Narrative:
Bwi departure gave us an altitude of 17000 ft, which the captain read back and I confirmed. We were then handed off to dca approach and the captain checked in calling 'out of 11300 ft for 17000 ft.' out of approximately 16300 ft, dca approach asked us if our assigned altitude was 16000 ft, and we responded that bwi departure had given us 17000 ft. I don't know about any conflicts, however, I believe dca approach gave an air carrier Y flight a TA on our position. I don't know if the air carrier Y was turned. I'm not sure what caused the problem, if there was a miscue between bwi and dca. We read back 17000 ft to both controllers.

Title: FLC OF A B757 RECEIVED AND READ BACK CLRNC TO 17000 FT AND THEN WHEN CLBING THROUGH 16300 FT, THE NEXT CTLR EXPECTED THEM TO STOP AT 16000 FT.
Narrative: BWI DEP GAVE US AN ALT OF 17000 FT, WHICH THE CAPT READ BACK AND I CONFIRMED. WE WERE THEN HANDED OFF TO DCA APCH AND THE CAPT CHKED IN CALLING 'OUT OF 11300 FT FOR 17000 FT.' OUT OF APPROX 16300 FT, DCA APCH ASKED US IF OUR ASSIGNED ALT WAS 16000 FT, AND WE RESPONDED THAT BWI DEP HAD GIVEN US 17000 FT. I DON'T KNOW ABOUT ANY CONFLICTS, HOWEVER, I BELIEVE DCA APCH GAVE AN ACR Y FLT A TA ON OUR POS. I DON'T KNOW IF THE ACR Y WAS TURNED. I'M NOT SURE WHAT CAUSED THE PROB, IF THERE WAS A MISCUE BTWN BWI AND DCA. WE READ BACK 17000 FT TO BOTH CTLRS.
