Massachusetts / Lic # in Correspondence

Does the requirement of including a license number in any and all correspondence (ad, business card, etc) still exist in Massachusetts?

I see the requirement of displaying an A or C certificate in the primary place of business / office(s) is still required, and carrying a B or D card in the wallet is still listed in Chapter 141 Section 3 (9) but what about ads, business cards, or even websites?

I see them on trucks. It used to be a problem around here because some builders would get the permits for the entire job and use someones license number and then do the work themselves. That area had so much trouble we have to get the permits notarized. A real PITA
