An Attorney may be listed in the commercial or yellow pages of a telephone directory only in the city where he maintains his office within this rule however, it is permissible to be listed in the commercial pages of a metropolitan area directory which includes the city where he maintains his office . The city of Metropolis is a large city surrounded by a number of suburban cities, A, B and C, etc. The company also publishes a combination directory for each of the suburban cities, containing both white and yellow pages.
Some attorneys maintain their offices in the suburban cities where they reside.
Many other attorneys reside in a suburban city but maintain their offices in Metropolis. Opinion A classified telephone directory listing is not a professional card within the meaning of Canon 39 and by its very nature constitutes advertisement which, strictly speaking, would be in violation of Canon 24 . The controlling question is whether the particular listing is reasonably calculated to serve the purpose of public convenience or rather is calculated to solicit business. In Opinion 241 we concluded that listings outside the community u here the attorney maintains his office smack more of solicitation than of serving the convenience of the public and we reaffirm that view. The Greater Metropolis Directory presents a somewhat different problem.
