How Forever Stamps Work
Forever stamps maintain their usefulness for 1-ounce First-Class letters regardless of future price changes. This makes them a practical option for standard correspondence. There are specific rules around weight, size, and shape that determine whether a Forever stamp is sufficient. Non-standard items may require additional postage or different mailing services. Understanding these parameters helps ensure smooth processing and delivery.
Key rules for using First-Class Forever stamps
- Weight limit: 1 ounce maximum for a standard letter.
- Size limits: Must fit within length 6-1/8 inches, height 3-1/2 to 6-1/8 inches, thickness range 0.007 to 0.25 inches.
- Shape: Letters must be uniform and relatively flat; rigid or oddly shaped items may need different handling.
- Delivery: Designed for U.S. domestic First-Class Mail delivery within the United States.
- International: Forever stamps are not sufficient for international mail; specific International Forever or additional postage is required.
When to Use a First-Class Forever Stamp
Use a First-Class Forever stamp for standard personal or business letters that weigh up to 1 ounce and meet size guidelines. It is suitable for single envelopes, thank-you notes, personal correspondence, and bills. For heavier letters, flats, or parcels, additional postage or services such as Postcards, Priority Mail, or Retail Ground may be needed. Planning mailings around these rules can prevent delays and extra costs.

You can purchase First-Class Forever stamps at post offices, online via USPS.com, at many retail locations, and in some grocery and pharmacy stores. Buying booklets or full sheets in advance can reduce the per-stamp cost and ensure you have stamps on hand.
