What is an RPO Code?
The term RPO is short for Regular Production Option and is General Motors’ standard coding for vehicle configuration options. An RPO code consists of a unique combination of three alphanumeric characters, like B30.
What does an RPO Code represent?
RPO codes are used to identify specific vehicle options or modifications such as paint colors, engine types, interior options, wheel types, etc.
How do I decode an RPO Code?

Where are the RPO Codes Located?
