“Aadhaar Biometric Updates for Children Aged 5–15 Yrs are mandatory at age 5 and 15 to capture fresh fingerprints, iris scans, and photos. Learn why these updates matter, free update windows, required documents, step-by-step process, school camps, charges, and how to avoid Aadhaar deactivation for your child.”
Keeping a child’s Aadhaar up-to-date isn’t just good housekeeping—it’s required. UIDAI (the Unique Identification Authority of India) mandates Mandatory Biometric Updates (MBU) at two milestones in a child’s life: age 5 and age 15. These updates refresh the child’s fingerprints, iris scans and photo so their Aadhaar continues to work smoothly for school admissions, scholarships, exam registrations, and bank or government scheme verifications as they grow.
Below is a clear, parent-friendly explainer that covers the what, why, when, where and how, along with a detailed step-by-step process and practical FAQs.
What exactly is the “Mandatory Biometric Update” (MBU)?
- MBU at 5: When a child turns five, UIDAI requires capturing their fingerprints and irises for the first time (children enrolled below five only have a photo plus demographic info). This first MBU is free if done between ages 5 and 7.
- MBU at 15: When the child turns fifteen, UIDAI requires re-capturing biometrics because adolescents’ features change rapidly. This second MBU is free if done between ages 15 and 17.
- Missed the free window? You can still update any time later at a centre by paying the standard service fee (currently ₹100 for any biometric update with or without a demographic change; ₹50 for demographic-only updates). Check the official charges page for the latest rates.
- Your child’s Aadhaar number stays the same. UIDAI clarifies the MBU is treated like a (re)enrolment for de-duplication, but the same Aadhaar number is retained.
Why are these updates important?
- Growing children = changing biometrics. Fresh biometrics keep identity checks reliable in schools, exam centres, banks and for DBT benefits.
- Smooth KYC and fewer failed authentications. Updated biometrics reduce the chance of rejection when a child needs to authenticate for services or benefits.
- Timely updates are now being actively driven through schools. UIDAI has asked schools nationwide to help families complete pending MBUs for children aged 5–15. Expect local school notices or on-campus camps as states roll out the push.
- Risk of deactivation if you ignore it: Media advisories consistently note that a minor’s Aadhaar may be deactivated if the mandatory update isn’t done in time. Don’t let it linger. (This is a widely reported advisory in mainstream outlets.)
Who must update—and when?
- All children who were enrolled below age 5 (sometimes called Baal Aadhaar) must complete MBU at age 5, then again at age 15.
- Free windows:
First MBU: From 5th birthday up to, but not including, the 7th birthday (i.e., ages 5–7).
Second MBU: From 15th birthday up to, but not including, the 17th birthday (i.e., ages 15–17).
Both are free in these windows at authorised centres. Outside these windows, normal update charges apply.
Example timeline: If your child was born on 10 February 2018:
- Turns 5 on 10 Feb 2023 → Free MBU until 09 Feb 2025.
- Turns 15 on 10 Feb 2033 → Free MBU until 09 Feb 2035.
After those dates, you can still update anytime by paying the applicable fee.
Where to get the update done
You have two broad options:
Any authorised Aadhaar Enrolment/Update Centre or Aadhaar Seva Kendra (ASK):
You can visit any centre (it need not be the one where you first enrolled). Biometrics must be updated in person.
To find a nearby centre, use the official Bhuvan Aadhaar map. You can search by pin code, area, state/district, or “Centres Nearby” and even filter by “Biometric Update”.
School-facilitated camps (where announced):
UIDAI has asked schools to coordinate MBUs for students aged 5–15. Watch for circulars from your child’s school about on-campus sessions or assistance.
What to carry (documents checklist)
- Child’s Aadhaar number (or the original Aadhaar letter/e-Aadhaar on phone).
- Parent/guardian’s Aadhaar (one parent/guardian must authenticate and give consent for a minor).
- Birth certificate: Mandatory if the child was born on or after 01-10-2023. For older children, carry an accepted Proof of Date of Birth (PDB) if you also plan to correct/confirm the DOB.
- If you’re also updating address or other demographics, carry valid POI/POA/PoR/PDB as per UIDAI’s latest “List of Acceptable Supporting Documents”.
Tip: You don’t need to bring a photograph—the operator captures a fresh photo at the centre.
The detailed, step-by-step process (with pro tips)
Step 1: Confirm that your child is due for MBU
If your child has crossed 5 (or 15), they’re due. UIDAI also sends SMS reminders to registered numbers. Schools may share schedules for on-campus updates as well.
Step 2: Choose where to do it
- Regular centre/ASK: Use Bhuvan Aadhaar to locate a centre that offers Biometric Update service. Shortlist two centres (one as a backup) in case slots are busy.
- School camp (if available): Follow the school’s instructions, submit any consent form they provide, and note your child’s slot/time.
Step 3: (Optional but helpful) Book an appointment
Many UIDAI-run ASKs support online appointments; you can also visit on a walk-in basis depending on the centre. Appointment booking helps avoid queues.
Step 4: Prepare documents and the child
- Pack: child’s Aadhaar, parent’s Aadhaar, and (if needed) birth certificate/supporting documents for any demographic changes.
- Make sure the child is well-rested and hydrated—it helps with still photos and iris capture. (Not a UIDAI rule, just practical advice.)
Step 5: Visit the centre
- Take a token and select “Biometric Update (Child/Minor)” if the centre uses a queuing system.
- Operator verification: Your identity is verified; you’ll sign/consent for the minor’s update.
Step 6: Capture biometrics & photo
- The operator captures fingerprints, irises, and a fresh photograph of the child. If any capture fails the quality check, they’ll retry (different finger, re-attempt iris, adjust lighting).
- No photos from home are used; images are taken on the spot under UIDAI standards.
Step 7: Review details
The operator will show your child’s demographic data (name, DOB, gender, address) on screen. Use the opportunity to correct typos or update address/mobile/email (demographic updates may carry a nominal fee).
Step 8: Acknowledgement slip
You’ll receive an acknowledgement slip with an Update Request Number (URN) or EID. Keep this safe—it’s needed to track status. UIDAI
Step 9: Track status online
Use “Check Aadhaar Update Status” under My Aadhaar → Update Your Aadhaar to track the URN/EID.
Step 10: Download the updated Aadhaar
- Once processed, download e-Aadhaar from the official portal or the mAadhaar app.
- e-Aadhaar is legally as valid as the physical card for all purposes; you can use it immediately while you wait for a printed PVC (if you order one).
How long does it take?
- The in-centre process itself is quick (usually minutes, depending on queues).
- Back-end processing timelines vary by load; track using your URN/EID and download e-Aadhaar as soon as it’s ready.
Fees you might encounter (and how to avoid them)
- Aadhaar enrolment: Free.
- MBU at ages 5 and 15 (within the free windows 5–7 and 15–17): Free.
- Biometric update outside the free window: ₹100 (with or without demographic update).
- Demographic-only update (e.g., address, DOB correction): ₹50.
- Download & coloured print at centre: ₹30 (optional—you can download at home for free).
Always rely on UIDAI’s official charges page/PDF for the current fees.
Special notes for enrolment of young children and NRIs
- Children enrolled below 5: At first enrolment (pre-5), only the photo and demographics are captured; the parent/guardian authenticates and consents. At 5, the child’s own biometrics are captured during MBU.
- Births on/after 01-10-2023: Birth certificate is mandatory for the child’s enrolment. Keep it ready, especially if you will correct or confirm DOB during an MBU.
- NRI children: For NRI enrolment, a valid Indian passport for the child is mandatory as PoI; other rules follow UIDAI norms. (MBU principles at 5 and 15 still apply.)
What if you miss the age-based window?
- You can still update any time later—just pay the standard biometric update fee. Your Aadhaar number remains the same.
- Don’t delay: widespread advisories indicate possible deactivation for minors whose MBUs aren’t completed in time. Schools and state drives are actively nudging families to finish pending updates.
Frequently asked questions (FAQs)
1) Do we need the child physically present?
A: Yes. Biometrics (fingerprints/iris) and a live photograph must be captured in person at an authorised centre.
2) Will the Aadhaar number change after MBU?
A: No. UIDAI explicitly says the same Aadhaar number is retained after MBU (the update simply refreshes biometrics and re-checks for duplicates).
3) Can we do the biometric update online?
A: No. Biometric updates require a centre visit. Online is available only for certain document-based demographic updates (e.g., address), not for capturing fingerprints/iris.
4) Which centre should we use?
A: Any authorised centre or ASK works—you’re not restricted to the original enrolment centre. Use Bhuvan Aadhaar to find one near you.
5) What if fingerprints don’t capture well?
A: Operators will retry captures (different fingers/attempts/iris). If quality remains poor (e.g., due to cuts/temporary issues), the operator will advise a re-attempt later. (This is operational practice; there isn’t a separate online route.)
6) Is e-Aadhaar accepted everywhere?
A: Yes. e-Aadhaar (downloaded PDF) is legally equivalent to the physical Aadhaar letter/PVC. You can present it digitally or print it yourself.
7) Can we update mobile/email too?
A: Yes, you can update mobile/email/address along with biometrics at the centre (demographic updates may have a nominal fee). Some demographic changes can also be done online.
8) Will schools handle this for everyone?
A: UIDAI has asked schools to support MBUs; whether your school runs an on-campus drive depends on local arrangements. Keep an eye on school notices.
A parent’s action plan (checklist)
- Mark the dates. Put reminders for your child’s 5th and 15th birthdays, plus the end of the free window (7th and 17th birthdays).
- Watch for school notices about on-campus MBU camps. If none are planned, plan a centre visit yourself.
- Use Bhuvan Aadhaar to locate a centre that offers Biometric Update; book an appointment if available.
- Carry the right documents: child’s Aadhaar, parent’s Aadhaar, and birth certificate (mandatory for births on/after 01-10-2023) or other supporting documents if you’re changing demographics.
- Complete the capture (fingerprints, iris, photo), review demographics, and collect the acknowledgement with URN/EID.
- Track status online and download e-Aadhaar as soon as it’s ready. e-Aadhaar is fully valid.
Common edge cases and how to handle them
- Child’s DOB or name needs correction too: Bring the relevant proofs and do it in the same visit. Demographic corrections may incur the ₹50 fee, separate from the free MBU.
- Parent’s mobile number has changed: You can update the registered mobile at the centre (needed for OTP-based logins and downloads later).
- NRI child is visiting briefly: Prioritise the visit during the stay; bring the valid Indian passport (PoI) and other acceptable documents as per the latest UIDAI list.
- Lost the paper Aadhaar: No problem—e-Aadhaar download is accepted everywhere. Order a PVC card later if you like; it’s optional.
Final word
Aadhaar’s child MBU at 5 and 15 years is straightforward, free in its designated windows, and crucial for keeping your child’s identity records accurate as they grow. Do it at any authorised centre (or through a school camp if offered), keep the acknowledgement safely, and download e-Aadhaar once processed. Set date reminders, use Bhuvan Aadhaar to find a nearby facility, and you’ll be done in one efficient visit.
