The 480 area code serves the East Valley of metropolitan Phoenix, including the cities of Mesa, Scottsdale, Tempe, Chandler, and Gilbert. Created in 1999 when it split from 602, 480 covers some of the fastest-growing and most economically dynamic suburbs in Arizona.
Quick Summary of the 480 Area Code
| Area Code | 480 |
| State | Arizona (AZ) |
| Region | East Valley (Scottsdale, Mesa, Tempe & Chandler) |
| Major Cities | Mesa, Scottsdale, Tempe, Chandler, Gilbert, Apache Junction, Fountain Hills |
| Time Zone | Mountain Standard Time (MST) – no daylight saving |
| Dialing Format | 7 or 10-digit dialing |
Geographic Coverage
The 480 area code covers the eastern side of the Phoenix metro, including Mesa – one of the largest cities in the country – the resort city of Scottsdale, the university city of Tempe, the technology hub of Chandler, and the fast-growing town of Gilbert, along with Apache Junction and Fountain Hills on the eastern fringe. It sits east of the 602 Phoenix core.
Time Zone
The 480 area code observes Mountain Standard Time (MST, UTC−7), but Arizona is unusual: it does not observe daylight saving time and keeps the same clock all year. This produces an interesting effect – in winter the region is on Mountain Time, one hour ahead of the West Coast, but in summer, when other states spring forward and Arizona does not, the 480 area effectively matches Pacific Daylight Time and shares the same clock as California.
Tip: Business hours across the 480 region generally run 9:00 AM to 5:00 PM local time, Monday through Friday.
How to Dial a 480 Number
Area code 480 is not part of an overlay, so it has traditionally allowed 7-digit local dialing. However, 10-digit dialing is now the recommended nationwide standard, and dialing the full 10-digit number (480 + the line number) always works reliably. For international callers, dial your country’s exit code, then +1 (the North American country code), then 480, followed by the seven-digit local number.
Scam Alerts for the 480 Area Code
Like every U.S. area code, 480 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Mesa, Scottsdale, Tempe, Chandler, Gilbert, Apache Junction, Fountain Hills should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Threatening calls demanding immediate tax payment via gift cards or wire transfer. |
| Utility Shut-off | Impostors claiming to be SRP or APS threatening to cut power in the summer heat. |
| Tech Support Fraud | Pop-ups or calls claiming your computer is infected and asking for remote access. |
| Student Loan Scam | Calls offering fake loan forgiveness to Arizona State University students for a fee. |
If you receive a suspicious call from a 480 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the Arizona Attorney General’s Office.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (APS, SRP, or Tucson Electric Power) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 480 caller making such a demand is a scammer.
