The 207 area code covers the entire state of Maine, from Portland and the southern coast to Bangor and the vast North Woods. One of the original area codes assigned in 1947, 207 served all of Maine by itself for over seventy years and now shares the state with the 729 overlay.

Geographic Coverage
The 207 area code is a statewide code covering all of Maine, including the largest city of Portland and neighboring South Portland and Biddeford along the southern coast, the twin cities of Lewiston and Auburn in the center, the state capital of Augusta, Bangor in the east-central region, and Sanford in the southwest. It borders New Hampshire and the Canadian provinces of Quebec and New Brunswick, and is the easternmost area code in the United States.
Time Zone
The 207 area code observes Eastern Time (ET). Clocks follow Eastern Standard Time (UTC−5) in winter and shift to Eastern Daylight Time (UTC−4) from mid-March through early November. All of Maine is on Eastern Time. As the easternmost state in the country, Maine is among the first places in the United States to see the sunrise each day. From the West Coast, this region is three hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 207 number at 12:00 PM local time.
Tip: Business hours across the 207 region generally run 9:00 AM to 5:00 PM Eastern Time, Monday through Friday.
How to Dial a 207 Number
Because area code 207 operates as part of an overlay, 10-digit dialing is mandatory for every local and long-distance call. You must dial the full 10-digit number (207 + the seven-digit line number) even when calling a neighbor across the street. For international callers, dial your country’s exit code, then +1 (the North American country code), then 207, followed by the seven-digit local number.
Scam Alerts for the 207 Area Code
Like every U.S. area code, 207 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Portland, Lewiston, Bangor, South Portland, Auburn, Biddeford, Augusta, Sanford should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Callers claiming you owe back taxes and threatening arrest unless you pay immediately. |
| Utility Shut-off | Fake Central Maine Power reps demanding payment to avoid disconnection in winter. |
| Storm / Heating Scam | Fake contractors or fuel dealers demanding upfront payment for winter storm repairs or heating oil. |
| Bank Fraud Alerts | Robocalls impersonating your bank about “suspicious activity” to phish account details. |
If you receive a suspicious call from a 207 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the Maine Attorney General’s Consumer Protection Division.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (Central Maine Power or Versant Power) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 207 caller making such a demand is a scammer.
History and Economy of the 207 Region
n
Area code 207 is one of the original 86 codes established in 1947, and it remained one of the last single-area-code states in the country until the 729 overlay was introduced statewide. The “207” has become a proud symbol of Maine identity, appearing on local brands, apparel, and slogans. The regional economy blends a historic maritime tradition with modern industry: Maine is famous for its lobster and seafood industry, and Portland has grown into a nationally recognized food, craft-beer, and tourism destination. Shipbuilding remains vital at Bath Iron Works, which builds destroyers for the U.S. Navy, while forestry and paper anchor the North Woods, potatoes and wild blueberries drive agriculture in Aroostook County, and tourism thrives around Acadia National Park, the rocky coast, and L.L.Bean in Freeport.
