Dispute the current name and current address by calling/mailing/uploading (whichever you prefer) DL and Utility Bill to each CRA. I just did this last month and EQ was the only one that replied "send larger copies of I.D. and Utility Bill". they had the Name and current address fixed the same day i received that letter so i never sent the docs.
As far as previous addresses, i am sending a request to remove all that aren't tied to TL's on my reports. reason: It leaves me much more open to IDTheft.
"Does it hurt anything" not your score (i dont think). But one of the things lenders look for is "how long at current address" so i think having all the prior (and wrong) addresses listed suggests risk. I think the CRA's normally like to list your current and past 2 addresses on each report. I'll keep you posted when i hear anything back from TU/EX/EQ on my latest disputes.
My reporting addresses include 4 of the same (spelled different), all my past real addy's, my parents, my siblings, my ex's. etc.
i just copied this from Barclays website...
A great many factors go into determining how much credit you are granted, and what it will cost over time.
To make this determination, a financial institution assesses your risk by using the following factors:
I would clean it up for my personal satisfaction. They'll probably ask you to provide a legal ID to make some changes, like your name for example. The addresses are quite easy to remove with an online dispute and deleting them.
Good luck.
