## Compliance in Ireland

- **Opt-in:** Required. Marketing SMS needs affirmative consent: an unticked box or a texted keyword, never implied. Existing customers can be messaged about similar products for 12 months after a sale if they were offered an opt-out at the time. Consent to SMS must be separate from consent to email.
- **Opt-out:** Required. Every marketing message must identify you and give a free, simple way to stop, such as 'reply STOP'. Honour opt-outs promptly and before your next send. PureSMS handles this for you: opt-out replies are processed automatically and the number is blocked from further sends, so you're compliant without building anything.
- **Restricted content:** Controlled substances · Gambling · P2p traffic · Political · Religious · Unsolicited promotional
- Gambling content is permitted subject to compliance with all applicable local laws and regulations; legal counsel should be consulted.

### Legislation & penalties

- **[ePrivacy Regulations 2011 (S.I. No. 336/2011)](https://www.irishstatutebook.ie/eli/2011/si/336/made/en/print)** — Regulation 13 requires prior consent for direct marketing by SMS, with a soft opt-in for existing customers within 12 months of a sale. Every message must identify you and offer a free, easy opt-out. Penalty: A criminal offence prosecuted by the Data Protection Commission: up to €5,000 per message on summary conviction, or up to €250,000 on indictment.
- **[GDPR and Data Protection Act 2018](https://www.dataprotection.ie/en/organisations)** — Phone numbers are personal data. You need a lawful basis to use them, must be transparent about how, and must honour objections to direct marketing. Penalty: Up to €20 million or 4% of global annual turnover, whichever is higher.
- **[ComReg SMS Sender ID Registry](https://www.comreg.ie/sms-sender-id-registry/)** — Since 3 October 2025, Irish networks block messages from alphanumeric sender IDs that aren't on ComReg's registry (from 3 July 2025 they were relabelled 'Likely Scam'). Registration is free and first come, first served: register as a Sender ID Owner, then register each sender ID of 3 to 11 characters. Numeric senders are exempt. Penalty: Messages from unregistered alphanumeric sender IDs are blocked.

These rules are what we generally check against, however they may not be up-to-date. We'll always keep you informed of what is needed for each destination throughout any registration process.

## Frequently asked

### Can I use my brand name as the sender ID in Ireland?

Yes, once it's registered on ComReg's SMS Sender ID Registry. Since 3 October 2025 the Irish networks block unregistered alphanumeric sender IDs, so register before you send.

### How do I register a sender ID in Ireland and what does it cost?

Registration is free at senderid.comreg.ie. You first register your organisation as a Sender ID Owner, then apply for each sender ID (3 to 11 characters, at least one letter, no generic words like 'SMS' or 'Verify'). Allow around 10 business days.

### What happens if I send from an unregistered sender ID in Ireland?

The message is blocked by the participating networks. Between July and October 2025 unregistered IDs were delivered with a 'Likely Scam' label; now they don't arrive at all.

### Do I need consent to send marketing SMS in Ireland?

Yes. The ePrivacy Regulations require affirmative opt-in consent, with a soft opt-in for existing customers within 12 months of a sale. Each message must identify you and offer a free opt-out. PureSMS processes opt-out replies automatically and blocks further sends to that number.

Sending marketing SMS without consent is a criminal offence prosecuted by the DPC: up to €5,000 per message on summary conviction or €250,000 on indictment, on top of GDPR fines of up to €20 million or 4% of turnover.

### How do I format Irish mobile numbers?
