CV is the hull type designation for an aircraft carrier. This is not to be confused with the aircraft carriers of today, which are CVN. The 'N' stands for nuclear powered. CVs were conventionally powered with boilers.
I'm not sure what specifically you're after here. Each aircraft has a hull number assigned when it's built, but each user also is assigned a registration number when the aircraft is put into service. All US registered aircraft, for instance, have a registration number beginning with the letter "N," and hence the registration number of a US aircraft is referred to as its "N number." See the Wikipedia page in the link below for more information on aircraft registration designations.

Would help if you state which country's Navy are you talking about. Answer: Carrier, of heavier-than-air aircraft. The "V" is a hangover from the old days (1920) when the USN also used to operate blimps. There were separate designations for lighter-than-air and heavier-than-air machines - V for heavier than air, Z for lighter than air. This is why US Navy squadrons (fixed-wing) have a "V" in their designation - because they operate non-blimps.
