Sounds easier to opt out of those mailers entirely. There's a website sponsored by the FTC to do it. But you can only opt out of 5 years online. To do it permanently you must print out and mail in the form.

AFAIK it works but it reeks of bullshit. First its a .com but its what the FTC recommends. It seems like the feds forced the credit companies to make the website and their really upset that your missing all these credit opportunities. Maybe they lower your credit score if you actually fill it out.

I did it years ago. I never noticed any retaliation, but the lack of garage in my mailbox is noticeable. I swear some of those credit cards would send daily letters!

Sure, vendors who already have my information still send me things, but I just call them and get them to remove me from the list. Now the only thing that remains is the political junk mail you can do nothing about.
