The Unique Identification Authority of India (UIDAI) has completed more than 2 crore Mandatory Biometric Updates (MBU) for school-going children as part of a nationwide mission-mode initiative aimed at ensuring that Aadhaar records are updated as children grow.
The special drive, launched in September 2025, has expanded the reach of Aadhaar biometric update services by taking the process directly to schools. So far, more than 1.56 lakh schools across the country have been covered under the initiative, allowing children to complete their mandatory biometric updates through dedicated camps organised within school premises.
The programme is being implemented through coordination between UIDAI and education departments across states and Union Territories. A key component of the initiative is its technological integration with the Unified District Information System for Education Plus (UDISE+), enabling schools to track the Mandatory Biometric Update status of children.
The initiative is intended to reduce the inconvenience faced by children and parents in completing Aadhaar-related requirements and to encourage timely biometric updates.

UIDAI’s Nationwide Mission-Mode Drive
The UIDAI has been undertaking the special MBU drive since September 2025 with the objective of increasing awareness and completion of mandatory biometric updates among children.
Under the programme, schools serve as important points of access for Aadhaar biometric services. Dedicated camps allow eligible students to complete their updates without having to independently arrange visits to Aadhaar enrolment or update centres.
According to the information released by the authority, the drive has already covered more than 1.56 lakh schools nationwide and resulted in more than 2 crore mandatory biometric updates.
The scale of the programme highlights the importance of coordination between India’s Aadhaar ecosystem and its education infrastructure.
Rather than treating Aadhaar updates as an isolated administrative requirement, the initiative integrates the process into the school environment, where eligible children can be identified and guided through the update procedure.

What Is a Mandatory Biometric Update?
A Mandatory Biometric Update, commonly known as MBU, refers to the process through which a child’s Aadhaar biometric information is updated at specified stages of childhood.
When Aadhaar is initially enrolled for a child below five years of age, the child’s demographic information and photograph are captured. However, fingerprints and iris biometrics are not recorded at that stage because these biometric characteristics are still developing.
As children grow, their biometric characteristics become sufficiently developed for Aadhaar authentication purposes. The mandatory update process allows the Aadhaar record to be updated with the child’s biometric information.
MBU is required at two key stages: when the child reaches five years of age and again at 15 years.
These updates are designed to ensure that the biometric information associated with a child’s Aadhaar remains appropriate as the child grows.
Why Biometric Updates Are Important for Children
Children undergo significant physical development between early childhood and adolescence. Because fingerprints and other biometric characteristics can change as a child grows, the Aadhaar system requires updates at specified ages.
Completing the MBU on time helps ensure that the Aadhaar record contains updated biometric information.
This can be particularly important as children begin accessing services and systems where Aadhaar authentication may be required.
For school-going children, Aadhaar-related requirements can become relevant in connection with educational records, government benefits, registrations and other services.
UIDAI has therefore encouraged parents and guardians to ensure that eligible children complete their mandatory biometric updates within the prescribed timelines.

MBU Can Help With Aadhaar Authentication
One of the main reasons for completing biometric updates on time is to support smoother Aadhaar authentication.
Aadhaar is increasingly used as an identity verification mechanism for accessing various government services and benefits. When a child’s biometric information has not been updated as required, authentication-related difficulties may arise in certain circumstances.
Timely MBU helps ensure that the child’s Aadhaar record reflects their updated biometric information as they progress through school and eventually into higher education.
For families, completing the update when it becomes due can therefore help avoid administrative complications later.
MBU Requirements at Ages 5 and 15
The Aadhaar biometric update framework requires children to undergo the process at two important stages.
The first Mandatory Biometric Update is required when a child reaches five years of age.
The second MBU is required when the child reaches 15 years of age.
These milestones reflect the physical development of children during different stages of childhood and adolescence.
Parents and guardians should therefore keep track of their child’s age and Aadhaar update status rather than waiting until an authentication requirement or application deadline creates an urgent need for an update.

UIDAI Makes MBU Free for Children Aged 5 to 17
To encourage families to complete mandatory biometric updates, UIDAI has made MBU free for children aged 5 to 17 years until September 30, 2026.
The authority had previously announced a waiver of charges for children in the 7 to 15 years age group from October 1, 2025, for a period of one year.
According to the information provided, MBU for children aged 5-7 years and 15-17 years also continues to be free.
The fee waiver is intended to remove a potential financial barrier for families and encourage timely compliance with Aadhaar biometric update requirements.
With the current free-update period scheduled to continue until September 30, 2026, parents of eligible children are being encouraged to make use of the facility.
Schools Become Key Access Points for Aadhaar Updates
A major feature of the UIDAI initiative is the decision to take biometric update services directly to schools.
For many parents, visiting an Aadhaar centre can require additional travel, time and coordination around school and work schedules.
By organising dedicated MBU camps at schools, the initiative attempts to make the process more accessible.
Children can complete the update process in an environment they already regularly visit, while schools can help identify eligible students and facilitate communication with parents.
This school-based approach can also be particularly useful in expanding access across different parts of the country.

UDISE+ Integration Helps Schools Track MBU Status
The programme also incorporates technological coordination between UIDAI and the Unified District Information System for Education Plus (UDISE+).
UDISE+ is an important education data platform used for school-related information and monitoring across India.
Under the MBU initiative, integration with the education system enables schools to track the biometric update status of children.
This can help schools identify students who may still need to complete their mandatory updates and support targeted outreach to families.
The use of digital tracking can also improve coordination between education authorities and UIDAI, allowing the campaign to operate on a larger scale.
Coordination Between UIDAI and Education Departments
The nationwide programme requires coordination between several levels of government.
UIDAI has worked with education departments of states and Union Territories to expand awareness and facilitate the organisation of biometric update camps in schools.
This coordination is important because education departments have direct access to school networks and can help communicate information to students, parents and school administrators.
The approach also allows the MBU programme to reach large numbers of children without requiring every family to independently navigate the Aadhaar update process.
The more coordinated the outreach, the easier it becomes to identify eligible students and organise update camps in locations that are convenient for them.
Why Parents Should Not Delay the Update
UIDAI has advised parents and guardians to ensure that their children’s mandatory biometric updates are completed on time.
Delaying the update may create complications if the child later needs Aadhaar authentication for an important service or registration.
The authority has specifically highlighted potential relevance to government scheme benefits as well as registrations connected with competitive and university examinations.
For students preparing for major examinations, completing Aadhaar-related requirements in advance can help reduce administrative uncertainty during application periods.
Aadhaar and Competitive Examinations
Aadhaar authentication can form part of identity verification processes associated with various examinations and educational services.
UIDAI has highlighted examinations such as NEET, JEE and CUET in advising parents about the importance of maintaining updated Aadhaar records.
NEET is a major entrance examination for medical education, while JEE is used for admission to engineering and other technical programmes. CUET provides an admission route to numerous higher education institutions.
For students approaching these examination stages, ensuring that Aadhaar information is updated well in advance can help avoid potential complications related to identity verification.
This is particularly relevant because examination applications often operate within fixed deadlines, leaving limited time to resolve documentation or authentication issues.
Supporting Access to Government Benefits
The importance of MBU also extends beyond education.
Aadhaar authentication is used in connection with various government services and welfare schemes. Maintaining an updated Aadhaar record can help beneficiaries complete identity verification requirements where Aadhaar authentication is applicable.
For children and their families, this can include services or benefits where identity verification is required.
UIDAI’s emphasis on timely biometric updates is therefore intended to ensure that Aadhaar records remain usable as children transition through different stages of life.
The Scale of the Campaign
The completion of more than 2 crore MBUs demonstrates the scale of the ongoing campaign.
Covering more than 1.56 lakh schools also indicates the extensive reach of the school-based approach.
The numbers are significant because India’s school network provides a broad platform through which government services and awareness campaigns can reach children and families.
By combining school-level outreach with digital tracking through UDISE+, the initiative attempts to create a more systematic mechanism for identifying and completing pending updates.
Making Aadhaar Services More Accessible
The school-based MBU initiative reflects a broader effort to make essential identity-related services more accessible to citizens.
Instead of requiring parents to arrange separate visits to Aadhaar centres, the programme brings the service closer to children.
This approach can be especially useful for families who face logistical challenges, including travel time, work commitments or limited access to nearby update facilities.
Dedicated camps can also create a more structured environment for completing updates, particularly when schools coordinate the process with education authorities and UIDAI.
What Parents Should Do Now
Parents and guardians should first determine whether their child is due for a Mandatory Biometric Update based on their age and Aadhaar history.
They should pay attention to communications from their child’s school regarding MBU camps and update schedules.
Parents should also ensure that the child’s Aadhaar details are correctly recorded and follow the instructions issued by UIDAI and the concerned school or education department.
Since the current fee waiver for children aged 5 to 17 is available until September 30, 2026, eligible families have an opportunity to complete the update without paying the applicable MBU charge during the waiver period.
UIDAI’s Broader Objective
The ongoing campaign reflects UIDAI’s effort to ensure that Aadhaar records remain accurate and functional as children grow.
The biometric update requirement recognises that children’s biometric characteristics develop over time and that information captured during early childhood may not remain sufficient for later authentication.
By encouraging timely updates and integrating the process with schools, UIDAI aims to improve compliance while reducing the administrative burden on families.
The use of education databases and school networks also allows the initiative to operate at a scale that would be difficult to achieve through individual outreach alone.
The UIDAI has completed more than 2 crore Mandatory Biometric Updates for school children under its nationwide mission-mode drive launched in September 2025. More than 1.56 lakh schools have so far been covered, with dedicated camps helping children complete their Aadhaar biometric updates within school premises.
The programme combines UIDAI’s Aadhaar infrastructure with the education system through integration with UDISE+, allowing schools to track MBU status and coordinate outreach with parents.
For children, the biometric update is important because fingerprints and iris information are not captured when Aadhaar is initially enrolled before the age of five. MBU is subsequently required at ages five and 15 as biometric characteristics develop.
With MBU currently free for children aged 5 to 17 until September 30, 2026, UIDAI is encouraging parents and guardians to complete the process within the applicable timeline.
The authority has also emphasised that timely updates can help children avoid potential authentication-related difficulties when accessing government services, benefits and registrations for major examinations such as NEET, JEE and CUET.
As the nationwide campaign continues, the school-based approach is expected to remain an important mechanism for reaching children and ensuring that their Aadhaar records are updated at the appropriate stages of their development.
