In terms of the Companies Act, 2008, a company may be registered with or without a company name. When a company is registered without a reserved name, its registration number automatically becomes the company name. This is the quickest way to register a company.
Such a company may transact with a trading (business) name, or may apply to add a reserved name at a later stage. In this case, the company will need to first reserve a name and then apply for a name change, which constitutes a change to its Memorandum of Incorporation (MOI).
