Caller ID said Tucson, AZ. Let call go to answering machine. No message left. I am also on DNC list. It is not effective due to the amount of aggregate information collected on the internet. If you Google your name, you will see many websites with your personal informatiion available for sale. This information is gathered from public records, often includes location, address, possible relatives, birth month & year, social network posts & much else. There is no longer privacy because of our activities on the internet. Best thing to do is not answer calls from suspicious numbers and block them.
