Just got this call and did not answer. I tried calling back because my mom is visiting LA and the call never when through so looked up the number to be sure. Thanks 800 notes! I then googled this and the IRS has issued a warning for phone calls exactly like this - http://www.irs.gov/uac/Newsroom/Phone-Scams-C ... 5-Filing-Season

Once a week for the last 3 weeks phone showed missed call from this number. Don't know anyone in this area code and I didn't call back to find out who was calling. On my ignore list now.
