Narrative:
Departure control asked us to change our beacon code upon check-in. At that point the first officer realized he had not pulled up the pre departure clearance. When we did the checklist; I thought the pre departure clearance by the transponder was the correct one and only looked at the code. Everything looked like it was as filed so I didn't look very close at the other writing on the paper. I will next time.
