Why Is DigiLocker OTP Not Coming?

DigiLocker uses OTP-based authentication linked to your Aadhaar-registered mobile number for login. If you're not receiving the OTP, you won't be able to access your digital documents. This is one of the most common DigiLocker complaints.

This guide covers all reasons why DigiLocker OTP fails and how to fix each one.

Common Reasons for OTP Failure

1. Wrong Mobile Number Linked to Aadhaar

DigiLocker sends OTP to the mobile number registered with your Aadhaar. If your current number is different from what's on Aadhaar, you won't receive the OTP.

Fix:

  • Check your Aadhaar-linked mobile at UIDAI โ†’ "Verify Mobile/Email"
  • If the number is old/wrong, update it by visiting an Aadhaar Enrolment Centre (mobile update cannot be done online)
  • Carry your Aadhaar card and the new SIM for biometric verification

2. Network or Signal Issues

Poor mobile network can delay or block SMS delivery.

Fix:

  • Ensure you have good network signal
  • Try switching between 4G/5G and 2G mode โ€” SMS sometimes works better on 2G
  • Restart your phone and try again
  • Check if your phone's SMS inbox is full โ€” delete old messages

3. DND (Do Not Disturb) Is Active

If DND is enabled on your mobile number, transactional SMS may get blocked by some carriers.

Fix:

  • Dial 1909 from your phone and disable DND
  • Or send SMS: STOP to 1909
  • Wait 24 hours for DND deactivation, then retry

4. DigiLocker Server Overload

During result seasons (CBSE, university results), DigiLocker servers face heavy traffic, causing OTP delays or failures.

Fix:

  • Wait and try after 30 minutes to 1 hour
  • Try during off-peak hours (early morning or late night)
  • Use the DigiLocker mobile app instead of the website โ€” it sometimes works better during high traffic

5. Aadhaar Not Linked to DigiLocker Account

If you're a new user trying to sign up, or your Aadhaar isn't properly linked, OTP generation itself may fail.

Fix:

  • Go to DigiLocker Sign Up and enter your Aadhaar number
  • Ensure you enter the 12-digit Aadhaar number correctly
  • The system will send OTP to your Aadhaar-linked mobile โ€” not any other number

6. OTP Expired

DigiLocker OTPs are valid for 3-5 minutes. If you enter the OTP after it expires, login will fail.

Fix:

  • Click "Resend OTP" to get a fresh code
  • Enter the OTP as soon as you receive it
  • Don't request multiple OTPs rapidly โ€” wait for one to arrive first

Step-by-Step Fix Process

Step 1: Verify Your Aadhaar Mobile Number

  1. Visit UIDAI portal
  2. Click "My Aadhaar" โ†’ "Verify Mobile/Email"
  3. Enter your Aadhaar number and the mobile number you think is linked
  4. It will confirm if the number matches or not

Step 2: Check SMS and Network

  1. Ask someone to send you a regular SMS โ€” confirm SMS is working
  2. Check if your inbox is full (some phones block new SMS when storage is full)
  3. Disable DND by calling 1909
  4. Restart your phone

Step 3: Try Alternative Login Methods

  1. Use the DigiLocker app โ€” download from Google Play Store or Apple App Store
  2. Try "Sign in with Aadhaar" option instead of mobile number
  3. If you had set a username/password previously, use that to log in

Step 4: Clear Browser Cache (If Using Website)

  1. Open your browser settings
  2. Clear cache and cookies
  3. Try in Incognito/Private mode
  4. Use a different browser (Chrome, Firefox, Edge)

Step 5: Wait and Retry

If it's a server-side issue:

  1. Wait 30-60 minutes
  2. Check DigiLocker Twitter for any downtime announcements
  3. Try during non-peak hours โ€” early morning (6-8 AM) works best

Step 6: Contact DigiLocker Support

If nothing works:

  1. Email: support@digilocker.gov.in
  2. Call DigiLocker helpline (check the official website for current number)
  3. Raise a ticket on the DigiLocker portal under "Help" section
  4. Include your Aadhaar number (masked) and describe the exact error message

If You've Changed Your Mobile Number

If you no longer have access to your Aadhaar-linked number:

  1. Visit the nearest Aadhaar Enrolment Centre
  2. Carry: Aadhaar card + new SIM card (active) + any ID proof
  3. Request mobile number update โ€” requires biometric verification
  4. Processing time: 5-10 working days
  5. Once updated, DigiLocker OTP will come to your new number

Book an appointment at appointments.uidai.gov.in to avoid long queues.

Important Tips

  1. Always keep your Aadhaar mobile number active โ€” don't let the SIM expire
  2. Don't click Resend OTP repeatedly โ€” wait at least 60 seconds between attempts
  3. During CBSE result season, expect delays โ€” try early morning
  4. The DigiLocker app is generally more reliable than the website for OTP delivery
  5. Save your DigiLocker username and password as a backup login method

Frequently Asked Questions

Q1. DigiLocker OTP goes to my old number. How do I change it?

DigiLocker OTP is sent to your Aadhaar-linked mobile number. To change it, update your mobile number in Aadhaar by visiting an Aadhaar Enrolment Centre with biometric verification.

Q2. How many times can I request OTP resend?

You can request OTP resend multiple times, but there may be a cooldown period. If you exceed the limit, you'll be temporarily blocked โ€” wait 30 minutes and try again.

Q3. Can I log into DigiLocker without OTP?

Yes, if you've set up a username and password during registration. Use the "Sign in with Username" option. You can also use the Aadhaar-based sign-in.

Q4. DigiLocker shows "Technical Error" during login. What do I do?

This usually means the server is overloaded. Clear browser cache, try incognito mode, or switch to the mobile app. If it persists, try after a few hours.

Q5. Is DigiLocker OTP different from Aadhaar OTP?

They use the same system. DigiLocker authentication goes through UIDAI's OTP service, so the OTP is sent by UIDAI to your Aadhaar-linked mobile.

Q6. OTP is coming but DigiLocker says "Invalid OTP". Why?

The OTP may have expired (valid for 3-5 minutes), or you may be entering an old OTP. Click Resend, wait for the new OTP, and enter it immediately.

Q7. Can I use DigiLocker with a non-Aadhaar mobile number?

No. DigiLocker requires Aadhaar-based authentication. Your login mobile number must be the one linked to your Aadhaar. There's no way to use a different number.
