What date is used for items to be removed from credit report?

It will be removed from your credit report 7 years after they have made contact with the account holder. Example: when they mail you bills, if they don't get it back as return-to-sender, that's a contact because they are assuming that they didn't get it back because that is the address of the account holder.

The same is true with phone calls. If they call and at no point are they told that they have a wrong number, although they may never speak to the person they are asking for, that's a contact.
