I already put a security freeze on both my and the wife's credit at experian, transunion, and innovis. I couldn't do equifax because shockingly the website refuses to place one but I'm sure it will allow me to sign up for the $19.95/month lock option and the phone system is so overloaded I can't get through even to the "All of our representative is busy" spiel. Seriously, it's been a long time since I heard a busy signal. They do have the option of putting on a freeze by mail but they want a copy of some form of government ID and I definitely don't want them to give them any additional information.
I will be sending them the bill for the credit freezes at the other agencies however.
