While operating flights it came to my attention that these flights were filed and released by our company operations above flight level 290 in ADS-B required airspace. The affected airspace were Vietnam; China (Sanya) and Hong Kong.  I contacted operations a couple times during this week with questions about our equipment coding on our flight plans. The questions arose from inquiries from Hong Kong clearance delivery and departure control about our capabilities to accept altitudes FL290 and above.  Operations informed me that the coding on the flight plans was correct and would look into the problem with the higher altitude confusion. The response I received; was that we were RNP4 authorized and should not be limited below FL290.After further research; I discovered that we do not have Operations Specifications approval to operate ADS-B equipment in these FIR's. I became aware of this after our last trip into VHHH.
While operating flights Operations Department filed flight plans and issued the flight plans to the crew having the crew operate the aircraft above FL290 into airspace that required ADS-B; airspace affected were Vietnam; China (Sanya) and Hong Kong.ADS-B is installed and operational in the aircraft. Guidance for its use is found in the FCOM. After; discussions with Company operation concerning the filing strip and discussing the inquires by Hong Kong and China ATC the flight crews concern was not alieved. The crew researched documentation found that the company had not been issued operation specification; which is required for the use ADS-B.
A US carrier aircraft operating internationally with ADS-B installed did not have the ADS-B Operations Specification on file indicating its aircraft were authorized flight above FL290.
