The URN is issued at the Aadhaar Seva Kendra, not generated online.
Visit the UIDAI website.

On the myAadhaar page, click Check Enrolment & Update Status.
Select URN (Update Request Number).
Enter your URN and the captcha code, then click Submit.

Verifying a mobile number through the UIDAI portal only confirms whether a mobile number is already linked to Aadhaar. It does not show the status of an ongoing or recently submitted update request. For update-related tracking, users must rely on the URN status check.
Visit the UIDAI website.
Find "My Aadhaar" and click on the "Verify Email/ Mobile Number".
Select the "Verify Mobile Number" option. Enter the Aadhaar number, mobile number, and captcha code, then click "Submit".
The status of your mobile number verification with UIDAI records will be shown as you click submit.
Note: Successful verification confirms only that the mobile number is linked. It does not indicate whether an Aadhaar update request is under review, approved, or rejected.
Here are a few must-knows after you update your Aadhaar card number with your mobile number:
Updating your mobile number doesn’t require reprinting your Aadhaar - the number is linked in UIDAI records, not printed on the card.
Aadhaar mobile number updates are usually completed within 7–30 days. Different Aadhaar-enabled services may reflect the update at different speeds, so a short delay is normal.
Once the update is approved, you will receive SMS confirmation on the newly registered mobile number. No physical Aadhaar letter or card is sent for a mobile number update.
You’ll receive a URN (Update Request Number) on your acknowledgement slip - use it to check update status on the UIDAI portal.
From authentication to online address updates, your new number will receive all Aadhaar-linked OTPs.
After updating Aadhaar, you’ll need to update your mobile number separately with banks, PAN, insurance, or government portals (they don’t sync automatically).
If your number is deactivated, you won’t receive OTPs for Aadhaar verification or e-KYC.
UIDAI allows only one mobile number to be active per Aadhaar — the old number (if any) gets de-linked.
If your mobile number update does not reflect even after 30 days, contact the UIDAI helpline at 1947 for assistance.
If your Aadhaar-linked mobile number is inactive, lost, or outdated, it can lead to several practical issues. Since most Aadhaar services rely on OTP-based authentication, an incorrect mobile number may restrict access to essential services and benefits.
You will be unable to complete OTP authentication for Aadhaar-related online services.
Services and schemes that rely on Aadhaar OTP verification—such as LPG subsidy, PM-KISAN, and other DBT schemes—may face delays or failures.
Without access to the registered mobile number, OTP-based PAN–Aadhaar linking and verification can become difficult.
Aadhaar-linked platforms like DigiLocker and UMANG may not function properly without OTP access.
Banks, insurers, and financial institutions depend on Aadhaar OTPs for e-KYC and verification.
You will miss important SMS notifications related to Aadhaar authentication, updates, or security alerts.
Services such as online address updates or Aadhaar authentication checks cannot be completed without OTP access.
Without SMS alerts, unauthorised Aadhaar authentication attempts may go undetected.
