SMS Guidelines for Ireland
MCC: 272 Dial Code: 353 Ireland's Commission for Communications Regulation (ComReg) is in the process of implementing mandatory registration for Alphanumeric Sender IDs. Starting from July 3, 2025, all unregistered Alphanumeric Sender IDs will be overwritten with the Sender ID "Likely Scam". From October 3, 2025, all unregistered Alphanumeric Sender IDs will be blocked resulting in messages not reaching the intended recipients. To register it is first necessary for you to register as an Alphanumeric Sender ID owner (SIDO) with ComReg. You can do so here. As part of the process, make sure to select Telnyx as your Participating Aggregator or OPA. Once this step has been completed and you have been registered as an SIDO you are now able to register your own Alphanumeric Sender IDs. NOTE: If you are an ISV or reseller you cannot register Alphanumeric Sender IDs on your clients' behalf. Only the Alphanumeric Sender ID owner can register their respective Alphanumeric Sender IDs. For more information on Alpha Sender ID registration kindly reach out to alpha_sender_id@telnyx.com. Please make sure to always refer to our Acceptable Use Policy for Messaging.
