Area code 725 is an overlay of 702, serving the Las Vegas metropolitan area in southern Nevada. Introduced in 2014 due to rapid population and business growth, 725 is used for new phone lines throughout Las Vegas, Henderson, and North Las Vegas. The region is known globally for its entertainment industry, casinos, nightlife, and events, and has also grown as a hub for sports, logistics, and tech. Ten-digit dialing is mandatory. While 702 carries more legacy recognition, 725 is becoming increasingly common and reflects Las Vegas’s ongoing expansion and modernization.
