Narrative:

We were light weight climbing through FL32.5 and had been cleared to FL370. Climb rate was about 2000 FPM and course was direct to dbn VOR. I was flying and the captain was working the radio. He was doing something and did not hear another aircraft request FL330 as a final altitude. The controller told us to level at FL330 as a final. The captain responded FL330 in return. An immediate ATC clearance of turn right heading 020 degree and change frequencys from 119.77 to 133.3 occurred. I told the captain that FL330 was intended for another aircraft. The new controller asked our altitude which was level at FL340 (earliest we could get stopped). We informed him of confusion and he stated climb and maintain FL370, and that the clearance given was for another aircraft. The confusion stemmed from the jax controller reading back the wrong call sign. Little can be done to stop this type of seemingly small human error.

Title: ATC COORD RESULTS IN WRONG ACFT GIVEN ALT CHANGE.

Narrative: WE WERE LIGHT WT CLBING THROUGH FL32.5 AND HAD BEEN CLRED TO FL370. CLB RATE WAS ABOUT 2000 FPM AND COURSE WAS DIRECT TO DBN VOR. I WAS FLYING AND THE CAPT WAS WORKING THE RADIO. HE WAS DOING SOMETHING AND DID NOT HEAR ANOTHER ACFT REQUEST FL330 AS A FINAL ALT. THE CTLR TOLD US TO LEVEL AT FL330 AS A FINAL. THE CAPT RESPONDED FL330 IN RETURN. AN IMMEDIATE ATC CLRNC OF TURN R HDG 020 DEG AND CHANGE FREQS FROM 119.77 TO 133.3 OCCURRED. I TOLD THE CAPT THAT FL330 WAS INTENDED FOR ANOTHER ACFT. THE NEW CTLR ASKED OUR ALT WHICH WAS LEVEL AT FL340 (EARLIEST WE COULD GET STOPPED). WE INFORMED HIM OF CONFUSION AND HE STATED CLB AND MAINTAIN FL370, AND THAT THE CLRNC GIVEN WAS FOR ANOTHER ACFT. THE CONFUSION STEMMED FROM THE JAX CTLR READING BACK THE WRONG CALL SIGN. LITTLE CAN BE DONE TO STOP THIS TYPE OF SEEMINGLY SMALL HUMAN ERROR.
