Area Code for Phoenix

The Phoenix metro area uses three area codes — 602 (central Phoenix), 480 (East Valley including Scottsdale and Tempe), and 623 (West Valley including Glendale and Peoria) — plus 928 for the rest of Arizona.

Each code carries its own geography, history, and cultural identity. Knowing the difference matters whether you’re verifying a caller, building local trust for your business, or choosing a number that signals the right neighborhood to Phoenix customers.

What’s the area code for Phoenix?

Three area codes serve the Phoenix metropolitan area under the North American Numbering Plan (NANP):

Code	Established	Coverage	Notes
602	1947	Central Phoenix, downtown, Ahwatukee, Cave Creek	Original AZ code; most established
480	1999	East Valley — Scottsdale, Tempe, Mesa, Chandler, Gilbert, Paradise Valley	Tech corridor, Scottsdale Old Town
623	1999	West Valley — Glendale, Peoria, Surprise, Sun City, Avondale, Buckeye	Retirement communities, growth corridor

All three codes fall in the Mountain Standard Time (MST) zone, UTC−7 year-round. Arizona does not observe Daylight Saving Time (the only contiguous US state that opts out), so during summer the state is on the same clock as California PDT.

For the broader state: area code 520 covers Tucson and southern Arizona, while 928 covers the rest — Flagstaff, Prescott, Yuma, Lake Havasu City, and the White Mountains.

Phoenix metro area codes by region

602 — Phoenix proper

Area code 602 is the heartbeat of central Phoenix. It covers the downtown core, the Camelback Corridor, and neighborhoods running from Cave Creek in the north to Ahwatukee in the south.

Major 602 locations include:

• Downtown Phoenix — city hall, the Talking Stick Resort Arena corridor, light rail spine
• Midtown — the arts district, Heard Museum, Phoenix Art Museum
• Camelback Corridor — major corporate offices, Biltmore area
• North Phoenix — areas above Union Hills Drive on the Phoenix city boundary
• Ahwatukee — the southernmost Phoenix neighborhood, technically 602 despite East Valley geography

602 is the code that locals associate with Phoenix itself — not the suburbs, not the resorts, but the city core.

480 — East Valley (Scottsdale, Tempe, Mesa)

Area code 480 is the East Valley’s code, covering some of the fastest-growing and wealthiest municipalities in the American Southwest.

Key 480 cities and districts:

• Scottsdale — Old Town entertainment district, North Scottsdale resort corridor, tech startup scene
• Tempe — Arizona State University, Mill Avenue, Tempe Town Lake
• Mesa — third-largest city in Arizona, Phoenix-Mesa Gateway Airport
• Chandler — Intel campus, semiconductor manufacturing corridor
• Gilbert — one of the fastest-growing towns in the US
• Paradise Valley — high-net-worth enclave between Phoenix and Scottsdale

The 480 code is synonymous with Scottsdale’s identity as a tech and lifestyle hub.

623 — West Valley (Glendale, Peoria, Surprise)

Area code 623 covers the West Valley — a sprawling region of established suburbs, retirement communities, and newer master-planned cities.

Key 623 cities:

• Glendale — State Farm Stadium (Arizona Cardinals), Desert Diamond Arena (Arizona Coyotes)
• Peoria — spring training home of the San Diego Padres and Seattle Mariners
• Surprise — one of Arizona’s fastest-growing cities; major retail and healthcare hub
• Sun City / Sun City West — the original Del Webb retirement communities
• Avondale and Goodyear — NASCAR Phoenix Raceway, growing industrial corridor
• Buckeye — among the fastest-growing US cities by percentage

The 623 code is associated with the West Valley’s mix of active retirement, sports venues, and suburban expansion.

928 — the rest of Arizona

Area code 928 is not a Phoenix code, but it deserves mention for context. It covers all of Arizona outside the Phoenix metro and the Tucson area: Flagstaff, Prescott, Yuma, Lake Havasu City, Bullhead City, Kingman, Show Low, and the Navajo and Hopi Nations.

A 928 call from someone claiming to be a Phoenix business is worth a second look — genuine Phoenix businesses use 602, 480, or 623.

History of Phoenix area codes

Phoenix’s area code history tracks the city’s explosive growth from regional hub to one of the five largest metro areas in the United States.

1947 — 602 covers all of Arizona. When AT&T engineers created the North American Numbering Plan (NANP), Arizona received a single code: 602. It was one of the original 86 NPAs assigned nationwide. At the time, a single code covered the entire state — from the Grand Canyon to the Mexican border — with capacity to spare.

March 19, 1995 — 520 splits off rural and southern AZ. Population growth and the telecom explosion (fax machines, pagers, early internet) began filling 602’s number pool. The Arizona Corporation Commission (ACC) approved relief: area code 520 was assigned to Tucson and all of Arizona outside the Phoenix metro, leaving 602 to cover Phoenix.

March 1, 1999 — the three-way split: 480 and 623 are born. Phoenix’s growth continued at a pace that made another split necessary. Despite only 3 million of 7.5 million available 602 numbers having been issued, the flood of new devices made forward planning essential. The ACC and NANPA approved a three-way division:

• 480 took the East Valley and portions of north Phoenix (Scottsdale, Tempe, Mesa, Chandler, Gilbert)
• 623 took the West Valley (Glendale, Peoria, Surprise, Sun City)
• 602 retained central Phoenix

2001 — 928 splits from 520. Tucson’s 520 code grew tight, and the rural rest of Arizona needed its own identity. Area code 928 was assigned to all of Arizona outside the Phoenix and Tucson metro areas.

September 12, 2023 — boundary elimination overlay. After rapid growth continued filling all three codes, the ACC approved a boundary elimination overlay. As of September 2023, the geographic lines between 602, 480, and 623 were removed. All three codes now serve the same combined Phoenix metro territory. Ten-digit dialing became mandatory one month earlier (August 12, 2023). Existing numbers were unchanged; new assignments can draw from any of the three codes.

NANPA (nationalnanpa.com) serves as the administrator of the North American Numbering Plan. The Arizona Corporation Commission (ACC) functions as the state regulatory body that approves all area code relief strategies in Arizona.

602 vs 480: the Phoenix prestige split

No discussion of Phoenix area codes is complete without the 602/480 cultural divide.

602 is Phoenix’s original code. It carries the weight of history — the first businesses, the first hospitals, the first government offices in Arizona all had 602 numbers. Major Phoenix institutions that predate 1999 still hold 602 numbers: Banner Health’s flagship hospital, Honeywell Aerospace’s Phoenix campus, American Express’s Phoenix operations center.

A 602 number signals downtown Phoenix, established business, and local roots. For professional services firms, healthcare providers, and financial institutions serving central Phoenix, 602 carries authority that 480 does not — in the same way that New York’s 212 outranks 646.

480 is Scottsdale and the East Valley. It carries a different kind of prestige — one associated with tech, wealth, and the resort economy. GoDaddy has its operational headquarters in Scottsdale (480). Insight Enterprises is based in Chandler (480). Carvana is headquartered in Tempe (480). The North Scottsdale resort and luxury real estate corridor runs on 480 numbers.

For a business targeting East Valley clients, a Scottsdale startup, or the tech and hospitality corridor north of Scottsdale Road, 480 signals precisely the right geography.

623 is the West Valley. It does not carry the prestige weight of 602 or 480 but is strongly associated with Arizona’s sports infrastructure, retirement communities, and the newer growth cities west of Phoenix. Republic Services is headquartered in Phoenix but operates extensively across the 623 West Valley corridor.

The 2023 overlay means new numbers can be assigned from any code. But existing numbers — and the cultural cache they carry — remain exactly where they were.

Phoenix area code spam and scams

Phoenix and its surrounding area codes are frequent targets for spoofed scam calls. Several patterns are specific to the Arizona market:

Border and immigration scams (602/623): Callers spoofing Phoenix area codes — particularly 602 — claim to be from ICE, CBP, or the Department of Homeland Security. They threaten deportation or arrest over immigration paperwork errors unless an immediate payment is made. Arizona’s proximity to the US-Mexico border makes this scam particularly effective at triggering fear in immigrant communities.

Fake monsoon and storm repair scams (602/480/623): Arizona’s summer monsoon season (July–September) brings intense storms, flash floods, and roof damage. Scammers spoofing local 480 and 623 numbers pose as licensed roofing contractors offering emergency repairs. They collect upfront payments and disappear. Legitimate contractors in Arizona are licensed with the Arizona Registrar of Contractors (ROC).

Snowbird seasonal residence scams (480): Scottsdale and the East Valley attract tens of thousands of seasonal residents (“snowbirds”) from northern states from October to April. Scammers spoofing 480 numbers target snowbirds with calls about utility disconnection, HOA violations at their Scottsdale properties, or vehicle registration issues — creating urgency tied to an address the victim actually owns.

These scams exploit local caller ID recognition. STIR/SHAKEN (Secure Telephone Identity Revisited / Signature-based Handling of Asserted information using toKENs) is the FCC-mandated caller authentication framework that combats spoofing.

Carriers authenticate outbound calls and assign attestation levels — A (fully verified), B (partial), or C (gateway/unverified). Spoofed scam calls typically receive C-attestation or fail authentication entirely, triggering “Spam Likely” on modern smartphones.

When you get a Phoenix business number through DialPhone, outbound calls carry STIR/SHAKEN A-attestation — the highest trust level — so your 602, 480, or 623 calls reach customers as verified, not flagged.

See the FCC’s guidance on caller ID spoofing: fcc.gov/consumers/guides/spoofing-and-caller-id.

How to get a Phoenix business phone number

Getting a Phoenix 602, 480, or 623 number for your business takes under 10 minutes through a cloud VoIP provider. No Phoenix office required.

Step 1: Choose your area code. Decide whether 602 (central Phoenix authority), 480 (East Valley / Scottsdale identity), or 623 (West Valley) fits your target market. 602 inventory is more limited — check availability first.

Step 2: Sign up with a cloud phone provider. DialPhone lets you search available Phoenix numbers by area code during signup.

Step 3: Assign the number to users or a team queue. Route the Phoenix number to your mobile app, desktop app, or a shared call queue. Set up voicemail, auto-attendant, or an AI receptionist for after-hours coverage.

Step 4: Configure outbound caller ID. Set your Phoenix number as the outbound caller ID so calls you make display the local number — not a toll-free number or personal cell.

Step 5: Port existing Phoenix numbers if needed. If you already have a 602, 480, or 623 number with another carrier, bring it to DialPhone through number porting. US local number porting typically takes 2–7 business days.

Phoenix area code FAQ

Phoenix area code FAQ

What is the area code for Phoenix? +

Phoenix proper uses area code 602, which covers central and downtown Phoenix. The broader Phoenix metro adds 480 (East Valley — Scottsdale, Tempe, Mesa, Chandler, Gilbert) and 623 (West Valley — Glendale, Peoria, Surprise, Sun City).

Since September 2023, all three codes operate as a single overlay — new numbers can be assigned from any of the three codes across the entire metro area.

Is 602 or 480 the Phoenix area code? +

Both are Phoenix metro area codes, but they cover different regions. Area code 602 is the original Phoenix code, established in 1947, and today covers central and downtown Phoenix. Area code 480 was created in 1999 and covers the East Valley suburbs — Scottsdale, Tempe, Mesa, Chandler, and Gilbert.

If someone gives you a 602 number they're likely in central Phoenix. A 480 number typically means East Valley or Scottsdale.

What area code is Scottsdale, AZ? +

Scottsdale uses area code 480. The 480 code was created in 1999 specifically to serve the fast-growing East Valley, which includes Scottsdale, Tempe, Mesa, Chandler, and Gilbert. Scottsdale's tech corridor, Old Town, and North Scottsdale resort district all carry 480 numbers.

Since the 2023 overlay, new Scottsdale numbers may technically be assigned from any of the three Phoenix codes (602, 480, 623), but 480 remains the dominant and most recognized Scottsdale code.

What area code is Glendale, AZ? +

Glendale primarily uses area code 623, which covers the West Valley. Area code 623 was created in 1999 alongside 480 to handle the western suburbs — Glendale, Peoria, Surprise, Sun City, and Avondale. A small sliver of Glendale near the city of Phoenix may carry 602 numbers from the original split boundaries.

What is area code 928? +

Area code 928 covers the rest of Arizona outside the Phoenix metro and Tucson. It includes cities like Flagstaff, Yuma, Prescott, Lake Havasu City, Bullhead City, and the White Mountains region. Area code 928 was created in 2001 when it split from the 520 Tucson code.

If you get a 928 call, the caller is almost certainly from rural or northern Arizona, not from Phoenix or Tucson.

Are Phoenix area code calls spam? +

Not inherently. Legitimate Phoenix businesses use 602, 480, and 623 numbers every day. The problem is spoofing — scammers fake a local Phoenix caller ID to increase answer rates.

Legitimate carriers implement STIR/SHAKEN authentication. DialPhone Phoenix numbers carry A-attestation — the highest STIR/SHAKEN trust level — so your calls display as verified rather than 'Spam Likely.' If you receive an unexpected Phoenix-area call threatening legal action, IRS arrest, or storm repair, treat it as a likely scam.

Can I get a Phoenix 602 or 480 number without a Phoenix office? +

Yes. Virtual VoIP numbers are not tied to a physical address. A business anywhere in the US can get a Phoenix 602, 480, or 623 number through a cloud phone provider and route calls to any device — mobile, desktop app, or team queue.

DialPhone assigns available Phoenix numbers in minutes with no local office, no hardware, and no long-term contract required.

What happened with the Phoenix area code overlay in 2023? +

On September 12, 2023, the Arizona Corporation Commission's approved boundary elimination took effect. The geographic lines separating 602, 480, and 623 were removed. All three codes now serve the same combined metro area.

The practical impact: 10-digit dialing became mandatory for all local Phoenix calls on August 12, 2023 (one month before the overlay). New phone lines can be assigned any of the three codes regardless of location. Existing numbers and local call rates were unchanged.
