Narrative:

Received a beacon code after receiving the departure clearance. While on taxiway M; and waiting in line; my first officer responded to ground control on a squawk code change. I heard the change provided by ground control but was not sure if it was for us. I questioned my first officer if that was for us and he convinced me it was. We continued and were cleared to taxi into position and hold and later cleared for takeoff. I did not think of it any further with the last 2 calls due to our original call sign was being used. We departed off of runway 9L; radio traffic was heavy and we were not given over to departure in the normal time as usual. Thinking tower was too busy; or they thought we were handed off; I switched frequencys to departure and received no answer. I switched back over to tower and asked for the frequency. I was able to make contact with departure at this time. Unfortunately; he was looking for aircraft Y and asked what runway we departed. I explained we were off of runway 9L. He seemed confused until another controller came over the radio and asked for an identify. This controller realized we were on the wrong squawk and gave us the correct one. She then gave us a heading to intercept the departure. We proceeded without incident and I was able to call departure control via telephone once we landed. I talked with a sector supervisor who was aware of the event. When I told this person; whose name I did not obtain; about the situation she advised that it was not a big deal and the first controller was in training. The second controller who took over was the trainer. I was advised that our flight was where it was supposed to be but the training controller did not know who we were due to the incorrect code.
