Narrative:

After departing pdk, we contacted atlanta departure and were given clearance to climb to 6000 ft. Normally we get 5000 ft, but sometimes 6000 ft is given. Both the pilot flying and myself confirmed 6000 ft between us and set the altitude for our climb. As we were leveling at 6000 ft, departure said our assigned altitude was 5000 ft and to descend down to 5000 ft. I told him that he gave us 6000 ft not 5000 ft and we would begin a descent down to 5000 ft. At this time we were handed off to the next controller. As I checked on I told the controller we had been given 6000 ft and then back down to 5000 ft. He instructed us to maintain 6000 ft and, shortly after, a climb to a higher altitude. I asked him if any of this had been a problem or a mistake on our part and he said no. As we were climbing, I went back to the original controller and asked if any of this misunderstanding was a problem or a mistake and he said it was not a problem. There was no conflict of any kind that we know about.

Title: AN LJ45 CAPT RPTED AN A80 INTRAFAC COORD ERROR DURING DEP FROM PDK.

Narrative: AFTER DEPARTING PDK, WE CONTACTED ATLANTA DEP AND WERE GIVEN CLRNC TO CLB TO 6000 FT. NORMALLY WE GET 5000 FT, BUT SOMETIMES 6000 FT IS GIVEN. BOTH THE PLT FLYING AND MYSELF CONFIRMED 6000 FT BTWN US AND SET THE ALT FOR OUR CLB. AS WE WERE LEVELING AT 6000 FT, DEP SAID OUR ASSIGNED ALT WAS 5000 FT AND TO DSND DOWN TO 5000 FT. I TOLD HIM THAT HE GAVE US 6000 FT NOT 5000 FT AND WE WOULD BEGIN A DSCNT DOWN TO 5000 FT. AT THIS TIME WE WERE HANDED OFF TO THE NEXT CTLR. AS I CHKED ON I TOLD THE CTLR WE HAD BEEN GIVEN 6000 FT AND THEN BACK DOWN TO 5000 FT. HE INSTRUCTED US TO MAINTAIN 6000 FT AND, SHORTLY AFTER, A CLB TO A HIGHER ALT. I ASKED HIM IF ANY OF THIS HAD BEEN A PROB OR A MISTAKE ON OUR PART AND HE SAID NO. AS WE WERE CLBING, I WENT BACK TO THE ORIGINAL CTLR AND ASKED IF ANY OF THIS MISUNDERSTANDING WAS A PROB OR A MISTAKE AND HE SAID IT WAS NOT A PROB. THERE WAS NO CONFLICT OF ANY KIND THAT WE KNOW ABOUT.
