Narrative:
Atl clearance delivery assigned us 4000' on departure instead of the normal 10000'. We (the crew) thought this unusual, but figured it was to get us under arrival traffic since we were going due north and just to knoxville. On departure I read climbing through 2200' to 4000'. After a few mins in the air departure control asked what our altitude was. When we responded 4000' they said to climb immediately to 10000'. They also asked who assigned us to 4000', instead of the normal 10000'. To my knowledge there were no conflicts. Supplemental information from acn 131576: on takeoff we called departure and told them we were climbing to 4000'. They made no comment. We were vectored north and leveled at 4000'. Approaching dobbins AFB we were called by departure and asked our altitude. It sounded like a supervisor came on and asked our assigned altitude. He seemed surprised.we told him our clearance and that we had called departure after takeoff telling them we were climbing to 4000'. He said he'd check into it.
