If you’ve ever glanced at a car’s number plate and wondered, “What does that color mean?”, you’re not alone.
In India, number plates are more than just identifiers—they reflect ownership type, usage rights, fuel type, and even international status. From electric vehicles to foreign diplomats, each plate tells a different story.
