ATC Human Performance
Center gave us a climb from FL290 to FL330 and switched us to another ZTL controller. Passing FL310 we asked controller (new one) to verify clearance was to FL330 as our filed altitude was FL310. He said that we were to maintain FL310. By this time, I was at FL313 and immediately initiated a descent. We informed controller and he said there was 'no problem' and to maintain FL310. Maximum altitude we attained was FL315, there were no traffic conflicts.

Title: AN MD80 CAPT RPTED ALT OVERSHOT, DUE TO CONFUSION BTWN 2 ZTL CTLRS.
Narrative: CTR GAVE US A CLB FROM FL290 TO FL330 AND SWITCHED US TO ANOTHER ZTL CTLR. PASSING FL310 WE ASKED CTLR (NEW ONE) TO VERIFY CLRNC WAS TO FL330 AS OUR FILED ALT WAS FL310. HE SAID THAT WE WERE TO MAINTAIN FL310. BY THIS TIME, I WAS AT FL313 AND IMMEDIATELY INITIATED A DSCNT. WE INFORMED CTLR AND HE SAID THERE WAS 'NO PROB' AND TO MAINTAIN FL310. MAXIMUM ALT WE ATTAINED WAS FL315, THERE WERE NO TFC CONFLICTS.
