The 945 area code is a telephone area code in the North American Numbering Plan (NANP) that serves parts of North Texas, primarily the Dallas metropolitan area. Introduced as an overlay to the existing 214, 469, and 972 area codes, the 945 area code was created to meet the growing demand for new phone numbers in one of the fastest-growing regions in the United States.

In this guide, you’ll learn about the 945 area code location, the cities it covers, its time zone, and other important facts.

What Is the 945 Area Code?

The 945 area code is an overlay area code that serves the same geographic region as area codes 214, 469, and 972. Because it is an overlay, multiple area codes can exist within the same city or neighborhood.

This means new phone numbers in the region may be assigned the 945 area code without changing existing numbers.
