Where area code 702 is used

Area code 702 generally covers all of Clark County, the most populous of Nevada's 17 counties. Las Vegas is the county seat.

Clark County has five incorporated cities: Las Vegas, Henderson, North Las Vegas, Boulder City, and Mesquite. It also has unincorporated communities such as Paradise, Spring Valley, Enterprise, and Sunrise Manor, which appear on the county's map of unincorporated townships.

Area code 775 is the other Nevada code, created in December 1998. An area code does not show which street or building the caller is on.

Time zone: Pacific Time

Clark County is on Pacific Time. The IANA time zone database lists Nevada, except West Wendover, under the US Pacific zone, which it represents with Los Angeles.

The same database sets the US daylight saving rule that has applied since 2007. Daylight time starts on the second Sunday in March and ends on the first Sunday in November, both at 2:00 local time.

Dialing history: the 2014 change

Before 10-digit dialing became mandatory, the PUC asked customers to switch early. Seven-digit dialing still worked until May 3, 2014.

• Until May 3, 2014, seven-digit dialing still worked, and customers were asked to start 10-digit dialing before that date.
• On May 3, 2014, 10-digit dialing became mandatory for all local calls. Seven-digit local calls were no longer completed.

For businesses, the change applies to phone systems, speed dials, fax and alarm lines, and other equipment programmed with seven-digit numbers. Update them before the mandatory date.

Neighboring codes in Nevada

702 and 725 cover Clark County, and 775 is the other Nevada code. The table shows how each code relates to 702.

Overlay code 725: what it means for 702

An overlay adds a new area code to the same geographic area. Under the 725 overlay, new telephone lines in the 702 area may be assigned 725 numbers, starting June 3, 2014. Existing numbers keep their 702 area code.

Because the two codes share the same territory, a Las Vegas business may have a 702 number or a 725 number. The area code does not show which building or floor a number belongs to.

Number supply: projections for 702

An area code has a limited pool of numbers, and relief planning decides when a new code is needed. NANPA's April 2025 exhaust analysis, based on numbering data as of March 1, 2025, lists the 702/725 exhaust date as 3Q 2077. That is the most recent NANPA report we could retrieve.

Exhaust dates change with each NANPA report. The October 2025 report could not be retrieved, so check the latest NANPA exhaust analysis before you plan around a specific code.

How to dial a 702 number

A 702 or 725 number has an area code followed by a seven-digit number. Because 702 and 725 overlap, 10-digit dialing is required for all local calls within the territory.

For local calls within the 702 and 725 territory, dial 10 digits: the area code followed by the seven-digit number. Long-distance calls use 1 + area code + telephone number.

Caller ID and scam calls

The FTC warns that scammers can make any name or number show up on caller ID. That is called spoofing, and it means a 702 number on your screen is not proof of who is calling.

• Do not rely on caller ID to tell you who is calling.
• Hang up on robocalls, and do not press any numbers, since that may lead to more calls.
• Use call blocking. The FTC says call blocking is your best defense against unwanted calls.
• To report a call, give the number that received it, the number on your caller ID, and any callback number.

Using a 702 or 725 number in Las Vegas

702 is a geographic code for Clark County, and the 725 overlay may assign new numbers in the same territory from June 3, 2014. A Las Vegas business may therefore have either code, and the code alone does not show which branch or department answers. A business with offices outside Clark County may need numbers from 775, the other Nevada code. Check with your provider.

Whether a specific 702 or 725 number is available depends on your phone provider and its current inventory. Route calls from both codes to the same queue, so callers get the same service whichever code appears.

Important: Confirm availability with your provider before you plan a campaign or print a number on materials.

Before you use a 702 number

• Confirm the number is available from your provider, and get its terms in writing.
• Program 10-digit dialing for both 702 and 725 in phone systems, speed dials, and fax or alarm lines. It has been mandatory for local calls since May 3, 2014.
• Route calls from both 702 and 725 to the same team, since the two codes share one territory.
• If you have an office outside Clark County, check whether its numbers use 775, which is a separate code.
• Plan for caller ID. A local number does not prove who is calling, and caller ID can be spoofed.
