If your Aadhaar has errors in your name, address, date of birth, gender, or mobile number, you can correct them online through the myAadhaar portal (myaadhaar.uidai.gov.in) or by visiting an Aadhaar Enrolment Centre. To link Aadhaar with your PAN, bank account, or mobile number, follow the specific linking process for each service — all of which can now be done online. Under the Aadhaar Act, 2016, every resident of India is entitled to obtain an Aadhaar number (Section 3), and the government can require Aadhaar authentication for subsidies and certain services (Section 7). Keeping your Aadhaar accurate and linked is essential because incorrect details can block access to government benefits, bank accounts, and tax filings.
Why this matters
Aadhaar is India's most widely used identity document — over 140 crore (1.4 billion) residents have an Aadhaar number. It is linked to bank accounts for direct benefit transfers (DBT), required for filing income tax returns (PAN-Aadhaar linking), and used for authentication in telecom, banking, and government services. A simple error in your name spelling, an outdated address, or an unlinked mobile number can cause real problems: your subsidies may stop, your bank account may be frozen for KYC non-compliance, or your income tax return may be invalidated. Fixing these issues early prevents cascading problems.
Step-by-step: How to fix common Aadhaar issues
1. Update name, address, date of birth, or gender online
Online process (through myAadhaar portal):
- Visit myaadhaar.uidai.gov.in
- Log in with your Aadhaar number and OTP sent to your registered mobile number
- Click "Document Update" or "Update Aadhaar Details"
- Select the field you want to update (name, address, DOB, gender)
- Upload the supporting document (scanned copy, max 2MB, JPEG/PDF format)
- Submit and note the Service Request Number (SRN)
- Track the update status using the SRN
Accepted documents for updates:
- Name: Passport, PAN card, voter ID, driving licence, birth certificate
- Address: Passport, bank statement (last 3 months), utility bill (last 3 months), voter ID, registered rent agreement, gas connection bill
- Date of birth: Birth certificate, SSLC/10th class mark sheet, passport
- Gender: Any government-issued ID showing the correct gender
Important: Online Aadhaar updates are free until June 14, 2026. After this date, UIDAI may charge a nominal fee. Currently, biometric updates (photo, fingerprints, iris) can only be done at an Aadhaar Enrolment Centre, not online.
2. Update your mobile number
Your Aadhaar-linked mobile number cannot be changed online — it must be done in person at an Aadhaar Enrolment Centre because mobile number changes require biometric authentication.
Process:
- Visit the nearest Aadhaar Enrolment Centre (find one at appointments.uidai.gov.in)
- Carry your Aadhaar card (or e-Aadhaar) and the SIM card of your new mobile number
- Fill in the Aadhaar Update Form and select "Mobile Number Update"
- Provide biometric authentication (fingerprint or iris scan)
- An OTP will be sent to your new number for verification
- Receive the acknowledgment slip with Update Request Number (URN)
In practice: The update takes 10-30 days. You can track it at myaadhaar.uidai.gov.in using the URN. There is no charge for updating the mobile number.
3. Link Aadhaar to PAN
Aadhaar-PAN linking is mandatory under Section 139AA of the Income Tax Act, 1961. Without linking, your PAN becomes inoperative — you cannot file returns, claim refunds, or complete certain financial transactions.
Online process:
- Visit incometax.gov.in/iec/foportal/
- Click "Link Aadhaar" under Quick Links
- Enter your PAN number, Aadhaar number, and name as per Aadhaar
- Click "Link Aadhaar"
- Pay the fee (Rs 1,000 as of 2026) if you missed previous deadlines
- Confirm by checking status at the same portal
Via SMS: Send UIDPAN [space] [12-digit Aadhaar] [space] [10-digit PAN] to 567678 or 56161
In practice: If there is a name mismatch between your PAN and Aadhaar, the linking will fail. Correct the name in either PAN (through the NSDL/Protean portal) or Aadhaar (through myAadhaar) to make them match, then retry.
4. Link Aadhaar to bank account
Process:
- Visit your bank branch with your Aadhaar card and bank passbook/account details
- Fill in the Aadhaar Seeding Form available at the branch
- Alternatively, link online through your bank's net banking or mobile banking app (most banks offer this under "Profile" or "Aadhaar Linking")
- Some banks accept linking via SMS — send ADHAR [space] [Aadhaar number] [space] [Account number] to the bank's designated number
In practice: Aadhaar-bank linking is essential for receiving DBT (Direct Benefit Transfer) payments, including LPG subsidies, MGNREGA wages, and PM-KISAN payments. Without linking, your subsidies may be diverted to the wrong account or stopped entirely.
5. Link Aadhaar to mobile number
Process:
- Visit the nearest store of your telecom provider (Jio, Airtel, Vi, BSNL) with your Aadhaar card
- Complete biometric verification (fingerprint or iris scan) at the store
- The re-verification is typically completed on the spot
In practice: Following the Supreme Court's judgment in K.S. Puttaswamy v. Union of India (2018), Aadhaar-mobile linking is no longer mandatory for existing SIM cards. However, many telecom providers still use Aadhaar-based eKYC for new SIM activations as it is the simplest method.
What if things go wrong
If the online update is rejected
The UIDAI quality team may reject your update if the uploaded document is unclear, the information does not match the document, or the document is not from the accepted list. Visit an Aadhaar Enrolment Centre in person with original documents for manual verification and update.
If someone else has linked their Aadhaar to your bank account
This can happen due to data entry errors. Contact your bank immediately and request de-linking. File a complaint with the bank's grievance cell and, if unresolved, with the Banking Ombudsman (rbi.org.in/scripts/Complaints.aspx).
If your biometrics fail at the Enrolment Centre
Biometric failures are common among elderly persons and manual labourers (worn fingerprints). Request an iris scan as an alternative. If both fail, the Enrolment Centre operator can escalate the case to the UIDAI regional office for manual processing.
If someone misuses your Aadhaar
Lock your Aadhaar biometrics immediately through the myAadhaar portal (myaadhaar.uidai.gov.in > "Lock/Unlock Biometrics"). File a complaint with the UIDAI helpline (1947) and the cyber crime portal (cybercrime.gov.in). Under Section 31 of the Aadhaar Act, impersonation by using another person's Aadhaar is punishable with imprisonment up to 3 years and a fine of up to Rs 10,000.

Common myths
Myth: Aadhaar is mandatory for everything. Reality: The Supreme Court in K.S. Puttaswamy v. Union of India (2018) limited mandatory Aadhaar to government subsidies under Section 7 of the Aadhaar Act and income tax filing. It struck down mandatory Aadhaar for bank accounts and mobile phones. However, Aadhaar remains the easiest KYC option for most services, so most people voluntarily link it.
Myth: If someone has your Aadhaar number, they can steal your money. Reality: Your Aadhaar number alone is not sufficient for any financial transaction. Authentication requires biometric verification (fingerprint/iris) or OTP to your registered mobile number. Lock your biometrics when not in use for additional security.
Myth: You can update Aadhaar details as many times as you want. Reality: You can update your address multiple times, but name and date of birth can be updated a limited number of times (name: up to 2 times, DOB: once). Choose carefully when making these changes.
Myth: If your Aadhaar has an error, your government benefits will automatically stop. Reality: Minor errors (spelling variations) may not immediately affect benefits. However, significant errors (wrong date of birth, gender) can cause authentication failures. Fix errors proactively rather than waiting for a problem.

Frequently asked questions
How long does an Aadhaar update take? Online updates typically take 10-30 days. Updates done at an Enrolment Centre take 10-30 days as well. You can track the status using the SRN or URN on the myAadhaar portal.
Is there a fee for Aadhaar updates? Online document updates are currently free (until June 14, 2026). At Enrolment Centres, demographic updates (name, address, DOB, gender) cost Rs 50, and biometric updates (photo, fingerprints, iris) also cost Rs 50.
What if my Aadhaar address is different from my current address? You can update your address online or at an Enrolment Centre. Alternatively, UIDAI offers an "Address Validation Letter" system — if you do not have address proof in your name, a family member (head of family) can validate your address request.
Can I have two Aadhaar numbers? No. Aadhaar is a unique identity — each person can have only one Aadhaar number. If you accidentally enrolled twice, contact UIDAI at 1947 to deactivate the duplicate.
