What Is Aadhaar Update or Correction?
Aadhaar update (also called Aadhaar correction) means modifying existing demographic details stored in UIDAI records.
It does not generate a new Aadhaar number.
Aadhaar updates are typically required when:
- Personal details were entered incorrectly during enrolment
- Information has changed over time
- Linked services fail due to data mismatch
Updating Aadhaar ensures your details remain valid, verifiable, and usable across services.
When Is Aadhaar Update Required?
You should update Aadhaar if:
- Your address has changed
- Your mobile number is no longer active
- Your name spelling is incorrect
- Your date of birth is wrong
- OTP is not received due to outdated mobile number
- Aadhaar download or verification keeps failing
See Aadhaar OTP problems.

How Aadhaar Update Affects Download & OTP Services
While an Aadhaar update request is under processing:
- OTP may fail or be delayed
- Aadhaar download may be blocked
- e-Aadhaar PDF may not generate
See Aadhaar download by Aadhaar number.
This is temporary and resolves once update is approved.
Aadhaar Update Status – How to Check Properly
After submitting an update request:
- Status can be tracked online
- Approval may take several working days
See how to check Aadhaar update status.
Do not submit multiple update requests unless required.
Common Aadhaar Update Problems & Mistakes
- Submitting unclear documents
- Repeated update attempts
- Mismatch between documents and Aadhaar data
- Trying online update for mobile number
- Expecting instant approval
Understanding the process prevents delays.
Can Aadhaar Be Updated Without OTP?
- Online updates → OTP mandatory
- Offline updates → OTP not required (biometric used)
OTP is always tied to online identity verification.
