In India, each Assam RTO code (which starts with the state identifier AS) is a unique vehicle registration prefix that shows the district or Regional Transport Office where a vehicle was registered — for example, AS-01 represents one of the RTOs in Assam, and every vehicle number plate in the state begins with this Assam RTO code list prefix.
In Assam, RTO codes aren't just for districts; some codes are reserved for specific entities like the Assam State Transport Corporation (ASTC) and the Assam Police.

It helps establish legal ownership, ensures compliance with motor vehicle laws, and allows vehicles to be lawfully driven on public roads in Assam.
You can apply for a permanent Registration Certificate (RC) in Assam through your nearest RTO office or via the Parivahan Sewa portal. The process is regulated by the Transport Department and must be completed after purchasing a new vehicle.
Visit the AS RTO or Apply Online
You can apply online through the Parivahan Sewa portal by selecting “Vehicle Related Services” and choosing Assam and your concerned RTO. Alternatively, you may visit the nearest Assam RTO office in person with all required documents.
Fill and Submit Application Form
Fill and submit Form 20, which is the application for vehicle registration. If the dealer has not registered the vehicle, the owner must apply within 7 days of purchase.
Document Verification and Vehicle Inspection
RTO officials will verify the submitted documents and inspect the vehicle to confirm chassis and engine details. This step ensures that the vehicle meets legal and safety standards.
Payment of Fees and Taxes
Pay the applicable registration fees and road tax as prescribed by the Assam Transport Department.
Issue of Registration Certificate
After successful verification and payment, the permanent RC is issued. It is usually provided in smart card or digital format.
To apply for a permanent Registration Certificate, you will need the following documents:
Form 20 – Application for Registration Certificate
Form 21 – Sale Certificate from the dealer
Form 22 – Roadworthiness Certificate from the manufacturer
Valid Motor Insurance Certificate
Proof of Address (Aadhaar card, passport, utility bill, etc.)
Proof of Identity (Aadhaar card, PAN card, etc.)
Vehicle Invoice or Purchase Receipt
Road Tax and Registration Fee Payment Receipt
Vehicle registration should be completed within the prescribed time after purchase to avoid penalties.
You can track the status of your RC application online through the Parivahan Sewa portal.
The RC serves as the official proof of vehicle ownership and is required for insurance, resale, and legal purposes.
Renewing the Registration Certificate (RC) in Assam RTO is necessary once the validity of your vehicle’s registration expires, to continue using it legally on public roads. The renewal process ensures that your vehicle remains roadworthy and compliant with transport regulations in Assam.
For private vehicles, the RC is valid for 15 years from the date of first registration and can be renewed thereafter for 5 years at a time. For commercial vehicles, the validity is usually shorter and depends on permit conditions.
To renew your RC, you need Form 25 (Application for Renewal of Registration), the original Registration Certificate, valid motor insurance, Pollution Under Control (PUC) certificate, road tax payment receipt (if applicable), address proof, identity proof, prescribed renewal fee receipt, and the vehicle for physical inspection at the RTO.
You can check your Registration Certificate (RC) status in Assam easily online through the official government portal, without visiting the RTO. This service is managed by Parivahan Sewa under the Ministry of Road Transport and Highways.
