Available total stamp quantities: 100, 300, 1,000. Select the package option above to see its format and price. The selected option determines how many stamps are supplied; the cart quantity multiplies that amount.

Postage and mailing use

Each domestic Forever stamp retains the current First-Class Mail one-ounce letter value. Heavier, rigid, square or unusually shaped envelopes may require additional postage. One domestic Forever stamp alone does not cover the standard international letter rate.
