You can’t send a single legitimate promotional SMS in Dubai without one. A sender ID is what makes your brand name appear on the recipient’s phone instead of a random number. It’s the difference between a message that reads “YourBrand” at the top and one that reads “+971509876543.”
In the UAE, sender ID registration is mandatory. TDRA requires every business to register alphanumeric sender IDs with both Etisalat (e&) and du before any promotional traffic goes live. Not after. Not as a formality. Before. And yet this is the step we see Dubai businesses skip, delay, or fumble more than almost any other part of launching an SMS campaign.
The reasons are predictable. The process involves two separate operators, specific document formats, a portal that takes some getting used to, and approval timelines that don’t move faster no matter how urgent your campaign feels. Plan this wrong and your launch date slips by two weeks.
This guide walks through the full registration process. Every document. Both portals. The fees. The most common rejection reasons. And the industry-specific requirements that apply to healthcare, real estate, and financial services businesses in the UAE.
Quick answer for the impatient: Sender ID registration in Dubai takes 5 to 10 working days for local UAE-registered companies, and 10 to 15 working days for international companies. There is no expedited option. The only way to get your sender ID live faster is to submit complete, accurate documentation the first time. Most delays come from fixable errors in the paperwork, not from the operators being slow.
What Is a Sender ID and Why Does It Require Registration in Dubai?
A sender ID is the alphanumeric name displayed as the sender on an SMS. When a recipient opens a text from “AD-DigitizeBird” or “ShopXpress”, that’s the sender ID at work. It replaces the numeric mobile number a message would otherwise show.
In many countries, businesses can use sender IDs without pre-registration. The UAE is not one of those countries. TDRA mandates that all alphanumeric sender IDs used for commercial purposes be registered with UAE operators before any traffic is sent. This applies to both promotional and transactional SMS.
The logic behind this is consumer protection. Every registered sender ID is tied to a verified business entity with a valid UAE trade license. Recipients can trust that a message from “AD-BrandName” comes from a real, registered company. Unregistered sender IDs get blocked at the network level. The operator infrastructure filters them out before they reach the handset.
Promotional sender IDs must carry the “AD-” prefix, for example AD-YourBrand. The entire string including the prefix must be 11 characters or fewer. These IDs are only approved for businesses with a local UAE trade license.
Transactional sender IDs carry no mandatory prefix. They can be up to 11 characters. These are approved for operational messages: OTPs, booking confirmations, delivery alerts. They cannot be used for marketing content under any circumstances.
| Critical rule: The same sender ID cannot be registered for both promotional and transactional traffic. You need separate sender IDs for separate message types. Using a transactional sender ID to send a promotional offer is a TDRA violation that results in blocking, not just a warning. |
Before You Start: The Documents You Need
Gather these before you open either portal. Operators are strict about documentation. A missing stamp, a different authorised signatory than the one on the trade license, or a sample SMS that reads too promotional when you’re registering a transactional ID can send your application back to the start.
| Document | Required For | Notes |
| Valid UAE Trade License | All applicants (local companies) | Must have at least one month of validity remaining. Scanned copy, clearly legible. |
| NOC on company letterhead | Both Etisalat and du (separate forms) | Must be signed and stamped by the authorised signatory named in the trade license. |
| du Form B (Enterprise SMS Portal form) | du registration only | Download from du portal. Fill digitally or print, sign, and stamp. Date must be current. |
| Etisalat CMS Portal application | Etisalat registration only | Separate portal. Requires Party ID and Blockchain ID after initial approval. |
| Emirates ID / Passport of authorised signatory | Both operators | The person who signs the NOC must match the trade license. National ID, passport, or driving licence accepted. |
| Power of Attorney (if signatory differs from trade license owner) | Both operators | Must reference Etisalat or du specifically. Must be notarised by a UAE court. This catches many applicants off guard. |
| Sample SMS messages | Both operators | Typically 2 to 3 examples of the messages you plan to send. They must match your declared message type: promotional or transactional. |
| Trademark Certificate or VAT Certificate (if sender ID name differs from company name) | Both operators, as applicable | Required when the brand name you want as sender ID does not clearly match your registered company name. |
Two industry-specific additions are worth flagging separately. Healthcare businesses require a Ministry of Health approval copy for any health-related sender ID. Real estate businesses in Dubai require a RERA registration certificate. These approvals can add 5 to 10 additional working days before your sender ID registration can proceed.
The Registration Process: Step by Step
Registration runs through two separate workflows: one for Etisalat and one for du. Both operators must approve your sender ID. The process starts with Etisalat because they issue a Blockchain ID that you then need for the du submission.
Phase 1: Etisalat (e&) Registration
- Open a CMS Account with Etisalat Visit the Etisalat Consent Management Service (CMS) portal. You’ll need your trade license to register as an entity. Etisalat assigns you a Party ID upon account activation. This Party ID is referenced in subsequent documents, so note it carefully.
- Submit Your Sender ID for Approval
Log in to the CMS portal and submit your proposed sender ID along with your business category and message type (promotional or transactional). Upload your supporting documents: trade license, NOC on letterhead, authorised person’s ID, and sample SMS messages. Etisalat reviews the submission against TDRA guidelines. - Receive Your Blockchain ID Once Etisalat approves your sender ID, they email you a Blockchain ID. This is a unique identifier tied to your registered brand name. Guard this carefully. You’ll need it for the du submission. Without a Blockchain ID from Etisalat, du cannot process your sender ID registration.
Phase 2: du (EITC) Registration
- Open an Enterprise SMS Portal (ESP) Account with du Download and complete du’s Form B (Enterprise SMS Portal registration form). Fill in your company details, the authorised person’s information, and the Etisalat Blockchain ID you received in the previous step. The form must be signed, stamped, and dated.
- Submit Documents to du Submit Form B, your NOC letter on company letterhead, the authorised person’s ID, your trade license, and any additional documents relevant to your industry. du reviews your application against their own criteria, cross-referencing the Blockchain ID from Etisalat to confirm consistency.
- Receive ESP Entity ID from du Once du approves the account, they issue an ESP Entity ID. Your sender ID is now registered across both UAE networks. Share both the Blockchain ID and the Entity ID with your SMS platform provider so they can complete the whitelisting process on their end.
- Whitelisting Through Your SMS Provider
Your platform provider uses the Blockchain ID and Entity ID to whitelist your sender ID on their gateway. This connects your registered sender ID to your account so messages go out correctly. This final step typically takes 1 to 2 working days once you provide the IDs.
| One sender ID, both networks: A sender ID registered with Etisalat (e&) is not automatically active on du, and vice versa. Both registrations are required to reach all UAE mobile users. Etisalat holds approximately 54% of UAE mobile market share and du around 46%. Registering with only one operator means your messages won’t deliver to roughly half your list. |
Timelines: What to Realistically Expect
| Company Type | Typical Approval Time | Notes |
| UAE-registered local company (promotional) | 5 to 10 working days | Faster when documents are complete and match exactly on first submission. |
| UAE-registered local company (transactional) | 5 to 10 working days | Same timeline. Healthcare and real estate add 5 to 10 more days for sector approvals. |
| International company (transactional only) | 10 to 15 working days | International companies cannot register promotional sender IDs in UAE. Transactional only. |
| Re-registration after lapse (inactive 6+ months) | Full process restart | TDRA deactivates sender IDs inactive for 6 months. Full registration required again. |
| Sender ID with name differing from company name | Add 3 to 7 working days | Requires trademark or VAT certificate. Operators take more time to verify brand ownership. |
Plan these timelines into your campaign calendar. If your first bulk SMS campaign in Dubai is tied to a specific date, such as a product launch or a seasonal promotion, submit your registration at least three weeks before that date. Two weeks of buffer on a 10-day approval window is the minimum comfortable margin.
The Fees Involved
Sender ID registration in Dubai carries two charges: a one-time setup fee and a recurring monthly renewal.
| Fee | Amount (AED) | Notes |
| One-time registration fee | AED 500 | Paid at initial registration through Etisalat’s system. Covers both operators as part of the unified registration process. |
| Monthly renewal | AED 100 per sender ID | Payable every month. Non-payment leads to deactivation. Six months of non-payment means full re-registration. |
| Inactivity reactivation | Full re-registration cost | No reduced fee for reactivation. Same AED 500 setup and full document resubmission. |
The monthly AED 100 is genuinely non-optional. We’ve seen Dubai businesses register a sender ID for a major campaign, then ignore the monthly renewal after the campaign concludes. When they try to send again six months later, the sender ID has lapsed and they’re back to square one, with a three-week delay before their next campaign can go live.
If you run seasonal campaigns, build the monthly renewal into your overhead regardless of whether you’re actively sending. AED 1,200 per year to keep an asset active is a reasonable cost of maintaining campaign readiness.
Common Rejection Reasons and How to Avoid Them
Most rejections are preventable. Operators don’t reject applications arbitrarily. They return them when the documentation doesn’t meet the exact requirements. These are the issues we see most frequently:
- Signatory mismatch: The person who signed the NOC is not the authorised signatory on the trade license. If someone other than the business owner signs, you need a notarised Power of Attorney that specifically references Etisalat or du. This is the single most common rejection reason for Dubai companies.
- Sender ID name doesn’t match company name: You want to register “AD-MyShop” but your trade license says “My Shopping LLC.” That’s a mismatch. You need a trademark certificate or VAT certificate showing the relationship between the brand name and the registered entity.
- Sample SMS looks promotional on a transactional application: If your sample messages contain offer language, discount percentages, or calls to action, the operator will classify them as promotional. Transactional applications need samples that read as operational: order confirmations, appointment reminders, delivery alerts.
- Handwritten documents: Operators don’t accept handwritten NOC letters or forms. Everything must be typed. Handwritten signatures and company stamps are fine. The body of the letter must be typed on letterhead.
- Trade license validity: A trade license with under one month of validity won’t be accepted. If your license renews soon, renew it first, then register.
- URLs in sample messages not whitelisted: If your sample SMS includes a link, that URL must be pre-whitelisted with the operators. Common short URL services like bit.ly are universally blocked on UAE networks. Use your actual domain.
Industry-Specific Requirements in Dubai
Healthcare (DHA-Regulated Businesses)
Clinics, hospitals, pharmacies, and health professionals in Dubai require a Ministry of Health and Prevention (MOHAP) approval copy alongside the standard documents. The approval letter must specifically permit the use of SMS for patient communication. Dubai Health Authority (DHA) regulated businesses follow the same requirement under DHA oversight.
The health sector sender ID check is more thorough because TDRA applies stricter content standards to health-related messages. Sample SMS submissions for healthcare applications must be clearly non-promotional: appointment reminders, test result notifications, prescription alerts. Any message that could be construed as advertising a health service triggers additional scrutiny.
Real Estate (RERA-Regulated Businesses)
Dubai real estate agents, developers, and property management companies must submit their RERA registration certificate alongside standard documents. The RERA cert confirms the business is a licensed real estate entity in the emirate. Without it, operators won’t register a sender ID for property-related SMS traffic.
This applies whether the sender ID is for promotional property listings or transactional messages like payment reminders to existing clients. The RERA certificate is a hard requirement for both categories.
Financial Services
Financial services businesses in Dubai face the additional context of the Central Bank’s 2026 directive phasing out SMS-based OTPs for banking authentication by March 31, 2026. This affects authentication sender IDs specifically. Transactional sender IDs for payment alerts, account updates, and non-OTP financial notifications are unaffected and follow the standard registration process.
DIFC and ADGM-regulated entities register sender IDs through the same Etisalat and du process. Their sector-specific compliance frameworks don’t change the operator registration requirements.
Frequently Asked Questions About Sender ID Registration in Dubai
Can I use a numeric sender ID for SMS in Dubai?
No. Numeric-only sender IDs are not supported for business SMS in the UAE. All commercial sender IDs must be alphanumeric: your brand name or a name clearly connected to your registered company. Numeric IDs are filtered by UAE operators before they reach recipients.
Do I need to register with both Etisalat and du separately?
Yes, both registrations are required. However, the process is sequential rather than parallel. You register with Etisalat first, receive your Blockchain ID, and then use that ID as part of your du application. Your SMS provider typically handles the coordination between both operators once you supply the documentation.
Can an international company register a promotional sender ID in Dubai?
No. Promotional sender ID registration in the UAE is only available to companies with a local UAE trade license. International companies without UAE registration can register transactional sender IDs, which cover OTPs, alerts, and operational notifications. If your business operates in Dubai but is incorporated elsewhere, you’ll need a UAE trade license before you can run promotional SMS campaigns legally.
What happens if I send SMS with an unregistered sender ID?
Messages with unregistered sender IDs are filtered and blocked by Etisalat and du at the network level. They don’t deliver. Beyond non-delivery, sending unregistered promotional traffic is a TDRA violation. Fines start at AED 10,000 and reach AED 150,000 per violation under Cabinet Decision No. 57/2024. Repeated violations can result in business license suspension.
