Narrative:

Climbing through FL350 center questioned us about assigned altitude. Previous controller assigned us FL370. We read back 370, but next controller never received notification of our being assigned FL370. Crew was advised no 'airspace conflict.' crew noted FL370 seemed a 'funny assignment,' since it was not requested by us, but otherwise not an unusual altitude assignment for an eastbound flight. Apparently there was lack of coordination between handoff center controllers. All aircraft equipment was functioning normally.

Original NASA ASRS Text

Title: ALT ASSIGNMENT NOT COORDINATED WITH ADJACENT SECTOR RESULTING IN A SYSTEM DEVIATION.

Narrative: CLBING THROUGH FL350 CENTER QUESTIONED US ABOUT ASSIGNED ALT. PREVIOUS CTLR ASSIGNED US FL370. WE READ BACK 370, BUT NEXT CTLR NEVER RECEIVED NOTIFICATION OF OUR BEING ASSIGNED FL370. CREW WAS ADVISED NO 'AIRSPACE CONFLICT.' CREW NOTED FL370 SEEMED A 'FUNNY ASSIGNMENT,' SINCE IT WAS NOT REQUESTED BY US, BUT OTHERWISE NOT AN UNUSUAL ALT ASSIGNMENT FOR AN EBND FLT. APPARENTLY THERE WAS LACK OF COORD BTWN HDOF CENTER CTLRS. ALL ACFT EQUIPMENT WAS FUNCTIONING NORMALLY.
