Not sure if this is the right forum, I'll not be offended if somebody moves it...
I have an informal company/organisation name that I use from time to time as a 'brand name' for various activities, though it is very informal... not registered at Companies House, and not used for banking etc. Occasionally I make a few dollars, such as from Google Ads or my iPhone Apps (all fully declared for tax!) for example, which I bank under my personal accounts but for which I like to perceived as having a company identity.
It's been pointed out to me that I could make things more formal, and maybe open a few doors, by registering for what's called a DUNS number, which is an International database of all known company names. I had never heard of DUNS numbers until today. I wonder if any learned members may have come across them, and whether there is any downside to registering?
