There are 3 categories of business to consider.
COMPANIES
This is likely the most common category that needs to be considered. Companies (including private, personal liability and public companies) need to contain the following information on their letterheads:
The full name of the company
Its place of registration
Its registration number
The address of its registered office
The address of its principal place of business (if it is different to the registered address)
With companies you do not need to include the names of the directors on the letterhead; however, you may elect to name your directors, and if you do, you are required to name all the directors.
Let’s take a look at the last two categories.
PARTNERSHIP
Partnerships must include the following information on their letterheads:
The names of all partners
The address of the principal place of business
If there are too many partners to including on the letterhead, you may indicate, on the letterhead, where a comprehensive list of the partner may be found (e.g. a website link).
SOLE PROPRIETOR
Sole proprietors must include the following information on their on all letterheads:
The Sole Proprietor’s name
The address of their principal place of business.
Often a business will “trade” under a different name to its actual name (i.e. a “trading as” name); if a business uses a different name to trade, the actual name of the business must also be recorded on the letterhead.
The above information does not need to go in the heading of the page but it must be somewhere on the page.
It is not a requirement to include all the companies contact details (e.g. telephone; fax number, email; website; etc); however, it is certainly a good idea to include this information.
The above information should also be on your invoices, receipts, and order forms.
