If you are searching for the Aadhaar age limit in India 2026, the answer is that there is no minimum age for Aadhaar enrolment. UIDAI says even a newborn baby can be enrolled. What changes with age is the way the child’s Aadhaar is enrolled and when biometric information must be added or updated.
For a child below 5 years, UIDAI does not capture the child’s fingerprints and iris at enrolment. The child’s photograph, demographic details and parent/guardian information are recorded. When the child reaches 5, the child must provide biometrics. A second mandatory biometric update is required at age 15.

Quick answer: what is the Aadhaar age limit?
There is no minimum age for Aadhaar enrolment. UIDAI’s current FAQ says even a newborn can be enrolled. The important age milestones are 5 years and 15 years, because children’s biometric information is updated at those stages.
| Age | What generally happens | Biometric position |
|---|---|---|
| Birth to under 5 | Child can be enrolled with parent/guardian involvement | Child’s fingerprints and iris are not captured at initial enrolment |
| Age 5 | Mandatory biometric update | Photo, fingerprints and iris are captured/updated |
| Age 15 | Second mandatory biometric update | Biometrics are updated again |
| 18 and above | Adult Aadhaar services apply | Normal adult biometric rules apply |
Can a newborn baby get Aadhaar?
Yes. UIDAI states that there is no age limit for Aadhaar enrolment and that even a newborn baby can be enrolled. For a child below 5, a parent or legal guardian accompanies the child and gives consent/authentication on the child’s behalf.
For a resident Indian child below 5, UIDAI’s current guidance says the child’s name, date of birth, gender, address and photograph are captured, along with the relevant parent/guardian information. A birth certificate is mandatory for a child born on or after 1 October 2023 under the current UIDAI guidance.
Aadhaar rules for children below 5
A child can have an Aadhaar number before the fifth birthday, but the initial enrolment is different from an adult enrolment. UIDAI’s 2026 handbook explains that children below 5 do not have fingerprints and iris captured during enrolment. Instead, the child’s photograph and demographic details are recorded and the Aadhaar is linked to a parent or guardian as prescribed.
- Parent/guardian involvement: a parent or legal guardian accompanies the child and provides the required authentication and consent.
- Child’s photograph: the child’s facial image is captured.
- Demographic details: name, date of birth, gender and address are recorded.
- Birth documentation: UIDAI’s current guidance requires a birth certificate for children born on or after 1 October 2023.
- No fingerprints or iris at initial enrolment: these biometrics are captured later when the child reaches the applicable age.
What happens when a child turns 5?
Turning 5 is a major Aadhaar biometric milestone. UIDAI says a child who was initially enrolled below 5 should provide biometric information when the child attains age 5. The update includes the child’s photograph, fingerprints and iris scans. The original Aadhaar number continues to be used rather than creating a new Aadhaar number.
UIDAI describes this as a Mandatory Biometric Update (MBU). Parents should therefore not assume that the Aadhaar issued during infancy is a finished biometric record that never needs updating.
What happens at age 15?
A second mandatory biometric update occurs when the Aadhaar number holder reaches 15. UIDAI’s current update guidance says that a person who was enrolled between ages 5 and 15 should furnish all biometrics when the person attains 15.
This second update is important because fingerprints, iris patterns and facial appearance change as children grow. The practical rule for parents is therefore easy to remember: check Aadhaar biometrics around age 5 and again around age 15.
What is Mandatory Biometric Update?
Mandatory Biometric Update means that specified biometric information must be captured or refreshed at the child-age milestones prescribed by UIDAI. The current Aadhaar regulations state that biometric information collected for enrolment includes the facial image, all ten fingerprints and both iris scans for individuals other than children below 5.
For children, the key point is that the biometric stage is delayed until the child reaches the prescribed age. The Aadhaar number itself does not change merely because the child completes the mandatory biometric update.
Is the child biometric update free in 2026?
As of 18 September 2026, UIDAI’s current website states that Mandatory Biometric Update (MBU) is free of cost for children aged 5–17 until 30 September 2026. UIDAI’s service information also lists free biometric-update windows for children in the relevant age bands. Because fees and temporary waivers can change, parents should check the live UIDAI fee information before visiting an enrolment centre.
Do not confuse the temporary/current fee position with the age rule itself. The requirement to update biometrics at the child milestones is separate from whether UIDAI is charging a fee on a particular date.
Documents needed for child Aadhaar
The exact document set depends on the child’s age, enrolment route and circumstances. UIDAI’s current guidance gives these practical examples:
- Below 5 years: the parent/guardian’s Aadhaar information and the child’s required birth/DOB documentation are important for enrolment.
- Born on or after 1 October 2023: UIDAI says the birth certificate is mandatory for the child.
- Age 5 to 18: a child’s school ID issued by a recognised educational institution or another UIDAI-accepted document may be used for own-document enrolment; Head-of-Family enrolment is also available where the prescribed relationship document is used.
- Parent/guardian consent: a parent or guardian gives consent for a minor’s Aadhaar enrolment as prescribed.
Because UIDAI’s acceptable-document list is updated periodically, use the current document list on UIDAI’s website rather than relying on an old photocopy checklist.
How to update a child’s Aadhaar biometrics
- Check the child’s date of birth. Work out whether the child has reached the 5-year or 15-year biometric milestone.
- Check the existing Aadhaar details. Make sure the name and date of birth are correct before the visit.
- Collect the required documents. Use UIDAI’s current acceptable-document list for the child’s circumstances.
- Visit an Aadhaar Enrolment/Update Centre. The biometric update is performed through the prescribed centre process.
- Have the child present. The child’s biometrics must be captured in person.
- Review the acknowledgement. Check the request details before leaving the centre.
- Track the update. Keep the acknowledgement/reference details until the update is completed.
UIDAI’s current enrolment guidance directs residents to nearby Aadhaar Enrolment Centres or Aadhaar Camps for enrolment and related services.
Aadhaar age and date of birth rules
Age calculations for Aadhaar are based on the child’s recorded date of birth. This makes the exact DOB important when deciding whether a child has reached the 5-year or 15-year milestone.
For example, a child born on 20 September 2021 reaches age 5 on 20 September 2026. A child born on 20 September 2011 reaches age 15 on 20 September 2026. You can use the site’s Age Calculator to calculate the child’s exact age on a particular date.
Aadhaar age examples by date of birth
| Date of birth | Milestone | When it occurs |
|---|---|---|
| 20 September 2025 | Age 5 | 20 September 2030 |
| 20 September 2021 | Age 5 | 20 September 2026 |
| 20 September 2011 | Age 15 | 20 September 2026 |
| 20 September 2008 | Age 18 | 20 September 2026 |
These are calendar-age examples only. The actual Aadhaar service and document requirements should always be checked against the current UIDAI instructions.
What changes after age 18?
Turning 18 is not an Aadhaar enrolment deadline and does not mean that a person needs a new Aadhaar number. Aadhaar is already issued to the individual if they were enrolled as a child. The child’s Aadhaar number continues to be associated with that person.
The more important child-specific Aadhaar milestones are 5 and 15. For a broader explanation of what legally changes at 18 in India, see the site’s age of majority in India guide.
Common mistakes parents should avoid
- Waiting until 18 to enrol: Aadhaar has no minimum enrolment age, and a newborn can be enrolled.
- Assuming an infant Aadhaar has adult biometrics: children below 5 do not have fingerprints and iris captured at initial enrolment.
- Forgetting the age-5 update: the first mandatory biometric milestone is at 5.
- Forgetting the age-15 update: a second mandatory biometric update is required at 15.
- Using an old fee chart: fee waivers can change, so check UIDAI’s live fee information before the visit.
- Using outdated document lists: use UIDAI’s current acceptable-document list for the child’s age and enrolment route.
- Entering the wrong DOB: the recorded date of birth determines when age-based milestones are reached.
