Learn how to update your Aadhaar biometric details to avoid authentication failures and ensure your identity is verified correctly across government and financial services.
.webp)
Outdated biometric data is often a cause of Aadhaar authentication failure during banking, subsidies, or mobile verification. This usually can be easily remedied with an Aadhaar biometric update. It helps correct the fingerprint and iris mismatches that build up over time due to age, wear on fingerprints, or earlier capture errors. Biometric update is necessary to keep your digital identity functional within the UIDAI system and reduce the risk of service disruption during identity verification. In this guide, we answer all questions around how to update biometric in Aadhaar card.
Aadhaar biometric data refers to the physical identifiers stored in the UIDAI database and used for identity verification. This data links an individual to their Aadhaar number and enables biometric authentication across government and financial systems.
What is biometric update in Aadhar card?
Fingerprint data captured using a certified fingerprint scanner
Iris scans captured through approved biometric devices
Photograph of the Aadhaar holder
These identifiers form the core of the Aadhaar biometric system and are used to confirm biometric identity. It is specially required for services such as banking, subsidies, SIM verification, and other forms of individual identification.
An Aadhaar card biometric update is needed when the biometric data stored with UIDAI no longer matches an individual’s current physical identifiers, leading to authentication failures.
An Aadhaar biometric update is required when existing biometric data no longer supports reliable identity verification within the UIDAI system. The following individuals should update their biometrics:
Children enrolled under Baal Aadhaar who have reached age 5 or 15, as mandated by UIDAI
Adults facing repeated biometric authentication failure due to outdated Aadhaar fingerprint update or iris mismatch
Individuals with biometric changes caused by ageing, injury, illness, or extensive manual work
Aadhaar holders with poor-quality biometric capture during earlier enrolment or updates
Aadhaar biometric requirements for children are age-specific and designed to account for natural physical development. UIDAI mandates biometric updates at defined stages to maintain accurate identity records.
The biometric update process for children follows the same Aadhaar update process used for adults and is completed at an authorised Aadhaar Enrolment Center.
Aadhaar biometric updates are carried out through defined modes set by UIDAI. These modes differ based on whether biometric capture is required. So, if you are looking for answers to how to update Aadhaar biometric, here is your answer:
An Aadhaar biometric update can only be completed in person at an authorised Aadhaar Enrolment Center. Biometric data such as fingerprint data, iris scans, and photographs must be captured live using UIDAI-approved biometric capture methods and devices. This ensures accuracy, prevents misuse, and maintains the integrity of the Aadhaar Biometric System.
While parts of the Aadhaar update process, such as address updates, can be initiated online, biometric submission cannot be done online. UIDAI does not support aadhaar biometric update online due to the need for physical biometric authentication using certified scanners.
An Aadhaar biometric update can only be completed offline. UIDAI does not allow biometric submission online due to mandatory physical verification.
Visit a Aadhaar Enrolment Center
Fill out the Aadhaar Enrolment or Update Form
Submit the form along with your Aadhaar details to the centre executive
Provide biometric data, including fingerprint data and/or iris scans, using UIDAI-approved devices
After verification, the executive updates and locks the data in the UIDAI database
Pay the UIDAI service fee of ₹50 for the biometric update
UIDAI does not support aadhaar biometric update online. Only non-biometric details such as address can be updated through online services.
To complete an Aadhaar biometric update, UIDAI requires minimal documentation since biometric identity is verified through live biometric capture at the enrolment centre.
You need the following Aadhaar biometric update documents:
Aadhaar card or Aadhaar number for identification
Aadhaar card biometric update form (Aadhaar Enrolment or Update Form), duly filled
Guardian’s Aadhaar and consent in case of biometric update for children
No additional identity or address proof is required for biometric updates, as verification is completed through biometric authentication at the Aadhaar Enrolment Center.
UIDAI has fixed charges for Aadhaar biometric updates. The fee depends on the age of the Aadhaar holder and whether the update is mandatory or optional.
These charges are standard UIDAI charges and apply at all authorised Aadhaar Enrolment Centers.
An Aadhaar biometric update is usually processed within 5 to 10 working days after biometric submission at the Aadhaar Enrolment Center. Once the biometric data is captured and uploaded, UIDAI verifies and updates the information in the UIDAI database. In some cases, processing may take longer due to verification checks or system load. If you are looking for how to check if biometric is updated in Aadhar card, you will need Update Request Number (URN) to track the status on the UIDAI portal or ask at the enrolment center.
Aadhaar biometric data enables accurate identity verification across services that rely on the UIDAI system. Keeping this data updated ensures uninterrupted access and reduces verification errors.
Aadhaar biometric authentication can fail when the biometric data stored in the UIDAI database does not match the live biometric capture. The most common causes are listed below:
Worn or unclear fingerprints due to ageing, manual labour, or skin conditions
Outdated biometric data that has not been updated after physical changes
Poor-quality biometric capture during earlier enrolment or updates
Injuries or medical conditions affecting fingerprints or iris patterns
Data mismatch within the UIDAI system caused by partial or incorrect biometric submission
In such cases, UIDAI recommends an Aadhaar biometric update to restore successful biometric authentication.
Keeping your Aadhaar biometric data accurate is essential for seamless identity verification across banking, government services, and digital platforms. Regular updates, especially for children and individuals experiencing biometric changes, prevent authentication failures and ensure your digital identity remains secure within the UIDAI system. Visiting an authorised Aadhaar Enrolment Center for updates is the only reliable way to maintain accurate biometric records.
You need your Aadhaar card or Aadhaar number and a completed Aadhaar Enrolment/Update Form. For children, guardian consent is also required. No additional identity or address proof is needed, as verification is done via live biometric capture.
Visit an authorised Aadhaar Enrolment Center with your Aadhaar number, fill the enrolment/update form, and provide your fingerprints and/or iris scans. The centre updates your biometric data in the UIDAI database after verification.
No, UIDAI does not allow online biometric updates. Biometric data must be updated offline at an authorised Aadhaar Enrolment Center using certified scanners for accurate authentication.
No, your Aadhaar number remains the same. Only the biometric records in the UIDAI database are updated. The physical Aadhaar card does not change.
There is no fixed limit, but UIDAI recommends updates only when necessary, such as after ageing, injury, or failed authentication. Each update incurs the standard ₹50 fee for adults.
Updating biometrics is mandatory for children at ages 5 and 15. For adults, it is only required if authentication fails due to outdated or mismatched data.
Biometric updates are generally processed within 5 to 10 working days after submission at the Aadhaar Enrolment Center. Delays can occur due to verification checks or system load.
Update only when biometric authentication fails or for children at ages 5 and 15. Adults usually do not need regular updates unless fingerprints or iris patterns change.
Visit the Aadhaar Enrolment Center or check the status of your update request using the Update Request Number (URN) on the UIDAI portal to confirm if biometric data has been updated.
Yes, if your fingerprints or iris scans have changed or if a child reaches age 5 or 15. Accurate biometrics prevent authentication failures in banking, subsidies, and government services.
Yes, biometric updates can be done at any authorised Aadhaar Enrolment Center, regardless of your current registered address. Ensure the centre has UIDAI-certified biometric devices.
Failure to update may lead to authentication failure, preventing access to banking, subsidies, SIM verification, or other Aadhaar-linked services.
No, the Aadhaar number remains unchanged. Only the biometric records in the UIDAI database are updated; a new physical card is not issued.
