Documents Required and Instructions to Register Your Alphanumeric Sender ID in Cambodia

Before we begin

Effective August 1, 2023, all SMS messages sent from unregistered Alphanumeric Sender IDs to Smart Axiata Cambodia will be blocked. After this date, all SMS messages must be sent from registered Alphanumeric Sender IDs.

To prevent potential fraud or spam messaging, Smart Axiata Cambodia will only allow registered Alphanumeric Sender IDs to send SMS messages.

This article outlines the documentation requirements for a pre-registration in Cambodia.



To register your Alphanumeric Sender ID, the Cambodian network operators require that you provide the following documents:

  • Sender ID Registration for Cambodia (Excel file)
  • Customer to Twilio Appointment Letter (Only for Bank and Financial Institutions)

To get you up and running as quickly as possible, please fill out the document completely and accurately and provide any other required information. Use the examples provided for guidance. Note that mobile network carriers are very strict about the details!
