I recently changed my Geico policy details.  I have gotten a half-dozen or so calls from 800-123-1234.  I did not answer; no message was left.

I have Geico, have not moved and it is my office line.  Didn't answer it because it was an unusual sequence of numbers.  They left no message.  If it is important, they should leave a message.  If they don't, I feel it is a scam just waisting my time.

I received call from this number at 2.45pm EST. I was on another call & hoping to get voice mail and then reply. No voice mail.

yeah, got a call from this # 6-19-08 @ 1843.  funny thing is that i do have geico ins and i did recently change addresses.  but i did not answer and no VM was left.

I do not have Geico, nor have I moved, but I was called by this number.

I just got a call. It's GEICO automatic message. Based on the voice mail I got: they check the social security and detect address change. It's a reminder to change address online/ by phone if you have not done so.
