Find any 737- phone number in Texas
The 737 area code is an area code designated for a large swath of Texas, the second most populous state in the United States. Created in 2015 and serving as an overlay for existing 512 and 737 area codes, the 737 area code covers much of the Texas Hill Country, extending to the capital of Austin and its suburbs and many other locations in between. It serves a total of 22 counties, including Travis and Williamson Counties, and covers a population of 4.7 million people.
The 737 area code is designated and maintained by the North American Numbering Plan, spread out across the United States, Canada, and 24 Caribbean nations. This plan focuses on assigning each location in the region a specific three-digit area code, which is then broken down into smaller and more specific region-specific seven-digit local phone numbers.
The purpose of the North American Numbering Plan is to streamline communications and keep phone numbers in each region within small and manageable blocks. Such plans enable efficient phone numbers that are easy to remember and saves money for communication businesses and customers alike.
