Can you mail a letter with a forever stamp

A Forever Stamp is a type of postage stamp issued by the United States Postal Service (USPS) that is valid for first-class mail weighing up to 1 ounce, regardless of the current postage rate.

Yes, you can mail a letter with a Forever Stamp, as long as the letter weighs 1 ounce or less. Here are some guidelines to keep in mind:

1. Weight: The letter must weigh 1 ounce or less. If your letter weighs more than 1 ounce, you'll need to add additional postage.
2. Size: The letter must be a standard size, which is typically 3.5 inches high x 6.125 inches long x 0.007 inches thick.
3. Destination: The Forever Stamp is valid for domestic first-class mail to any destination within the United States, including Puerto Rico, Guam, and the U.S. Virgin Islands.
4. Content: The letter can contain any type of content, including text, images, and attachments, as long as it's not oversized or irregularly shaped.

If you're unsure whether your letter will fit within the 1-ounce weight limit, you can weigh it using a postal scale or consult with a postal worker at your local post office.

Remember that Forever Stamps are only valid for first-class mail, so if you need to send a letter that requires additional services, such as certified mail or priority mail, you'll need to use a different type of postage.
