Dear friend,
You can easily update any information like Name, Address, DOB, Father's Name, etc. through Aadhar Self Service Update Portal only if you have correct mobile number registered on your Aadhar Card. If the appropriate mobile number is registered in your Aadhar Card, then an OTP will be generated on your cellphone and you can easily login to your Aadhar Self Update Portal and further update it. You will be required to upload certain documents for updating your Aadhar Card information.
In case, your mobile number registered in the Aadhar Card is incorrect. Then, you won't be able to login in Aadhar Self Service Update Portal and ultimately, you can't update your Aadhar Card Online. Now, other option for you is to update your Aadhar Card through Speed post. You will have to download a Aadhar Update Form, fill it and send it to your regional office with relevant documents.
After the successful submission of the Form in the regional office, you will get a confirmation message at your registered mobile number. And within a month, a new Aadhar Card will be delivered at your Address.
