Unfortunately, there are no clear instructions on how to close a PNC account on PNC's website. You best option is to contact PNC's customer service at 888-762-2265 or visit a local branch (https://apps.pnc.com/locator/#layout=landing). If you already have online access with PNC then you can log into your account and can also send a secure message for more assistance. After getting all the details and closing the account, remember to obtain a written confirmation to keep for your records.
