If you’re in the United States, you might have to look at several agencies and institutions like the SBA or Small Business Association, or at the U.S. Securities and Exchange Commission. There are also state registries in every state that you can refer to.
If you’re based in the UK, you can get information about a company by accessing Companies House, which is UK’s public authority that is in charge of handling and managing the registration of companies. You can get information such as: a company’s registered address and the date it was incorporated, the officers of that company, and other details for free.
If you’re thinking of setting up a company in the UK, you will need assistance in taking care of the process of registering your company with Companies House.
