Many a time customers wish to change the bank but are unable to do so because of standing instructions for credit/debit to the account. If there is change in the bank without bank account number portability, customers would be put to a lot of inconvenience in the matter of banks acting on their instructions and there would be endless correspondence with the bank. Hence, it is better for us to wait till the account portability becomes possible with the completion of the issue of UIDs There is so much uncertainty now about when the issue of UIDs would get completed or whether it would get completed at all in a person's lifetime!!
