What Time Zone Is 737 Area Code in the USA?
The entirety of Area Code 737 falls under the Central Time Zone (CT). This time zone observes Daylight Saving Time (DST) in accordance with national guidelines, resulting in a shift from Central Standard Time (CST) to Central Daylight Time (CDT) in the spring and a return to CST in late autumn.

• Standard Time: Central Standard Time is UTC-6.
• Daylight Saving: When in effect, clocks are set one hour forward to Central Daylight Time (UTC-5).
• Start and End of DST: Typically begins on the second Sunday in March and ends on the first Sunday in November.
History of the 737 Area Code
Area Code 737 was introduced as an overlay to its sister code, 512, to meet the growing demand for new telephone numbers in Central Texas. The official numbering guidelines administered by the North American Numbering Plan Administrator recommended this overlay to maximize number availability.
Timeline
• Year Created: In 2013, Area Code 737 was activated to supplement Area Code 512 and accommodate the increasing population and business expansions in the region.
• Splits and Overlays: Rather than splitting geographically, the state opted for an overlay to minimize disruption, allowing existing numbers in the 512 code to remain unchanged while introducing 737 for new lines.
• Reasons for Changes:
– Rapid population growth in the Austin metropolitan area.
– Technological advancements and increased reliance on mobile and connected devices.
– Expanded economic development, particularly in emerging industries and corporate headquarters.
How Many People Use the 737 Area Code?
Area Code 737 covers a substantial portion of the expanding central Texas population. The region that 737 serves includes some of the fastest-growing cities in the United States. According to the United States Census Bureau data, these areas have experienced a significant population influx over the past decade.
Population Coverage Highlights
• Over 2 million individuals reside in Travis County alone, a large subset of which utilize phone numbers in the 512/737 overlay.
• Neighboring Williamson County and Hays County add significantly to this figure, contributing hundreds of thousands of potential subscribers.
• New business formations and the rise of remote work trends continue to drive the need for phone number expansions.
Is the 737 Area Code Toll-Free?
Area Code 737 is not a toll-free code. It functions as a standard geographic overlay that specifically serves central Texas and its metropolitan areas. When dialing local calls within the 512/737 overlay, subscribers are generally required to use 10-digit dialing (area code + phone number).
Special Rules or Considerations
• Geographic vs. Toll-Free: Unlike toll-free area codes such as 800, 888, or 877, 737 calls incur standard local or long-distance charges, depending on service provider plans.
• Mandatory 10-Digit Dialing: Following the overlay’s implementation, dialing both the area code and the seven-digit number is necessary, even for local calls within city boundaries.
• Regulatory Oversight: Oversight is provided by the FCC communications regulations located at 45 L Street NE, Washington, DC 20554, and the Public Utility Commission of Texas, located at 1701 N. Congress Avenue, Austin, TX 78711.
