Yesterday morning I called Equifax to dispute the only two old/former addresses on my report. The rep said they'd do an investigation and they'd let me know the results when the investigation was completed. I didn't really think much of it because how can they verify old addresses?? Well, I just found. There was an Equifax credit watch alert in my mailbox this morning. I checked to see what the alert was for and it shows four accounts that I did not ask to be reinvestigated are now in dispute. Two are bad/old charged off accounts and two are good/current accounts. So, I called right away to find out why they were being investigated. The rep said when someone disputes an address they're required to send out an address verification form to at least four creditors on the report. If any of them say they did send bills to that address then the address will remain. She did make a point to say that the accounts themselves were not in dispute. And all this time I thought they just deleted old addresses on people's say so.
