Find any 413- phone number in Massachusetts
The 413 area code is used for Massachusetts and portions of surrounding states, including western Connecticut, western Rhode Island, and westernmost parts of Vermont. It is one of the original area codes established in October 1947 as part of the North American Numbering Plan. The NANP is a system that assigns a unique three-digit number to each geographic area in North America for use by telecommunication companies.
The 413 area code is part of the NANP's original "split" plan, under which states and regions were divided into several distinct exchanges. This plan was used to accommodate the advancement of telecommunication technologies and the growing need for telephone numbers. As Massachusetts' population has grown, demand for additional numbers in the 413 area code has increased. As a result, new area code 857 was implemented in the Boston metropolitan area in 2001, and the 413 area code was reduced to its original boundaries.
