What the number itself says

Reading SSSTC.169MCA left to right: S is the model-year letter for 2025, SST is the three-character code the EPA assigned to Scooterstar Motors as certificate holder, C marks a highway (street-legal) certification, .169 is the displacement in litres, so 169cc and MCA is Scooterstar Motors' own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
