WhatsApp Compliance in Greece
A practical overview of the rules that affect WhatsApp messaging and marketing in Greece, with a checklist before you launch.
Key Rules for WhatsApp in Greece
WhatsApp Business API campaigns to customers in Greece need opt-in consent under Law 3471/2006 and the GDPR, in addition to Meta's business and commerce 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
The Hellenic Data Protection Authority enforces the GDPR, including cookie consent.
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 +30 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Greece follows the Europe/Athens time zone (UTC+03:00 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 Athens, customers commonly use Greek, with English. 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 Greece
Greece has high mobile use, and Viber is unusually popular alongside Messenger and WhatsApp. SMS is used for appointment reminders, deliveries and bank codes.
Card payments grew rapidly after the 2015 capital controls, and IRIS instant payments are now used for transfers. Tourism dominates the summer economy, so many businesses market in English and other visitor languages from April to October. Easter, the August holidays and Christmas shape domestic demand.
Greece's economy depends heavily on tourism, which brings over 30 million visitors a year to the islands, Athens and Thessaloniki, and on shipping: Greek owners control one of the largest merchant fleets in the world. Agriculture (olive oil, feta, fruit) and a growing technology scene add to this. The standard VAT rate is 24%. Law 3471/2006 requires consent for electronic marketing, supervised by the Hellenic Data Protection Authority. Many Greeks celebrate name days as well as birthdays, which gives retailers extra occasions for greetings and offers.
Regulators, Registers and Practical Rules in Greece
In Greece, the Hellenic Data Protection Authority enforces the GDPR and Law 4624/2019, and the Hellenic Telecommunications and Post Commission (EETT) regulates telecoms. Law 3471/2006 requires prior consent for marketing by SMS, email and automated calls, and live marketing calls must respect the opt-out registers held by operators (the "Article 11" register). Cosmote, Vodafone and Nova are the operators.
Messages should be in Greek; English is widely understood in tourism. The tourist season from May to October dominates hospitality.
WhatsApp and Viber are both popular in Greece.
In practice, Greek businesses use Viber and WhatsApp alongside SMS, and many customers prefer Viber for messages from local companies.
