Boston area telephone exchanges, prior to 1948



The tables that this page leads to give the exchanges in use in the city of Boston, Mass. and vicinity for the period between the start of dial-oriented listings and the change in 1948 from three-letter to two-letter-one-digit exchanges. For the exchanges after 1948, please see the section of this website devoted to the post-1948 Boston exchanges.

Please note that at this time I have data from only one point in time, which is in 1946. No information has been acquired either before or after that time, and consequently no correspondences between pre-1948 and post-1948 exchanges can as yet be presented.
