Area codes 214, 469, 972, and 945

{{short description|Area codes for Dallas, Texas, United States}} {{Use American English|date=May 2025}} {{Texas area codes image map|214/469/972/945}} {{coord|32|46|45|N|96|48|32|W|type:city_region:US-TX|display=title}} '''Area codes 214, 469, 972, and 945''' are telephone [[area code]]s in the [[North American Numbering Plan]] (NANP) for [[Dallas|Dallas, Texas]], and most of the eastern portion of the [[Dallas–Fort Worth metroplex]]. The area codes are assigned in an [[overlay complex]] to a single numbering plan area that was the core of one of the original area codes of 1947, area code 214.

==History== The original configuration of the [[Original North American area codes|first nationwide]] [[telephone numbering plan]] in 1947 divided the state of Texas into four numbering plan areas (NPAs) with area codes 214 (north-east), [[area code 512|512]] (south-central), [[area code 713|713]] (south-east), and [[area code 915|915]] (north-west and west), respectively.

Numbering plan area 214 extended roughly from a line just west of [[Dallas]] to [[Waco, Texas|Waco]], to the borders of [[Arkansas]] and [[Louisiana]].

In 1954, most of [[Tarrant County]] was combined with much of the eastern region of area code 915 to form [[area code 817]].

Despite the growth of the Dallas metropolitan area in the second half of the 20th century, this configuration remained in place for thirty six years. In 1990, the entire eastern portion of the 214 area was split off with [[area code 903]].

The 1990 split was intended as a long-term solution, but within five years 214 was close to exhaustion due to the rapid growth of the Metroplex as well as the popularity of cell phones, fax machines and pagers. As a remedy, all of the old 214 territory outside Dallas and Dallas County was split off with area code 972 in 1996. Within only two years, however, both 214 and 972 were on the verge of exhaustion again. Area code 469 was introduced on July 1, 1999, in an [[overlay plan]] for most of the eastern portion of the Metroplex. At the same time, the 214/972 boundary was "erased," and 972 was converted into an additional overlay for the entire region. The result was three area codes overlaying the same area, with [[ten-digit dialing]] required for all calls.

Since 2000, 214 and 972 have served as overlays for portions of eastern Tarrant County ([[Arlington, Texas|Arlington]], [[Bedford, Texas|Bedford]], [[Euless, Texas|Euless]], [[Grapevine, Texas|Grapevine]], [[Southlake, Texas|Southlake]], and [[Colleyville, Texas|Colleyville]]) which are closer to Dallas.

While this had the effect of allocating over 23 million numbers to an area of just over nine million people, under 2018 projections, the Dallas area would need a fourth area code by mid-2021.<ref>{{cite web |title=2018-2 NRUF and NPA Exhaust Analysis |url=https://nationalnanpa.com/reports/2019-2_NPA_Exhaust_Projections_Final.pdf |publisher=[[NANPA]] |access-date=2020-02-02 |archive-date=2020-02-21 |archive-url=https://web.archive.org/web/20200221214515/https://nationalnanpa.com/reports/2019-2_NPA_Exhaust_Projections_Final.pdf |url-status=dead }}</ref> Area code 945 was selected as the fourth area code in the Dallas overlay, after receiving approval from the [[Public Utility Commission of Texas]].<ref>{{cite web |title=The new 945 Area Code is Coming to the Texas 214/469/972 Area Codes Region |access-date=2020-12-15 |publisher=[[T-Mobile US]] |url=https://www.t-mobile.com/coverage/tx-area-code-overlay-sms }}</ref> Central office code assignments for NPA 945 have been available since January 15, 2021,<ref>{{Cite web |title=Planning Letter 537: NPA 214/469/972 and 945 All-Services Overlay (Texas) |url=https://www.nanpa.com/sites/default/files/planning_letters/PL-537.pdf |date=2020-04-08 |access-date=2025-05-02 |publisher=[[NANPA]] }}</ref> but can only be requested after all existing area codes are exhausted.<ref>{{cite web|title=Dallas–Fort Worth is getting a new area code because its population is growing so much|date=2020-03-03 |url=https://www.wfaa.com/article/news/local/new-area-code-approved-for-dallas-area-to-accommodate-population-growth/287-aad4e65c-9650-4ed1-8840-8399f12dedcf|publisher=[[WFAA]]|access-date=2020-12-15}}</ref> Projections of 2023 suggested that a fifth area code is not needed until around 2032.<ref>{{Cite web |date=2023-10-01 |title=2023-2 NRUF and NPA Exhaust Analysis |url=https://nationalnanpa.com/reports/2023-2NPAExhaustProjectionsFinal.pdf |url-status=live |archive-url=https://web.archive.org/web/20240202063627/https://nationalnanpa.com/reports/2023-2NPAExhaustProjectionsFinal.pdf |archive-date=2024-02-02 |website=NANPA}}</ref>
