The 972 area code introduced in 1996 to relieve the original 214 now shares the Dallas Fort Worth metro with 214, 469, and the newest overlay, 945. The added code keeps fresh numbers available but also cements ten digit (or 1 + ten digit) dialing for every local call. Here’s the need to know rundown.
New 945 Area Code Overlay
Texas regulators chose an overlay layering 945 on top of 972/214/469 rather than splitting the region again. Existing numbers stay the same; only new lines may receive 945 (or one of the other overlays). Because four area codes now serve the same geography, every local call must include the area code plus the seven digit number.
972 / 214 / 469 / 945 Coverage Area
The overlay complex spans nine North Texas counties, including major portions of:
- Dallas, Collin, Denton, Kaufman, Johnson, Navarro, Ellis, Rockwall, and eastern Tarrant
- Cities such as Plano, Frisco, Garland, Irving, Grand Prairie, Arlington, Carrollton, Lewisville, Mesquite, McKinney, Richardson, Allen, and, of course, Dallas itself
Dialing Rules
Landlines: Dial 1 + area code + phone number (11 digits total).
Mobile phones: Dial area code + phone number (10 digits) or 1 + area code + number either works.
Seven digit dialing no longer completes a call.
Ten digit dialing became mandatory on July 1 1999 when 469 joined the overlay.
Key Dates in the 972 Overlay Timeline
| Date | Milestone |
|---|---|
| September 14 1996 | 972 carved from 214 as a geographic split |

| January 15 2021 | 945 numbers begin assignment for new service |
What Stays the Same
- Your current 972 number does not change.
- Local calling areas and pricing remain identical 945, 469, and 214 carry no extra fees.
- Three digit services (911, 211, 311, etc.) still dial with three digits.
- Long distance rules and toll rates remain unchanged.
Frequently Asked Questions
Why add 945 instead of splitting the map again?
Overlays avoid the cost and confusion of forcing residents and businesses to change long standing numbers.
Will caller ID look strange?
No 945 simply shows a newer assignment within the same Dallas Fort Worth footprint.
Do mobile users have to dial “1”?
Most wireless carriers complete calls with either ten or eleven digits; landlines generally need the leading “1.”
Does the overlay raise call charges?
No. Rate center boundaries and tariffs stay exactly the same.
