Ireland Business Name Search

Getting Started

Before searching the Ireland Business Name Database, you can save time by making sure your business name is unique and distinguishable from other existing business entities within the Ireland business name database. We suggest coming with a few name ideas in-mind in case any are unavailable. You can find the company name guidelines on the Company Name page of the Companies Refistration Office website.

Contacting the Companies registration office via phone or email is completely free.

However, before doing that you can also make use of the Company Search Facility. This page will allow you to search for names that might have anything in common with the name you’re hoping to use. Because this page only searches for businesses that are already in existence, you may need to also take a look at the Register of Business Names as well as the Trade Mark Register to make sure your name is fully unique.

If your ideal business name is already in use, it’s likely that your business registration application will be denied. It is because of this that it’s important to make sure you search through the reserved business names as well as those already registered to make sure your business name isn’t too similar.

The following tips can aid you in choosing a suitable business name:

(a) Some words, like “Bank”, “University”, and “Society” can only be used with special permissions.

(b) If you want to use a name that is similar to the name of another business, it’s a good idea to gain their consent before you apply. That way, you can be assured they won’t write in with an objection after your name has been approved.

(c) If you are ordered to change the name of your business, you have to do so within six weeks.
