In alignment with previous efforts by Thailand's National Broadcasting and Telecommunications Commission (NBTC) to combat digital frauds, all SMS messages containing URLs must now have those URLs whitelisted. This regulation has been in effect since 1st Feb 2025, and applies to all SMS traffic types. It is also compulsory to register for a sender ID in Thailand.
#URL whitelisting requirements for SMS delivery to Thailand: 1. Sender ID 2. Company Name 3. Company URL/Website 4. Message Content with URL 5. Full URL 6. Company Registration Number
#Guidelines from the AMLO's (Anti-Money Laundering Office): 1. URLs must direct users to legitimate and verified destinations. 2. URLs must not lead to interactive platforms such as direct download sites or forms requiring user input. 3. The purpose of the URL must be transparent, lawful, and clearly communicated in the intent registration process. 4. URLs used in SMS campaigns may require prior approval from the National Cyber Security Agency (NCSA) - the process and approval time are to be confirmed in the official decree. 5. URLs that are generated by URL shorteners, such as Bitly, are not allowed as it is considered leading to a platform not belonging to the owner of the Sender Name.
Telesign has proactively submitted available URLs for registration with Thai operators to ensure optimal delivery rates and compliance. We will continue to monitor the evolving regulatory environment and provide updates as they become available.
