I have noticed that in the last several months, crooks have been spoofing phone numbers that start with the same three digits as my cell phone number, so that I'll think it's a "local" call and therefore answer.  Nope.  This number was used to call my cell phone today at 3:48 pm.  I've now blocked it.  Other ones they have called from include 310-569-1994, 310-569-4242, and 310-569-7641.
