If your ideal business name is already in use, you may have to come up with a new one entirely. While it may be tempting to try to use a slightly changed version of the name, there are certain articles in business names that are disregarded, such as “The” and words that may be at the end of the name, such as “Limited” or “Company”.

Furthermore, some parts of a name are considered the same no matter how they look, such as “and” and “&”.

If you are uncertain whether or not your name is unique enough, you can also seek out advice from the Registrar on whether or not the name will be accepted on an application. This can avoid having to go through the process of sending multiple applications before one is approved. You can find the address to write to on the Guideline on Registration of Company Names document.
