Semipostal Stamp Program Law and Legal Definition

Semipostal stamp program is a fundraising program undertaken by the U.S. Postal service (USPS). The program is regulated by the Semipostal Authorization Act. Semipostal stamps are stamps that are sold for a price that exceeds the postage value of the stamp. The print quantities of semipostal stamps are determined by the USPS.

Pursuant to 39 CFR 551.2, semipostal stamps are stamps that are sold for a price that exceeds the postage value of the stamp. The difference between the price and postage value of semipostal stamps, also known as the differential, will be contributed to fund causes as determined by the USPS after offsetting for reasonable costs incurred. The office of Stamp Services determines the print quantities of semipostal stamps. The use of semipostal stamps shall be voluntary on the part of postal patrons.
