US postage does not expire. Every stamp issued since 1860 remains valid and can be used to send mail today, anywhere the Postal Service operates.
That is a remarkable commitment, and it comes with one condition people miss.
Valid does not mean sufficient
An old denominated stamp is valid for the value printed on it — and no more. A low-value stamp from decades ago is still good for exactly that amount, which does not send a letter at today's rate.
So an inherited sheet is usable, but as part of the total rather than as the whole. Check the face value, add make-up postage to reach the current rate, and it will go.
The stamps that need no arithmetic are the Forever ones.
What Forever actually guarantees
Introduced in 2007 at 41 cents. A Forever stamp bought then — fifteen years on, at a $0.60 rate — still carries a first-class letter with nothing added.
That is the entire product. You are buying carriage, not a fixed amount of money.
Since 2011, almost every stamp sold for first-class mail has been a Forever stamp, so anything bought in the last decade or so already works this way. The denominated stamps that need topping up are generally older than that.
Condition is the real limit
An unused stamp in good condition from any era will be accepted. A damaged one may not — the Postal Service assesses whether it can be verified as legitimate postage, and a torn, faded or heavily creased stamp may fail that test regardless of its age.
So if you are keeping stamps to use later, store them flat, dry and out of direct light. The postage value is permanent; the paper is not.
Current rates
Forever stamps are $0.60, and the international Forever stamp $1.40 for a one-ounce letter abroad.
Rolls, sheets and booklets
Three formats, and the quantities differ enough to matter when ordering:
- Rolls — 20 up to 1,000 stamps. Right for businesses with ongoing volume, and the format that feeds an affixing dispenser. Subscription delivery exists so stock arrives before you run out.
- Sheets — usually 10 to 20. The right size for a small wedding or a holiday mailing.
- Booklets — 16 to 20, folded in a protective cover. The everyday household format.
One buying warning: check the stamp count, not just the price. A 16-stamp booklet and a 20-stamp booklet look similar in a listing and are not the same purchase. This is where most ordering mistakes happen.
Best deals on Forever stamps
Because the value never lapses, buying ahead of an announced rate increase is a straightforward saving on mail you will certainly send. Rolls make the most sense for volume; booklets for occasional use.
Where to buy
The USPS official store, including subscription delivery for rolls, or a verified surplus channel such as www.foreverstampcenter.com for one-off bulk orders and international rates.
The short version
Nothing expires. Older denominated stamps are valid for their printed value and need topping up; Forever stamps need nothing. Store what you keep flat and dry, and check the count in the listing before you order.
