With increasing traffic regulations and emission-based restrictions across India, it has become important for vehicle owners to know whether their car is BS4 or BS6 compliant. One of the easiest, fastest, and most reliable ways to check this is through the VAHAN portal or the mParivahan mobile app, both managed by the Government of India. You can check whether your car is BS4 or BS6 compliant by entering your vehicle registration number on the VAHAN portal or mParivahan app. The emission norm (BS-IV or BS-VI) is displayed instantly from the official government database. This is the most accurate and legally valid method in India.
This guide explains exactly how to check your vehicle’s emission norm online using your registration number.
What Are BS4 and BS6 Emission Norms?
Before we get into the steps, here’s a quick overview:
- BS4 (Bharat Stage IV): Vehicles registered before 1 April 2020
- BS6 (Bharat Stage VI): Vehicles registered on or after 1 April 2020
BS6 norms are stricter and designed to reduce air pollution by limiting harmful emissions.
Why Use VAHAN or mParivahan to Check BS4 or BS6?
The VAHAN database is India’s official vehicle registry. Any information shown here is:
- Government-verified
- Legally valid
- Updated as per your vehicle’s registration
This makes it more reliable than dealer claims or assumptions based on model year.
