Newest US Area Codes
Which US area codes are newest in 2026? Full table of recently activated overlays (2024–2026), pending codes, and how new codes affect your business number.
Several new US area codes have activated since 2024, all as overlays sharing existing geography.
The most recent activations: 483 (Alabama, February 2026), 471 (Mississippi, January 2026), 679 (Detroit, November 2025), 457 (Louisiana, September 2025), and 564 (Seattle, June 2025). The next scheduled code is 465 for New York City, going live June 18, 2026.
This page tracks every recently activated US overlay, codes in the pipeline, and what a new area code means if your business number is already in one of those regions.

Pending and upcoming area code activations
The following US codes are approved or in advanced planning as of May 2026. Dates are subject to PUC order.

Why are new area codes always overlays now?
Geographic splits — where part of a region gets a new code and affected customers must change their number — were standard through the 1990s. Then the backlash hit.
When area codes split, businesses had to reprint stationery, update websites, retrain staff, and pay for number-change notifications. Customers missed calls from numbers they didn’t recognize as local. Regulators heard it loudly.
By the early 2000s, most state PUCs had shifted to overlays as the default relief method. Under an overlay, the new code is layered over the same geography. Only brand-new subscribers and new lines receive the new code. Existing numbers never change.
The operational trade-off is mandatory ten-digit dialing. In an overlay region you must dial the area code even for local calls — including calls to neighbors with the same original code.
The NANPA and state PUCs still formally evaluate both options for each exhaustion event, but geographic splits have not been approved in the contiguous US since the early 2000s.
For a deeper dive into how NANPA assigns codes, see our guide how are area codes assigned.
Which states are getting new codes most often?
California leads the country. In 2024–2025 alone, it added three new overlays: 738 (Los Angeles), 837 (Redding/northeastern CA), and 357 (Fresno). The state’s dense urban areas and high mobile and IoT device penetration exhaust number pools faster than anywhere else.
Texas comes second. Houston’s 713 received the 621 overlay in January 2025, and Dallas-Fort Worth already carries codes 214, 469, 972, and 945 (the latter activated 2021).
New York is next — after the five-borough 465 overlay activates in June 2026, NYC will have five active area codes: 212, 332, 347, 718, 917, 929, and 465. New York City’s number demand is driven by financial services, media, technology, and the sheer density of mobile users.
Florida and Ohio round out the top five. Jacksonville added 324 in February 2024; northeastern Ohio (Lorain/Ashtabula) added 436 in March 2024.
How a new area code affects existing businesses
If your business already has a number in an affected region — say, a 334 Alabama number or a 662 Mississippi number — a new overlay changes nothing for you.
Your number stays the same. Your callers still reach you the same way. The only change you may need to make: if you haven’t already, you must use ten-digit dialing for all outbound calls in the overlay region (including local calls).
New overlay codes only assign numbers to new subscribers and new lines. Your 334 or 662 number is not reassigned and does not change at any point.
Where businesses do see friction is with brand-new numbers in newly activated codes. When 689 overlaid 407 in Orlando in 2019, some early 689 callers found their calls flagged “Spam Risk” on recipients’ smartphones. The Florida Public Service Commission acknowledged the issue but noted it was outside their jurisdiction — the flagging comes from third-party carrier analytics systems that use “unrecognized area code” as a spam signal.
That normalization window typically runs three to six months as carrier databases update. After that, new-code numbers behave identically to established ones.
See area codes for Orlando and area codes for Dallas for examples of how recently activated codes establish themselves in their markets.
How to get a number in a new area code with DialPhone
DialPhone maintains number inventory across all 313 active US geographic area codes, including the newest overlays activated in 2025 and 2026.
Numbers assigned through DialPhone carry STIR/SHAKEN A-attestation from the moment you start making calls. A-attestation is the highest trust level in the FCC-mandated caller authentication framework — it signals to every receiving carrier that your number is fully verified and belongs to a real, provisioned subscriber.
This matters most for numbers in newly activated overlay codes. The “Spam Risk” problem that hit early 689 (Orlando) adopters in 2019 stemmed from carrier analytics treating unrecognized codes as suspicious. STIR/SHAKEN A-attestation bypasses that heuristic entirely — your call arrives as verified regardless of how recently the area code was activated.
For the technical explainer, see our STIR/SHAKEN glossary entry.

Newest US area codes FAQ
Newest US area codes FAQ
What is the newest US area code in 2026?
The two newest US area codes as of May 2026 are 483 (Alabama — Montgomery and southeast, activated February 23, 2026) and 471 (Mississippi — Tupelo and northern MS, activated January 30, 2026).
The next activation is 465 for New York City (overlaying 347/718/917/929), scheduled for June 18, 2026.
Why are all new area codes overlays instead of splits?
Geographic splits — where part of a region gets a new code and must change numbers — became politically and commercially unpractical after the early 2000s.
Consumers and businesses objected to reprinting stationery, updating websites, and retraining staff. Regulators shifted to overlays, where the new code shares the same geography and only new subscribers get the new code. Existing numbers never change.
The trade-off: overlay regions must use ten-digit dialing for all local calls.
Are new area codes harder to get than established ones?
Not technically. The NANPA assigns number blocks from new overlay codes to carriers the same way as established codes. You can request a number in a newly activated code — like 483 or 471 — through any licensed VoIP provider that has obtained number inventory there.
Practically, a very new code may have limited inventory available through smaller providers. National VoIP providers like DialPhone maintain allocations across all active geographic codes including recent overlays.
Will my existing area code number be affected by an overlay?
No. Overlay codes only assign new numbers — your existing number in the original area code (say, 334 Alabama or 662 Mississippi) is never changed.
The only operational change for businesses in an overlay region: if you haven't already switched, you must dial ten digits for all local calls — including calls to numbers with the same area code.
Do new area codes get flagged as spam?
They can, at launch. When 689 overlaid 407 in Orlando in 2019, early 689 callers saw their calls flagged 'Spam Risk' by carrier analytics systems. The reason: those systems use 'unrecognized code' as a spam signal until databases update — typically a 3–6 month normalization window.
This is not a permanent condition. Carriers update their analytics, and calls normalize. To avoid the issue entirely, use a VoIP provider that includes STIR/SHAKEN A-attestation, which signals network-level verification regardless of code age.
Which states are adding new area codes most often?
California leads historically — it added multiple overlays in the 2010s and continues with codes like 738 (LA, 2024), 837 (Redding/Chico, 2025), and 357 (Fresno, 2025).
Texas is second — 621 overlaid Houston (713) in January 2025. Florida, New York, and Ohio also see frequent additions. These states have high population density and heavy mobile/IoT adoption, which exhausts number pools faster.
What is NANPA and who approves new area codes?
NANPA is the North American Numbering Plan Administrator — a neutral organization contracted by the FCC to manage the pool of 10-digit phone numbers across the US, Canada, and 20+ Caribbean nations.
When a state's number pool approaches exhaustion, the relevant state public utility commission (PUC) petitions NANPA for relief. NANPA evaluates options (split vs. overlay), recommends an approach, and the PUC approves the new code. See nationalnanpa.com for the official pending-code list.
Can I get a number in a brand-new area code for my business?
Yes. DialPhone supports all 313 active US geographic area codes including the newest overlays — 483 (Alabama), 471 (Mississippi), and 465 (New York City, from June 18, 2026).
Numbers in new overlay codes carry the same STIR/SHAKEN A-attestation as established codes, so your calls are verified from day one. See /pricing for plan details.
