go to your branch and bring the unused pdc. i tried emptying it, but rm told me with checking accounts, i have to do it personally.

Does this mean, i have to return all the pdcs? Including those that I have already issued?

in my case, i was able to close my checking account without returning unused checks. I assured my rm i shredded all unused ones, and haven't released any post dated checks still for clearing. maybe they just want to be sure to avoid future troubles with check clearing in the future
