Area codes serving Las Vegas
Las Vegas sits in Nevada, part of the West region and the Pacific Time zone. Its numbers are spread across an overlay of 2 codes that all cover the same ground: 702, 725.
The original code is 702. As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.
How to pick an area code for a new number
When you activate a new line in Las Vegas, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 702), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.
Dialing in Las Vegas
Because Las Vegas is an overlay area, 10-digit dialing is mandatory: always dial the area code plus the seven-digit number, even for a neighbor. See 10-digit dialing and overlay area codes for the background. For every code in Nevada, visit the Nevada area codes page.
