Daley Center Chicago Birth Certificate
Getting the certificate as a child : In almost all countries around the world, a child is registered immediately after birth or within the first six months. Registration is done by the child's parents or by designated guardians. The constitution goes further to stipulate that even if the child dies at birth, he/she must be registered.
A birth certificate copy is still an official document, printed on official paper, and can be identified as a proper document. A photocopy is not necessarily accepted by any or all government entities, and in most cases will be refused. In today's world, it's increasingly hard to do anything that is government run without your identification papers.
