The 737 area code overlays Austin’s original 512 area code, covering the city and its surrounding metro area. It has become part of Austin’s identity, one of the fastest-growing and most innovative business regions in the country. Known as “Silicon Hills,” Austin attracts startups, tech giants, and entrepreneurs drawn to its skilled workforce and bold energy.
In this environment, a 737 number signals local presence and builds immediate trust with customers who prefer working with businesses rooted in their community. It helps you stand out as part of the local ecosystem, not just another out-of-town caller.
Pair your 737 number with GoodCall’s AI answering service to capture every opportunity. You stay responsive around the clock while maintaining a professional edge, making your number work harder in one of the country’s most competitive markets.
The 737 area code, introduced in 2013, serves as an overlay to Austin’s original 512 area code, covering the same fast-growing region of Central Texas. This area spans seven counties, including Travis, Williamson, Hays, and Bastrop, and includes Austin, Round Rock, Cedar Park, San Marcos, and other thriving communities.
Area code 512 was one of the original area codes established in October 1947, initially covering a large portion of south-central Texas, including Austin, San Antonio, and Corpus Christi. Over time, as the population and telecommunications demand grew, the 512 area code was reduced in size through splits.
Most notably, in 1992, San Antonio and the Rio Grande Valley were assigned area code 210, and in 1999, the southern portion was assigned area code 361. To prevent number exhaustion in the Austin area, the 737 overlay was introduced in July 2013, requiring ten-digit dialing and allowing for continued growth without requiring changes to existing numbers.
The 737 area code operates in the Central Time Zone, which is 6 hours behind UTC during standard time (CST) and 5 hours behind UTC during daylight saving time (CDT). Austin's positioning creates significant advantages for nationwide communication, with just a one-hour difference from East Coast operations and a two-hour gap with West Coast partners, resulting in substantial overlap in business hours between regions.
Financial services markets open at 8:30 AM local time, providing preparation time before trading begins. Austin's Central Time Zone provides tech companies with a strategic edge when working across coasts, as morning meetings align with Silicon Valley's 8 AM start. At the same time, East Coast partners remain within easy reach throughout the afternoon. Pair it with Goodcall's AI answering service for 24/7 coverage that automatically handles time zone differences.
