Elimination of 214/972 Split Line and Introduction of 469 Overlay for Dallas, Texas

Reminder of July 1, 1999 date for the Introduction of the 469 NPA for Dallas, Texas to overlay existing 214/972 NPAs; Please refer to PL-142

Introduction of NPA 469 and conversion of 972 to overlay in Dallas region

On July 1, 1999, area code 469 was introduced as an overlay for most of the eastern Dallas–Fort Worth metroplex. At the same time, the boundary between 214 and 972 was removed, converting 972 into an overlay for the entire region. This created a three-code overlay complex requiring ten-digit dialing.

Ten-digit dialing became required across the 214/469/972 region

With the 469 introduction and 214/972 boundary erasure, ten-digit dialing became required for all calls in the region.
