What the number itself says

Reading 8ESYX.090AAA left to right: 8 is the model-year letter for 2008, ESY is the three-character code the EPA assigned to Easy Vehicle as certificate holder, X marks an off-road certification, .090 is the displacement in litres, so 90cc and AAA is Easy Vehicle's own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.
