Don't know but My ex, her Mom and a neighbor got a call after midnight the oother night....all with in minutes of one another.

509 is in the State of Washington but the 192 prefix is definately bogus do to the '1' in the 192 isn't a usable number.

We're in California by the way.....

The caller wasn't rude, pushy or selling anything...just looking for a female name.
