Bet Din by State:

Please note that these listings are for orthodox Rabbinical Courts only. In order for the Get to be universally recognized within the Jewish world, it is essential that the Get procedures should be effected under the auspices of an orthodox Beth Din (Court of Jewish religious law). A Get that is done through a Conservative or Reform Rabbi is not currently recognized in Israel.

There are some states that do not have an Orthodox Rabbi.  Although Chabad Rabbis do not usually sponsor their own Rabinical Courts, they are listed in states where there are no other Orthodox Rabbis.
