Questions
›What car has a VIN starting with 3N1?
A Nissan built in Mexico — typically Aguascalientes-built Sentra and Versa. The three characters identify the manufacturer and plant region, not the specific model; characters 4–8 describe the model itself.
›Is 3N1 the same as the country of origin?
The first character alone gives the region — 3 indicates Mexico. All three together identify the specific manufacturer and division within it.
›Can I tell the model year from 3N1?
No. The WMI says who built the vehicle, not when. Character 10 carries the model year, and character 7 helps resolve which of its two possible years applies.
