Go on line at www.FDIC.gov. In the lower right hand corner is a search button for EDIE-Online Version. This is a fill in the blanks form. You enter each of your accounts at an individual bank. You will add information for each account. It will ask if it is a trust, POD, joint ownership, IRA, etc. After you complete each account, you can add others. When done, it will prepare a report you can print that will spell out just how much FDIC insurance coverage you have for that particular bank.
If you are looking for a little peace of mind about your bank accounts, try it.
