What is Blue Aadhaar? How To Apply – Step-By-Step Guide

The Blue Aadhaar card, issued for children under five, is commonly referred to as “Baal Aadhaar.” It’s called “Blue Aadhaar” because of its distinctive blue color.

Aadhaar is more than just a document; it’s a lifeline for accessing government benefits and services. This unique 12-digit number, issued by the UIDAI, contains crucial information like name, address, and date of birth, making it an indispensable part of every citizen’s identity.

Introduction to Blue Aadhaar

Introduced in 2018, the ‘Baal Aadhaar’ card is designed for children under five years of age, distinguishable by its blue colour. It features a unique 12-digit number for children below this age. Unlike adult Aadhaar cards, no biometric data is required initially; the child’s UID is processed based on the demographic information and facial photograph linked with their parents’ UID. However, biometric data must be updated when the child turns five and again at 15, or the card becomes invalid. The biometric data update for teen cardholders is free.
