I need to scrub this list before I skip trace it and wanted to reach out for some help/advice/direction.  

Somehow I think that the old scrub and dust isn't going to cut it any more?

The kind of morons you see proudly wearing their scrubs and standing in the street to protest those protesters trying to reopen. 

@Mason Hickman I believe that TLO and IDI do scrub against the DNC list.  

Just don't scrub the finish with Bon Ami and you'll be fine for many years.

I have been looking to see how to scrub a list of numbers to see if they are on the do not call list. 

@Kenny OliverIf you plan on calling for a while you can find programs out there that scrub the DNC list.

You don't want to use abrasives like Comet or Soft Scrub on them. 

For example is is a Zillow listing data scrub or from the apartment owner surveys, etc.I love the report, but it would be helpful for me if there was a way to get more granularity.

Skip trace the owners, drive by the home to see if it is vacant & either contact them on on social media or door knock.. of course you can code call too.. but make you sure you scrub the numbers.
