I am registered as a sole proprietor and have an EIN. I did not go for the LLC as being the only one in the company, it gave me no extra protection from any liability, so I went along with the SP.
When I applied for my business Chase CC, I tried to do so without my personal credit being used. Nope, they were not having it. If I remember correctly, they were more interested in my SS# then my EIN#.
Before I called for that CC, I thought it would be a bit difficult to get since the business was new and had no credit history, but, apparently, my having almost 20 years of credit on file, made it a simple 5 minute process.
Another attempt to shield my personal life from my business venture gone awry. The card has my business name as well as my own name.
I think I remember I did not want to order one for my husband.
The SBDC guy told me if I put my husband's name on the business, he wouldn't qualify for unemployment benefits, since technically he would not be unemployed should he lose his job, he was still 'employed' with my company.
My original question leading to this comment was to find out what would happen if I build a successful company and die. Should I will it to my husband, or set something official up that it stays with the family, or would it be better to add his name to the company.
I found that to be an interesting news piece. Needless to say, he is not on the company paperwork, and now I can't remember if I ordered him a CC. I wonder if that could come into play. This means anther call to SBDC,

Good luck with all your credit needs. Mine are simple for this and my other business, but this post has my wondering if I need a Dun #. I would think not, but now I will read up more on it.
Good post, and my situation is most similar to Lou's, simple credit - done simply.
