FYI - the phone number you quoted above for Experian is incorrect. The correct number is 1-888-397-3742. I called the number you quoted, and ended up with a very annoying automated telephone questionnaire that told me I qualified for a free Caribbean cruise and some free system that alerts somebody if I fall and can't get up.
I am not an Anthem customer, but seeing that I very rarely apply for anything that would require a credit check, have decided to place a credit freeze on all 3 of my accounts. This morning, I accessed my free credit report from Experian, ensured that there was nothing untoward on it, and froze it. For some reason, they were unable to do the credit freeze online, so I did it over the phone.
I'll check and freeze my accounts with the other 2 bureaus in good course.
Thank you sheehs1 for starting this thread.
