It is one of the fastest-growing franchises in the world. As of June 2017, Subway had approximately 42,000 locations in 111 countries worldwide, all independently owned.
These locations are largely concentrated in North America, with 24,350 in the United States, 3,155 in Canada, and 929 in Mexico; this is almost as many U.S. locations as McDonald’s and Starbucks combined. Outside North America, the countries with the most locations are Australia (approximately 1,400), Brazil (approximately 2,200), and the United Kingdom (approximately 2,300).
As of October 2019, had 41,512 locations in more than 100 countries. More than half its locations (23,928 or 57.6%) are in the United States. It also is the largest single-brand restaurant chain and the largest fast food restaurant chains by their number of locations in the world.
Subway's core product is the submarine sandwich (or "sub"). In addition to these, the chain also sells wraps, salad, paninis, and baked goods (including cookies, doughnuts, and muffins).
Subway's best-selling sandwich, the B.M.T. (short for "Biggest, Meatiest, Tastiest"), contains pepperoni, salami, and ham. The name originally stood for Brooklyn Manhattan Transit.
Subway also sells breakfast sandwiches, English muffins, and flatbread. In 2006, "personal pizzas" debuted in some US markets. These are made to order (like the subs) and heated for 85 seconds. Breakfast and pizza items are only available in some stores.
