Philippines: SMS Guidelines
Dial Code: 63
Alphanumeric Sender IDs must be pre-registered. A Letter of Authorization (LOA) must be provided (Banking, Financial Institutions). In some instances, Alpha Sender IDs will be Overwritten by local operators to optimize delivery despite being registered.
The use of Generic Alpha Sender IDs (i.e. Verify, OTP, InfoSMS, etc) for transactional traffic is not allowed. Submissions with generic alpha Sender IDs will be rejected by local operators.
Due to high volumes of Spam and Phishing attempts, we highly advise for the use of Branded URLs instead of shortened URLs (i.e. bit.links).
Please make sure to always refer to our Acceptable Use Policy for Messaging.
