Section 12 of the Companies Act of 2013 states that all businesses, including LLPs, must have a registered office at the time or within 30 days of registration. The primary place of business for a corporation or LLP is its registered office address. The Ministry of Corporate Affairs (MCA) sends formal letters to that location. Therefore, the RoC or MCA must be notified of any change in registered office's address.
A business may have several locations, including a corporate office, a branch office, an administrative office, and much more. However, the MCA should only be informed of the registered office address. There is no requirement to notify the RoC or MCA about the formation or modification of the address of the company's additional offices.
