What Is a Forever Stamp? A Complete Guide

A Forever stamp is a U.S. postage stamp that always pays the current price of a standard 1-ounce First-Class Mail letter, no matter when you bought it or what you paid for it. Buy one today, keep it in a drawer for ten years, and it will still mail a 1-ounce letter — even if postage rates have gone up several times in between. That single feature is why Forever stamps have become the default stamp for most households in the United States.

This guide explains how Forever stamps work, what one stamp does and does not cover, how their value compares with older denominated stamps, and how to buy and use them well. It is part of our Postage & Stamp Guides center.

How a Forever Stamp Works

Most postage stamps are printed with a fixed value — 29 cents, 58 cents, and so on. If rates rise after you buy them, those stamps are still worth exactly the amount printed on them, and you have to add small extra stamps to make up the difference.

A Forever stamp works differently. Instead of a fixed number of cents, it carries a service promise: it is always worth the prevailing single-piece First-Class Mail letter price for the first ounce. When the U.S. Postal Service raises letter prices, every unused Forever stamp you own automatically becomes worth the new price. When prices stay the same, so does the stamp’s value.

You can recognize a Forever stamp by the word “FOREVER” printed on it, usually alongside “USA” and the current postage class. There is no expiration date, and USPS states that Forever stamps “will never expire, even if the First-Class postage rate goes up.”

What Is a Forever Stamp Worth Right Now?

As of the current USPS price list (in effect since July 12, 2026), a Forever stamp is worth $0.82 — the price of mailing a standard 1-ounce letter within the United States. Before July 12, 2026, the value was $0.78. Anyone holding Forever stamps bought at $0.78, $0.68, $0.55, or any earlier price saw their value rise to $0.82 automatically, with nothing to exchange or upgrade.

Here is what one Forever stamp covers — and what it does not:

Mailpiece	Current postage	One Forever stamp enough?
Standard rectangular letter, up to 1 oz	$0.82	Yes
Letter, up to 2 oz	$1.11	No — add 29¢ for the extra ounce
Standard postcard	$0.65	Yes, but it overpays by 17¢
Square or rigid letter, 1 oz	$1.31	No — a 49¢ nonmachinable surcharge applies
Large envelope (flat), 1 oz	$1.69	No — flats start at a higher rate
Letter to another country, 1 oz	$1.75	No — use a Global Forever stamp instead

A Short History of the Forever Stamp

USPS introduced the Forever stamp in April 2007, priced at 41 cents and featuring the Liberty Bell. The idea was to spare customers (and the Postal Service) the hassle of buying 1- and 2-cent “make-up” stamps every time rates changed, and to let people stock up on postage without worrying that it would lose value.

The concept proved popular enough that USPS extended it. Over the following years, Forever pricing was applied to postcard stamps, additional-ounce stamps, and the round Global Forever stamp for international letters. Today, nearly all stamps USPS sells for everyday letter mail are Forever products, and denominated stamps are mostly sold in small values for making up exact postage.

Forever Stamps vs. Denominated Stamps

Both kinds of stamps remain valid for postage, but they behave differently when prices change:

• Forever stamps track the current 1-ounce letter price. Their value adjusts upward when USPS raises rates.
• Denominated stamps (a printed cent value) are frozen at face value forever. A 25-cent stamp from the 1990s is still worth exactly 25 cents toward postage today.
• Additional-ounce stamps are sold at the current price for each extra ounce of a letter — currently 29 cents — and are the tidy way to pay for a 2- or 3-ounce letter alongside one Forever stamp.
• Postcard stamps are Forever products priced at the postcard rate, currently $0.65.
• Global Forever stamps cover a 1-ounce letter or postcard to any country in the world, currently priced at $1.75.

If you have a drawer of older stamps of mixed values, they are almost certainly still usable. Our guide Can You Use Old Forever Stamps? explains the rules for combining old stamps and the few conditions that make a stamp unusable.

What a Forever Stamp Does Not Cover

The most common mailing mistakes with Forever stamps come from assuming one stamp covers any envelope. It does not. A single Forever stamp pays for exactly one thing: the first ounce of a standard, machinable First-Class letter. You will owe more postage when:

• The letter weighs more than 1 ounce. Each additional ounce, up to the 3.5-ounce letter maximum, costs 29 cents.
• The envelope is square, rigid, lumpy, or has clasps, string, or buttons. These pieces cannot run through USPS sorting machines and carry a 49-cent nonmachinable surcharge — a 1-ounce square envelope costs $1.31 to mail. See Do Greeting Cards Need Extra Postage? for the full list of triggers.
• The envelope is oversized. Anything beyond letter dimensions (longer than 11.5 inches, taller than 6.125 inches, or thicker than 0.25 inch) is priced as a large envelope, starting at $1.69.
• The letter is going abroad. International letters start at $1.75 per ounce and follow different weight steps; a Global Forever stamp is the simplest way to pay.

Reading an Old Stamp Book: Which Stamps Are “Forever”?

If you are sorting through stamps bought in different years, the distinction is printed right on each stamp. A Forever stamp says “FOREVER” in place of a cent value — designs range from the Liberty Bell and the U.S. Flag to flowers, holiday artwork, and commemorative subjects, and every one of them is worth the same $0.82 today. A stamp with a number of cents printed on it is a denominated stamp: still valid, but permanently worth that printed amount.

Two special cases are worth recognizing. The round stamp labeled “GLOBAL FOREVER” is the international version, currently worth $1.75 toward mail to other countries. And stamps marked “ADDITIONAL OUNCE” are Forever-family products for extra weight — worth the current additional-ounce price of 29 cents each, not the full first-ounce price. Keeping those three types straight is most of what there is to know about a mixed stamp drawer.

Worked Examples: What Common Mailings Actually Cost

Abstract prices are easier to trust when you can see them applied to real envelopes. Three everyday cases, all at current prices:

• A holiday card with a photo inside, weighing 2.4 ounces. Weight rounds up to the 3-ounce step. The card itself is a standard rectangular envelope, so no surcharge applies: $0.82 for the first ounce plus 29 cents for each of the two additional ounces = $1.40. Pay it with one Forever stamp and two additional-ounce stamps. Two Forever stamps would put $1.64 on the envelope — 24 cents more than needed.
• A square 1-ounce party invitation. Weight is fine; shape is not. The 49-cent nonmachinable surcharge brings the total to $1.31: one Forever stamp plus 49 cents in other stamps (an additional-ounce stamp and smaller denominations can make up the difference).
• A vacation postcard to a friend across the country. Postage is the flat postcard rate of $0.65 regardless of distance. A postcard stamp is the exact tool; a Forever stamp also works but wastes 17 cents.

The pattern in all three: one Forever stamp anchors the first ounce of letter-rate mail, and everything else — extra ounces, surcharges, different mailpiece classes — is added on top of it or priced separately.

Should You Stock Up Before a Price Increase?

Because a Forever stamp’s value rises with letter prices, buying stamps shortly before an announced USPS price increase locks in the lower price for future mailings. This is not a loophole — it is the way the product is designed to work, and USPS sells Forever stamps in books of 20 and coils of 100 partly so households and small businesses can do exactly this.

Two honest qualifications: first, the savings per stamp are a few cents, so stocking up makes the most sense if you genuinely mail letters and cards throughout the year. Second, only buy from reliable sellers (see below). The market for heavily “discounted” Forever stamps from unknown online sellers is a known counterfeit problem area; a fake stamp is worth nothing, which erases any saving.

Common Mistakes With Forever Stamps

Most Forever stamp problems are not about the stamp itself — they are about what senders assume it covers. The recurring ones:

• Using a second Forever stamp for a heavy letter. A 2-ounce letter costs $1.11, not $1.64. Two Forever stamps overpay by 53 cents; one Forever plus one additional-ounce stamp is exact. On a 3-ounce letter ($1.40), two Forever stamps still overpay by 24 cents.
• Assuming “Forever” means “covers anything.” The promise is tied to one product: a standard 1-ounce letter. Square, rigid, oversized, and international pieces all need more, as the table above shows.
• Putting a Forever stamp on a postcard out of habit. It works, but you are spending $0.82 on $0.65 of postage. If you mail postcards regularly, postcard stamps save the difference.
• Trusting deep-discount stamps from unfamiliar sellers. Counterfeit Forever stamps sold well below face value are a known problem, and USPS has warned buyers about them. A counterfeit is not worth $0.82 — it is worth nothing, and mail bearing it can be delayed or returned. The buying list below sticks to established channels.
• Letting stamps get damaged in storage. Forever stamps never expire, but torn, taped, or water-damaged stamps can be refused. A dry drawer or envelope keeps a book of stamps usable for years.

Buying and Using Forever Stamps in Atlanta

This site is edited from Atlanta, and most of the mail we talk about starts at a kitchen table somewhere between Midtown and Decatur. The routines below are the ones that work here — the prices are national, but the habits are local.

Where Atlanta households actually buy stamps. The surest source is the counter of any Post Office, where books of 20 Forever stamps sell at face value — $16.40 for a book at today’s price — and clerks will weigh a questionable envelope for free while you are there. Beyond the counter, most large grocery and drugstore chains in the Atlanta area sell books of Forever stamps at the checkout or customer-service desk, again at face value, and warehouse clubs in the metro area sell larger-value packs for households and small offices that mail in volume. Buying stamps while you are already buying groceries is the December time-saver: the one trip you skip is the mid-December Post Office line.

A kitchen-table example, Midtown to everywhere. Say you are sending three pieces from an apartment in Midtown (30308): a birthday card to a friend in Savannah, a signed contract to Chicago, and a thank-you note to Seattle. All three are standard letters under an ounce, so all three cost exactly the same — one Forever stamp each, $0.82. Distance does not enter letter pricing at all. What changes the bill is never the destination; it is the envelope. If the Savannah card is square, it costs $1.31. If the Chicago contract runs to six pages and weighs 1.6 ounces, it costs $1.11. The Seattle note costs $0.82 even though it travels three times as far as the other two combined.

Spotting counterfeit stamps before they reach your envelopes. Counterfeit Forever stamps are the one genuinely bad buy in this market, and they are usually sold the same way: online listings and social-media ads offering stamps at 40–60% of face value, often in bulk, often shipping from overseas. Genuine postage is essentially never legitimately discounted like that. On the stamps themselves, warning signs include blurry or slightly off-register artwork, colors that look washed out next to a book bought at the counter, perforations that are uneven or merely printed on rather than actually punched, and flimsy paper without the usual feel of a stamp sheet. If a deal looks too cheap to be postage, it is decoration, not postage — mail sent with counterfeits can be delayed, returned, or treated as unpaid. When in doubt, take the stamps to a Post Office counter and ask before you mail a season’s worth of cards with them. For the complete inspection — ink, microprinting, die-cut edges, paper, tagging, and the correct way to run the ultraviolet test — work through how to tell if Forever stamps are real.

Frequently Asked Questions

Do Forever stamps expire?

No. USPS guarantees they remain valid for the 1-ounce letter rate indefinitely.

Can I use a Forever stamp on a package?

You can apply stamps to packages, and their value counts toward the total postage — but a single Forever stamp comes nowhere near package prices, and for anything beyond a letter or flat, printed labels or counter service are far more practical.

Can I use a Forever stamp for international mail?

Its $0.82 value counts toward the total, but a 1-ounce international letter costs $1.75, so you would need additional stamps. A Global Forever stamp is the right tool.

Does a Forever stamp work in every state and territory?

Yes — the rate is national, including Alaska, Hawaii, Puerto Rico, and U.S. territories.

What if my Forever stamp is damaged?

Unused but torn or illegible stamps can be refused. Stamps in normal condition, however old, are fine.

Can I use a Forever stamp on a Christmas card?

Yes, if it is a standard rectangular card up to 1 oz — that is exactly what one Forever stamp ($0.82) covers. Square, heavy, or embellished cards need more; see How Many Stamps Do Christmas Cards Need?.

How many Forever stamps do I need for a 2-ounce letter?

One Forever stamp plus 29¢ for the second ounce ($1.11 total) — use one additional-ounce stamp, not a second Forever stamp, unless you are happy to overpay.

Can I put a Forever stamp on a large envelope?

Yes — its $0.82 value counts toward the large-envelope price, but a 1-ounce flat starts at $1.69, so you would need at least another 87 cents of stamps alongside it. A single Forever stamp alone leaves a flat badly underpaid.

What happens if I mail a letter with only a Forever stamp when it needed more postage?

USPS may return it to you for the additional amount or deliver it with postage due collected from the recipient. Neither is a disaster, but both are avoidable by weighing anything that feels heavier or thicker than a normal letter.

The Bottom Line

A Forever stamp is prepaid postage for a 1-ounce First-Class letter whose value floats with USPS prices, so it never becomes obsolete. At today’s $0.82 rate it covers most ordinary letters and greeting cards on its own. Just remember its limits — extra ounces, square or rigid envelopes, large envelopes, and international mail all cost more — and it is the simplest postage product most people will ever need.
