# **Ireland Sender ID — Registration & Requirements**

## **Overview**

The Commission for Communications Regulation (ComReg) in Ireland has introduced a **Sender ID Registry** to protect consumers from fraudulent SMS. All alphanumeric sender IDs must be registered to continue sending SMS to Irish mobile users.

The new rules include phased enforcement:

* **From 3 July 2025** – Messages sent from unregistered sender IDs may be flagged as *“Likely Scam”*.
* **From 3 October 2025** – Messages sent from unregistered sender IDs may be **blocked entirely**.

## **Sender ID Requirements**

When registering a sender ID in Ireland, the following rules apply:

* Must be **alphanumeric** (cannot be numeric-only).
* Length: **3–11 characters**.
* Must contain **at least one letter**.
* Cannot be generic terms (e.g., “SMS”, “Doctor”, “Verify”).
* Cannot contain offensive, obscene, or sensitive words.
* No leading, trailing spaces.
* Only permitted characters may be used (A–Z, a–z, 0–9, and limited special characters).
* Must be **unique** — if your preferred sender ID is already registered, you may need to choose an alternative.
