Semipostal Stamps

Semipostal stamps are special USPS issues sold with a fundraising component for a designated cause. They can look similar to ordinary commemorative postage, but their program purpose and sale structure are different. Check the exact issue details before choosing one.

Understand the product type

The amount paid for a semipostal stamp can include more than its postage value because part of the purchase supports the program identified for that issue. Do not infer current availability, contribution amount, or postage treatment from an older design alone; USPS program details can change.

For mailing or subject interest

Buyers may select a semipostal issue for its cause, artwork, or use on qualifying mail. The individual product page should identify the issue and quantity offered. If your main goal is ordinary one-ounce letter postage, compare it with the First-Class Forever stamps collection.

For current program rules, check the specific issue and USPS information rather than applying the rules of one semipostal release to every other release.
