Historical Timeline of Area Code 417

In 1950, southwestern Missouri received its own area code when 417 was created as the state's third NPA, split from the original 816 territory. Covering Springfield, Joplin, Branson, and the Ozark hill country, 417 has remained structurally unchanged for over 75 years. Source: Wikipedia.

Key milestones:

  • 1947: AT&T launched the North American Numbering Plan with 86 area codes. Missouri received two NPAs: 314 (eastern) and 816 (western). Source: Missouri PSC Case TO-95-289
  • 1950: Area code 417 carved from the southern portion of 816, establishing Missouri's third NPA. Source: Wikipedia
  • 1995: Missouri PSC opened Case TO-96-1 for exhaustion planning covering 816, 417, and the new 314. Technical committee established to evaluate split and overlay options. Source: Missouri PSC
  • 1996: 573 activated as a geographic split from 314. Area code 417 remained intact. Source: Wikipedia
  • 1997: 816 split: Kansas City metro retained 816 while outstate Missouri received 660. Area code 417 unaffected. Source: Missouri PSC
  • 1999: 636 created from 314 for outer St. Louis suburbs. Area code 417 unaffected. Source: Wikipedia
  • 2021: FCC Order FCC 20-100 mandated 10-digit dialing for 314, 417, 660, and 816 to accommodate the 988 Suicide Prevention Lifeline. Mandatory 10-digit dialing took effect October 24, 2021, ending 71 years of seven-digit local dialing in 417. Source: NANPA PL-544
  • 2022-2024: Missouri added three overlay codes on other NPAs: 557 on 314 (2022), 975 on 816 (2023), and 235 on 573 (2024). Area code 417 remains the state's only major NPA without an overlay. Source: Missouri PSC

The Missouri PSC projects 417 will reach number exhaustion around Q2 2032, while NANPA's October 2025 analysis projects Q3 2037. The discrepancy reflects ongoing number conservation efforts and updated utilization data. Source: Missouri PSC.

Regulatory History

Two major regulatory events have directly affected area code 417: the 1995 Missouri PSC exhaustion planning docket and the 2021 FCC 988 transition order. Both shaped the code's dialing plan and long-term trajectory. Source: Missouri PSC

YearEventDocketRegulatory Action & Impact
1995Exhaustion planning openedCase TO-96-1Missouri PSC opened Case TO-96-1 to address projected exhaustion in 816, 417, and the newly created 314. A technical committee was established with representatives from all industry segments, Staff, and Office of Public Counsel. Report due November 1996. The Commission's decision on 314 exhaustion (Case TO-95-289) ordered a geographic split, not an overlay. (Source: Missouri PSC)
1997Public hearings on 816 splitCase TO-96-1Technical committee recommended geographic split for 816 (retaining KC metro, creating 660 for outstate). Referenced earlier Commission decision on 314/573 split. Area code 417 was assessed but determined not to require immediate relief. (Source: Missouri PSC (Wayback))
2020988 Lifeline designatedFCC 20-100FCC adopted Order FCC 20-100 designating 988 as the National Suicide Prevention Lifeline. Affected area codes with existing 988 NXX codes, including 417, were required to transition to mandatory 10-digit local dialing. (Source: Missouri PSC)
202110-digit dialing transitionCase TO-2021-0155Missouri PSC implemented mandatory 10-digit dialing for 314, 417, 660, and 816. Permissive dialing began April 24, 2021; mandatory October 24, 2021. Seven-digit local dialing permanently eliminated. NANPA distributed planning letter PL-544 to all affected carriers. (Source: NANPA PL-544)

2025Exhaust projection updatedNANPA analysisNANPA's October 2025 exhaust analysis projects Q3 2037 for 417, updated from Missouri PSC's earlier Q2 2032 estimate. The revision reflects ongoing number conservation and carrier coordination efforts across the region. (Source: Missouri PSC)
