World Manufacturer Identifier (positions 1–3)
Ram split off from Dodge as its own brand in 2010, but both still share Stellantis' WMI conventions. 1C3 marks a US-built Dodge passenger car, while 1C6 marks a US-built Ram truck from Sterling Heights or Warren, Michigan. Older Ram trucks (2009 and earlier, badged Dodge Ram) instead carry a 1D7 or 1D3 WMI — useful for spotting the pre-split generation at a glance.
