Narrative:

Landed on runway 4R, then held short of runway 4L for landing and departing aircraft. Tower cleared us across runway 4L and we crossed runway 4L. On ground frequency we were told the clearance we acknowledged was for a different, same company aircraft. Supplemental information from acn 418278: received clearance to cross runway 4L. Read back clearance to cross runway 4L and crossed. About 3 mins later, ground control said runway 4L crossing clearance was for another airplane.
