Both Uber and Lyft serve Arizona, including Phoenix and the Phoenix Sky Harbor International Airport (PHX), as well as other cities like Chandler and Tucson. Whether you're visiting the Grand Canyon or Wahweap Marina, you'll have an easy time finding a ride. Uber and Lyft vehicle requirements in Arizona involve an inspection and dictate that vehicles must also be under 14 years old, or under 12 years for Phoenix, Tucson, and Flagstaff. They must also have their company logo displayed on the windshield while in driver mode.
