Narrative:

Today on descent enroute to long beach airport we briefed arrival to runway 30; which was indicated on ATIS as the arrival runway. Also; we briefed and discussed possible taxi routes between pilots possible taxi instructions to the FBO; taxi instructions included crossing runway 7R/25L. Upon close proximity to the airport; ATC switched the landing runway from 30 to 12. As the flying pilot; I landed the plane and we exited at D2 with instructions from tower; which included and repeated by me our call sign; which were 'air carrier abcx.' after the tower switching to ground; our suffix was pronounced again a few times by me; and by ATC. Instructions by the ground were 'taxi to FBO via delta foxtrot.' I replied to ATC the taxi instructions and began the after-landing checklist; continuing with the flight times and fuel usage. At this time; all my attention was directed to the checklist and the FMS. I completed my after-landing assignments at the time the aircraft started to cross runway 7R/25L; which is an inactive runway. At this point; I said two things; 'we are cleared on my side;' and after we crossed the runway; 'this would be a good time to submit a report.' shortly after that; ground control came on and said we missed the taxiway and gave us different instructions. 1. In order for our company to help us remember when we have a plane in the process of changing ownership; the suffix X has been implemented at the end of the call-sign; so that the pilots do not forget the limitation of not being able to leave the united states. In my opinion; this word has two meanings; taxiway or pink-slipped-plane. In some situations; I think it is possible to confuse this pink-slip code with a taxiway; simply because for so many years pilots have not been used to having any letters after the call-sign. This is what I think happened on this occasion. 2. After repeating a few times the suffix with the tower and ground frequency over a short period of time; this gives the impression that we are being given taxiway instructions--completely forgetting about the same call-sign letters which signify something completely different. This should be changed. 3. If on descent; shortly before landing ATC changes instructions with landing to another runway; it would be beneficial to establish a procedure which might include after landing on the un-briefed runway; stopping the aircraft on the taxiway; briefing the new taxi instructions; and after that; continuing with all after-landing checklists.
