WASHINGTON (AP) â It's going to cost you a few pennies more to mail a letter. The cost of a first-class postage stamp is now 49 cents â 3 cents more than before. Regulators approved the price hike in December, and it went into effect Sunday.
The Global Forever stamp can be used to mail a postcard or 1-ounce letter-size letter anywhere in the world by First Class Mail International delivery, according to the U.S. Postal Service. In 2014, a Global Forever stamp costs $1.15. Heavier letters and packages require more postage.
