PAN card is personal identification and is issued to persons, not to any agency,
what you want to say by "bulk" as a person can not get more then one ( two in case of HUF+ individual), so the question of bulk does not apply anywhere in pan card issue.
No such TATKAL SCHEME am aware of........but if u need to urgently quote your pan no then u can give the acknowledment no which will given to u instantly after applying for Pan card......hope his helps....
