Blue Aadhaar vs White Aadhaar: Blue Aadhaar, also known as Baal Aadhaar, is issued to children below five years of age. Unlike regular Aadhaar enrolment, fingerprints and iris details are not captured for children in this age group. At five, a Mandatory Biometric Update is required, while the child’s original Aadhaar number remains unchanged. In 2026, child Aadhaar enrolment through India Post Payments Bank’s doorstep service has also received renewed attention.

What Is Blue Aadhaar or Baal Aadhaar?
The Unique Identification Authority of India (UIDAI) issues Aadhaar as an identity document for residents. Along with the regular Aadhaar, UIDAI has a specific enrolment process for children below five years.
The blue Aadhaar is commonly known as Baal Aadhaar. The Press Information Bureau has explained that children in the 0–5 age group are issued Baal Aadhaar. It is issued in blue to distinguish it from normal Aadhaar and carries a remark that it is valid until the child attains five years of age.

Baal Aadhaar is intended to provide children with a digital photo identity from birth and can facilitate access to welfare benefits and services where Aadhaar is required.
Why Children Below Five Do Not Give Fingerprints or Iris Scans
Biometric information is an important part of Aadhaar because fingerprints and iris data are used to establish uniqueness. However, for children below five, UIDAI does not capture fingerprints and iris images during initial enrolment.
Instead, the child’s facial image is captured. One parent or the legal guardian authenticates the child’s enrollment. UIDAI’s enrolment procedure also requires the relevant demographic information and supporting documents. For a resident Indian child, the mandatory demographic details include the child’s name, date of birth, gender and address. Details of the mother, father or legal guardian are also captured where applicable.
For children born on or after October 1, 2023, UIDAI states that the birth certificate is mandatory for enrolment.
The earlier information about using a birth certificate or proof of relationship, and the possibility of providing an Aadhaar-linked parent or guardian for authentication, therefore forms part of the child enrolment process.
What Happens When a Child Turns Five?
The most important change comes when the child reaches five years of age.
UIDAI requires the child’s biometric information to be recorded at this stage. The update includes:
- Photograph
- Fingerprints
- Both iris scans
A de-duplication process is carried out, and the request is treated similarly to a new enrolment. However, the original Aadhaar number is retained.
This distinction is important because saying that the Aadhaar number becomes invalid or changes permanently at five would be inaccurate. The official process is a mandatory biometric update, after which the child receives normal Aadhaar without any change in the Aadhaar number.
A Second Mandatory Biometric Update at Age 15
The biometric process does not end at five.
UIDAI states that when an Aadhaar number holder reaches 15 years of age, all biometrics, photograph, fingerprints and both iris scans, should again be furnished for an update. This second mandatory biometric update is also free when performed once between ages 15 and 17.
The Aadhaar Handbook 2026 also identifies the updates at ages five and 15 as the two mandatory biometric updates for children and states that the Aadhaar number remains the same.
2026 Update: Mandatory Biometric Update Is Free for Children
There is also an important current fee-related update.
UIDAI states that the first mandatory biometric update is free when carried out once between 5 and 7 years, while the second is free when carried out once between 15 and 17 years. UIDAI’s current website further states that mandatory biometric updates for children aged 5–17 are free until September 30, 2026.
India Post also lists the applicable free biometric-update provisions for children through its Aadhaar enrolment and update centres.
2026 Spotlight: Blue Aadhaar Enrolment at the Doorstep
Another development has brought renewed attention to Baal Aadhaar in 2026. India Post Payments Bank (IPPB), acting as a UIDAI registrar, provides Child Enrolment Lite Client (CELC) services for children below five.
According to IPPB, the service allows child enrolment through a doorstep facility. The process captures the child’s photograph and demographic details, along with biometric authentication of the parent and operator. IPPB says the service is currently available at selected Post Offices and carries no service charge. The Department of Posts has also stated that its postal network provides child Aadhaar enrolment services for children under five.
Reports published in July 2026 highlighted the doorstep Blue Aadhaar facility, while noting that it is not available across all areas and depends on locations where the relevant IPPB and India Post Aadhaar enrolment service is available.
| Feature | Blue Aadhaar / Baal Aadhaar | Normal Aadhaar after biometric update |
| Age at initial enrolment | Below 5 years | After mandatory biometric update |
| Fingerprints at initial enrolment | Not captured | Captured |
| Iris at initial enrolment | Not captured | Captured |
| Child’s photograph | Captured | Updated |
| Aadhaar number | Assigned to child | Same number retained |
| Mandatory biometric update | At age 5 | Again at age 15 |
What Parents Need to Know About Baal Aadhaar
The central distinction between Blue Aadhaar and normal Aadhaar is therefore linked to the child’s age and biometric enrolment process. A child below five can be enrolled without providing fingerprints and iris scans. Once the child reaches five, the mandatory biometric update records the required biometrics while retaining the original Aadhaar number. A second update is required at 15.
The 2026 doorstep enrolment facility through IPPB and India Post provides an additional route for eligible children in selected areas, while parents should verify whether the service is available in their locality before requesting it.
Understanding the Soul’s True Identity
An Aadhaar card gives a person an identity in the material world, but spiritual knowledge raises a deeper question about the true identity of the soul.
The teachings of Tatvdarshi Sant Rampal Ji Maharaj encourage seekers to understand where the soul comes from, where it goes after death, why human beings experience birth and death, who the Supreme God is, and what the purpose of human life is. Our present identity, such as our name, family, religion or place of birth, belongs to this temporary human existence. To explore these deeper questions, readers can listen to the spiritual discourses of Tatvdarshi Sant Rampal Ji Maharaj.
