Well, first of all, they don't affect your score, and this includes the employment info, which once upon a time was calculated in. But the addresses in particular could cause you trouble down the road. When one of the other mods app'd for Discover, they pulled EX, which had a bad address, so they also did a hard on TU just to confirm. Also, your apps could be held up while they try to confirm your correct info.
My addresses were OK, but my employment info was screwed up. I did an online correction with all three, and they mostly got it right, but I wound up having to thrash out the final bit with EQ and EX over the phone.
I would do an online correction of the addresses first, and once they're resolved, clean up the employment info. You might have to send in proof of address, so a fax machine is handy. The reason that I said to do it in two separate steps is that during this process, you can update your full EX and TU reports, checking for softs and so forth, as you are disputing. This will also give you full creditor info, including addresses, if you need them.
