car glovebox through two summers will fuse to its backing paper. If the stamp peels off cleanly, it's fine.
• The face. Tears, heavy creases, or water stains that obscure the design can get a stamp rejected at the counter. Light shelf wear won't.
• Whether it's genuinely unused. A cancellation mark, even a faint one, means the stamp has done its job already.

Out of a typical estate or office lot, we reject maybe one strip in twenty — and it's almost always heat damage or moisture, never age itself. Stamps kept flat, dry, and out of direct sun hold up for decades. Some of the 2007 first-issue Liberty Bell stamps we've handled looked like they were printed last week.

And if a stamp is borderline — gum a little stubborn, corner slightly soft — it will still usually mail just fine. Postal clerks care that it's authentic and unused, not that it's pretty.

Are Forever Stamps From 2014, 2018, or Any Other Year Still Good?

All of them. There is no cutoff year, no phase-out schedule, no "valid through" date. But since people search for specific years, let's go through the ones we get asked about most:

• Are 2014 Forever stamps still good? Yes. The 2014 flag coils are among the most common stamps we see in office surplus — companies bought them by the roll of 100. Every one is still fully valid.
• 2018 issues? Good. That was a heavy year for booklet formats, and booklets tend to survive storage well because the backing protects the gum.
• 2022 and newer? Obviously good, though we'd barely call those "old." They've been through fewer rate increases, which just means their owners got a smaller head start on value.
• Anything back to 2007? Still valid. The first Forever stamp ever printed will mail a letter today.

The year on a stamp tells you when it was designed, nothing more. Treat it like trivia, not a deadline.

One honest caveat before you go hunting for old stamps online: expiration isn't the risk with aged postage — counterfeits are. Fake stamps have gotten convincing, and they tend to hide in "too good to be true" listings. It's why we inspect and verify every stamp before it ships; you can read exactly how we check authenticity on every stamp we sell.

Frequently Asked Questions

Do Forever stamps ever expire, even after decades?

No. The Postal Service has never set an expiration date on any Forever stamp, and there's no mechanism for one — the stamp's validity is the product. As long as it's genuine, unused, and physically intact, it works. Decades from now, barring some wholesale redesign of the mail system, it will still work.

Are Forever stamps still good in 2025, and will they be good in 2026?

Yes and yes. Nothing changes at year boundaries. A Forever stamp bought in any prior year remains valid through 2025, 2026, and beyond, at the full current one-ounce First-Class rate. No action needed on your part — no exchanging, no topping up.

Can I combine old Forever stamps on a heavier or international letter?

You can. Each Forever stamp counts at the full current one-ounce rate, so two old stamps on one envelope contribute two ounces' worth of the base rate. For heavier mail or international letters, you may slightly overpay compared to exact postage, but the stamps themselves are perfectly acceptable in combination.

Do old Forever stamps lose value when postage rates rise?

The opposite. Rate increases raise the mailing value of every Forever stamp already in circulation. The stamps sitting in your drawer got a raise every time postage went up — which is more than most drawer contents can claim.

Should I do anything special to store Forever stamps long-term?

Keep them flat, dry, and away from heat and sunlight. A folder in a desk drawer indoors is ideal. Skip attics, garages, and cars. Do that, and the stamps will outlast the envelope you eventually stick them on.
