A single principle underlies most of them: keeping your mobile number registered and your details consistent across documents prevents the majority of problems at the outset. Where a fix requires further detail, the relevant full guide is linked. For any issue that remains unresolved, UIDAI’s helpline 1947 is the point of escalation throughout.

OTP Not Received for Aadhaar Update: Fixes
A missing OTP almost always indicates a mobile number problem. First verify the basics: network signal, that the number is active, and that the message inbox is not full. Wait briefly and use Resend rather than requesting repeatedly. The underlying cause is usually that the number is not registered with Aadhaar, or that the SIM has been changed. A registered-mobile problem cannot be resolved online you must visit an Aadhaar centre to add or update the number, as it requires in-person verification. If the number is correct but OTPs still fail, retry after some time, as UIDAI’s system occasionally experiences delays.
Aadhaar Name Mismatch with Bank Records: Fix
A name that appears slightly differently on your Aadhaar and your bank account a missing initial, an expanded surname, or a spelling variation causes KYC and seeding to fail. The remedy is to make the two match exactly. Determine which record is incorrect: if the Aadhaar is wrong, submit a name update; if the bank record is wrong, update your bank KYC at the branch. A minor spelling correction on Aadhaar is straightforward, whereas a substantial change counts against the lifetime limit of two name changes. Once the records match, repeat the linking. The Aadhaar name-change guide covers the full update process.
Biometric Authentication Failure: What to Do
Fingerprint or iris authentication may fail owing to worn fingerprints, age, manual labour, or a substandard scanner. Retry with clean, dry hands and firm, even pressure. If it continues to fail, use an alternative: OTP-based or face authentication generally succeeds where fingerprints do not. A longer-term remedy is to update your biometrics at a centre, which refreshes the stored scans. Note that locked biometrics will also block authentication unlock them first, as covered below. Where repeated failures affect the delivery of benefits, raise the matter with the service provider, who can apply an exception mechanism.
Aadhaar Update Request Rejected: Next Steps
Rejections generally arise from a document problem: an unclear scan, a document not in your name, or details that do not match those entered. Review the rejection reason recorded against your request number, correct that specific issue a clearer colour scan, or a document that matches and submit a fresh request. Note that the processing fee may be non-refundable per attempt, so accuracy on resubmission is important. If you consider the rejection to be in error, visit an Aadhaar Seva Kendra with the original documents, or call 1947 with your URN to establish the reason for rejection.
Aadhaar Not Accepted by Bank: Resolution
Where a bank declines to accept your Aadhaar, the cause is usually straightforward to address. A name or address mismatch is the most frequent reason align the records as described above. In some cases the applicant is presenting a screenshot rather than the signed eAadhaar PDF; provide the properly signed download or a masked Aadhaar so that the QR code can be verified. A valid eAadhaar is legally equivalent to the physical card, and a bank may not refuse it merely for being digital. Where KYC linking is confused with NPCI seeding for DBT, note that these are separate steps; the bank-linking guide explains both.
Locked Aadhaar: How to Unlock
If you have locked your Aadhaar biometrics for security and authentication now fails, unlock them. On the myAadhaar portal or the Aadhaar app, open the Lock/Unlock Biometrics service, verify with an OTP, and select unlock. A temporary unlock is also available, after which the biometrics re-lock automatically. Locking affects only biometric authentication; it does not prevent OTP-based use. If you cannot unlock, confirm that your registered mobile is receiving the OTP. The biometric lock-and-unlock guide covers the full process, including the SMS method.
Incorrect Date of Birth in Aadhaar: Correction Process
A wrong date of birth requires a proof-backed correction, and it is permitted only once in a lifetime, so accuracy is essential. Submit a valid date-of-birth proof a birth certificate or passport; for applicants under 18, the birth certificate is mandatory. Certain changes can be initiated online, but date of birth is usually corrected at an Aadhaar Seva Kendra with the original document. Track the request using its reference number. Given the once-only limit, verify both the corrected date and the supporting document before submitting. The Aadhaar correction-form guide details the documents and steps.
Aadhaar Linked to Wrong Mobile Number: Fix
If your Aadhaar is linked to an old or incorrect mobile number common after a change of number every OTP will be missed, which blocks most online services. The only remedy is to update the registered mobile at an Aadhaar centre, as this cannot be done online or through the website; it requires in-person verification with biometrics. No document is required for a
mobile update, only the applicable service fee. Once updated, OTPs are delivered to the new number and online access is restored. If you are unsure which number is currently linked, the centre can confirm it, or you may check via UIDAI’s verify email/mobile service.
