SMS Compliance in Portugal
A practical overview of the rules that affect SMS messaging and marketing in Portugal, with a checklist before you launch.
Key Rules for SMS in Portugal
In Portugal, marketing SMS and email to individuals require prior consent under Law 41/2004 on privacy in electronic communications and the GDPR, with an exception for similar products offered to existing customers. Each message must allow a free opt-out, and the CNPD supervises data protection.
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 CNPD enforces the GDPR and Law 58/2019, and websites need a clear privacy policy and consent before non-essential cookies.
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 +351 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Portugal follows the Europe/Lisbon time zone (UTC+01:00 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 Lisbon, customers commonly use Portuguese, 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 Portugal
Portugal is a WhatsApp-first market where customers often prefer to message businesses rather than call. SMS is widely used for appointment reminders, deliveries and bank codes, and alphanumeric sender IDs are supported.
MB WAY, a mobile payment app linked to Portuguese bank cards, is used by millions of people, and Multibanco references are a common way to pay online bills and orders. Business relationships are personal and courteous. The commercial calendar includes Black Friday, Christmas, the summer tourism season and Santos Populares festivals in June.
Portugal's economy relies on tourism, which has grown strongly, along with textiles, cork (Portugal produces about half of the world's cork), wine, automotive parts and a growing technology sector in Lisbon and Porto, helped by Web Summit and digital nomad visas. The standard VAT rate on the mainland is 23%, with lower rates in Madeira and the Azores. MB Way phone payments and Multibanco references are widely used. Law 41/2004 requires prior consent for marketing SMS and email to individuals.
