If you operate a business that trades under a different name to your own or if a limited company, different to the legal name you need to register a business name with the CRO. The process is very quick and simple using the CRO’s core.ie website
First, check on the CRO using company search that the business name you want is not registered. You are responsible for ensuring this as the CRO does not check when you register the business name
Next you need to register on core.ie. The information required is self explanatory. You will also require your PPS number.
When you have registered on core.ie, login and select “File a form”, “Register a business name”. When you have completed all the steps you need to pay a ?20 fee. You print off the pdf, sign and return to the CRO. The process is usually very quick.
