I don't think they do any longer but Verizon used to send me FIOS flyers on a fairly regular basis and when I went to their site it looked as if it wasn't actually available at my address (where I get Comcast).

Also amusingly, both Comcast and Verizon have the very old (as in multiple decades) name for the street I live on as my address. It's only somewhat wrong (the name used to have a North on it)--but it is still wrong.
