An OTP is a short numeric code sent to your registered mobile number when you try to log in or perform key actions on Parivahan. This helps secure your account and proves it’s really you trying to access the service. You usually receive the OTP by SMS on your phone. If you don’t get the OTP or it does not work, you can’t log in or complete your work.

Problems with OTPs are one of the most common login issues people face on Parivahan. They can happen on web browsers or in the mParivahan mobile app.
Why OTPs Sometimes Do Not Arrive
There are several reasons why you may not receive the OTP:
- Network problems at your end can delay or block the SMS delivery.
- Your mobile number may be wrong or not updated on the Parivahan portal.
- The server of Parivahan may be busy or slow, especially in peak hours.
- Your phone may be set to block unknown SMS, or you might have Do Not Disturb (DND) enabled for transactional messages.
- OTP delivery can fail if there are technical glitches in your browser or app.
Knowing why OTPs fail helps you fix the problem faster.
Check Your Mobile Number on Parivahan
The first thing to verify is whether the mobile number linked to your Parivahan account is correct and active. If you entered the wrong number when applying or registering, the OTP will be sent to the wrong number and you will never receive it.
If your number changed or is inactive, update it in Parivahan first. For licence-related services on Sarathi Parivahan, there is an option to update your mobile number under the “Others” section after selecting your state.
Wait and Resend Instead of Repeatedly Clicking
If you don’t receive the OTP right away, do not immediately press the “Resend OTP” button many times. Most systems take a minute or two to generate and send OTPs. Waiting patiently before requesting again increases your chance of receipt.
Sometimes high server traffic or network delays can slow down OTP delivery. If you click resend too frequently, it may confuse the system or even temporarily block further OTPs.
Make Sure Your Network Is Working Well
A good mobile network signal is essential for receiving OTPs by SMS. If your signal bars are low, try moving to a place with better coverage or switch from Wi-Fi to mobile data. Weak or unstable internet can also affect browser-based OTP pages.
If your data connection is slow, try closing other apps to free up bandwidth, or restart your phone so it reconnects to the network.
Clear Browser Cache or Try Another Browser
If you are using the Parivahan portal on a web browser and the login page hangs or does not send OTPs, the problem may be with browser cache or cookies. Clearing the cache can refresh the login page and remove old or corrupted data.
Sometimes switching to another browser like Chrome, Firefox, or Edge can solve login issues. Older or poorly configured browsers may have compatibility problems with secure sites like Parivahan.
Try a Different Device or the Mobile App
If clearing cache does not help, try logging in from a different device or the mParivahan app. Many people find that the mobile app handles OTP delivery more smoothly than the web browser, especially on phones used often for SMS.
If the app itself doesn’t show the OTP prompt or fails to receive messages, deleting and reinstalling the app can sometimes fix the login screen. Make sure you download it only from the official source like the Google Play Store or Apple App Store.
Check for DND or SMS Blocking
If you have activated Do Not Disturb (DND) on your phone, transactional SMS like OTPs may be blocked by your telecom provider. This is especially common if you enabled full DND services. Some providers allow you to enable only selective DND or transactional SMS, which ensures OTPs are delivered.
You can check your SMS settings or contact your mobile operator to make sure OTP messages are not being filtered or blocked.
Contact Support or Update Your Mobile Details at the RTO
If you have tried all the steps above and still cannot receive the OTP, it may be time to contact Parivahan support or visit your local RTO office. Some issues happen because your mobile number is not correctly linked in the government database or there are technical problems on the portal that only support can resolve.
For licence services, you may need to update your mobile number in the Sarathi database at the RTO if online options do not work. In some cases, physical presence may be required to verify identity and update details.
Tips to Prevent OTP Problems
Here are a few easy tips to avoid login problems in the future:
- Always keep your registered mobile number active and capable of receiving SMS.
- Avoid clicking “Resend OTP” repeatedly within seconds.
- Use a stable internet connection before logging in.
- Check your SMS inbox and spam folders if you have filtering apps.
- Make sure the phone’s date and time are correct, as this can affect secure login prompts.
- Update your browser or app regularly to avoid version-related glitches.
If you follow these tips, most OTP problems can be solved quickly without stress.
Conclusion
Login problems with OTP and mobile issues on the Parivahan portal are common, but they can often be fixed by checking your mobile number, waiting before resending, improving your network connection, clearing your browser cache, or using another device or the mobile app. If the issue persists, contacting support or updating your details at the RTO office can help resolve deeper problems.
With a little patience and these step-by-step fixes, you should be able to log in smoothly to Parivahan Sewa, Sarathi, or the Vahan services when you need them the most.
