An Aadhaar number follows you into almost every important transaction in India: opening a bank account, claiming a subsidy, filing tax, buying a SIM, registering property, applying to college. Which means one outdated line on it, whether an old address, a surname you changed after marriage, or a mobile number you stopped using three years ago, quietly breaks things you did not expect it to break.
The good news is that an Aadhaar card update online is genuinely straightforward for most changes, takes a few minutes, and does not require standing in a queue. This guide covers exactly what you can change from home, what still needs a visit, the documents accepted, how to track your request, and the mistakes that get updates rejected.
What Is an Aadhaar Card Update and When Do You Need One?
An Aadhaar update is a request to the Unique Identification Authority of India (UIDAI) to correct or refresh the information linked to your 12-digit number. It falls into two broad buckets:
- Demographic update: name, date of birth, gender, address, mobile number, email or language.
- Biometric update: fingerprints, iris scan and photograph.
You typically need one after moving house, marriage, a legal name change, discovering a spelling error, when your registered mobile number changes, or when a child crosses the ages at which biometrics must be re-captured.
Aadhaar Card Update Online: What You Can and Cannot Change From Home
Address changes and document re-verification can be completed entirely online through the myAadhaar portal, while mobile number, email and all biometric updates require an in-person visit to an Aadhaar Seva Kendra.
| What you want to change | Can it be done online? |
|---|---|
| Address | Yes, with a valid proof of address |
| Name (spelling correction or legal change) | Sometimes; availability on the portal has changed over time, otherwise at a centre |
| Date of birth | Sometimes online with valid proof; often requires a centre visit |
| Gender | Sometimes online; often requires a centre visit |
| Document update (re-uploading PoI and PoA) | Yes |
| Mobile number | No, centre visit required |
| Email address | No, centre visit required |
| Fingerprints, iris, photograph | No, centre visit required |
UIDAI has repeatedly adjusted which demographic fields are available for self-service online. Before assuming a field is closed to you, log in and check what the portal currently offers.
How to Update Aadhaar Card Online: Step-by-Step
Everything below assumes one thing: your current mobile number is already registered with Aadhaar, because every online action is authenticated with an OTP sent to that number. If it is not, skip ahead to the mobile number section first.
Updating your address online
- Go to the official myAadhaar portal at myaadhaar.uidai.gov.in. Only use the UIDAI domain, because there are many lookalike sites charging for a free service.
- Click Login, enter your 12-digit Aadhaar number and the captcha.
- Enter the OTP sent to your registered mobile number.
- Select Update Aadhaar Online, then choose Address.
- Enter the new address exactly as it appears on your proof document. Mismatches are the single biggest cause of rejection.
- Upload a scanned copy of a valid proof of address. Keep it clear, complete and within the size limits shown.
- Pay the applicable fee online if one is charged, and submit.
- Save the Update Request Number (URN) or acknowledgement slip. You need it to track the request.
The free document update
UIDAI runs a document update facility that lets holders re-upload current proof of identity and proof of address to refresh records, particularly for Aadhaar numbers issued many years ago. This has been offered free of charge through myAadhaar for extended periods, with the deadline pushed back several times. Because the cut-off date has moved repeatedly, check the current deadline on the portal rather than relying on an older news report.
Documents Accepted for an Aadhaar Update
UIDAI publishes a detailed list of acceptable documents. Commonly accepted options include:
- Proof of Identity: passport, PAN card, voter ID, driving licence, ration card, government photo ID card, marksheet from a recognised board or university.
- Proof of Address: passport, bank passbook or statement, electricity, water, gas or telephone bill not older than the permitted period, rent agreement registered with the state, voter ID, driving licence, property tax receipt.
- Proof of Date of Birth: birth certificate, passport, or a recognised board marksheet. Note that UIDAI has clarified Aadhaar itself is not a proof of date of birth.
- Proof of Relationship: for address updates based on a family head’s document.
Upload the full document, all pages if the address spans more than one, and make sure the name matches your Aadhaar name character for character.
How to Update Your Mobile Number in Aadhaar
This one genuinely cannot be done from home, and that restriction exists for a sensible reason: if a mobile number could be changed remotely, anyone who compromised your account could take over every OTP you receive.
- Locate your nearest Aadhaar Seva Kendra or enrolment centre using the UIDAI website’s centre locator.
- Book an appointment online where the option is available, or walk in.
- Carry your Aadhaar card or a printout. No supporting document is required for a mobile number update.
- Fill the Aadhaar update form with the new number.
- Give your biometric authentication (fingerprint) at the counter.
- Pay the prescribed fee and collect the acknowledgement slip containing your URN.
The number usually becomes active for OTP purposes within a few days. Once it is live, everything else on this page becomes possible from your sofa.
Aadhaar Update Status Check
To track a submitted request, visit the myAadhaar portal and use the Check Enrolment & Update Status option, entering your URN or the enrolment ID from your acknowledgement slip along with the captcha.
Requests are typically processed within a couple of weeks, though timelines vary with verification load. Once approved, download the updated e-Aadhaar as a password-protected PDF. The password is the first four letters of your name in capitals followed by your year of birth. For example, a person named Rahul born in 1996 would use RAHU1996.
Aadhaar Update Fees and Lifetime Limits
UIDAI charges a modest prescribed fee for demographic updates and a separate fee for biometric updates, with certain categories such as the mandatory children’s biometric update exempted when done within the eligible age window. Fee amounts have been revised periodically, so confirm the current schedule on the UIDAI website or at the centre rather than relying on figures quoted in older articles.
There are also lifetime limits designed to prevent identity churn. Broadly, name changes are permitted a limited number of times, and date of birth and gender changes are generally allowed only once. Exceeding a limit does not make a change impossible, but it requires an exception request routed through UIDAI’s regional office with supporting evidence.
Mandatory Biometric Update for Children
Children enrolled below the age of five receive an Aadhaar without fingerprint and iris data, since those biometrics are not yet stable. Two Mandatory Biometric Updates (MBU) are therefore required as the child grows, and these are free when completed within the prescribed age windows. Missing them can lead to the Aadhaar being deactivated for authentication purposes, which surfaces at the worst possible moment, such as a school admission or a scholarship application.
Why Aadhaar Updates Get Rejected
Most rejections come down to a small set of avoidable problems:
- The name or address on the uploaded document does not match what was typed in the form.
- The scan is blurred, cropped, or missing a page.
- The document is not on UIDAI’s accepted list, or is older than the permitted validity for a utility bill.
- Abbreviations and expansions are inconsistent, such as writing Rd. in the form where the document says Road.
- A self-attested copy was uploaded without the required signature.
If a request is rejected, you can correct the issue and file a fresh one. Fees are generally not refunded, so it is worth being pedantic the first time.
Keeping Your Aadhaar Safe
Two habits are worth adopting. First, use a Masked Aadhaar download whenever you have to share a copy, since it hides the first eight digits while remaining a valid document. Second, consider locking your biometrics through myAadhaar when you are not actively using them, and unlocking only when needed. Never share your Aadhaar OTP with anyone, including callers claiming to be from a bank or from UIDAI itself. UIDAI does not ask for OTPs over the phone.
Frequently Asked Questions
How long does an Aadhaar card update take?
Most updates are processed within about 7 to 15 days of submission, though this can extend during periods of high volume. You can track progress with your URN on the myAadhaar portal.
Can I update my Aadhaar address online without proof of address?
Generally no. A valid proof of address is required. Where you live at an address held in a family member’s name, UIDAI provides a head-of-family route requiring a proof of relationship document and the family head’s consent.
Is the Aadhaar card update online free?
The document re-upload facility on myAadhaar has been free during extended promotional windows. Standard demographic and biometric updates carry a prescribed fee. Check the portal for current charges.
Can I change my mobile number in Aadhaar online?
No. Mobile number and email updates require biometric authentication in person at an Aadhaar Seva Kendra or enrolment centre.
What is the password for the e-Aadhaar PDF?
It is the first four letters of your name in capital letters followed by your four-digit year of birth, as printed on your Aadhaar.
How many times can I change my name in Aadhaar?
Name changes are subject to a lifetime cap, with date of birth and gender generally changeable only once. Beyond the limit, an exception must be approved by UIDAI’s regional office with supporting documents.
Conclusion
An Aadhaar card update online is one of those chores that takes fifteen minutes and saves days of trouble later. Keep the address current, make sure the mobile number linked to it is one you still use, and re-upload your identity documents if your Aadhaar dates back many years.
Do it through the official UIDAI portal only, match your documents word for word, and hold on to the URN until the change shows up. If your Aadhaar feeds into government benefit transfers, this is doubly worth doing.
