WhatsApp Compliance in Ireland
A practical overview of the rules that affect WhatsApp messaging and marketing in Ireland, with a checklist before you launch.
Key Rules for WhatsApp in Ireland
WhatsApp Business API campaigns to Irish customers should be consent-based under the ePrivacy Regulations and GDPR, alongside Meta's policies.
In Europe, WhatsApp marketing is treated like other electronic marketing: you need a lawful basis, usually consent, and you must be transparent about how contact data is used under GDPR or UK GDPR.
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
- Use the official WhatsApp Business Platform rather than personal or modified apps, which risk bans.
- Collect opt-in that clearly mentions WhatsApp and your business name, and store a record of it.
- Choose the correct template category and keep utility messages free of promotions.
- Respond within the 24-hour customer service window where possible, and use approved templates outside it.
- Honour opt-outs and blocks, and watch your quality rating in WhatsApp Manager.
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 WhatsApp 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.
Regulators, Registers and Practical Rules in Ireland
Ireland's ComReg and the DPC oversee marketing rules.
Ireland's S.I. 336 of 2011 requires prior consent for marketing SMS and email to individuals, and the Data Protection Commission enforces it with prosecutions. ComReg runs the National Directory Database opt-out. Vodafone, Three and Eir are the operators.
