Hello,
Welcome to VAF. If you use the search button here at the top you will note that there are many threads about registering a company name. The entire VAF
Business Development category reviews from soup to nuts what is needed to register a business, apply for the EIN, etc. I recommend that you take a moment to search through.
Your profile doesn't indicate what state you are from but generally most businesses are registered with their state's Department of Labor or Commerce. You might want to Google 'your state name - how to register a business'. Chances are you will be taken to your state's site giving instructions on registration.
The Small Business Administration has a great website on registering a name

Your local government may also want you to register with the county or the city in which you live. So I would check your local government website as well.
You can request the TAX ID through the IRS. Here is the IRS' site for small business owners and can answer your questions about obtaining an EIN

You may also want to copyright your company name but first check
TESS (Trademark Electronic Search System) to make sure no one has registered that name in your state. Here is the copyright government site

Best of luck!
Post back if you need any additional assistance.
