I'm trying to do is rename a batch of 200+ files as above by pulling the policy number following the word "Policy" found in the document. I'm wondering if I can reference it to a particular line of information in the word document, and how I would do so? I had tried using a macro where it renamed the document with the first line of information on the page, and I simply added a mail merge line (in white font) as the first line so that it would pull this information, but not show in print. Unfortunately it did not work... and am wondering if my first idea might work better. Can anybody help me create a macro where I take a particular line (and tell me how I should reference to a particular point)?
Letter looks like this:
Date
Address 1
Address 2
Address 3
Address 4
Policy XXXXXXXXX
<Body>
Policy number can change in # of characters depending on the type of plan code it is; so I'm not sure how to search something like that with parameters (which is why I'm wondering how to pull an entire line of information to rename the documents within a particular folder).
I also don't want a macro that creates a duplicate file (resulting in two of the same document with different names - as I have read within threads this can cause problems with loop).

Big thanks in advance!
