Alina,

The zip code shapefile for the whole state is carried
by census people. But census tends to be larger areas
than desired. I have found local offices be more
helpful because I have found the people locally that
produce the maps for the upstream organizations like
the state or council of governments.

You might google with shapefile being the beginning
string. Look for local offices or council of government
places.

Whole state of MA includes Boston.

Also the MIT site (Cambridge) might be able to help you further.

Good luck,
