Registering a Business Name

Where an individual or company is trading in Ireland under anything other than their own natural name, they must register the name with The Companies Registration Office.

The Companies Registration Office (CRO) is the central repository of public statutory information on Irish companies and business names.


To register a business name, the place of business address must be in Ireland.

Application Process

Business names can be registered online using CORE (Companies Online Registration Environment).

To register online you first need to setup an account with CORE at https://core.cro.ie.

A step by step guide on the process is available here. Please note the process currently requires the users to physically print, sign and return a document to the CRO.

The fee for online registration is €20.

Please Note: The CRO does not check proposed business names against names on the registers of companies, business names or trademarks. You are, therefore, advised to investigate the possibility of others having rights in the name you propose to use before incurring expenditure in stationery, etc. Applicants are advised to check those registers to ensure the proposed business name does not conflict with a company name or trade mark since any person claiming to have a right to that name could take an infringement action or a passing off action to defend his/her interest. You can check the register of companies and register of business names free of charge at www.cro.ie. The search facility provides round the clock access to company/business information.

Postal applications are also accepted.
