Choosing a name

A good business name can help to get your business noticed. Finding a name which stands out in a positive way can make it easier for your customers to remember you.

Some people believe that the best names are those which describe what you do, while others prefer more abstract or made-up names.

A descriptive name can be advantageous because it is informative, but it can also cause problems. Other people will be entitled to use names which are very similar to yours, and it can become difficult to distinguish your business from those of others. For example, if you register the name Blomsterbuketten AS, others will be able to register Blomsterbuketter AS. And if you decide to call yourself Valdres bilsørvis AS, you may find out that Valdres bilservice AS also operates in the same sector.

It is important to consider whether the name will give you the identity you are looking for, and whether it could be confused with the names of other businesses. The name should also be suitable for use on the internet and be available in the channels you want to use.

Requirements concerning enterprise names

An enterprise's name must contain at least three letters from the Norwegian alphabet. The name cannot only consist of the name of a country, county or municipality. Certain special laws impose limitations on the right to use particular terms in an enterprise's name. Examples of words which cannot be used freely are bank, savings bank, pharmacy and stock exchange.

Foretaksnavneloven (in Norwegian only)


In addition, some titles are reserved for individuals and enterprises which possess particular qualifications. Examples of such titles are lawyer, registered auditor and state-authorised auditor, state-authorised estate agent and master.

Find out whether the name is available

At navnesø, you can find out whether the name you want to use is available as a domain name, enterprise name and trademark in a single search. When you register, the following can be a good sequence to follow:

  1. Register the domain name
  2. Register the enterprise name
  3. Register any trademark


It is often more difficult to find a good domain name which is available than it is to find an enterprise name which is available. Once you have found one or more domain names you want to use, you should therefore register them immediately so that you can prevent other people from using them.

If you choose a name which is identical to an enterprise which is already registered in the Register of Business Enterprises, you will have to obtain the consent of the people who own the name and then enclose this consent when you register the enterprise. Thorough preparation will reduce the risk of you having to change your enterprise's name after you have spent time and money establishing a name and logo.

Marketing name

It is possible to use a different name for your business than your official enterprise name. You could for example use this name on signs, as a logo or a domain name, etc. For example, the enterprise Per Holm could register Grillbua as the name of its business. However, the official enterprise name of Per Holm must still be stated on all business documents such as letters, websites and invoices.

You can register marketing names either at the same time as you register the enterprise or later. Whenever you register such names, you must use the Coordinated register notification. The fact that a name has been registered as a marketing name does not prevent other people from registering the name as an enterprise name.

Protecting a name

In order to protect your enterprise name, you can register it in the Register of Business Enterprises. If you have a sole proprietorship, it is the full name, including your surname, which will be protected.

You can also opt to trademark-protect the enterprise name, the domain name or your marketing name.
