Today I received a communication from Ally bank detailing upcoming changes relating to FDIC requirements requiring banks to 'uniquely identify' beneficiaries on accounts to expedite insurance coverage determination in the event of a bank failure. While a quick read of the rule doesn't seem to explicitly require Ally's methodology, they are choosing to utilize social security numbers and/or tax ID's of the beneficiaries for this purpose. As they hadn't previously collected this information (they only required names), they are now requesting affected account holders update their profiles accordingly. Not sure if all other banks will go the same route, but it seems like its the most obvious way to go, so those of you that utilize beneficiary accounts such as P.O.D. accounts be on the lookout. Here is Ally's link as well as the specific FDIC rule:
