Documents Required and Instructions to Register Your Alphanumeric Sender ID in Saudi Arabia

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 Saudi Arabia.


To register your Alphanumeric Sender ID, the Saudi Arabian network operator Zain requires that you provide the following information : 

  • No Objection Certificate (NOC) 

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.

Once you have downloaded the forms, follow these general instructions: 

  1. Fill in the yellow highlighted fields—completely replace each field with your own information. If a field is not highlighted, don’t change it.
  2. If you have questions on how to fill in the required fields, refer to the annotated examples we provided for each field. 
  3. Have the documents signed by an authorized signatory of the Sender.
