1956 GA license plate code question

[56buickinga]

Hello,

I have noticed on a few different 1956 GA plates before the numbers there are two letter codes one is h/c the other h/b. Does anyone know what this might mean?

Thanks

That usually designated a truck or other commercial vehicle. Car plates carry a one to three digit number prefix.

Thanks I figured it was for commercial use, but wanted to get someone's opinion who is more knowledgeable on the subject.
