How to Register an Alphanumeric Sender ID in Morocco in 2026 (ANRT & Operator Guide)

Sending SMS messages with an alphanumeric Sender ID (e.g., YOURBRAND instead of an anonymous phone number) is the standard for certifying communication authenticity and building immediate trust with Moroccan recipients.

However, the Moroccan telecom market (regulated by the ANRT) enforces a mandatory declaration and approval procedure with the three national network operators: Maroc Telecom (IAM), Orange Maroc, and inwi. To combat phishing, brand impersonation (smishing), and spam, every custom Sender ID must undergo formal registration.

Without prior approval, messages dispatched with an unwhitelisted custom Sender ID will be blocked by operator SMS firewalls (returning HTTP 403 Forbidden or Rejected delivery status).

To submit your local Sender ID registration request to the ANRT and telecom operator desks, your application must provide the following 9 details:

Submitting your homologation application in the EnvoiSMS console takes less than 2 minutes. Follow these simple steps:

1. Navigate to Settings: Log in to your client dashboard at envoisms.ma/dashboard, click on Settings in the sidebar, and select the Sender IDs tab. 2. Open the Application Form: In the request form at the top, enter your desired Sender ID (3 to 11 GSM characters, without punctuation or special symbols). 3. Fill in Required Operational Details: - Company Website: Your official company or brand URL. - Message Type: Choose between Transactional, OTP / 2FA, or Marketing. - Sample Content: Enter the representative message template you intend to send. - Estimated Volume: Provide your projected monthly SMS volume. 4. Upload Official Legal Document: Click on the upload box and attach your PDF document (Commercial Register RC or OMPIC Trademark Certificate). 5. Track Review Status Live: Your submission will appear immediately in the lower table with real-time status updates (Pending, In Review, Approved, or Rejected with review notes). Once approved, it is immediately available in your campaigns and API requests.

The GSM 03.38 standard and operator SS7 gateways enforce strict rules on Sender ID formatting: - Length: Strictly 3 to 11 alphanumeric characters. - Allowed characters: Uppercase and lowercase letters (A-Z, a-z), digits (0-9), and single spaces. - Prohibited characters: Accents (é, è, à), special symbols (@, &, !, ?, #, %, *, _, -). - Composition: The Sender ID cannot consist purely of digits (to avoid confusion with shortcodes or phone numbers).

Registering a local Sender ID in Morocco requires regulatory compliance verification and technical provisioning on the SMS firewalls of all three national operators (IAM, Orange Maroc, inwi).

At EnvoiSMS.ma, Sender ID filing with the ANRT and Moroccan carriers is completely transparent:

• Setup & Filing Fee: 0 MAD (Free registration).
• Monthly Maintenance or Subscription: 0 MAD (No recurring commitments).
• Pricing Model: You only pay for successfully delivered SMS messages according to your pack rate (Pay-as-you-go).

Once your Sender ID is approved, using it in your software stack is immediate. Simply include your approved name in the sender parameter of your JSON payload.

To prevent application delays or carrier rejections:

• Generic non-distinctive names: Terms like INFO, URGENT, PROMO, or SERVICE are systematically rejected by Moroccan operators.
• Name mismatch: If your requested Sender ID differs from the company legal name on your RC, always supply the matching OMPIC trademark certificate.
• Document clarity: Always submit high-resolution, uncropped PDF documents.
