Other RTO Codes in Tiruchirappalli You Might See
Tiruchirappalli (Trichy) is a major city, and like many urban hubs in Tamil Nadu, it’s divided into multiple RTO zones for better transport management.
So even if TN 48 covers Srirangam and Musiri, you might also see:
- TN 45: For vehicles from Trichy City (central business and residential areas)
- TN 81: For vehicles from Tiruverumbur (includes industrial and suburban zones)
This RTO segmentation helps streamline registration, road taxes, enforcement, and public services. For travelers, it’s another interesting way to see how well Tamil Nadu’s road network is organized, even down to the numbers on your license plate.
