Can use forever stamps international mail

In the United States, Forever Stamps are only valid for domestic first-class mail, which means they can be used to send letters and cards weighing up to 1 ounce within the United States. They are not valid for international mail.

If you need to send mail internationally, you will need to use a different type of stamp or postage. The cost of international postage varies depending on the weight, size, and destination of the mailpiece, so you'll need to use a postage calculator or consult with a postal service representative to determine the correct postage.

Here are some options for sending international mail:

1. Global Forever Stamps: These stamps are specifically designed for international mail and can be used to send letters and cards weighing up to 1 ounce to most international destinations. However, they are not valid for all countries, so be sure to check the USPS website for a list of eligible destinations.
2. International Postage Rates: You can use the USPS website to calculate the cost of international postage based on the weight and size of your mailpiece. You can also use a postage calculator at a post office or online.
3. Priority Mail International: This service is ideal for sending larger or heavier packages internationally. You can use a Priority Mail International label, which includes tracking and insurance.
4. First-Class Package International Service: This service is similar to Priority Mail International, but it's used for smaller packages and letters.

Remember to always check the USPS website or consult with a postal service representative for the most up-to-date information on international postage rates and regulations.
