Most people just need one Business Registration Certificate for their LLC. This is because their LLC has one primary business activity that takes place at one location.
For example:
Linda owns Summit LLC and operates the business from home. She offers life coaching services and meets with her clients online. Linda only needs 1 Business Registration Certificate because she is only engaging in one type of business activity at one location.
However, you will need an additional Business Registration Certificate if your LLC is doing business at an additional location or has an additional activity.
For example:
Carl and Marvin own a landscaping business called CM Yards LLC. Carl runs one location of CM Yards LLC in Charleston. Marvin runs the second location of CM Yards LLC in Morgantown. That means CM Yards LLC needs to get 2 Business Registration Certificates: one for the Charleston office and another for the Morgantown office.
Mark and Jen (husband and wife) own Jolly Math LLC. Jolly Math LLC operates out of a single location in Wheeling. They each run separate businesses under the LLC, but work in the same office. Mark runs his accounting business and Jen is a financial consultant. Jen and Mark need to get 2 Business Registration Certificates: one for the accounting business and another one for the consulting business, even though they are both at the same address.
