Messaging Compliance in Portugal
SMS, WhatsApp, voice and RCS rules for businesses messaging customers in Portugal.
Overview
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.
The CNPD enforces the GDPR and Law 58/2019, and websites need a clear privacy policy and consent before non-essential cookies.
European Portuguese is the search language; spelling and vocabulary differ from Brazilian Portuguese, so copy should be adapted for Portugal rather than reused.
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.
European countries regulate marketing calls through national laws and do-not-call or objection registers, and automated (recorded) marketing calls generally require prior consent.
Advertising Rules
Advertising must follow the Código da Publicidade and the Auto Regulação Publicitária (ARP) code, and sponsored influencer content must be clearly identified.

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.
