Quick Answer: You do an RC mobile number update online on Vahan's mobile-update service, vahan.parivahan.gov.in/mobileupdate, with an Aadhaar OTP. Enter your registration number, full chassis and engine numbers and the registration dates, then confirm the OTP sent to your Aadhaar-registered mobile. If your RC name doesn't match Aadhaar, the RTO verifies and approves it instead.
To update mobile number in RC records, you usually don't need to visit the Regional Transport Office (RTO). The Ministry of Road Transport and Highways (MoRTH) runs the service on Vahan, the national vehicle registration database, and you need only your RC and your Aadhaar-linked phone.

Short on time and don't want to chase an RTO agent online or offline? Jaagruk Bharat's team can link Aadhaar to your RC for you, which Vahan's Aadhaar-OTP services rely on; the help box sits right after the Vahan steps.
Why should the mobile number on your RC be up to date?
Because Vahan sends every OTP for your vehicle to that number. MoRTH urges all registered vehicle owners, on the Parivahan Sewa portal, to keep the mobile number in Vahan updated so their records stay complete, accurate and current.
The national e-challan portal, for example, can verify you with an OTP sent to the mobile number registered at Vahan before you pay a fine. Ownership transfers, address changes and other RC services also rely on OTPs to that number.
How do you change the mobile number on your RC through Vahan with an Aadhaar OTP?
Vahan mobile number update happens on MoRTH's official mobile-update page, and an OTP to your Aadhaar-registered mobile confirms it. To update RC mobile number online, keep your RC nearby, because the form asks for full numbers, not the last few digits.
- Open the Vahan mobile-update service ("Application for Mobile number updation").
- Enter the vehicle registration number, exactly as printed on your RC.
- Enter the full chassis number and the full engine number. Both are printed on your RC.
- Add the registration date and the registration valid-up-to date. Commercial vehicles enter the fitness valid-up-to date instead.
- Type the captcha and tap Validate.
- Enter the OTP sent to your Aadhaar-registered mobile and validate it.
- Submit the application and save the acknowledgement the portal shows.
The Parivahan mobile number update link on the parivahan.gov.in homepage opens this same page. There's no PDF form to download: you fill everything on Vahan. Owners in states such as Maharashtra and Haryana use the same national Vahan service for an RC mobile number update. A few states run their own transport portals, so check yours if Vahan can't find your vehicle.
Get it done for you
- We link Aadhaar with your vehicle RC online, so Vahan's Aadhaar-OTP services work for you.
- Our team guides you over WhatsApp through the details Vahan asks for.
- We track the request and share the confirmation with you.
How do you update it if your RC name does not match Aadhaar?
You pick an RTO on the same form, upload the documents it asks for, and that RTO verifies and approves the change. Vahan shows this option when the name in its database and the name in your Aadhaar information don't match.
- Fill the form and validate the Aadhaar OTP as above.
- Read the mismatch note, then choose the RTO where you want the application submitted.
- Upload the required documents and submit.
- Follow up with that RTO, which carries out the physical verification and approval.
Vahan citizen services also carry a separate Update Mobile Number page where verification and approval are done at the RTO. It asks for the same vehicle details. If you don't have complete information, Vahan's own advice is to visit the RTO to get the details updated.
How do you check whether the update went through?
Use "Know Your Application Status" on the Vahan mobile-update page, or the same option under Vahan's citizen services. The RC mobile number update status there tells you whether the request is pending, with the RTO or done.
Once your RC mobile number update is approved, the next Vahan OTP should reach your new number. You can also open your virtual RC in mParivahan: our guide on how to download your virtual RC on mParivahan shows the steps.
Does updating your RC mobile number cost anything?
Parivahan doesn't list a separate government fee for an RC mobile number update, and the Aadhaar-OTP form on Vahan has no payment step. So on the official route, RC mobile number update charges shouldn't come up.
If the RTO-verified route in your state shows a charge, the portal displays it before you pay. An assisted service charges its own fee, also shown upfront.
Is updating your RC mobile number the same as linking Aadhaar to your RC?
Not quite. To link RC with Aadhaar number online, you use Aadhaar authentication on the Parivahan Vahan portal, which MoRTH made voluntary for its online vehicle services, and how it works can vary by state.
A mobile number update only changes the contact number on your vehicle record. It uses your Aadhaar OTP to prove it's you, but that isn't the same job as linking Aadhaar to the RC. For that, follow our step-by-step guide on how to link Aadhaar with your RC, or use the "Get it done for you" box above.
Should you change the number on your driving licence at the same time?
Yes, if your driving licence carries the same old number. Your licence sits on Sarathi, a separate Parivahan database, so a Vahan update doesn't change it. Sarathi has its own mobile-number update service, also listed on parivahan.gov.in.
