Why Morth Is Asking Licence Holders To Update Mobile Numbers Via Aadhaar

If you received an SMS asking you to “add/update and confirm” your mobile number for your driving licence through Aadhaar authentication on parivahan.gov.in, it’s part of a nationwide clean-up of transport databases to make e-services work reliably—and to cut fraud. It's not 'SPAM'. The push sits on a series of government orders that enabled contactless, Aadhaar-authenticated services for licences and vehicle registration on the Vahan–Sarathi platforms.

The legal backbone

• MoRTH’s Jan 24, 2021 order opened the door for using Aadhaar authentication to deliver “contactless service in the transport sector,” explicitly to reduce in-person visits and streamline delivery of licence/registration services. 
• Soon after, the Central Motor Vehicles (CMV) Rules were amended (Mar 31, 2021) to recognise e-authentication (including Aadhaar-based e-sign) for forms and applications filed through transport portals. This is what lets the system trust an OTP to your phone instead of a signature at the RTO counter. 
• On Sep 16, 2022, MoRTH formally notified 58 “citizen-centric” services that can be completed fully online—covering everything from learner’s licences to address changes—“with the help of Aadhaar authentication, on a voluntary basis.” A Press Information Bureau note summarised the notification the same day. 

Collectively, these measures mean the transport ecosystem is designed to run on OTP-based authentication—but OTPs only reach you if your mobile number on record is correct. That’s the immediate reason for the current SMS drive. Acko Drive reached out to senior officials at the RTO to confirm this as well.

What exactly is being asked?

The Parivahan portals now display a prominent “Update Your Mobile Number” banner for both Vahan (vehicle/RC) and Sarathi (licence/DL), guiding users to update or seed their numbers online. The workflow uses Aadhaar OTP as the trust anchor to confirm you are the rightful owner before the number is written into the database. 

MoRTH’s officials have also briefed the media that updating/confirming a mobile number—via Aadhaar authentication—is becoming a pre-requisite for availing transport and DL-related online services, aligning with the move to paperless delivery. (States are echoing this: several transport departments have begun issuing local directives making number updates compulsory for hassle-free service and timely e-challans.) 

Why it matters to consumers

You get your e-challans and alerts on time: Transport databases fuel automated services—pollution-certificate reminders, tax/insurance renewal nudges, fitness/permit alerts, and e-challans. Incorrect or missing numbers mean notices never reach you, which can snowball into higher penalties. State transport offices have flagged this as a growing problem. 

Faster online work—no counter visits: The 58 online services depend on OTPs. If the system can’t reach your phone, it often forces you back to the RTO. Keeping your number current keeps your transactions online. 

Lower risk of impersonation: Aadhaar-based OTP verification ties the update to a KYCed identity. That reduces the scope for someone else to park their number on your record and receive your OTPs. The 2021 MoRTH order was specifically aimed at secure, contactless delivery. 

Cleaner records for resale/transfer: A correct mobile number eases ownership transfer, NOCs, and address changes, now recognised under the CMV Rules through e-authentication rather than physical signatures. 

Is Aadhaar mandatory here?

The Gazette notification underpinning online services states Aadhaar authentication is voluntary for availing those contactless services. However, if you want to use the online route (rather than visiting an RTO), Aadhaar-based OTP is the standard mechanism the portals rely on—which is why the current campaign emphasises “via Aadhaar authentication.” Some states are separately directing residents to complete mobile updates to ensure e-challans and notices are delivered, but those are state-level operational mandates, not a change to the central rule that Aadhaar is voluntary for the online stack. 

How to do it

Go to parivahan.gov.in → choose Vahan (for RC) or Sarathi (for DL) → “Update Mobile Number”. You’ll be asked for basic vehicle/licence details and to authenticate via Aadhaar OTP; once verified, the new number is saved against your record. The banner and QR codes for both portals are live on the Parivahan site/

Bottom line

The message you received isn’t spam. It’s the citizen-side step of a larger Digital India upgrade inside transport services—moving everything that can be, online. The law now recognises OTP-driven, Aadhaar-authenticated filings; the services are in place; and updating your number ensures the system can actually reach you. Do it once, and most of your future licence and vehicle work should stay paperless.
