What is a Forever Stamp
A Forever stamp is a First-Class Mail stamp sold by the United States Postal Service (USPS) that remains valid for the delivery of a one-ounce letter, regardless of future price increases. It is a convenience tool for consumers who want to avoid partial or additional postage when rates change. The value of a Forever stamp is tied to the price of a First-Class Mail one-ounce letter, so its real cost in postage stays current even when nominal prices rise.

When to Use Forever Stamps
Use Forever stamps for any 1-ounce letter mailed within the United States via First-Class Mail. They cover the base delivery price for letters up to 1 ounce; additional ounces require extra postage in the form of either more Forever stamps or additional-ounce stamps. Forever stamps cannot be used for flat-rate envelopes, packages, or international mail without calculating weight and additional fees.
Rules to Remember
- Forever stamps cover 1 ounce of First-Class Mail only.
- For letters over 1 ounce, add either more Forever stamps or Extra Ounce stamps to cover the full weight.
- Do not use Forever stamps for postcards, flats, or international destinations unless combined with other postage to cover exact weight and destination.
Does It Make Sense to Buy Forever Stamps in Bulk
Forever stamps act as a partial inflation hedge because they retain value even when postal rates increase. If you regularly send first-class letters, purchasing Forever stamps when prices are stable can reduce future trips to the post office or the need to purchase additional stamps at higher rates. However, avoid buying in very large quantities if you lack secure, dry storage, as stamps can be damaged. Consider buying only what you expect to use within 6–12 months for personal use; businesses with higher volumes may benefit more from bulk purchases aligned with their mailing cadence.
Alternatives and Supplemental Options
For letters that exceed 1 ounce, you have two practical paths: add more Forever stamps or buy Extra Ounce stamps. For larger or heavier items, you must use different services such as USPS Retail Ground, Priority Mail, or Priority Mail Express, each with its own pricing structure. Online postage services and Click-N-Ship allow you to print Forever stamps and other labels at home, which can be convenient for variable mailing needs.
Common Mistakes to Avoid
Using Forever stamps on items that exceed 1 ounce without adding postage is a frequent error that results in delivery delays. Another mistake is using them on incorrect mail types, such as international letters or heavy flats, where specific rates apply. Always weigh your item, confirm the destination, and verify the required class of mail before applying a Forever stamp to avoid returns or additional fees.
