Area codes serving Dallas
Dallas sits in Texas, part of the South region and the Central Time zone. Its numbers are spread across an overlay of 4 codes that all cover the same ground: 214, 469, 945, 972.
The original code is 214 (in service since 1947). As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.

How to pick an area code for a new number
When you activate a new line in Dallas, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 214), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.
