How many stamps does it take to mail a postcard from Budapest to the us?

To mail a postcard from Budapest to the U.S., you typically need one international stamp. As of my last update, the cost for sending a postcard internationally from Hungary is around 200-300 HUF, depending on the current postal rates. It's always best to check with the Hungarian postal service or their official website for the most accurate and up-to-date information on postage rates.
