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.
