Does it matter what stamps?

Question

yeah, it sounds stupid but i never had to mail a letter of any sort. im mailing a letter to a friend in austria. how many stamps does that require? and does it matter if i keep using different stamps? and is there a limit on how many stamps i can use?

Answer 1

Go here on the US Postal Service site and put in your information, and it will tell you the cost.

No, you can put as many stamps as you want to on the letter, as long as the address is visible.

Answer 2

You should take a trip to the Post Office and get the correct information about overseas mail.
