D&B Number

[Matt S]

New to RE Investing and have been keeping up on the latest financial situation(s) regarding Fannie and Freddie. I already have an LLC set up and would like to start building credit, so in the future I can avoid rules such as the 4 property rule by Fannie Mae. My question is this: when I start to build credit in my LLC, must I have a DB #, if so why? I do have an FEIN# and plan on opening credit with the likes of Staple/Office Depot, Lowes/Home Depot as I understand this is the best first step to building credit. What does the DB # do for me? Thanks.
