how to change aadhya age

A. Hello good evening !! A Birth certificate and Aadhar card are proofs for age. Birth certificate as per the birth details from the hospital and MRO office in the birth city and required details you can apply for birth certificate but once you have taken then no more changes will be done in the name and age. In Aadhar card you can match/alter the birth month or age or other details as per birth certificate by showing as a proof. If you have already taken the birth certificate then you cannot change the age.
