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. 
  • The UAE promotional content allowed window time is (7 AM to 9 PM UAE time).
  • The end client's Company Name and Sender ID have to be relevant to each other. In case the company name is different from the sender ID, but the sender ID is a brand of that company, then the client should provide trademark certificate or brand name mentioned on the trade license, which proves that the sender ID is a brand of that company. Or any document issue from UAE authorized regulatory to prove the company and brand relation.
  • In the case of the Medical Sender ID - MOH is mandatory. MOH licensing is an official permit given to healthcare professionals to keep a medical practice in UAE. In order to get the license, they need to get through the exam conducted by the Ministry of Health and Prevention in UAE.
    If the company does not have MOH, DOH licensing is required to be submitted.
