The 680 area code covers Central New York — Syracuse, Utica, Watertown, and the surrounding counties — as an overlay on the long-standing 315 area code, in service since March 11, 2017. It isn't a California code and it didn't replace anyone's number; it simply gave the region a second pool of numbers once ten-digit dialing became mandatory. Central New York sits in the Eastern Time Zone.
This guide covers exactly where 680 reaches, why New York chose an overlay instead of another split, the region's numbering history back to 1947, and what's behind the calls arriving from unfamiliar 680 numbers today.
Where the 680 area code reaches
The 680 area code location matches 315 exactly — 18 counties across Central New York and the North Country.
680 / 315 coverage by zone:
| Zone | Communities |
|---|---|
| Syracuse metro | Syracuse, Baldwinsville, North Syracuse, Solvay |
| Utica-Rome | Utica, Rome, Ilion, Herkimer |
| Finger Lakes north | Auburn, Geneva, Seneca Falls, Newark |
| North Country | Watertown, Ogdensburg, Massena, Potsdam, Fort Drum |
What 680 does NOT cover:
- Westchester County & NYC suburbs → 914
- Binghamton & the Southern Tier → 607
- Rochester & the Finger Lakes core → 585
- Hudson Valley (Orange, Putnam, Rockland, Ulster) → 845 / 329
Why 680 overlays 315 instead of splitting it
By the early 2010s, Central New York's supply of unused 315 prefixes was projected to run low. Rather than redraw the map and force part of Syracuse or Utica onto a new code — the way the 1954 split did — the New York Public Service Commission approved an all-services overlay on July 21, 2015: 680 was assigned to the identical territory as 315, becoming the first overlay area code in upstate New York.
What the overlay means for callers:
A Syracuse business on 315-XXX-XXXX and a new office across town on 680-XXX-XXXX sit in the exact same calling area — same rates, same local coverage. Mandatory ten-digit dialing (area code plus seven digits) took effect on February 11, 2017, a month ahead of 680 numbers becoming available, because the two codes can no longer be told apart from the seven-digit number alone.
Central New York area code history
1947 — Area code 315 was assigned as one of the original 86 North American area codes, covering nearly all of upstate New York outside Buffalo, Rochester, and Albany's original footprints.
1954 — As the Southern Tier grew, area code 607 split off to serve Binghamton and the surrounding region, narrowing 315's territory to Central New York and the North Country.
July 21, 2015 — With 315's remaining supply running low, the New York Public Service Commission approved the 680 overlay rather than another geographic split.
March 11, 2017 — New 680 numbers became assignable across the same 18-county footprint as 315, following mandatory ten-digit dialing that began that February.

Is 680 a California area code?
It's a common assumption — a lot of 3-digit codes starting with 6 or 8 land on the West Coast — but 680 has never been assigned to California. It's strictly a Central New York overlay on 315. If a caller ID shows 680, the call is coming from (or spoofing) the Syracuse-Utica-Watertown region of New York, not anywhere in California.
How to get a 680 area code number
Central New York's economy — anchored by Fort Drum, Syracuse's hospital networks, and steady small-business growth in Utica and downtown Syracuse — is part of why 315 needed a second code in the first place. Many of these growing businesses are moving their phone systems onto UCaaS (Unified Communications as a Service) — one cloud platform for calling, video, and messaging that scales as a company adds locations, much like the numbering growth behind 329, New York's other recent overlay code.

Time zone & how to dial a 680 number
Central New York runs on Eastern Time (ET) — EST (UTC −5) in winter, EDT (UTC −4) during Daylight Saving Time. Local calls within the 315/680 overlay require all ten digits: dial 1, then the area code, then the seven-digit number, even when calling across the street.
Is 680 a scam number?
Because 680 numbers are less familiar than the long-established 315, scammers frequently spoof the newer code to look like a fresh, local caller and catch Central New York residents off guard. Consumer complaint reports point to IRS impersonation, mortgage and loan solicitation, auto warranty pitches, and payday loan scams as the most common patterns tied to the code — often via "neighbor spoofing," where the caller ID mimics a nearby exchange.
The FCC's STIR/SHAKEN call authentication framework requires carriers to verify caller ID before a call connects, but no system catches everything — treat unexpected 680 calls asking for payment or personal details as suspicious.
