If you are a recently qualified member and enrolled recently,and if you wish to attend Convocations, then you will get at that time only. If you don't want to attend the convocations, you will get one more chance to attend convocations (Round-II). Only after that you will get the certificates by post. (From my experience)
If you are already enrolled as a member, then you may write a letter to the regional ICAI office for getting the CoP by post.
