Everything is included except a box. There are 5 phones however I don’t think that more than 3 of the phones work. I do know that the answering machine portion worked just fine for me. They each have a plug-in cord with charging base as well as the main base. The main base has a wall outlet as well as a plug in line. I only stopped using it because I didn’t need a second line and I have my cellphone. Instructions included. This could be good for seniors
