Geographic Coverage & Key Cities

The 972 area code stretches across 11 counties in North Texas, serving a vibrant community of over 7.5 million people when combined with its overlay codes. Established in 1996, the 972 area code was created as a split from the original 214 area code to accommodate the rapid population growth and booming telecommunications demand in the Dallas metropolitan area. This territory covers some of the most dynamic Dallas suburbs, including Plano, Richardson, Garland, Irving, Carrollton, Frisco, Allen, McKinney, Mesquite, and Grand Prairie.

The heart of the 972 area wraps around northern and eastern Dallas County and extends into much of Collin County, forming one of Texas’s most energetic business environments. Richardson, famously known as the "Telecom Corridor," has attracted numerous major technology companies, making specialized answering services for IT firms particularly vital in the area.

Plano has emerged as a corporate hub, hosting the headquarters of global companies, including Toyota North America. The evolution of the 972 area code reflects the region’s rapid economic growth and its role as a hub for technology, corporate business, and suburban development.

Time Zone & Business Impact

Your 972 number is located in the Central Time Zone (CST, UTC-6 / CST, UTC-5), with a daylight saving time shift from March through November. This central location is a business advantage that's often overlooked. Think of it as the Goldilocks zone for national business, not too early, not too late. With just a one-hour difference from Eastern cities and two hours from Pacific ones, you've got substantial overlap with both coasts.

This middle-ground position enables your business to naturally bridge the gap between East and West Coast operations, a subtle yet powerful advantage when coordinating national projects or serving clients across the nation. For best results, schedule East Coast calls between 8:00 AM and 4:00 PM, and West Coast connections between 11:00 AM and 7:00 PM. Goodcall's AI answering service can field calls outside these windows, prioritizing urgent matters during peak hours.
