Who called from 21476425

I have never had a call with only 8 digits.  I got a call from this number today.  As usual I didn't answer and no message was left.  Caller ID listed number as 2-147-6425.  What's up with this?

Got a call from 21476425; to my cell phone. I'm on the do not call registry. This is such a weird number. I didn't pick up.

Unknown number, left no message

got the same call. Anyone sign up for a bank account or cc recently?

I too just got a call from this 214764525 number at 3:46pm (Eastern). I didn't answer due the odd look of the #. No voicemail left either.
