Forever Stamps vs Other Stamp Types

Not every stamp is meant for the same type of mail. Forever Stamps are commonly used for many standard First-Class Mail letters within the United States, while postcard, international, and two-ounce stamps are designed for different mailing needs.

Basic Differences

  • Forever Stamps: Commonly used for many standard domestic letters.
  • Postcard Stamps: Intended for eligible postcards that meet postcard requirements.
  • International Stamps: Used for eligible international letters or cards.
  • Two-Ounce Stamps: Useful for heavier mailpieces such as some invitations or cards.

Check Before Mailing

Before sending cards, invitations, or business mail, confirm weight, size, shape, and destination. Square, rigid, thick, oversized, or international mailpieces may require more postage than a standard letter.

For general domestic letters, browse Forever Stamps. For invitations and special stationery, see Love Stamps.
