The 417 area code is southwest Missouri — Springfield, Joplin, Branson and the surrounding Ozarks — and it has covered that territory alone since January 1, 1950, never split, never overlaid, never redrawn. Neither of the state’s 1947 originals can claim that stillness: both gave up land in the 1990s, and both now share their maps with a second code.
A 417 ringing in cold sounds like hometown business — a contractor’s quote, a clinic confirming an appointment — but a hometown display is easy to fake, so the code vouches for nobody.
417 at a glance
| Quick fact | Answer |
|---|---|
| In service since | January 1, 1950 |
| Split from | 816 |
| Overlay | None — never split, never overlaid |
| Territory anchors | Springfield, Joplin, Branson, Nixa, Lebanon |
| Dialing | Ten digits, mandatory since October 24, 2021 |
| Exhaust projection | Second quarter of 2032 (NANPA, April 2026) |
The stillness is the story. Between August 2022 and March 2024, Missouri switched on three overlay codes in quick succession, and none came anywhere near the southwest. What 417 has instead is the nearest exhaust projection in the state — a date that has jumped six years between studies — and, so far, not one line of relief paperwork behind it.
Three state lines and the Ozark plateau
The code fills Missouri’s southwest quarter. Springfield, the state’s third-largest city, anchors it with a suburban ring of Nixa, Ozark and Republic; Joplin, Carthage, Webb City and Neosho hold the western edge where Kansas and Oklahoma begin; Branson and Hollister work the theater-and-lake country above the Arkansas line; Lebanon, Bolivar and West Plains fill in the plateau between. Every corner of it keeps Central Time.
Inside Missouri, the neighbors are 816 and 660 to the north and 573 to the east — the arrangement the state’s utility commission drew on its consumer dialing map. Cross the line southwest of Joplin and you are in 918 country, Tulsa’s code since 1953.
Where 816 ended and 417 began
Missouri entered the numbering plan in 1947 holding two codes: 314 for the St. Louis side and 816 for Kansas City’s, both in service January 1 of that year by NANPA’s records. Three years later the southwest got its own. NANPA’s database logs 417 assigned and in service on January 1, 1950 — a New Year’s Day launch that lifted the Ozarks out of the Kansas City code’s territory.
That three-code map held for forty-six years, until 573 went live on January 7, 1996; 660 followed in October 1997 and 636 in May 1999. Every one of those changes happened around the southwest, never to it. NANPA’s database records no code ever carved out of 417 — the 1950 boundary is still the boundary.
Why doesn’t the 417 area code have an overlay?
Because it has never come close to needing one. NANPA’s database lists 417 with no overlay and no second code assigned to its territory, and the only planning letters on its record are the two that governed 988 dialing — nothing about relief, jeopardy or rationing has ever carried its name.
The rest of Missouri went the other way. 557 opened over St. Louis’s 314 on August 12, 2022; 975 over Kansas City’s 816 on October 13, 2023; 235 over mid-Missouri’s 573 on March 24, 2024. Three overlays in twenty months, none of them anywhere in the southwest.
That last code causes confusion worth clearing up. Secondhand write-ups sometimes attach 235 to the Ozarks, but NANPA assigned it on May 2, 2022 as relief for 573, and it has served the 235/573 territory — mid-Missouri, not the southwest — since March 24, 2024. As of NANPA’s August 14, 2026 database, 417 has no overlay in service, none scheduled and none proposed.
The dialing rule 988 rewrote
Seven-digit local calls worked in 417 for seventy-one years, and it took a crisis hotline to end them. Once the FCC designated 988 as the suicide-and-crisis line’s number, every code that both allowed seven-digit dialing and had 988 working as a prefix had to convert. NANPA’s Planning Letter PL-556 of January 8, 2021 — superseding PL-544 — settled that list at 82 codes, four of them Missouri’s: 314, 417, 660 and 816.
Ten-digit local dialing became mandatory on October 24, 2021, carriers completed enforcement by July 15, 2022, and 988 went live nationwide the following day. The state’s consumer notice drew the boundary plainly: 573 and 636 were not affected. Today NANPA lists 417 local calls at ten digits and toll calls at 1 plus ten — and 636, west of St. Louis, remains Missouri’s last seven-digit holdout.
From 2037 to 2031 to 2032
NANPA’s April 2026 NPA Exhaust Analysis — the 2026-1 study, built on utilization reported through March 1 — projects 417’s assignable prefixes lasting into the second quarter of 2032. That is five quarters more than the October 2025 study allowed, a revision NANPA files under reduced historical and projected demand.
The date has been restless. The April 2025 study said third quarter of 2037; six months later the forecast surrendered twenty-six quarters; six months after that it clawed five back. Projections track carrier demand filings, and in a one-code market a few revised filings can move the horizon by years — the prefix arithmetic underneath is worth understanding before reading much into any single date.
Even the near reading starts no machinery. NANPA’s relief-activity and trigger reports, both current to August 14, 2026, carry no 417 entry, and the four forecasts NANPA revised on July 6, 2026 all sat in Texas. Still, 2Q 2032 is the earliest projected date in Missouri — the other five code territories run from late 2060 out past 2100 — so the state’s next relief conversation points squarely at the Ozarks.
Whenever that conversation opens, it will be the first in the code’s seventy-six years. The modern playbook — traced in our guide to how area codes work — favors overlays, and under an overlay existing numbers keep every digit they have.
The code that became the region’s nickname
Southwest Missouri may be the only market where the area code doubles as the region’s name in print. Locals shorthand the Springfield–Branson–Joplin corridor as 417-land, and the glossy that covers its restaurants and lake houses is titled, simply, 417 Magazine. Seventy-six years under one set of digits will do that to a place.
That identity has cash value on caller ID. For a contractor quoting roofs in Nixa or a clinic confirming appointments in Webb City, a 417 display reads hometown in a way no out-of-state number can, and the answer-rate case for matching display to market is measurable rather than sentimental.
A hometown display is also easy to fake. Caller ID spoofing can manufacture a 417 display from anywhere on earth, so looking local and being verifiable stay separate properties — and the second one gets established at the carrier, in the signing of the call itself.
That is the part SIPNEX handles directly: an FCC-licensed carrier — direct authorization, not resale — provisioning local DID numbers against the exact rate centers you name, southwest Missouri exchanges included where stock permits, delivered over SIP trunking to any PBX or dialer. Outbound calls go out the door signed at A-level attestation under SIPNEX’s own STIR/SHAKEN certificate, and toll-free coverage runs on SIPNEX’s RespOrg registration for campaigns that carry an 800-family line.
Fielding the common 417 questions
Is Branson in the 417 area code?
Yes. Branson, Hollister and the Table Rock Lake country all dial 417, the same code the rest of southwest Missouri has used since 1950. The roster runs from Springfield and its ring — Nixa, Ozark, Republic — west to Joplin, Carthage and Neosho, and across the plateau to Lebanon, Bolivar and West Plains.
Is the 235 area code an overlay of 417?
No. NANPA assigned 235 as relief for mid-Missouri’s 573, and it has served that code’s territory — not the southwest — since March 24, 2024. 417 carries no overlay in service or on any schedule; every number issued in the region still begins with the same three digits it has carried since 1950.
When did the 417 area code go to ten-digit dialing?
October 24, 2021 — the mandatory date NANPA’s PL-556 set for every code where 988 doubled as a working prefix, with carrier enforcement finished by July 15, 2022. Missouri placed four codes on the 82-code list: 314, 417, 660 and 816. The conversion cleared the way for the 988 crisis line’s July 16, 2022 launch; toll calls in 417 dial 1 plus ten digits.
What happens when the 417 area code fills up?
Not before the second quarter of 2032, on NANPA’s April 2026 projection — and no relief work exists yet: no docket, no jeopardy declaration, no rationing. As the date closes in, Missouri regulators will pick a relief method, overlays being the modern default, and existing 417 numbers would keep every digit. Only brand-new numbers would arrive under a second code.
Do I need a Springfield address to get a 417 number?
No. Numbers belong to rate centers rather than street addresses, and SIP delivery rings them anywhere — an office in another state can answer a Springfield or Joplin number the moment it is provisioned. Availability turns on each rate center’s inventory on the day you order; SIPNEX stocks local DIDs in markets across the US and lands them on the phone system you already run.
One code has meant the Ozarks for seventy-six years, and no second one is coming anytime soon. SIPNEX puts those digits on your outbound calls under its own FCC license, signs every leg at A-level attestation, and keeps its rates posted — reach the team through the contact page or at (833) 665-2220.
