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

Before we begin

Due to regulatory requirements, there is sometimes a need for documents to be signed by customers to ensure that registrations are done on behalf of customers that have the right to use the Sender ID. This serves to ensure that traffic is coming from legitimate sources and minimizes any potential misuse.

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

Things to note

  • Separate registration process for Transactional and Promotional Senders.  Promotional Senders are only accepted for Domestic Entities.
  • Promotional Sender IDs must have an AD- prefix, which takes up 3 characters of the 11 character limit. 


To register your Alphanumeric Sender ID, the UAE network operators Etisalat and Du requires that you provide the following documents, which will be dependant on the origination of your Company and the traffic that you plan to send: 

  • Transactional UAE LOA (For all customers sending Transactional traffic)
  • Domestic Promotional UAE LOA (Only for Domestic customers sending Promotional traffic)
  • Domestic Promotional Sender Authorisation Form (Only for Domestic customers sending Promotional traffic)
  • Trade Licence (Only required for Domestic customers)

To get you up and running as quickly as possible, please fill out the documents 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! We highly recommend that you download the examples (hit right click, and select 'Save Image As...') and do a side by side comparison when you are filling out the documents.
