History of the 602 Area Code
The 602 area code was created in 1947. Back then, Arizona only had this one code for all phone numbers. This made it simple to call anyone in the state. The code became very important as more people moved to Arizona and more phones were added.
As the population grew, the Arizona numbering plan needed changes. New area codes were added to help manage all the phone numbers. In 1995, the 520 area code was created. It covered all parts of Arizona outside of Phoenix. This made the 602 code only for Phoenix and nearby areas.
In 1999, two more codes were added: 480 for the East Valley and 623 for the West Valley. Phoenix kept 602 in the middle. These splits helped keep phone numbers available as more homes and businesses needed them.
Recently, in 2023, a big change happened. The 602, 480, and 623 area codes were combined into an overlay. This means all three codes now cover Metro Phoenix. Because of this, ten-digit dialing is now required. You always need to dial the area code, even for local calls.
Here is a simple timeline of the 602 area code history:
| Year | Event | Details |
|---|---|---|
| 1947 | 602 created | Only area code in Arizona |
| 1995 | 520 split | Covers Arizona outside Phoenix |
| 1999 | 480 & 623 split | East & West Valley get new codes |
| 2023 | Overlay complex | 602, 480, 623 all cover Metro Phoenix |
The 602 area code has been part of Arizona for over 75 years. It started as the only code and now works with other codes to keep calls simple and organized. Understanding its history helps people know why local dialing rules exist and why Phoenix has this special phone code today.

How 602 Area Code Works
The 602 area code works like a special number system for Arizona. Each phone number has three parts: the area code, the prefix, and the line number. This system is called the Arizona telecommunications numbering plan.
For local calls in Phoenix, you often dial just the number. But because of the 2023 overlay, ten-digit dialing is now needed. This means you always include the area code, even for local calls.
The 602 code works for landlines, mobile phones, and VoIP numbers. Businesses use Phoenix telephony services to manage calls, and people at home use the same code for personal phones.
Here are some safety tips:
- Scams: Some callers pretend to be local to trick people.
- Spoofing: Fake numbers may show 602 to look real.
- Security: Never give personal info on unknown calls.
Even with these risks, 602 is mostly safe. Phone companies and Arizona telecoms have rules to protect customers. Using your number correctly helps everyone connect easily.
