How to Update Mobile Number in Parivahan Online: Complete 2026 Guide

Updating your mobile number on the Parivahan portal ensures you receive critical e-challan alerts, RC/DL renewal reminders, and service notifications without RTO visits. The process works for Vahan (vehicle RC) and Sarathi (DL/LL) portals, using OTP verification on your new number—free, instant, and Aadhaar-optional in most states.​

Why Update Matters Now

Outdated numbers block online services like RC downloads, Fastag recharges, and court challan payments. With 2026’s mandatory digital compliance, linked mobiles get real-time SMS for BS7 emissions tests and EV subsidies. Non-updates risk fines during police checks or insurance claims.​

Prerequisites Checklist

• Vehicle Registration Number (RC) or DL/LL application number
• Old registered mobile (for OTP, if linked)
• New Indian mobile number (+91 format)
• Aadhaar number (some states require)
• No fees charged; documents rarely needed online

Step-by-Step: Update Mobile in Vahan (RC/Vehicle)

1. Visit https://vahan.parivahan.gov.in > Select your state > “Vehicle Related Services.”
2. Click “Other Services” > “Update User Mobile No.”
3. Enter Registration Number + old mobile > Generate OTP (sent to old number).
4. Verify OTP > Enter new mobile number > Submit.
5. Success screen shows Application Reference Number (ARN)—save for status check.​

Alternative without old number: Use chassis/engine number from RC > Aadhaar verification route.

Step-by-Step: Update Mobile in Sarathi (DL/LL)

1. Go to https://sarathi.parivahan.gov.in > Select state.
2. New user? Register first. Existing: Login > “Others” > “Mobile Number Update.”
3. Enter DL number (15/16-digit) or LL application number + Aadhaar-linked mobile.
4. OTP to Aadhaar mobile > Confirm new number > Update complete.​​

Track Update Status

• Back to Parivahan > “Application Status” > Enter ARN.
• Shows “Approved” in 24-48 hours; new number activates instantly for OTPs.​

Troubleshooting Common Issues

Issue	Solution
“Invalid Reg No”	Check RC for exact format (e.g., MH12AB1234); retry after 5 mins.
No OTP on old number	Use “Forgot Mobile” > Chassis no. + Aadhaar OTP.
Aadhaar mismatch	Visit RTO with Form 2 + proof (free, 1-day process).
DL shows 16 digits?	Enter first 15; ignore last check digit.
Multiple vehicles	Update once—links to all under same owner.

Offline fallback: RTO visit with RC original, new SIM proof, Form 35 (₹50-200 fee).​
