How Do Forever Stamps Work? Forever Stamps are ideal for mailing normal-sized, **one-ounce** letters within the United States. If you suspect that your letter may weigh more than one ounce, be sure to weigh it prior to affixing a Forever Stamp, as heavier letters will be returned due to lack of postage.

**1 ounce**. A First-Class stamp rate is currently 55 cents. You will not be able to send an envelope of more than 1 ounce with one stamp.
