Please find in the attachment the full mapping of all possible response code and state combinations, per request and current product statuses. 

Please note that a lot of these are highly unlikely to ever be seen in actual use, but they are all plausible combinations.

Regarding the capitalized and non-capitalized states, capitalized states are what Movilitas receives back from the NMVS’s (“UNKNOWN” is filled in when no state is returned). Non-capitalized states are Movilitas - system-generated states.
