About 623 Area Code
Area code 623 serves Glendale, Peoria, Surprise, Goodyear and the broader Phoenix West Valley region. Created in March 1999 during a three-way split of the original 602 area code, 623 covers the western portion of metropolitan Phoenix, extending across Maricopa and Yavapai counties. The code supports local voice and SMS-enabled numbers used by sports venues, manufacturing facilities, healthcare providers and retail businesses across one of Arizona's fastest-growing economic corridors.
The 623 region blends semiconductor manufacturing (TSMC, Amkor), advanced logistics (Amazon, distribution centers), professional sports (State Farm Stadium, Desert Diamond Arena), and entertainment districts. Local businesses use 623 numbers for customer service, appointment scheduling, sales outreach and event coordination. Local numbers deliver higher answer rates than toll-free alternatives because they communicate regional presence and community connection to West Valley residents.
FoneSwift shows real-time 623 inventory with Voice, SMS and MMS features on this page. Search available numbers to compare capabilities and formatting options. Availability changes regularly; if your preferred 623 number isn't in stock, nearby codes such as 602 or 480 can still provide strong Phoenix metro recognition for customer-facing operations.
When marketing to the West Valley, display numbers in both local and E.164 formats (e.g., (623) 555-1234 and +1 623 555 1234) for maximum reach. If you're running A2P SMS campaigns, register your messaging traffic with carriers to ensure deliverability. For number porting questions, check our porting guide.

How Does Local 623 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages.

- Country code (+1): identifies United States for international routing.
- Area code (623): directs the call to the Glendale / Arizona region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
