There were more than 8,000 U.S.-based 7-Eleven franchises as of 2016, and for almost any other company in the world, that’s a ton. But, that number is nothing compared to 7-Eleven’s 50,000+ international franchises. That number is growing wildly, too. In 2007, there were only 26,680 franchises outside the U.S.
