Yes, you can send any foreign mail with Forever Stamps. Forever Stamps are unique because they never run out. Using Global Forever Stamps, a one-ounce letter can be sent from the United States to any foreign country.
But since all foreign prices are higher than local prices, customers must add more mail. All foreign mail costs more than mail sent within the same country. This is because when you send a letter or package overseas, you have to pay extra fees.

What happens if you use too few stamps?

If you don’t put enough stamps on an envelope, it will be “postage due” when it gets to the post office. This means that the person who gets the letter will have to pay the difference between what the stamp should have cost and what was used.
