Massachusetts area codes

Massachusetts attained statehood in 1788 and is the seventh smallest state in the United States. Despite its small size, the state is diverse in population and is home to more than seven million residents. That means there are at least 7 million phone number owners. These phone number owners use different Massachusetts area codes depending on their location. Publicly available information on a phone number owner is available on the Massachusetts phone numbers database.

Until the mid-twentieth century, if you needed to call a person within Massachusetts, you would need to contact a human switchboard operator who routes your call to the other person based on the address you provided.

The switchboard system was confusing, arduous, expensive, and impractical for long-distance phone calls, even within Massachusetts. Area codes replaced switchboards as an efficient and faster way to facilitate phone calls

There are nine Massachusetts area codes. Each three-digit code represents a small geographical area within Massachusetts.

To put it into perspective, think of a phone number as a physical address. So, if you consider the typical Massachusetts phone number: 617-NPP-XXXX. 617 is the area code, which denotes the city or town within Massachusetts. The three-digit prefix code, NPP, would be the street name, and XXXX, the line number, would be the house number unique to the person you are calling.

Massachusetts started with two area codes for Eastern and Western Massachusetts. But as the population grew, the North American Numbering Plan Administrator approved the creation of nine area codes. Because the state mostly used overlay to create new area codes, there are still residents with the old area code.

Besides connecting you with the person you wish to call, area codes also let you identify an unknown caller’s location. You will also know if the call came from a landline or mobile phone by looking at the area code. A phone number search on the Massachusetts phone numbers database lets you see the caller’s personal information and public records associated with that caller.
