Resale IDs, State IDs and D&Bs - Do I need them all?

Hello all. I am new to buying from wholesalers and they ask for federal id# resale #, D&B # and state id #. Do I need all of these? Where do I get them? How much are they? Thank you for any help

If your in the USA go to your local courthouse.Ask the clerk of the court where to go,and which forms you need,shouldnt take more than 15 minutes.Some states its free to have resell license and others it costs 50.00$..search yahoo ' resell license' 'business resell license'You should get a website explaining all you need.They will also do it all for you for a fee.

If you are in the States, just go to your home states website and somewhere on that site you will be able to fill out a form for you resell license/tax id. It only takes about 5 minutes to do it. Fees range from free to about 25 dollars is the highest I have found. My particular state charges 15 dollars...
