The 330 area code spans northeast Ohio below Cleveland — Akron at the center, Canton to the south, Youngstown and Warren along the Pennsylvania line — with a footprint reaching Brunswick and Medina in the west, East Liverpool on the Ohio River, and Wooster, Millersburg, and New Philadelphia across its southern tier. It entered service on March 9, 1996, carved from Cleveland’s 216, and since October 30, 2000 the same stretch of Ohio has also answered on the 234 overlay.
Getting an unexpected 330 call? On the screen it reads as Akron, Canton, or Youngstown — often a business courting northeast Ohio — but treat that as a hint, not proof: caller ID can be spoofed into any familiar prefix.

Ohio’s telephone map sat frozen for forty-nine years — four codes, no changes. Then 330 arrived and made a habit of going first: the state’s first new area code since 1947, the territory that hosted Ohio’s first overlay, and the first place in the state where every local call went to ten digits. The rest of Ohio followed piecemeal — Toledo’s 419 when the 567 overlay arrived in January 2002, Columbus in 2016, Dayton in 2020, 440 and 513 not until 2021 — and Cleveland’s 216 dials seven digits to this day.
The map: from Brunswick to East Liverpool
The rate-center map NANPA attached to Planning Letter PL-213 draws the footprint plainly. Akron anchors the middle. Canton, Massillon, and Alliance hold the south; Youngstown, Warren, Niles, and Hubbard run up the eastern edge; Kent and Ravenna sit between the two poles. Westward the code takes in Medina, Brunswick, and Wadsworth, and the southern tier rolls through Wooster and Millersburg to New Philadelphia and down to East Liverpool.
That is the old rubber-and-steel corridor sharing one prefix pool — mill towns, college towns, and Amish country on the same code, all of it in the Eastern time zone.
Ohio’s map, frozen since 1947
NANPA’s database records Ohio’s original quartet — 216, 419, 513, and 614 — entering service together on January 1, 1947. That arrangement outlasted the rotary dial: no state code was added, moved, or split for nearly half a century, even as 216 came to carry both metro Cleveland and the industrial corridor south of it.
330 broke the seal. Assigned on November 17, 1995 — NANPA’s record cites industry letter IL-95-11-008 — it entered service on March 9, 1996 and took Akron, Canton, Youngstown, and Warren off Cleveland’s hands. The dam held briefly: Dayton’s 937 split from 513 that September, and 216 needed a second cut when 440 entered service in August 1997. How growth forces exactly these choices is the subject of our area code explainer.
234: the overlay Ohio met first
Four years after the split, 330 was running short again. Every employer, pager fleet, and dial-up pool consumed NXX prefixes in 10,000-number blocks, and this time Ohio chose the modern remedy: in Dockets 99-669-TP-COI and 97-884-TP-COI, Opinion and Order of October 28, 1999, the Public Utilities Commission of Ohio approved a full-services distributed overlay — the state’s first.
NANPA assigned 234 for the assignment on November 5, 1999 and set the timetable in Planning Letter PL-213 on February 21, 2000. The rollout had carrier-grade choreography: after April 1, 2000, any carrier could verify its routing by dialing 234-333-1234, a test number answering through an Akron switch with a recorded announcement, and no 234 prefix was allowed to take effect before launch day, October 30, 2000.
Ten digits before the rest of Ohio
The dialing change outran the overlay itself. PL-213 opened permissive ten-digit dialing at 12:01 a.m. on April 1, 2000 and made it mandatory on October 1, 2000 — four weeks before 234 even entered service. No other Ohio code required ten digits at the time; 330 dialers were the state’s first, and NANPA’s dialing records still show the plan today: ten digits for every local call, 1+10 for toll. Two years later, Oakland County’s 248 ran the same first-in-the-state conversion for Michigan.
The head start looked prescient in 2021. NANPA’s Planning Letter PL-556 of January 8, 2021 listed 82 area codes still dialing seven digits with 988 in use as a prefix — all forced to convert by October 24, 2021 so the crisis line could launch. Ohio’s two entries were 440 and 513. The 330/234 complex had nothing to change; it had been dialing ten digits for twenty-one years.
Prefixes to spare until 2042
The overlay settled the question for a generation. NANPA’s April 2026 NPA exhaust analysis pegs the combined 234/330 prefix pool’s exhaust in the third quarter of 2042 — a full year beyond the October 2025 forecast, on reduced demand — and the administrator’s database shows the code clear of jeopardy, with no relief proceeding open. Northeast Ohio’s numbering, turbulent through the late 1990s, has settled into one of the calmer stretches on the national map.
The business case for Akron-local digits
On a phone screen, 330 reads as Akron, Canton, or Youngstown the way 216 reads as Cleveland — and the overlay adds a vintage marker, since no 234 number could exist before October 30, 2000. For a company selling into northeast Ohio from anywhere at all, that local read is the difference between a pickup and a voicemail; our local presence guide covers the mechanics. Treat the display as a hint rather than proof, though — caller ID can be spoofed into any familiar prefix, so confirm sensitive calls through a listing you trust.
SIPNEX operates under its own FCC license — a direct carrier authorization, not a resale arrangement — and provisions local DIDs by rate center, 330 and 234 included as inventory allows. SIP trunking carries those numbers to any PBX or dialer, and every outbound call gets its A-level signature from SIPNEX’s own STIR/SHAKEN certificate — something no spoofed Akron number can show.
330 area code, asked and answered
Which cities does the 330 area code cover?
Akron sits at the center, with Canton, Massillon, and Alliance to the south, Youngstown, Warren, and Niles along the eastern edge, and Kent, Ravenna, Medina, Brunswick, Wadsworth, Wooster, Millersburg, New Philadelphia, and East Liverpool filling out the rate-center map NANPA published with Planning Letter PL-213. Since October 30, 2000 the identical territory is also served by the 234 overlay.
When did the 330 area code split from 216?
It entered service on March 9, 1996 — NANPA’s database records the assignment on November 17, 1995 under industry letter IL-95-11-008 — making it Ohio’s first new code since the original four of 1947. Cleveland and its inner suburbs kept 216, which needed another cut soon after: 440 entered service in August 1997.
Do 234 and 330 numbers cover the same area?
Yes. 234 is a full-services overlay approved by the Public Utilities Commission of Ohio in its October 28, 1999 order and in service since October 30, 2000 — the first overlay in Ohio. Calls dial, route, and cost identically across both codes. The only real difference is age: NANPA barred 234 prefixes from taking effect before launch day, so every 234 number is newer than October 2000.
Has the 330 area code always required ten-digit dialing?
No — local calls were seven digits until the overlay arrived. Planning Letter PL-213 opened permissive ten-digit dialing on April 1, 2000 and made it mandatory on October 1, 2000, before any other Ohio code required it. When PL-556 forced 82 seven-digit codes to convert ahead of the 988 hotline in 2021, Ohio’s entries were 440 and 513 — 330 was two decades into ten-digit dialing by then.
When will the 330 area code run out of numbers?
Not for a long while. NANPA’s April 2026 NPA exhaust analysis shows the shared 234/330 prefix pool lasting into the third quarter of 2042 — a year past the October 2025 estimate — and NANPA’s database lists nothing against it — no jeopardy, no relief docket.
Can my business get a 330 number without an Ohio address?
Yes. A DID is issued from a rate center, not from a street address, and SIP trunking delivers its calls to wherever your team actually answers. Availability varies by rate center on any given day — and if a rate center has no 330 left, a 234 number reads every bit as northeast-Ohio on the display. SIPNEX issues local DIDs and connects them to your existing phone system.
From Akron to Youngstown and every rate center between, SIPNEX supplies the carrier layer: local DIDs across US markets, toll-free through a RespOrg registration, SIP trunks built for dialer traffic, and A-level attestation signed with its own STIR/SHAKEN certificate under a direct FCC license. One call to (833) 665-2220 starts it — or talk to the team online and compare rates first.
