How to change the permanent address in sons birth certificate

Hai

The address can be changed. But it should be done at the earliest. Its earlier the better n easier. N i think there is a statutory bar if its unchanged after 3 years after enrolment. I will revert u after verifying. Do consult the secretary of birth n death in ur local LSG at the earliest

Hope am upto ur query

Yes, the authorities are correct. The relevance of birth certificate is primarily to the date of birth. Anyhow, you can get the permanent address incorporated. There could be some time and procedure involved. But the child is only four months old.
