Can one forever stamp mail a letter in america

In the United States, a Forever Stamp is a type of postage stamp that can be used to mail a letter weighing up to 1 ounce, regardless of the current postal rate. The Forever Stamp is valid for first-class mail, which includes letters, postcards, and flats (small, flat packages).

As long as the letter weighs 1 ounce or less, you can use a Forever Stamp to mail it, and the postage will be sufficient. However, if the letter weighs more than 1 ounce, you'll need to add additional postage to cover the increased weight.

Here are some important details to keep in mind:

  1. Weight limit: Forever Stamps are valid for letters weighing up to 1 ounce. If your letter weighs more than 1 ounce, you'll need to add additional postage.
  2. Size limit: Forever Stamps are valid for standard-sized letters (up to 11.5 inches long, 6.125 inches wide, and 0.25 inches thick).
  3. Destination: Forever Stamps are valid for domestic mail (within the United States) and international mail to most countries. However, some countries have specific postage requirements, so you may need to add additional postage for certain destinations.
  4. Postage rate changes: While the Forever Stamp is valid forever, the postage rate may change over time. If the postage rate increases, you can use the Forever Stamp to mail a letter, but you won't be able to use it to mail a heavier or larger letter.

To ensure your letter is properly postage, you can use the USPS Postage Calculator or consult with a postal worker at your local post office.
