Three new geographic area codes have gone into service in the United States so far in 2026 — 471 in Mississippi, 483 in Alabama and 465 in New York City — and every one of them is an overlay rather than a split.
That is the whole story of new area codes now: nobody’s number changes, a second code is laid over the same streets, and new lines start receiving it. The only things that move are the dates.
This tracker lists each code with the date NANPA records it as in service, the code it overlays, and what is scheduled next. It is updated as the record changes, and the date at the top of the page is when it was last checked.
New US area codes in 2026
Three geographic codes and two non-geographic ones have gone into service this year. “In service” is NANPA’s term for the day a code can first be assigned to a number — not the day permissive dialling began, which is usually months earlier and is the date most news coverage reports.
| Code | Where | Overlays | In service |
|---|---|---|---|
| 471 | Northern Mississippi — Tupelo, Oxford, Columbus, Greenville | 662 | January 30, 2026 |
| 483 | South-eastern Alabama — Montgomery, Auburn, Dothan | 334 | February 23, 2026 |
| 465 | New York City outer boroughs — Brooklyn, Queens, the Bronx, Staten Island | 718, 347, 929 (and 917) | June 18, 2026 |
| 542 | Non-geographic 5XX range — personal communications services | None | May 26, 2026 |
| 543 | Non-geographic 5XX range — personal communications services | None | September 21, 2026 |
465 is the one most people will meet. It is the fourth overlay on New York’s outer-borough complex, and because 917 also covers all five boroughs, a Brooklyn or Queens number can now begin with any of five codes. The 718 and 465 guides on this site cover what that means for a business being handed the new digits.
The 2025 cohort
Seven geographic overlays went into service in 2025, from northern California to Detroit. Houston’s 621 was the fifth code on a single complex; Detroit’s 679 was the first overlay on 313, which had kept the city itself on one code since 1947.
| Code | Where | Overlays | In service |
|---|---|---|---|
| 621 | Houston, Texas | 713, 281, 832, 346 | January 23, 2025 |
| 837 | North-eastern California — Redding, Chico | 530 | January 31, 2025 |
| 357 | Fresno and the San Joaquin Valley, California | 559 | March 26, 2025 |
| 748 | Western and northern Colorado — Fort Collins, Grand Junction | 970 | July 7, 2025 |
| 729 | Eastern Tennessee — Chattanooga, Johnson City | 423 | September 5, 2025 |
| 457 | Northern Louisiana — Shreveport, Monroe | 318 | September 25, 2025 |
| 679 | Detroit and the Downriver communities, Michigan | 313 | November 7, 2025 |
| 538 | Non-geographic 5XX range | None | October 28, 2025 |
The 2024 cohort
Eight geographic overlays in 2024, including 738 — the third code over central Los Angeles, where 213 and 323 already shared the ground — and 324, the first overlay laid over Jacksonville’s 904 after two earlier splits.
| Code | Where | Overlays | In service |
|---|---|---|---|
| 686 | Richmond and central Virginia | 804 | February 1, 2024 |
| 327 | Arkansas outside the centre and north-west — Jonesboro, Pine Bluff | 870 | February 20, 2024 |
| 324 | Jacksonville and north-eastern Florida | 904 | February 26, 2024 |
| 436 | Cleveland’s outer suburbs, Ohio — Lorain, Elyria | 440 | March 1, 2024 |
| 235 | Eastern and south-eastern Missouri — Columbia, Jefferson City | 573 | March 24, 2024 |
| 821 | Upstate South Carolina — Greenville, Spartanburg | 864 | August 19, 2024 |
| 924 | Southern Minnesota — Rochester, Mankato | 507 | August 30, 2024 |
| 738 | Central Los Angeles, California | 213, 323 | November 1, 2024 |
| 532 | Non-geographic 5XX range | None | November 4, 2024 |
What comes next: codes assigned but not yet in service
NANPA assigns a code when a state commission orders relief, then sets the in-service date once the carriers’ implementation schedule is fixed. Three US codes are in that gap today.
| Code | Where | Overlays | Scheduled |
|---|---|---|---|
| 565 | South-eastern Georgia — Savannah | 912 | December 6, 2027 |
| 451 | Western North Carolina — Asheville | 828 | Assigned; no date set |
| 761 | Louisville and north-central Kentucky | 502 | Assigned; no date set |
Canada runs on the same numbering plan and has its own queue: 273 over Quebec’s 418, 581 and 367 is scheduled for February 27, 2027; 568 over Alberta on June 10, 2028; and 851 over Nova Scotia and Prince Edward Island on May 27, 2028. The two most recent Canadian codes, 942 in Toronto and 257 in British Columbia, both went into service in spring 2025.
Codes people search for that are not new
A few codes show up in “newest area code” searches every month because they are unfamiliar rather than recent. For the record:
| Code | What it is | In service |
|---|---|---|
| 737 | Overlay on 512 — Austin, Texas | July 1, 2013 |
| 463 | Overlay on 317 — Indianapolis, Indiana | November 15, 2016 |
| 641 | Parts of northern, central and southern Iowa — Mason City, Marshalltown, Ottumwa | July 9, 2000 |
| 348 | Not assigned. No area code 348 exists in the North American Numbering Plan | — |
A call displaying 348 is not coming from a real North American number, because there is no such code to come from. The same caller-ID field that makes neighbour spoofing possible can carry any three digits, assigned or not.
The same goes for a longer list of codes that turn up in searches every month. None of these is assigned in the North American Numbering Plan as of NANPA’s October 2026 report: 247, 282, 328, 338, 342, 348, 373, 392, 426, 439, 454, 467, 486, 489, 583, 594, 596, 632, 642, 648, 654, 687, 695, 745, 749, 793, 827, 834, 892 and 953. Anything beginning with 0 or 1 — 105, 111, 116, 117, 140, 173, 176 — cannot be an area code at all, because the first digit of an area code is always 2 to 9. And 529, 532, 566 and the rest of the 5XX block are assigned but non-geographic, so they place a caller nowhere.
What a new overlay means if you run a business there
Nothing happens to the number you already have. An overlay never changes an existing line; it adds a second code to the same territory so that new assignments can continue. The change you notice is dialling: once the mandatory date passes, every local call needs all ten digits, which affects anything that dials for you — alarm panels, fax machines, call-forwarding rules and the speed-dial list in your phone system.
If you are being issued a number now, you may be offered the new code rather than the familiar one, because that is where the unassigned supply is. The new code is exactly as local; it covers the same streets. What it lacks is recognition, and whether that costs you answered calls depends far more on caller-ID attestation and your calling behaviour than on the digits — the 465 guide works through that in detail.
