SMS Compliance in Denmark
A practical overview of the rules that affect SMS messaging and marketing in Denmark, with a checklist before you launch.
Key Rules for SMS in Denmark
Section 10 of the Danish Marketing Practices Act requires prior consent for marketing by SMS, email and automated calls, with a limited exception for existing customers; the Consumer Ombudsman enforces it and Datatilsynet supervises the GDPR.
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
Datatilsynet enforces the GDPR in Denmark, and cookie consent must be informed and freely given.
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 +45 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Denmark follows the Europe/Copenhagen 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 Copenhagen, customers commonly use Danish, 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 Denmark
Denmark is highly digital: MobilePay is used by most Danes for payments between people and in shops, and MitID is the national digital identity. SMS is used for appointment reminders and authentication, and Messenger is widely used for chat.
Danes expect informal, trustworthy communication and dislike aggressive sales tactics. The Danish Marketing Practices Act requires prior consent for electronic marketing. Christmas lunches (julefrokost), Black Friday and the summer holiday in July shape demand.
Denmark's economy includes world-leading companies such as Novo Nordisk (pharmaceuticals), Maersk (shipping), Vestas and Ørsted (wind energy), Carlsberg and LEGO, along with a strong design and food sector. VAT is 25% on almost everything, and the currency is the Danish krone. Section 10 of the Danish Marketing Practices Act bans unsolicited electronic marketing such as SMS and email without prior consent, and the Consumer Ombudsman enforces it actively. Payments run on MobilePay and the Dankort debit card, and logins use MitID.
Regulators, Registers and Practical Rules in Denmark
Denmark's Marketing Practices Act bans unsolicited electronic marketing without prior consent, the Danish Data Protection Agency (Datatilsynet) enforces the GDPR, and the Robinson list held by the CPR register lets people refuse direct marketing. TDC, Telenor, Telia and 3 are the operators. MobilePay is the dominant mobile payment.
Operators and aggregators expect sender names to identify the business clearly. The Danish Consumer Ombudsman actively enforces the spam rules and has published guidance on consent for SMS marketing. Messages should be in Danish, although English is widely understood.
Use Danish sender names.
General guidance, not legal advice. Check current rules with the regulator or a local adviser before launch.
Advertising Alongside Messaging
The Consumer Ombudsman's guidance requires clear labelling of advertising, including influencer and social media posts.
This guide is general information, not legal advice, and reflects our understanding as of October 2026. Rules change, so we check current requirements for Denmark before every launch.

SMS in Denmark: FAQs
Do I need consent to send marketing SMS messages in Denmark?
In most cases, yes, or at least an existing customer relationship and a clear opt-out.

Sender ID rules vary by country and operator. Some countries require pre-registration of alphanumeric sender IDs, others only allow numeric senders. We confirm the current requirement before launch.
