UAE & Saudi Arabia

Short answer

To send A2P SMS under your brand name in the UAE or Saudi Arabia, you register an alphanumeric sender ID through a licensed provider, which submits it to the operators under rules set by TDRA in the UAE and CST in Saudi Arabia. You declare whether the ID is promotional or transactional, provide company and authorization documents, and wait for approval. Rules, formats and timelines change, so confirm current requirements with the regulator and your provider.

Key takeaways

  • A sender ID is the name or number that appears as the SMS sender; in the GCC, alphanumeric sender IDs generally must be registered before use.
  • Promotional and transactional traffic are usually registered separately and treated differently for content, timing and opt-out.
  • Registration typically needs a trade license or commercial registration, an authorization letter and proof that you own or may use the brand name.
  • Providers commonly report promotional formats such as an AD- prefix in the UAE and a -AD suffix in Saudi Arabia; confirm current formats before submitting.
  • Timelines vary from days to several weeks depending on operator, documents and season, so register well before launch.

This guide is for marketing, compliance and product teams preparing to send business SMS in the UAE or Saudi Arabia. It explains what a sender ID is, how promotional and transactional registration differ, which documents are usually requested and how to avoid the delays that hold up launches. It is a practical overview, not legal advice: rules change, so confirm every detail with the regulator and your licensed provider.

What is an SMS sender ID?

A sender ID is the identity that appears in the From field of a text message. Business SMS, often called A2P (application-to-person) SMS, usually uses one of three types:

Sender type What the recipient sees Typical use Two-way replies
Alphanumeric sender ID A brand name, up to 11 characters OTPs, alerts, marketing No
Long code A standard phone number Conversational or low-volume messaging, where permitted Yes
Short code A short number High-volume campaigns and keyword opt-ins, where available Yes

In the UAE and Saudi Arabia, alphanumeric sender IDs are the norm for business SMS and generally must be registered before operators deliver traffic. Unregistered IDs may be blocked, replaced with a generic sender or delivered unreliably.

Who regulates business SMS in the UAE and Saudi Arabia?

In the UAE, the Telecommunications and Digital Government Regulatory Authority (TDRA) sets the framework and the licensed operators apply it. In Saudi Arabia, the Communications, Space and Technology Commission (CST), formerly CITC, regulates the sector, and operators and licensed aggregators apply its rules.

In practice, businesses rarely deal with the regulator directly. You register through a licensed SMS provider or aggregator, which submits your sender ID to the operators and is responsible for passing on the current requirements. Check the TDRA and CST websites for official guidance, consumer-protection rules and any updates.

What is the difference between promotional and transactional sender IDs?

Promotional and transactional traffic are registered and handled separately. The category you register determines what you may send, when and to whom.

Aspect Transactional Promotional
Purpose OTPs, payment and order confirmations, appointment reminders, service alerts Offers, product launches, events, re-engagement
Consent Based on the existing customer relationship Explicit opt-in generally expected, with working opt-out
Sending hours Generally any time Restricted to daytime windows that providers report differently by country; confirm current hours
Sender format Brand name Providers commonly report an "AD-" prefix in the UAE and a "-AD" suffix in Saudi Arabia
Content Strictly informational Marketing allowed, subject to content rules (for example on religious, political or gambling content)
Do-not-disturb lists Generally not applied Applied by operators where they exist

Promotional formats, character limits and quiet hours are the details that change most often and that vendor guides disagree on. Treat the table as orientation and get the current rule in writing from your provider before you register.

What documents are typically required?

Exact lists vary by operator, provider and whether you are a local or foreign entity, but most applications ask for some combination of:

  1. Trade license (UAE) or commercial registration (Saudi Arabia) showing the legal entity and activity.
  2. Authorization or letter of authority on company letterhead, signed and stamped, naming the sender IDs requested and the provider permitted to send on your behalf.
  3. Proof of right to use the name when the sender ID differs from the legal entity name, such as a trademark certificate, franchise agreement or brand ownership letter.
  4. Sample messages for each sender ID showing the intended content and traffic type.
  5. Contact details of an authorized signatory.
  6. For agencies or resellers, an authorization from the brand owner for each client sender ID.
  7. For promotional traffic, evidence of how consent is collected and how opt-out works, if requested.

Sender names usually have to relate clearly to your company or brand. Generic words, other companies' brands and misleading names are typically refused.

How long does registration take?

There is no single published timeline that applies to every case. Approval depends on how many operators must approve the ID, how complete and consistent your documents are, whether the name matches your entity or trademark, and seasonal load before events such as Ramadan, White Friday or national days. Providers report anything from a few business days to several weeks, and renewals can also be required periodically.

The safe assumption: begin registration as soon as you know the brand name and traffic type, and treat sender ID approval as a launch dependency on your project plan.

Step-by-step: registering a sender ID

  1. Decide the traffic types. List every message you will send and classify each as transactional or promotional.
  2. Choose the names. Keep them short, recognizable and tied to your legal or trademark name; check formatting rules for promotional IDs.
  3. Gather documents from the list above, making sure names, entity details and signatures match exactly.
  4. Write sample messages per sender ID and language, including Arabic versions if you will send them.
  5. Submit through your licensed provider and ask which operators the ID will be registered with.
  6. Track approval per operator; an ID can be live on one network before another.
  7. Test delivery to numbers on every operator before launch.
  8. Document consent and opt-out handling for promotional traffic and keep records.
  9. Calendar renewals and changes in company details that require re-registration.

Worked example: a UAE e-commerce brand expanding to Saudi Arabia

"Sahra Home" (synthetic), a Dubai-based furniture retailer, plans to launch in Riyadh. It needs OTPs at checkout, delivery updates and a launch promotion.

  • UAE: it already has a transactional ID, SAHRAHOME, and registers a separate promotional ID in the format its provider confirms for current UAE rules.
  • Saudi Arabia: the Saudi entity is still being set up, so the provider explains which documents a foreign company can use and which require local registration. Sahra Home submits a transactional ID first, because checkout OTPs are critical, and the promotional ID once the commercial registration is issued.
  • Planning: the team allows several weeks for Saudi approval, schedules the launch campaign only after test messages arrive on each operator, and sends promotions within the permitted hours confirmed by the provider.

Common mistakes and limits

  • Launching before approval. Unregistered or pending IDs can be blocked or replaced.
  • Mixing promotional content into OTPs or alerts. This risks suspension of the transactional ID.
  • Mismatched documents. A trade license name that does not match the letter of authority is a common cause of rejection.
  • Relying on outdated blog posts, including this one, for formats, hours or fees. Confirm with TDRA, CST and your provider.
  • Forgetting Unicode costs. Arabic SMS segments hold fewer characters, so long messages cost more.
  • No consent records for promotional lists.

Frequently asked questions

What is an SMS sender ID?

A sender ID is the identity shown in the From field of an SMS. It can be an alphanumeric name, such as a short brand name of up to 11 characters, or a numeric long code or short code. In the UAE and Saudi Arabia, alphanumeric sender IDs used for business messaging generally must be registered through a licensed provider before traffic is delivered.

What is the difference between promotional and transactional SMS?

Transactional SMS carries information a customer needs about an existing relationship, such as OTPs, payment confirmations, appointment reminders or delivery updates. Promotional SMS markets products, offers or events. Regulators and operators treat them differently: promotional traffic usually needs explicit consent, opt-out, a specific sender format and restricted sending hours, while transactional traffic usually can be sent at any time.

Can I use the same sender ID for OTP and marketing?

Usually not. Most providers ask you to register separate promotional and transactional sender IDs, and mixing promotional content into transactional traffic can lead to blocking or suspension. Keep OTPs and service alerts on a transactional ID and send marketing only from a registered promotional ID to opted-in recipients.

How long does sender ID registration take in the UAE or Saudi Arabia?

There is no single fixed timeline. Approval depends on the operators, the completeness of your documents, whether the name matches your legal entity or trademark, and seasonal volume. Providers report anything from a few business days to several weeks. Start early, submit complete documents and ask your provider for current expectations.

Do international companies need a local entity?

Requirements differ by country and change over time. Some routes accept foreign companies with additional documents, such as a trademark certificate or authorization from a local entity, while others expect a local trade license or commercial registration. Ask your licensed provider which documents apply to your company and traffic type before you start.
