Historical Timeline of Area Code 220

Area code 220 was activated on April 22, 2015, as an all-services overlay on area code 740. It traces its lineage to area code 614, one of the original 86 area codes assigned in 1947, which was split in 1997 to create 740 for southeastern and central Ohio. After number exhaustion projections showed 740 would run out, the Public Utilities Commission of Ohio approved the 220 overlay in December 2013, with mandatory 10-digit dialing taking effect March 21, 2015.

Key milestones:

  • 1947: AT&T Bell System assigns 614 to central and southeastern Ohio as one of the original 86 area codes (Source: Wikipedia)
  • 1997: 740 created by geographic split of 614. The 614 retained the Columbus metro; 740 took southeastern and central Ohio. Source: NANPA PL-088
  • 2013: PUCO approved overlay of 220 onto 740 in Case 13-0700-TP-COI, choosing overlay over geographic split after over 900 public comments favored the overlay option. Source: PUCO Press Release
  • 2015: Mandatory 10-digit dialing required across the 740/220 numbering plan area on March 21. Area code 220 went into service on April 22, becoming the 383rd area code in the North American Numbering Plan. Source: PUCO Press Release
  • 2025: NANPA 2025-2 NPA Exhaust Projections placed the combined 220/740 complex exhaust date at Q3 2055 (Source: NANPA cross-reference)

The 614 to 740 split followed a broader pattern of Ohio area code relief. When 740 itself approached exhaustion, PUCO determined that an overlay rather than another geographic split was the most equitable approach.

Regulatory History

The 740/220 area code complex has been shaped by multiple regulatory actions over nearly two decades. NANPA Planning Letter PL-088 authorized the 614 split creating 740 in 1997. In 2013, PUCO Case 13-0700-TP-COI approved the 220 overlay after an industry consensus petition and public comment process. Mandatory 10-digit dialing took effect March 21, 2015, with new 220 numbers assigned starting April 22, 2015. Source: PUCO Press Release
