Introduction
Kansas City was supposed to get a second area code in 2002. It didn't happen for twenty-one more years. Regulators had already approved 975 as an overlay in 2001, then shelved it once conservation measures bought the region two more decades on its 816 numbers. That kind of delay is rare, and it explains the confusion still surrounding a code that only went live in October 2023.
975 is the newer of two area codes now serving the same stretch of northwestern Missouri, layered on top of 816 rather than replacing any part of it. Every existing 816 number stayed as it was, and new lines started drawing from the 975 block once the overlay activated. Fourteen counties around Kansas City and St. Joseph sit inside its boundary, and all of them share one dialing rule now. What follows covers why the launch took so long, where the boundary sits, and how to get a 975 number regardless of where you're calling from.
What Is the 975 Area Code?
975 is a geographic area code under the North American Numbering Plan, assigned to the Missouri side of the Kansas City metro area along with St. Joseph and the surrounding region. It isn't a standalone territory: it's an overlay, sharing the exact footprint of 816 rather than carving out its own piece of the map.
NANPA and the Missouri Public Service Commission activated the overlay on October 13, 2023, making 975 the 460th area code put into service nationwide. The trigger was a 2021 exhaust analysis projecting 816's central office codes would run out by 2023. Rather than splitting the region and forcing customers onto a new code, an overlay let Kansas City keep every existing 816 number untouched.
Why Did This Area Code Take Twenty Years to Launch?
The 975 overlay isn't actually new. NANPA approved it on February 20, 2001, with service planned for that October, then pushed to May 2002. Before that date arrived, number-pooling and other conservation measures worked well enough that the Missouri PSC suspended the plan, and Kansas City carried on with 816 alone for another twenty-one years.
What finally forced the issue wasn't population growth alone. In 2020, 988 became the nationwide three-digit code for the Suicide & Crisis Lifeline, conflicting with existing 816 numbers on that exchange. That conflict pushed the region into mandatory 10-digit dialing by October 24, 2021, two years before 975 went live. A fresh NANPA exhaust analysis that year confirmed 816 was running out of room, and the shelved 2001 plan was revived and activated in 2023.
Where Is the 975 Area Code Located?
975 covers the Missouri side of the Kansas City metro area, the city of St. Joseph, and the rural counties around them. It doesn't reach across the state line into Kansas, a mix-up that trips up even some virtual number providers.
Cities and Counties in the 975 Region
Regulatory notices name Kansas City, Blue Springs, Independence, Grandview, Belton, Lee's Summit, Kearney, and Peculiar, alongside St. Joseph, Richmond, Odessa, Harrisonville, and Adrian. The overlay spans counties including Jackson, Clay, Platte, Cass, Ray, Clinton, Buchanan, Caldwell, Bates, Lafayette, Saline, Andrew, and DeKalb.
Bordering Area Codes
975 and 816 border 660 on the north, east, and south, and Kansas's 785 and 913 to the west. None overlap 975's territory, so a business targeting Kansas City has no reason to look at them instead.
975 vs. 816: What Actually Changes
The practical gap between the two codes is smaller than the backstory suggests. The table below sets out what changes and what stays the same. The same overlay pattern appears in Oakland, where the 341 area code stacks alongside 510 under identical rules.
| Aspect | 816 (original) | 975 (overlay) |
|---|---|---|
| Coverage area | Kansas City metro & St. Joseph | Identical to 816 |
| First issued | 1947 | October 13, 2023 |
| Assigned to | Existing lines, unchanged | New lines after October 2023 |
| Dialing format | 10-digit | 10-digit |
| Local call cost | Unaffected | Unaffected |
| Customer can request it? | Yes, if capacity allows | Assigned automatically |
Cost is the detail that trips people up most: neither code changes what a call costs or whether it counts as long distance. A call local before October 2023 stays local today, regardless of which code either side dials from.
How Do You Dial a 975 or 816 Number?
Every call in the region, local or not, needs the full area code and seven-digit number, no exceptions, no shortcuts back to the old seven-digit habit. That rule predates 975 itself: it arrived in October 2021, once 988 needed to work as a three-digit code without colliding with existing 816 exchanges.
That sequencing is unusual. Most overlay regions roll out mandatory 10-digit dialing at the same moment the new area code activates, with a permissive dialing window bridging the two. Kansas City skipped that transition, since residents had already been dialing ten digits for two years by the time 975 numbers existed.
What Time Zone Does the 975 Area Code Use?
Every 975 number sits in the Central Time Zone, the same zone covering Chicago, Dallas, and Minneapolis. Standard time runs six hours behind UTC; during daylight saving time, roughly March through November, that narrows to five hours behind.
For a business on either coast, that detail changes when a Kansas City line actually gets answered. A West Coast team keeping Pacific hours is already two hours behind Kansas City's clock, so a 975 line can go unanswered right when a caller expects the workday to start. Building schedules around Central time, not headquarters time, closes that gap.
Do Local Numbers Really Get Answered More Often?
Recipients are measurably more likely to answer a number matching their own region than one that looks unfamiliar or out of state, which is the entire commercial case for a 975 number. New numbers still carry some risk here, since a line with no call history can get flagged as "Scam Likely" regardless of area code.
Carriers address that with STIR/SHAKEN, the caller ID authentication framework that cryptographically signs a call to confirm it hasn't been spoofed — the FCC guide covers how it works in detail. A provider signing at full attestation gives a brand-new 975 number real trust from its first call, rather than leaving it to earn a reputation slowly over months of unflagged activity.
How to Get a 975 Area Code Number
No Kansas City address, business license, or Missouri residency is required to activate a 975 number. Individuals and companies with no presence in Missouri can provision one through a VoIP or virtual number provider.
Anyone holding an 816 or 975 number elsewhere can typically port it in for free, and most providers let a business run an older number alongside the new one while it ramps up. None of this needs a Missouri mailing address — a properly built system routes a Kansas City number through real wholesale VoIP infrastructure to a laptop, mobile app, or desk phone anywhere in the world.
Why Businesses Choose a Local 975 Number
A decade ago, a local Kansas City number implied an office near Union Station. Today, a support rep in Manila or a founder three time zones away can activate a 975 line and sound like they're calling from the River Market. That gap between where a business sits and where its number appears is no longer a workaround; for a growing share of buyers, it's simply how the number gets used.
The reasoning holds for any business serving Kansas City customers without a local address. Logistics firms, healthcare practices, and franchises expanding into the metro lean on the same math: a recognizable area code lowers the friction of that first call, whether the person answering sits in Missouri or thousands of miles away.
Conclusion
816 and 975 cover identical Kansas City-area ground, and 975 only exists because 816 ran out of room to issue, not because the region changed. Both codes take all ten digits on every call, both bill the same, and neither is replacing the other. The real story here isn't the overlay, it's the twenty-one years Kansas City spent not needing it. That gap is what makes 975 worth understanding on its own terms.
Getting a 975 number doesn't require living in Missouri, or in the United States at all. Providers such as TKOS route numbers across 100+ countries with a 24/7/365 network operations center behind every line. That kind of infrastructure can issue a 975 line to a business anywhere and have it live within minutes. The area code's history is unusual; the ten-digit habit that keeps it working is not.
