The District of Columbia TN 1 Trade Name Registration Form is used by businesses operating in the District of Columbia to register their trade name with the Department of Consumer and Regulatory Affairs (DORA). The form allows businesses to declare their trade name to the DORA, which in turn allows the DORA to register the name with the U.S. Patent and Trademark Office. This form is necessary for businesses to be able to legally operate in the District of Columbia. The form is available in two different versions: the standard version, which can be filled out manually, and the online version, which is available through the DORA website. The standard version requires businesses to fill out the form completely and include the filing fee, while the online version requires businesses to provide the trade name, contact information, and a valid credit card for payment. Once the form is completed and submitted, the DORA will review the submission and issue a Certificate of Registration. This document serves as official proof that the trade name has been successfully registered with the DORA.
