I received a call on my cell phone from this same number.  The recording said it was from 'Alameda County'.  Is this legitimate?

Received a call from this number at 11:00 pm. The caller left a prerecorded message utilizing my name. When I tried to return the call, but there was a "not in service" message.

I also  received a prerecorded message utilizing my name on my phone and also on my husband's phone from this number. The call came through at midnight tonight.
