This is correct. That is called the "broadcast code".
There is a unique 8 digit part number for each engine assembly. Engines are proliferated based on cubic inch displacement, carburetion, auto vs manual trans, emissions equipment, ignition type, etc. Anything that drives a unique base engine would create a unique part number.
The problem is...that it is difficult to remember an 8 digit part number from the time you look at the build manifest until you pick the correct engine from the rack. This is especially difficult when the engine part numbers happen to be similar, ie:
12345678
12345679
12345680
12445678
etc
In this case thinking "ok...I need to grab a '78..." could be a disaster.
So - the three digit code was created so it would be easier to remember.
The operator knows he needs to grab a "TAA", or a "TAB", or "TDK".
Much easier and eliminates many potential problems of grabbing and placing the wrong base engine.

All engines; anything with a high degree of proliferation (engines, trans, front/rear axles, radiators, battery cables, shock absorbers) would have a unique part number and corresponding broadcast code.
