ToggleIf you’re cruising through Tamil Nadu, especially in and around Chennai, chances are you’ll spot plenty of vehicles with TN 13 on their number plates. But what does that really mean?
TN 13 is the official vehicle registration code for Ambattur, a busy and fast-developing suburb that’s part of the Chennai district. Known more for its industries and residential neighborhoods than tourist landmarks, Ambattur still plays a central role in the region’s transport network, especially if you’re on a road trip or renting a vehicle locally.
For locals, TN 13 is part of daily life. But for travellers, especially those self-driving through Tamil Nadu, it helps to know where your vehicle comes from and how it’s linked to the state’s transport system.
