Missed a call from this number. No message left.

Called my cell phone... unknown caller from La Habra, CA.  I don't do business with anyone from the "land of fruits and nuts."  So I just blocked this caller.   Curiously, I received a second incoming call not five minutes later with "No Caller ID"... coincidence or not?

First i got a call from 973-943-6812 with the caller id of v208097271400475 @...Did not answer it..Five minutes later got another call from 562-371-4511 with the same caller id..Strange two different area codes but with the same caller id
