Narrative:
While operating last flight of the day we received an amended pre departure clearance clearance to climb via PITZZ4 except maintain 4;000 ft. We climbed via SID after takeoff with no issues. We leveled at 4;000 ft. When switching to houston departure we checked in and the instruction was climb via SID; that's it. The SID clearly states to climb to top altitude of 16;000 ft. So we did. Upon checking in with houston center we were inquired at what altitude we were; to which we replied that we were told to climb via SID and therefore we climbed to 16;000 ft. And not our final filed altitude of 14;000 ft. Upon the controller going off frequency and checking with previous controller; he came back and said climb and maintain 16;000 ft. Both captain and I thought this was a big gotcha as the controllers are supposed to always give an except altitude if other than what's on the SID. We proceeded to [destination] with no further issues but definitely with a lesson to take home.
