Las Vegas uses two area codes: 702 and 725, both covering the entire Las Vegas valley and all of Clark County. 702 is the original code, assigned in 1947 and the only Nevada area code until 1998. 725 was added as an overlay in 2014 to handle number exhaustion — so a 725 number is just as local as a 702 number. Because two codes share the region, 10-digit dialing is required.
What area code is Las Vegas?
Las Vegas is served by 702 (the primary, original code) and 725(the overlay code added in 2014). Both cover identical geography. When you get a new phone number anywhere in the Las Vegas valley today, it may be issued in either code depending on availability — and both are equally “local.” 702 was one of the original 86 area codes created when the North American Numbering Plan launched in 1947, and it remained the single area code for the entire state of Nevada until 1998.
What's the difference between 702 and 725?
There is no geographic difference — 702 and 725 cover the exact same area. The only practical distinction is age: 702 numbers have been issued since 1947, while 725 numbers have been issued since the 2014 overlay. An overlay adds a second area code to a region instead of splitting it, which means no existing customer had to change their number. The North American Numbering Plan Administrator (NANPA) approved the 725 overlay precisely because 702 was approaching number exhaustion. The cost of the overlay is that callers must dial all 10 digits (area code plus seven-digit number) for every call, even local ones.
Nevada area codes at a glance
| Area code | Region | Major cities | In service since | Time zone |
|---|---|---|---|---|
| 702 | Las Vegas valley / Clark County | Las Vegas, Henderson, North Las Vegas, Boulder City | 1947 (original) | Pacific (PT) |
| 725 | Same as 702 (overlay) | Identical coverage to 702 | 2014 (overlay) | Pacific (PT) |
| 775 | Northern + rural Nevada | Reno, Sparks, Carson City, Elko, Pahrump | 1998 (split from 702) | Pacific (PT) |
What time zone are 702 and 725 numbers in?
Both Las Vegas codes sit in the Pacific Time Zone — the same clock as Los Angeles, three hours behind New York. Nevada observes daylight saving time, so the valley runs on PST (UTC-8) in winter and PDT (UTC-7) in summer. If a 702 or 725 number calls you at 9am Eastern, it is 6am in Las Vegas — a detail worth remembering before returning business calls.
Is a call from a 702 or 725 number legitimate?
Usually, yes — these are the everyday codes for over 2.3 million Clark County residents and virtually every Las Vegas business, including our own team at (702) 637-1759. But because “Las Vegas” carries instant name recognition, scammers do spoof 702 numbers for fake casino comps, prize notifications, and hotel-deal robocalls. The area code itself proves nothing either way: legitimate businesses will be reachable at a published number you can verify independently, and no real casino or resort demands gift cards or wire transfers by phone. If a “Vegas” call pressures you about winnings you never entered for, hang up.
How do you dial a Las Vegas number?
Within the US, dial all ten digits: 702-XXX-XXXX or 725-XXX-XXXX (seven-digit local dialing ended with the 2014 overlay). From abroad, add the US country code: +1 702 XXX XXXX — from most of Europe that is 00-1-702, and the +1 format works from any mobile phone worldwide. Calls between 702 and 725 numbers are ordinary local calls; the two codes are one seamless calling area.
What cities are in the 702 and 725 area codes?
The 702/725 region is essentially all of Clark County. That includes Las Vegas, Henderson, North Las Vegas, Boulder City, Mesquite, Laughlin, Indian Springs, Searchlight, and the Mount Charleston communities. If a home you are considering sits in the Las Vegas metro, its landline and most cell numbers will carry a 702 or 725 prefix.
What are the other Nevada area codes?
Outside the Las Vegas metro, Nevada uses a single area code: 775. The 775 code was split off from 702 in 1998 and covers northern and rural Nevada — including Reno, Sparks, Carson City, the Nevada side of Lake Tahoe, Elko, Fallon, and Pahrump. So in practice the entire state runs on just three area codes: 702 and 725 for the Las Vegas valley, and 775 for everywhere else.
Why does the area code matter when moving to Las Vegas?
For most relocating buyers it is a small but real detail. You can keep your existing out-of-state cell number when you move — federal number-portability rules let you port it to a new carrier in Las Vegas — so a 702 number is optional, not required. Many business owners do want a 702 number for local credibility with Las Vegas customers. And because 725 has been in circulation for over a decade, a 725 number no longer signals “newcomer” the way it briefly did right after 2014. If you are planning a move, our Moving to Las Vegas guide and relocation checklist walk through the practical setup steps, and military families relocating to Nellis should see the Nellis AFB relocation guide.
Area-code assignments are governed by the North American Numbering Plan Administrator (NANPA) and overseen for Nevada by the Public Utilities Commission of Nevada (PUCN).
