Philippines Letter of Authorization (LOA) guidelines

The registration of SMS senders in the Philippines is primarily aimed at curbing spam and fraudulent messages. It helps ensure that legitimate organizations and businesses can send SMS messages to consumers while minimizing unwanted and malicious content.

There are three networks in the Philippines that support local and international traffic:

• Smart Communications
• Globe Telecom
• DITO Telecommunity

Registration requirements

This section provides information about the requirements for registering your senders in the Philippines, which vary based on whether they are local or international senders.

Philippines registration has different requirements per network. Considering this, the Letter of Authorization (LOA) is a crucial document in the SMS sender registration process in the Philippines which helps verify the legitimacy of the sender, ensures compliance with regulations, and establishes accountability.

The Letter of Authorization documents are separated based on the following customer types:

• Direct customers - This customer type is usually the direct owner of the sender or brand.
• Wholesales/partners - This customer type is generally not the owner of the sender and brand but rather engages in reselling or re-purposing them, depending on their business model and use case.

Local senders registration

A local sender is an entity that operates within the Philippines and focuses on reaching recipients who are also located within the country. However, it is important to verify the location of the head office of the company that owns the sender. If the head office is situated outside the Philippines, telco will reject the sender, and it will be categorized as an international sender.

Various document requirements exist based on the company's type and the network in question. To expedite the registration of your sender, ensure that you complete and provide all necessary documents with precision and accuracy, along with any additional required information.

Before you complete the LOA, make sure to gather the following details, as they will be necessary when registering with telco, in addition to the LOA document.

• Company website/Facebook page
• Company (entity) name
• Content sample
• Traffic type (transactional/OTP/promotional, etc.)
• Estimated traffic volume per month
• General Information Sheet (GIS)

Smart Communications

The sender's company should have headquarters located in the Philippines and have all necessary documents that it is registered in the Philippines. Additionally, the company and brand should not operate outside the Philippines as based on the international guidelines (see above).

For traffic requirements, the following should be noted:

• A2P SMS that is used for One-Time Passwords (OTPs) should have the company name as part of the body of the message. This is to reduce instances of fraud and to be able to identify the company that intended to send the SMS.
• Templates with URL shorteners will be blocked for all Sender IDs. In order to avoid blocking, it is recommended to follow the format which uses full URLs in messages so that the destination site is clearly visible to the recipient.
