Historical Timeline of Area Code 253

Area code 253 was created on April 27, 1997, as part of a rare three-way split of area code 206 into three NPAs: 206 (Seattle core), 253 (Tacoma and south Puget Sound), and 425 (east side and north). The 253 NPA serves Tacoma, Kent, Federal Way, Auburn, Lakewood, and Puyallup in Washington state. It is projected to receive the 564 overlay when its number supply exhausts around Q3 2053.

Key milestones:

1947: Area code 206 created as one of the original 86 North American area codes, serving all of Washington state (Source: Wikipedia)
1957: 206 split into 206 and 509, with 509 assigned to eastern Washington (Source: Wikipedia)
1995: 206 split into 206 and 360, with 360 assigned to western Washington outside the Seattle metro (Source: Wikipedia)
1997: 253 created via three-way split of 206 on April 27, 1997. Assigned to Tacoma and the south Puget Sound region. Permissive dialing period ended November 16, 1997 (Source: Wikipedia)
2000: Washington Utilities and Transportation Commission (UTC) approved the 564 all-services overlay for 206, 253, 425, and 360 under Docket UT-991535. Permissive 10-digit dialing began September 1, 2000 (Source: UTC Docket UT-991535)
2001: UTC suspended 564 overlay implementation on August 28, 2001, due to successful number conservation efforts (Source: UTC Docket UT-991535)
2016: UTC approved a phased 564 overlay for western Washington under Docket UT-143787 on May 19, 2016 (Source: UTC Docket UT-143787)
2017: 564 overlay activated for the 360 NPA. Mandatory 10-digit local dialing implemented throughout western Washington (Source: UTC 564 Overlay)
2023: UTC approved expansion of the 564 overlay to the 206 NPA under Docket UT-230108 on June 15, 2023 (Source: UTC Docket UT-230108)
2025: 564 overlay placed in service for the 206 NPA on June 10, 2025. The 253 NPA is projected to exhaust in Q3 2053 (Source: UTC Docket UT-230108)

The creation of 253 reflected rapid population growth in the Puget Sound region during the 1990s. Washington state's numbering plan has been managed by the UTC, which has overseen multiple overlay and split events to address number exhaustion across western Washington. The 564 overlay follows a phased activation approach, activating for each NPA as it exhausts rather than simultaneously across all regions.

Regulatory History

Area code 253 has been the subject of three major UTC regulatory dockets and two NANPA planning letters. The regulatory history follows an approve-suspend-re-approve arc spanning 25 years, reflecting the tension between number conservation and overlay planning. Source: UTC Washington State Area Codes
