SMS Compliance in Ireland
A practical overview of the rules that affect SMS messaging and marketing in Ireland, with a checklist before you launch.
Key Rules for SMS in Ireland
Marketing SMS in Ireland is governed by the ePrivacy Regulations (S.I. No. 336 of 2011) and the GDPR, which require prior consent (with a limited exception for existing customers), sender identification and an opt-out in every message. The Data Protection Commission enforces these rules.
Across the EU and the UK, the ePrivacy rules (implemented through national laws, and PECR in the UK) generally require prior consent before sending marketing texts to individuals, with a limited 'soft opt-in' for existing customers buying similar products. GDPR or UK GDPR then governs how the contact data itself is handled.
Data Protection
Irish websites must comply with the GDPR and ePrivacy Regulations, including consent for non-essential cookies; the Data Protection Commission is also the lead EU regulator for many global tech companies based in Dublin.
Keep a record of how each contact was collected, what they agreed to and when, and make it easy for them to withdraw consent.
Practical Checklist
- Collect and record consent (or confirm an existing customer relationship) before sending, with the date and source.
- Use a registered sender ID or number that recipients can recognise as your business.
- Identify your business in every message and keep promotional and service messages separate.
- Give a simple way to opt out of marketing and process opt-outs quickly across all your systems.
- Send in the recipient's local daytime hours and keep frequency reasonable.
Contact data
Format numbers in international E.164 format with the +353 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Ireland follows the Europe/Dublin time zone (UTC+01:00 in October 2026). The usual working week is Monday to Friday. Schedule SMS campaigns for the recipient's local daytime hours, avoid public holidays and religious observances that matter to your audience, and convert send times from IST before scheduling.
In Dublin, customers commonly use English and Irish. Messages in the customer's preferred language usually perform better, but check how local-language text affects character counts (for SMS) and template approval (for WhatsApp).
Digital Habits and Channels in Ireland
Ireland has high smartphone adoption, and WhatsApp is the dominant messaging app, while SMS is widely used for appointment reminders, deliveries and bank codes. Alphanumeric sender IDs are supported but must be registered on ComReg's SMS Sender ID Registry, launched in June 2025; since 3 October 2025 texts from unregistered sender IDs are blocked before they reach Irish phones.
Contactless card payments and Revolut are widespread, and many people use the Revolut app for splitting bills. Many multinational technology and pharmaceutical companies have European headquarters in Ireland, so B2B audiences are international. Key consumer dates include St Patrick's Day, the Leaving Cert results in August, Black Friday and Christmas, and prices are shown including VAT.
Ireland hosts the European headquarters of many US technology and pharmaceutical companies, including Google, Meta, Apple, Pfizer and Intel, which gives it a large international workforce. VAT is 23% at the standard rate. ePrivacy rules under S.I. 336 of 2011 require prior consent for marketing SMS and email to individuals, and the Data Protection Commission, based in Dublin, is the lead EU regulator for many tech companies.
