# The 832 Area Code

The 832 area code is an overlay to the 713 area code, serving the Greater Houston metropolitan area in Texas. It was established in 2000 to meet the growing demand for telephone numbers as Houston's population and business sectors expanded rapidly. The 832 area code covers the same geographic territory as 713, including Houston and surrounding communities, meaning residents and businesses in this region can have phone numbers with either area code regardless of their specific location. This overlay system allows both area codes to coexist in the same service area, effectively doubling the available phone number capacity without requiring customers to change their established numbers.

The North American Numbering Plan (NANP) is the standardized system that designates area codes like 832 throughout North America, including the United States, Canada, and other territories. The NANP organizes phone numbers into a three-digit area code followed by a seven-digit local number, with the area code identifying the geographic region where a phone line is registered. The system is managed by the North American Numbering Plan Administrator (NANPA), which allocates area codes to regional telephone companies based on population growth and number demand. When an existing area code becomes depletedas happened with 713overlay area codes like 832 are introduced as a solution that preserves existing numbers while providing the capacity needed to serve growing communities.
