Give the Assessor's office a call at 413-665-1400, ext. 106 to see if the information they have is accurate and up-to-date. If the address is incorrect, you will need to fill out a Change of Mailing Address form. You may obtain a Change of Mailing Address Request form from the Assessors' Office in the Town Hall or you may print yourself a copy. Completed forms go to the Assessors' Office.
