Some things I follow
NOTE: A large part of ID theft is physical mail being stolen or low level store clerks who have access to your info. Or via home burglary and records/checks get stolen.
1. Mail never comes to personal physical residence. It goes to a PO BOX. My first name initial and last name only. Non quasi-legal mail, (such as utility payments, bank mail, etc) my last name spelling is slightly different than my true, real, legal name. If my full name is Jeremy Michael Longhouse then my name on 95% of my mail is
J. Longhause
This helps filter obvious "BS mail" (to J Longhause incorrect spelling) from legit mail (court summons, card from grandma, bank statements).
2. FedEx / UPS packages to to my office, they allow it.
3. Credit Card statements reviewed regularly.
4. I have a pre-paid cell, no name on the account (buy it at wal-mart), for non-family, non-close friends cell use. Aka drop car at the dealer, they need a cell number. Restaurant, wait on a table, we will SMS you when your table is ready, etc.
5. When a store (Academy and Best Buy are famous for this) asks for zip code, decline it and decline "you phone number please". Telling them "I live overseas" works well
6. Internet, use HTTPS only for critical banking etc sites. Never wi-fi at public coffee shop etc.
7. Not listed in phone book.
8. Home phone hard-line is VOIP based from local big name cable TV company.
9. Know all my neighbors
10. Keep wallet / credit cards with me at all times
11. If at a restaurant with poor service, etc, pay cash. Don't need waiters jotting down my credit card info plus security code on back.
12. Anti-virus and firewall on all computers. If out of town or vacation, computers and router is unplugged from power outlets. Firefox and Chrome both used. No explorer
13. WPA on router.
14. All computers have password log-on home screens upon power-up
15. Strangers at door, selling stuff, I answer it (to show that a human is home) then I ask for their photo ID, and read their name outloud back to them. "Before I think about buying anything from you I need to see photo ID. We had some issues a while back in this neighborhood with solicitors" "So, you are Joe Smith, nice photo, haha, ok so tell me what you are offering". No ID or evasiveness, police is notified via phone call. The whole neighborhood pretty much practices this. Luckily we don't live in downtown Detroit and our department actually follows up on this. They have the time
16. I never use paper checks, ever. Stopped in ??? 2000, 2002. 10+ years ago
17. ONE credit card, via USAA.
18. If a place needs photo ID "on file" for some reason, I let them copy my passport. NOT my Drivers License.
Good Luck
