D&B Number is free for Federal Contractors and other special needs. Not sure about other businesses. They call you and sell you subrsciption or some thing for several hundreds of dollars. May be it is free for people who wait. I got it for one of my business about 10+ years and not sure. I am planning to start new business and I'll find out.
Yes, it's definitely free and you usually get it within 30 days of incorporation. You can pay to have the number expedited and you'll have it within 2 weeks. And yes, they will try to upsell you on their products, which isn't necessary needed.
