Historical Timeline of Area Code 380
Area code 380 was activated on February 27, 2016 as an overlay of area code 614 in central Ohio, serving Columbus and surrounding communities. The overlay was first approved by the Public Utilities Commission of Ohio (PUCO) on June 27, 2001 in Case No. 00-1260-TPCOI, but implementation was delayed approximately 15 years because number pooling reduced the projected exhaustion date for 614.

Key milestones:
- 1947: Area code 614 created as one of the original Ohio NPAs, assigned to the southeastern quadrant covering Columbus to the Ohio River. Source: Wikipedia
- 1998: The 740 split removed the southern and rural portion of old 614 territory. Ameritech's proposed plan was substantially modified by consumer action (McFarland v. Ameritech, PUCO 97-547-TP-CSS), the first time nationally an ILEC plan was modified by consumer action. Source: Wikipedia
- June 27, 2001: PUCO approved all-services overlay of 380 for 614 (Case No. 00-1260-TPCOI). Implementation delayed approximately 15 years due to number pooling reducing exhaustion forecasts. Source: PUCO
- January 14, 2015: PUCO ordered implementation of 380 overlay. February 20 — NANPA PL-477 issued. July 24 — Public announcement. August 1 — Permissive 7/10/11-digit dialing begins.
- January 30, 2016: Mandatory 10-digit dialing required in 614/380 area.
- February 27, 2016: Area code 380 enters service as the 386th NPA in the North American Numbering Plan. New numbers may be assigned as either 614 or 380.
The structured 12-month transition from customer education through mandatory dialing ensured minimal disruption for the approximately 2.3 million residents in the 614/380 service area.
