Narrative:

Not sure if clearance given to taxi aircraft for takeoff. Taxi time less than 1 min to runway. We had problems getting en route clearance on ACARS and had to use radio to get clearance. After clearance received, we began taxi. At runway, we received takeoff clearance. We were not sure if we called and received taxi clearance. No indication from ATC there was a problem.
