thomasj: We use acct no, SSN and DOB to identify telephone callers.
In the past, we tried to include date and amt of last transaction/deposit, however, particularly on joint accts and when debit and ATM card use is prevalent, too many people didnt know this info.
Thus far, no one that supplied us w/acct no, SSN and DOB turned out to be a fraudster.
On change of address, like Brenda, we also dont use the post office change of address notice as a confirmation, but rather as an indication to contact the customer to verify the change. We learned this one the hard way.
Customer had to go to prison, so he gave his business partner (and we later learned sometime paramour) POA to transact business for him while he was in prison. She had the post office change his address, and from there proceeded to steal everything he had. He didnt learn of the theft because (he said), when he didnt receive bank statements, he thought it was a problem w/the prison mail system.
