380 Area Code: Columbus, Ohio — The 614 Overlay Explained

Introduction

The 380 area code is a full overlay on 614, put into service on February 27, 2016 across Columbus and Franklin County, Ohio. It was first approved by state regulators back in 2001 but delayed for over a decade as number-conservation measures stretched out the existing 614 supply. It shares the exact same footprint as 614 rather than defining a separate region, so 380 and 614 numbers coexist side by side in Columbus, Dublin, Hilliard, Gahanna, and Westerville. It is not connected to the 740/220 overlay pair, which covers Newark, Lancaster, and the ring of counties surrounding Columbus rather than the capital itself.

A local area code matters even more in a market as corporate-dense as Columbus, where Fortune 500 headquarters, a Big Ten flagship university, and major financial-services operations centers all compete for the same customers' attention. Because 380 is a full overlay, every call in the region, even a local one, requires all 10 digits to be dialed.

• 380 overlays the existing 614 area code — not 330 — across Columbus and Franklin County
• It went into service February 27, 2016, once the 614 number pool neared exhaustion
• Letsdial issues a 380 number instantly, with forwarding, IVR, texting, and analytics built in

Where Exactly Does the 380 Area Code Serve?

380 is a full overlay of 614 only. It does not extend into Newark, Lancaster, Zanesville, or the rest of the counties ringing Columbus — those communities sit in 740/220 territory, a separate overlay pair covering central and southeastern Ohio outside the capital. 380's actual coverage is the compact, dense core around Columbus itself:

• Franklin County — Columbus, Dublin, Hilliard, Gahanna, Westerville, Reynoldsburg, Grove City, and New Albany
• Delaware County (portion) — southern communities bordering Columbus's northern suburbs
• Fairfield County (portion) — Pickerington and Canal Winchester, not the city of Lancaster further south
• Union County (portion) — Marysville and the surrounding townships

Because 614 and 380 share identical geography, a business or resident anywhere in this footprint could be assigned either code with equal likelihood — neither carries more local credibility than the other.

The combined 614/380 footprint is often described as "all but synonymous with Columbus" — a compact, urban core rather than the sprawling multi-county reach of neighboring overlays. Because 380 is a full overlay rather than a split, every call placed within the region — even a local call between two neighbors in the same Dublin exchange — requires all 10 digits, a rule that has been mandatory since January 30, 2016.

Columbus's population growth has outpaced most Midwestern peers over the past decade, and the metro is regularly cited among the fastest-growing large cities in the region — a trend that has pushed continued demand into the 380 overlay even as the original 614 code still carries the bulk of long-established residential and business numbers. The 740/220 guide covers the neighbouring ground.

Columbus's Corporate Core: Ohio State, Nationwide, and Central Ohio's Biggest Employers

Few overlay footprints this size carry as much corporate weight. The Ohio State University's main campus sits at the heart of the 614/380 territory, enrolling more than 60,000 students and anchoring a research and medical economy that ripples through every surrounding suburb.

Nationwide Mutual Insurance Company is headquartered in downtown Columbus and remains one of the region's largest employers, while L Brands — the parent of Victoria's Secret and Bath & Body Works — has run its global headquarters and distribution operations from the same 614/380 footprint for decades. JPMorgan Chase operates one of its largest employment centers outside its home markets in Columbus, and Honda's original North American assembly plant in Marysville, within the Union County portion of the overlay, has anchored the region's auto-manufacturing economy since 1982.

Columbus is also home to Battelle Memorial Institute, the world's largest independent research and development organization — a nonprofit founded in 1929 that now manages roughly $6.5 billion in global R&D annually and operates national laboratories for the U.S. Department of Energy. That research base, combined with Ohio State's status as one of the largest public universities in the country, gives the 614/380 footprint an unusually deep pipeline of engineering and scientific talent for a Midwestern capital of its size.

New Albany, on the northeastern edge of the 614/380 footprint, is now the site of Intel's $28 billion "Silicon Heartland" chip manufacturing campus — the largest single private-sector investment in Ohio history when it was announced in January 2022. Production is targeted for the early 2030s, but the project has already pulled a wave of semiconductor suppliers and construction activity into the northeastern Columbus suburbs, adding a fourth major growth industry to the region's insurance, retail, and pharmaceutical base.

For a business calling into this market — whether pitching a Nationwide vendor desk, a Chase back-office team, or a Columbus household near campus — a number that displays as local rather than out-of-state measurably improves answer rates in a city this used to screening unfamiliar area codes.

How the 380/614 Overlay Works

614 dates to 1947, when it was assigned to a much larger swath of southeastern Ohio as part of the original North American Numbering Plan. In 1998, the southern portion of that territory split off to form area code 740, narrowing 614 down to Columbus, Franklin County, and slivers of the surrounding counties — the footprint 380 overlays today.

Dialing a 380 Number

Every call within the 614/380 region — local, long-distance, or international — requires the full 10-digit or 11-digit format. There's no shortcut back to 7-digit dialing, even for calls between two numbers on the same exchange.

• Local: dial the area code plus the 7-digit number, e.g. 380-555-1234
• Long-distance within the US: dial 1, then the area code and number, e.g. 1-380-555-1234
• International: dial the exit code (011 from the US/Canada, 00 from Europe), then 1, then the area code and number

Managing Calls, Caller ID, and Scam Protection with a 380 Number

Call Management Features

• Call filtering and blocking to cut down on unwanted calls before they reach your team
• Forwarding and routing so calls reach the right desk, department, or after-hours line automatically
• Voicemail-to-email and transcription, with alerts sent the moment a message arrives
• Caller ID and screening so your team can prioritize known callers before answering

If you receive an unknown call from a 380 number, a reverse phone lookup service can identify the carrier, general location within the Columbus metro, and — where publicly available — caller identity details, using the full 10-digit number.

Recognizing 380 Area Code Scams

A newer overlay code is a favorite target for spoofing, since recipients are less familiar with it than with the long-established 614. Watch for utility-disconnection threats, fake IRS collection calls, tech-support scams claiming your computer is infected, and generic robocalls pushing unsolicited offers.

• Never share personal or financial information with an unverified caller
• Register with the National Do Not Call Registry at donotcall.gov
• Report suspicious 380 calls to the FTC at reportfraud.ftc.gov
• Use call-blocking apps such as Nomorobo, Truecaller, or Hiya to screen spoofed numbers automatically

Conclusion

Area code 380 gives Columbus and Franklin County room to grow without displacing a single existing 614 number.
