Do Forever Stamps Ever Lose Their Value?

The question of whether Forever stamps lose their value is a common concern as postage rates periodically adjust. This article clarifies the unique design and function of Forever stamps, addressing how they retain their utility over time despite changes in postal rates.

The Design and Function of Forever Stamps

Forever stamps, introduced by the United States Postal Service (USPS) in 2007, are non-denominated. This means they do not have a price printed on them. Instead, they are always valid for the current First-Class Mail 1-ounce letter rate, regardless of when purchased. This design ensures a Forever stamp bought at an older, lower price still covers the cost of a standard 1-ounce letter even if the postage rate increases.

This feature means Forever stamps do not lose their value for their intended use. For instance, a stamp bought when the First-Class rate was $0.41 would still be equivalent to the current rate of $0.78 as of July 13, 2025. The stamp’s value automatically adjusts upwards with each rate increase, providing a hedge against rising postage costs. This makes them a convenient and economical option for sending standard letters.

Applying Forever Stamps to Various Mail Types

While a single Forever stamp covers the cost of a standard 1-ounce domestic First-Class letter, additional postage is required for mail exceeding this basic weight or size. For letters weighing more than one ounce, additional stamps are necessary. The cost for each additional ounce varies by current rates.

Oversized envelopes or those with unusual shapes, such as “flats” or “nonmachinable” items, also require more postage. These mail pieces may incur a nonmachinable surcharge or be subject to higher “large envelope” rates. For international mail, a regular Forever stamp can be used, but it must be supplemented with additional stamps to meet the higher international postage rate. A specific Global Forever stamp can also be used. The need for additional postage in these scenarios indicates the mail item’s cost exceeds the value of a single First-Class 1-ounce stamp.

The Purpose Behind Forever Stamps

The USPS introduced Forever stamps to benefit both consumers and the postal service. For mailers, these stamps offer convenience, eliminating the need to purchase “make-up” stamps when rates change. This allows individuals and businesses to stock up on stamps without concern they will become obsolete or require supplemental postage for standard letters.

From the postal service’s perspective, Forever stamps reduce the administrative burden and costs associated with printing specific denomination stamps for every rate adjustment. Before their widespread adoption, the USPS printed and distributed millions of low-denomination stamps to allow mailers to meet new rates. By using non-denominated Forever stamps, the USPS streamlines operations, leading to cost savings and a more efficient postage system.
