This high number is primarily due to the state's large size and diverse population. Each area code serves a specific region, with some regions having multiple overlapping codes due to high demand.

When the NANP was introduced in 1947, Texas was assigned four initial area codes: 214 (Dallas), 512 (Austin), 713 (Houston), and 915 (El Paso). These codes were sufficient at the time to cover the state's population and geographical needs. However, as Texas grew, so did the demand for new telephone numbers.
Area codes are a critical component of the North American Numbering Plan (NANP), a system established in the mid-20th century to organize and streamline telephone communication across the United States, Canada, and other participating countries. They are the three-digit prefixes that precede local telephone numbers, helping to identify the geographical location of a caller or recipient.
