You can send One-Way and Two-Way SMS in Ireland.
However, you can't send MMS messages.
Available Sender IDs
You can choose from a few Sender ID options when sending to Ireland.
Registration and fees may apply.
Not sure which one to choose?
See our Sender ID guide or contact support — we're happy to help.
Shared numbers
Shared numbers are free, ready to use, and don’t need registration. Messages will be sent from our pool of local Sender IDs, so the number might be different each time. For one-way messaging, a dedicated number is not required. You can use your own mobile number as the Sender ID, but replies will bypass the ClickSend dashboard and go directly to your mobile number.
Shared numbers are recommended for one-way messaging only.
Dedicated numbers
Send from a trusted, local number. Your messages will always come from a consistent Sender ID, which is perfect for establishing trust and recognition. A dedicated number supports two-way messaging, allowing both outgoing and incoming SMS communication.
To purchase a dedicated number, please contact support. Ensure your account has sufficient credit to cover the monthly fee for smooth processing.
Dedicated number registration usually takes 2-3 weeks.
Registration requirements
When purchasing a dedicated number, you will need to provide:
Business Details: Name, address, and website (must be valid and working for carrier checks).
Contact Details: Email address and phone number (does not need to be Irish).
Intended Use: A brief description of how you plan to use the number, including the types of messages (e.g., marketing, notifications, alerts, 2FA) and 2–3 sample messages.
Compliance Information: Proof of how contacts were acquired (e.g., opt-in landing page URL) and estimated monthly sending volume (inbound and outbound).
Alpha tags
Alpha tags allow you to use your brand name as your Sender ID instead of a number.
To send using an alpha tag, your alpha tag must be registered with ClickSend, and with the local regulator: ComReg. Recipients cannot reply to messages sent using an alpha tag.
From 3 July 2025, alpha tags must be registered with ComReg.
Messages sent from an unregistered alpha tag will be sent as "Likely Scam".
From 3 October 2025, messages sent from an unregistered alpha tag will not be delivered.
How to register:
