Frequently Asked Questions

In District of Columbia, the process is known as trade name registration. The procedure is handled by the Department of Consumer and Regulatory Affairs.

Useful information:

  • A trade name is separate from the corporate name, these are viewed as two separate entities in District of Columbia.
  • Trade name registration is obligatory for all LLCs, corporations, sole proprietorship entities, general partnerships and other kinds of organizations.
  • Online filing is possible to simplify the process but you’ll have to meet certain requirements in advance.

To register your business name, you’ll need to put together a portfolio of documents and you’ll also have to meet certain conditions:

Finding out that the business name you want has already been taken can be incredibly disappointing. Always do a check of registered entities to make sure your idea hasn’t been already filed by somebody else. If this is the case, you’ll need to do the following:

  • For LLCs and corporations, there’s a requirement for the selection of a business name that’s different and distinguishable from the names already on file. You can’t just modify the idea slightly and still hope for business entity registration.
  • You can opt for a preventative measure before you register the business. If you spot a name that you like and you’re afraid that somebody is going to take it, you can reserve the name for a period of 120 days.

Both from a legal and from a business point of view, opting for a name that’s unique will be the most beneficial choice. Do a brainstorming session and try to produce a couple of versions that are distinctly different from each other. This way, you’ll get to register a title that you like and that’s representative of your business.
