Formatting Portugal phone number lists correctly is crucial for successful WhatsApp broadcasting, ensuring messages reach recipients without being blocked or marked as spam. The process involves specific steps to comply with WhatsApp's requirements and technical necessities.
Firstly, ensure you have explicit, opt-in consent from every individual on your list to receive WhatsApp messages from your business. This is a legal requirement under GDPR and WhatsApp's policies. Without consent, broadcasting is prohibited.
Secondly, format the phone numbers accurately. Each number portugal phone number list must include the country code. For Portugal, this is +351. It must be a '+' followed immediately by '351'. Do not use spaces, dashes, or parentheses after the country code. The full format should be: (where X represents the 9-digit Portuguese mobile number). For example, a number might look like +351912345678.
Thirdly, the list itself should be clean and consistent. Use a simple, delimited format like CSV (Comma Separated Values) or TXT. Each line should ideally contain only the correctly formatted phone number, or the number paired with a unique identifier if needed for your broadcast platform. Avoid adding prefixes like 'whatsapp:' or 'tel:' in the list itself; your broadcasting software will handle the connection protocol.
Finally, ensure all numbers on the list are active WhatsApp accounts. While pre-verification tools can help, broadcasting to numbers not using WhatsApp is ineffective. Regularly clean your list by removing invalid or bounced numbers. Following these formatting guidelines helps maximize delivery rates and maintains compliance when sending broadcasts to Portugal via WhatsApp.
