Stamps generally do not expire as long as they can still be recognized as valid postage. This means that unused stamps are good indefinitely, although their price at purchase may not cover the full cost of postage rates if those rates have increased since the stamp's purchase. Forever stamps, for example, can be used regardless of when they were purchased, covering the full postage cost of a one-ounce standard letter anytime in the future.
