Company letterheads – your legal obligations


7 April 2014

A letterhead makes correspondence with your customers more professional, adds credibility to the text of the document and also reinforces your companies brand image. It is such an important marketing material to have.

Surprisingly, I see a lot of letterheads that are not professionally designed and some of these don’t even include a companies basic legal obligations.

Many countries have legal requirements for including registration numbers and full company names. In Australia a companies ACN or ABN should appear on letterheads as this is a public document.

It is not a legal requirement to have contact details on your letterhead but is a necessity for people to contact you.

A companies ACN or ABN doesn’t need to appear on the following:

Business cards, with compliments slips, advertisements that promote the company and its products or services in general.

As with most laws there are penalties for non-compliance.

We ensure that all of the letterheads we design include an ACN or ABN. We also create a Microsoft Word template which ensures that all your documents remain consistent with their layout, style and branding.
