The area code 972 is located in Carrollton, Texas.
Area code 972 serves Carrollton, Texas, a fast-growing city in the Dallas–Fort Worth metro in North Texas. Centered north of downtown Dallas, Carrollton sits at the crossroads of Dallas, Denton, and Collin counties, making 972 important for both residents and businesses. The code covers a mix of neighborhoods, corporate campuses, and retail hubs along major corridors like I‑35E and the President George Bush Turnpike. It’s a key identifier for local phone numbers across the north side of the metro.
Established in 1996, 972 was introduced as a split from 214 and later became part of an overlay with 214 and 469, which means all three area codes cover the same geography. Today, 972 spans parts of Dallas, Collin, Denton, Rockwall, and Kaufman counties. Major cities and communities using 972 include:
Because 972 is in an overlay complex, 10‑digit dialing is required for local calls, and new numbers in Carrollton may be issued as 972, 214, 469, or (in some cases) 945. This setup helps keep numbers available across the high‑growth Dallas area while letting people keep their existing phone numbers. You’ll see 972 tied to major employers, suburban campuses, and key North Dallas landmarks, including university and business districts in Plano and Richardson. “Ten-digit dialing is mandatory in areas with an overlay.” — Federal Communications Commission (FCC)
