What the number itself says

Reading 9GZHC.049N1H left to right: 9 is the model-year letter for 2009, GZH is the three-character code the EPA assigned to Guangzhou Haojin (America) as certificate holder, C marks a highway (street-legal) certification, .049 is the displacement in litres, so 49cc and N1H is Guangzhou Haojin (America)'s own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
