The area code 725 is located in Henderson, Nevada.
Area code 725 serves Henderson, Nevada, and the greater Las Vegas Valley in southern Clark County. It is an overlay to longtime area code 702, created to add more phone numbers as the region grew. The overlay launched in 2014, and callers in the 702/725 region use mandatory 10‑digit dialing for local calls. Henderson sits just southeast of Las Vegas, close to Lake Mead and the Arizona border, making 725 significant for both residents and visitors.
Cities and communities covered by area codes 725/702 include:
The 725/702 area includes major landmarks like the Las Vegas Strip (mostly in Paradise and Winchester), Hoover Dam, Lake Mead National Recreation Area, and Harry Reid International Airport (LAS). Historically, 702 was one of the original U.S. area codes assigned in 1947; in 1998, 775 split off for the rest of Nevada, leaving 702—and later 725—for Clark County. If you see a +1 725 number, it’s from the Las Vegas metro area, including Henderson, and can be assigned to either mobile or landline phones. “Henderson is Nevada’s second-largest city” (U.S. Census Bureau).
