The 207 area code belongs to the whole territory of Maine. This telephone prefix has been the only active codification for the state since its introduction. 

The value of this state lies in its great agricultural industry and the massive production of dairy supplies, such as chickens and eggs. Also, this territory encompasses about 535 certified organic farms and, due to its large forest area, it is a relevant paper and wood manufacturer. 

Maine owns 16 counties and 488 incorporated municipalities that consist of cities, towns, and plantations, including PortlandLewiston, and Bangor. All of them are covered by the same area code.

1. History

Introduced in 1947, this dialing code hasn’t been divided or overlaid ever since. This area code is one of the 86 original codifications established by AT&T and the Bell System for the North American Numbering Plan (NANP). 

Since the creation of the NANP, only twelve states have remained with their original numbers serving the full area. They are they're Alaska, Delaware, Hawaii, Idaho, Maine, New Hampshire, North Dakota, Rhode Island, South Dakota, Vermont, and Wyoming. 

Today, the 207 area code is not part of expansion projects until the first quarter of 2025. This deadline has been extended several times for different technical reasons. However, the split of this prefix at the present decade is a fact.

2. Location

Maine lies in the New England region of the United State, located in the northeastern corner of the territory. Maine is the only state bordering a single state in the country, which is New Hampshire to the west of the region. Besides, it delimits the Atlantic Ocean to the southeast and the Canadian provinces of New Brunswick and Quebec to the northeast and northwest, respectively. 

At being the largest region of the six New England states, Maine represents nearly half of New England’s total area. This location is well-known for its long, cold, and snowy winters, the main characteristic of this portion of the U.S. 

This state is the 43rd most populous with around 1,344 million inhabitants and the 44th largest in the country. The capital of the state is Augusta; however, it’s not the most crowded city in the area. 

Maine belongs to the Eastern Time Zone, just like Maryland and the 301 area code and the 443 area code, and Connecticut, among other regions. The 207 area code contains 486 non-unique postal area zip codes and covers 32508.49 square miles

Adjacent codes

At being the only prefix number covering the state, the 207 area code doesn’t possess any overlay yet. Nevertheless, there are three adjacent codes serving in near regions. 

The codifications 418, 581, and 367 are three dialing codes surrounding the eastern portion of the Canadian province of Quebec, at the northwest of Maine. The activation of the 418 dates from 1947 by AT&T, when it used to cover the northwestern territories. The 581 area code started running in 2008, as its first prefix. And the second one, the 367, in 2017.

On the American side, this prefix is near the 603 area code of New Hampshire.
