USPS Forever Stamps are a type of postage stamp that holds their value regardless of future postage rate increases. These stamps were introduced in 2007 and were designed to provide a long-term solution to the challenge of fluctuating postal rates. Whether you purchase them today or in the future, these stamps will always cover the cost of sending a standard-sized, one-ounce letter within the United States. However, their utility extends beyond domestic postage needs. Forever Stamps can also be used for international mail, making them a versatile option for those who send letters and packages across borders.<span style="white-space: pre;"> usps buy forever stamps</span>
