Does a Boeing 747-830 exist and if it does, is there any difference to a 747-8 (748) Two years ago I've uploaded a video of the Lufthansas Boeing 747 &quot;D-ABYA&quot; to Youtube. I am currently receiving some angry comments on that video because the title reads &quot;747-830 with new Lufthansa livery performs low pass at Hanover Airport&quot;. Many people are angry with the label &quot;747-830&quot;, telling me that no such thing exists and that the featured airplane is a 747-8 or a 748.
Back when making the video, if I recall correctly, I looked up the type on Jetphotos. It reads &quot;Boeing 747-830&quot;. The same is true on Flightradar24. airframes.org tells me the type is B748 and the model is 747-830. However, I could not find a reference to &quot;747-830&quot; on boeing.com.
What are the differences between type and model? Is a type 747-8 always a 747-830? Or are there other models with a similar name (747-8xx)? Am I correct in saying that the airplane is a 747-830?
Until 2016 Boeing included customer codes into the aircraft model names. Your example 747-830 decodes as follows:

747: This is the general aircraft series.
-8: The 747-8 variant (in this case, a 747-8I, where I is for Intercontinental, the passenger variant).
30: The customer code for Lufthansa or Condor Flugdienst (see e.g. Wikipedia for a list of customer codes).

So this makes it a Boeing 747-8 produced for Lufthansa (Condor does not have one).
The term B748 is the ICAO code for the 747-8.
