Just got this from the PIA (this is a professional organization primarily for P&C agents; our agency is a member):
Question: How many agents have actually fallen for this?
[ed: probably a lot more than you'd like to think]
As the release points out, Insurance Departments don't contact agents by phone on matters such as these; they're almost always by mail (ie, paper trail). So if you get such a call, keep your Visa number to yourself, and contact your own DOI as soon as possible.
