Using a list of Portuguese mobile numbers legally requires careful attention to regulations, primarily the General Data Protection Regulation (GDPR), which applies across the EU, including Portugal. A legal checklist is essential to ensure compliance and avoid significant penalties.
First, obtain valid consent. This is paramount. Verify that each individual on the list has explicitly agreed to receive communications from you, whether for marketing or other purposes. Consent must be freely given, specific, informed, and unambiguous. Keep clear records of how and when consent was obtained. For marketing calls, opt-in consent is generally required, not just an opt-out option.
Second, ensure the source is legitimate. If purchasing or acquiring a list from a portugal phone number list third party, confirm they also complied with GDPR, including obtaining consent. Using scraped or publicly available numbers without consent is illegal. Data must be obtained lawfully.
Third, provide an easy opt-out. Every communication sent via mobile must include a clear and simple way for recipients to unsubscribe or opt-out, typically a dedicated number to text or a link in the message. Honor these requests promptly.
Fourth, limit data processing. Only use the numbers for the specific purposes for which consent was given. Do not share or sell the list without additional consent.
Fifth, maintain data security. Protect the list from unauthorized access, loss, or breaches using appropriate technical and organizational measures.
Finally, be transparent. Clearly state who you are, why you are contacting the individual, and how their data will be used.
Adhering to this checklist helps ensure your use of Portuguese mobile numbers complies with GDPR and Portuguese law, protecting both your business and the individuals' privacy rights.
