IGM & DGM Numbers...
So what are IGM & DGM Numbers?
The IGM number or for that matter the DGM number of a vehicle was issued by the Italian Government to all Italain vehicles. On an Italian frame number the IGM or DGM number appear after the frame number.
DGM means simply Direzione Generale Motorizzazione that is the main place where all the vehicles are tested and they get an homologation.
IGM means Ispettorato Generale Motorizzazione, and is actually the same thing. The following number is a progressive homologation number, and OM is for 'omologazione', homologation. Older vehicles have IGM, and more recent ones DGM: in 1967 the name was changed from 'Ispettorato' to 'Direzione', hence the two different abbreviations.
