Aadhaar Mobile Number Update – Complete UIDAI Process

Updating your mobile number in Aadhaar is essential for receiving OTPs and accessing online Aadhaar services such as Aadhaar download, e-Aadhaar PDF, verification, and updates.

If the mobile number linked with Aadhaar is inactive, lost, or incorrect, OTP-based services will stop working completely.

This guide explains how Aadhaar mobile number update works, why it cannot be done online, what documents are required, how long it takes, and how to check update status after submission.

What Is Aadhaar Mobile Number Update?

Aadhaar mobile number update means linking a new or correct mobile number with your existing Aadhaar record in UIDAI's database.

Key points:

  • Aadhaar number remains the same
  • Only the mobile number is updated
  • OTP services start working after approval
  • Biometric verification is mandatory

When Do You Need to Update Mobile Number in Aadhaar?

You should update your mobile number if:

  • Old mobile number is lost or deactivated
  • OTP is not received during Aadhaar services
  • Mobile number was never linked earlier
  • Aadhaar download or verification keeps failing

See Aadhaar OTP problems.

Can Aadhaar Mobile Number Be Updated Online?

No.

UIDAI does not allow mobile number update online.

Reasons:

  • Mobile number controls OTP-based identity verification
  • UIDAI requires biometric authentication
  • Prevents unauthorised changes

All mobile number updates must be done offline at an Aadhaar Seva Kendra.
