An Aadhaar card does not need to be renewed in the traditional sense, as it is a lifetime document. However, the information on the card, such as your address or mobile number, may change over time and will need to be updated.

It’s important to keep your Aadhaar card information up to date as it is used as proof of identity and address for various services, such as opening a bank account, applying for a PAN Card, and obtaining a SIM card for a mobile phone.

You can update your Aadhaar card information by visiting an Aadhaar Enrollment Center, where you will need to fill out an update form and provide proof of the new information. You can also update your information online by visiting the UIDAI website, where you can download the form, fill it out, and then upload the form along with the required documents.

You can also update some information like mobile number, email address and Biometric data like fingerprints, iris scan, and photographs online by visiting the UIDAI website and authenticating it by OTP sent to your registered mobile number.

It’s worth mentioning that if your biometric data (fingerprints, iris scan) or photograph on your Aadhaar card becomes outdated or worn out, you can visit an Aadhaar Enrollment Center to update your biometric data and photograph.
