SMS Compliance in Belgium
A practical overview of the rules that affect SMS messaging and marketing in Belgium, with a checklist before you launch.
Key Rules for SMS in Belgium
Belgium's Code of Economic Law (Book XII) requires prior consent for marketing by SMS and email, with limited exceptions for existing customers, and the GDPR applies; the Data Protection Authority (APD/GBA) enforces privacy 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
The Data Protection Authority (APD/GBA) enforces the GDPR, including strict expectations for 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
- 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 +32 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Belgium follows the Europe/Brussels time zone (UTC+02:00 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 Brussels, customers commonly use French and Dutch, 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 Belgium
Belgium has high smartphone adoption, and WhatsApp and Messenger are the main messaging apps, while SMS is used for appointment reminders, deliveries and bank codes. Campaigns usually need separate Dutch and French versions, and sometimes German, depending on the region.
Bancontact is the dominant payment method online and in shops, and the Payconiq by Bancontact app is popular for mobile payments. Belgian consumers are price-aware and respond to promotions during the regulated sales periods in January and July, Black Friday and Saint Nicholas Day on 6 December. Brussels' EU institutions and international associations make English common in B2B.
Belgium hosts the EU institutions and NATO in Brussels, and the Port of Antwerp-Bruges is the second largest in Europe. Chemicals, pharmaceuticals (Pfizer and GSK vaccine plants), logistics and diamonds are key sectors. Belgium is divided into Dutch-speaking Flanders, French-speaking Wallonia and bilingual Brussels, with a small German-speaking community, so campaigns must use the right language for each region. VAT is 21%, and the 'Do Not Call Me' list lets consumers block telemarketing.
Regulators, Registers and Practical Rules in Belgium
Belgium's Data Protection Authority enforces the GDPR, and BIPT regulates telecoms. The "Do Not Call Me" list must be checked before telemarketing.
Marketing SMS and email need prior consent. Messages should be in French, Dutch or both depending on the region. Bancontact is the most used payment method.
Proximus, Orange Belgium, Telenet and DIGI are the operators.
In practice, Belgian consumers expect to be addressed in their own language, and sending French messages to Flemish customers can harm a brand. Segment contact lists by language preference and region, and keep opt-out wording in the same language as the message.
General guidance, not legal advice. Check current rules with the regulator or a local adviser before launch.
Advertising Alongside Messaging
Advertising follows Belgian consumer law and the Jury for Ethical Practices in Advertising (JEP), which has issued guidance on influencer disclosures.
This guide is general information, not legal advice, and reflects our understanding as of October 2026. Rules change, so we check current requirements for Belgium before every launch.
