GTE operating companies

The GTE Operating Companies are separate telephone companies within Verizon that provide local telephone service to areas previously served by GTE. The GTE Operating Companies function much like the Bell Operating Companies and were arranged in the GTE corporate structure in the same fashion. The GTE operating companies are known for trading their telephone regions, and many of the GTE operating companies have seen a decrease in the number of states they provide service to since 1990.
