International Postage For Postcards. To ship a postcard to france, you will need $1.30 in postage (per the price increase), which can be covered with one global first class forever stamp ($1.30) or three first class forever stamps ($1.74). This calculates the total postage to send mail from the united states to any of various countries.
Please note that it does not include the indirect costs of sending someone to the post office to fill out and sign customs forms, etc. As of 2015, the post office charges $1.15 to send a single postcard internationally. That’s expensive for postcard mailing, let alone the cost of the card.
