If you receive a text message and don’t know who it’s from, don’t delete it. Read it carefully as it may contain important information (such as a helpline number for the company who has sent the message).
If the message comes from a five-digit short code, you can use our online Service Checker [https://servicechecker.comreg.ie/] to find out the name of the service and the name of the company providing that service as well as their contact details.
If the message does not help you to identify the sender, and there is no identifiable short code, call your mobile phone company to see if they have any information on the sender and whether it cost you anything to receive the message.
If you were charged for the text and don’t think you agreed to receive it, contact the premium rate service provider to raise the issue with them.
If the issue is not resolved by the premium rate service provider, contact ComReg. You will need the number that the text message came from and its contents when you make your complaint
