Caller identified herself as representing Fairfax County regarding a credit issue. The number was identified by Sprint as originating in Arlington County. Asked me to "verify" my SSN, which I declined to do, advising I don't give out financial info to unknown callers on the phone.
She responded that she had "identified" herself so I shouldn't challenge her.
I responded that I could call her up and "identify" myself as Santa Claus.
