SMS Compliance in Finland
A practical overview of the rules that affect SMS messaging and marketing in Finland, with a checklist before you launch.
Key Rules for SMS in Finland
Finland's Act on Electronic Communications Services requires prior consent for direct marketing by SMS and email to individuals, with an existing-customer exception; the Data Protection Ombudsman 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
The Data Protection Ombudsman enforces the GDPR, and Traficom's guidance covers 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 +358 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Finland follows the Europe/Helsinki time zone (UTC+03:00 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 Helsinki, customers commonly use Finnish and Swedish, 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 Finland
Finland has very high mobile data use, with unlimited mobile data plans common. WhatsApp is the dominant messaging app, and SMS is used for transactional messages and authentication, while MobilePay is a popular mobile payment app.
Finns value concise, factual and honest communication and dislike exaggeration. Strong online banking identification is used for logins and payments. Midsummer, the July holiday period and Christmas are key dates, and Black Friday has become important.
Finland's economy is built on technology, forestry and engineering: Nokia, paper and pulp companies such as UPM and Stora Enso, Kone lifts and mobile game studios such as Supercell and Rovio. Finns use very large amounts of mobile data, helped by affordable unlimited data plans from Elisa, Telia and DNA. Finnish and Swedish are both official languages, and many companies publish Swedish versions for the coastal regions. The standard VAT rate rose to 25.5% in September 2024. MobilePay and online bank identification are widely used for payments and logins.
Regulators, Registers and Practical Rules in Finland
Finland's Information Society Code requires consent for electronic marketing to consumers, the Data Protection Ombudsman enforces the GDPR, and Traficom regulates telecoms. Elisa, Telia and DNA are the operators.
Messages should be in Finnish, with Swedish for the Swedish-speaking minority. MobilePay is widely used for payments.
The Finnish Transport and Communications Agency Traficom also runs anti-spoofing measures that block calls and SMS with fake Finnish numbers or sender names, so sender details must be genuine.
In practice, Finns expect messages to be brief, factual and in Finnish, with Swedish where relevant.
General guidance, not legal advice. Check current rules with the regulator or a local adviser before launch.
Advertising Alongside Messaging
Advertising must be clearly identifiable, and the Consumer Ombudsman has issued guidance on influencer marketing.
