Numbered company: A numbered company is a corporation, most commonly found in Canada, given a generic name based on its sequentially-assigned corporation number.  For instance, an entity incorporated under the Canada Business Corporations Act and assigned the corporation number 1234567 would be entitled to register "1234567 Canada Inc." as its legal name.  Similarly, in Australia, a company assigned the Australian Company Number 123 456 789 upon registration can have its legal name as "123 456 789 Pty Ltd".

Legal name: Legal name is the name that identifies a person for legal, administrative and other official purposes.  A person's first legal name generally is the name of the person that was given for the purpose of registration of the birth and which then appears on a birth certificate (see "birth name"), but may change subsequently.  Most jurisdictions require the use of a legal name for all legal and administrative purposes, and some jurisdictions permit or require a name change to be recorded at marriage.  The legal name may need to be used on various government issued documents (e.g., a court order).  The term is also used when an individual changes his/her first or full name, typically after reaching a certain legal age (usually eighteen or over, though it can be as low as fourteen in several European nations).
