The Pollution Certificate Number (or PUC Number) is the unique serial number printed on the “Pollution Under Control” certificate issued to a vehicle. It certifies that the smoke/emission from your vehicle’s exhaust is within the permissible limits set by the government (BS4/BS6 norms).
When you ask “what is Pollution Certificate Number,” you are referring to the ID required to prove that your vehicle is eco-friendly. With fines for missing PUC hitting ₹10,000 in some states, knowing this number and its validity is critical.
What Does PUC Certificate Number Mean?
It is a central database key. When a testing center checks your car, they upload the emission data to the Parivahan server. The server returns this unique number. A handwritten PUC without a computer-generated number is invalid.
Why PUC Number is Important
- Heavy Fines: Under the amended MV Act, the fine for driving without a valid PUC is extremely high (up to ₹10,000).
- Insurance Claims: IRDAI has mandated that you must have a valid PUC number to renew your car insurance.
- Seizure: Police can seize your RC if the PUC is expired.
Where is PUC Number Used?
- mParivahan App: To show digital proof to traffic police.
- Insurance Renewal: Online insurance portals ask for this number to fetch vehicle details.
- Traffic Checks: Cameras in cities like Delhi automatically read number plates and check if the PUC number linked to that plate is expired.
