The company also benefited from customers returning to its restaurants in the United States, Canada and Europe following vaccinations, even as rising concerns over the Delta variant of the coronavirus kept consumers away from its chains in other markets.
Chipotle Mexican Grill and McDonald's have also delivered a strong beat in the third quarter, aided by product price hikes and the reopening of seating areas in their restaurants.
"We did see a return to dine-in, yet we saw digital sales go up ... that is still something that is going to continue to grow for us," Yum Brands Chief Executive Officer David Gibbs said on a call with analysts.
Taco Bell, which reintroduced its breakfast menu in the quarter, delivered an 8% jump in system sales - which excludes the impact of foreign currency translation - while KFC's sales were up 3% in the United States.
However, Yum Brands' Pizza Hut division saw its U.S. system sales drop 2% in the quarter, as pizza chains grapple with a slowdown in delivery demand following a surge during last year's lockdowns.
Shares of the company were down 1% at $124.81.
Earlier this month, rival Domino's Pizza Inc posted its first drop in U.S. same-store sales in over a decade amid a tight labor market that created a shortage of drivers.
Yum Brands said it was well-positioned to tackle rising industry-wide inflation and growing labor shortages.
The company reported an adjusted profit of $1.22 per share on revenue of $1.61 billion, beating estimates of $1.08 per share on revenue of $1.59 billion.
