How many ounces can be mailed with a forever stamp

According to the United States Postal Service (USPS), a Forever Stamp can be used to mail a letter weighing up to 1 ounce. This means that if you have a letter that weighs 1 ounce or less, you can mail it with a Forever Stamp and it will be considered a standard first-class letter.

However, if your letter weighs more than 1 ounce, you will need to add additional postage to cover the excess weight. The USPS charges an additional 15 cents for each additional ounce, so if your letter weighs 2 ounces, for example, you would need to add 15 cents to the cost of the Forever Stamp.

Here's a breakdown of the USPS's weight-based pricing for first-class letters:

• 1 ounce or less: $0.55 (Forever Stamp)
• 1-2 ounces: $0.70 (1 ounce + 15 cents)
• 2-3 ounces: $0.85 (2 ounces + 30 cents)
• 3-4 ounces: $1.00 (3 ounces + 45 cents)
• 4-5 ounces: $1.15 (4 ounces + 60 cents)

Keep in mind that these prices are subject to change, so it's always a good idea to check the USPS website or consult with a postal worker for the most up-to-date information.
