One of the original area codes from 1947, 207 has never been split or overlaid — a genuine rarity in the United States. Whether you received an unexpected 207 call, you want to know where is 207 area code and what state it covers, or you are setting up a Maine business line, this guide explains the location, why Maine still has just one code, dialing and time zone, spam safety, and how to get a 207 phone number.

The 207 area code location is the entire state of Maine — every city, town, and island. To answer the top search, where is 207 area code: Maine sits at the far northeastern tip of the United States, in New England, bordering New Hampshire to the west and the Canadian provinces of Quebec and New Brunswick. Its population clusters in the south around Portland, the largest city, along with Lewiston, Auburn, Bangor, South Portland, Biddeford, and the state capital, Augusta.
From the southern beaches up through the Mid-Coast, Down East, and the western mountains and North Woods, every local number across that range is a 207. And no — despite the search 207 area code California — it is a Maine code on Eastern Time, not a West Coast one.
Most of the country has watched its area codes multiply. Maine has not. The 207 code has served the whole state since 1947 without a single split or overlay, making Maine one of only about a dozen single-area-code states left. Even compact New England neighbors outgrew their original codes — Boston's 617 area code had to add an overlay as its numbers ran short.

There is a practical upside to a single code: for decades, Maine could place local calls with just 7 digits. Numbering practices have since standardized toward the full 10-digit number, but that one-code simplicity is still part of what makes a 207 feel like a statewide handshake.

Maine's license plates say "Vacationland," and for a huge share of local businesses that coastal-and-outdoors brand is the product. Lobster and seafood, lighthouses and the rocky Atlantic shore, Acadia and the lakes, Portland's nationally known food and craft-beverage scene, and the timber of the North Woods all run on the same idea — and customers expect to reach a real Maine number, not an out-of-state call center. A virtual 207 number gives you that local signal from anywhere.
For a Maine business, a 207 number is not just a phone line — it is proof you are part of Vacationland, not calling from away.
A common question is whether 207 is a cell phone code. It is not specific to mobile — like every US geographic code, 207 covers both landlines and cell phones, so a 207 on a mobile simply means a Maine-based number. To dial one, use the full 10-digit number:
The 207 region runs on Eastern Time — EST (UTC−5) in winter and EDT (UTC−4) in summer, the same clock as Boston and New York. As the easternmost state, Maine is among the first places in the country to see sunrise, but for scheduling it is standard Eastern Time, three hours ahead of the US West Coast.

If unfamiliar 207 area code numbers keep calling, the answer to is 207 area code a scam is that the code itself is not. It is almost always "neighbor spoofing" — a scammer fakes a local 207 caller ID so the call looks familiar and you are likelier to answer. The overwhelming majority of 207 traffic is ordinary Maine people, businesses, and services.
Watch for fake Central Maine Power shut-off threats, phony IRS demands, auto-warranty robocalls, Medicare cons, and spam texts to 207 cell phones. Stay safe by never giving personal or financial details to an unexpected caller, letting unknown numbers reach voicemail, and learning how to recognize and report spam calls and texts through the FTC.
Setting up a 207 phone number for your business takes three steps:
Numbers usually activate within 24 to 48 hours and stay fully portable under FCC rules, so your Maine line follows you even if you change providers.
The 207 area code is more than a routing prefix — it is the phone identity of an entire state. Since 1947 it has stood for Portland's harbor, the lobster boats and lighthouses of the coast, Bangor and the North Woods, and the seasonal businesses that power Vacationland, and as one of the last single-code states, Maine wears 207 as a statewide badge on every caller ID.
For any business serving customers in Portland, Bangor, Lewiston, Augusta, or anywhere across Maine, a 207 number is the clearest local signal there is — and with virtual provisioning, you can carry it from anywhere.
The 207 area code covers the entire state of Maine, in the far northeast of the United States. Its main cities are Portland, Lewiston, Bangor, South Portland, and Auburn, plus the capital, Augusta. It runs on Eastern Time and is not in California.
207 is in Maine — and it is the only area code for the whole state. It is one of the original 1947 area codes and has never been split or overlaid, making Maine one of about a dozen single-area-code states.
No single area code is only for cell phones. The 207 code covers both landlines and mobile numbers throughout Maine, so a 207 number on a mobile phone simply means a Maine-based cell line.
Maine has a relatively small population spread across a large area, and the 207 number supply has kept pace with demand since 1947. Because the code has never run low, the state has never needed a split or an overlay — unlike most of the country.
The 207 area code observes Eastern Time — EST (UTC−5) in winter and EDT (UTC−4) during daylight saving, the same clock as Boston and New York City. Maine is the easternmost state, so it sees sunrise early, but it is 3 hours ahead of the US West Coast.
Choose the number type (local DID, business line, or vanity pattern), reserve an available 207 number from a provider's inventory, and configure SIP routing to your softphone or PBX. Because 207 is Maine's only code, any Maine local number is a 207; most go live within 24 to 48 hours and are fully portable under FCC rules.
