Sender ID Rejected or Blocked in Morocco: What's Really Happening and How to Unlock It

In Morocco, the use of a personalized Sender ID (alfanumeric, e.g. ‘MA MARQUE’) is not automatic. It is subject to manual and asynchronous validation by the three operators (Maroc Telecom, Orange and inwi).

Here’s what really happens behind the scenes when your Sender ID is rejected, and how to structure your request to be validated at first.

In 90% of cases, a rejection by Moroccan operators is due to one of these 5 reasons:

1. Inconsistency with the Commercial Register (RC): You request the Sender ID EXPRESS_LIV but your company name on the RC is SOCIETE ALPHA LOGISTIQUE S.A.R.L. The operator requires proof of the legal link (a certificate of registration of a trademark at the OMPIC, for example).
2. Use of a generic term: Operators systematically reject Sender IDs that are not distinctive (e.g.: INFO, URGENT, PROMO, DIVISION).
3. Usurpation of institutional identity: Any application including the terms BANK, MINISTERE, POLICE, or names of major institutions will require a letter of authorization duly signed by the legal representative of the institution.
4. Invalid format: An alfanumeric Sender ID is limited to 11 characters, without special spaces or accents.
5. NOC: To activate a Sender ID, you must provide an official letter of commitment on header paper, signed and sealed, certifying that you are entitled to use that name.

Validation is not centralized.When you submit a request via your platform, we forward it to the three operators through our routing partners.

In practice, approval takes 15 to 30 days. It is common for a Sender ID to be validated by one operator several days before the other two. During this floating period, your shipments to the operator that has not yet validated the Sender ID will be blocked or crushed by a short number by default (depending on the gateway policy).

If your Sender ID was working and is suddenly blocked in full sending (state Rejected on specific numbers):

1. Check the content of your message. Sometimes it is not the Sender ID that is blocked, but the content of the SMS (suspicious phishing, spam) that has triggered a network filter.
2. Switch to an Emergency Sender ID. If you have a valid virtual number or digital Sender ID, temporarily change the sender setting in your API requests to not block your OTP or urgent notifications.
3. Contact technical support by providing the exact message_id in case of error. Support can escalate the incident, through its routing partners, to the operators' NOC (Network Operations Center) teams.

The difference between approval within the normal 15 to 30 days and a rejected file that has to be resubmitted is decided at submission.

Example of a poorly prepared folder (Assured Rejection): - Sender ID requested: Super Promo 2026 (too long, contains spaces, generic) - RC provided: On behalf of "Tech Solutions Sarl" - Letter of commitment: Absence or not signed.

Example of a perfect file (Approved without rejection): - Sender ID requested: TechSolutns (11 characters max, corresponding to the social reason) - RC provided: "Tech Solutions Sarl" (Lisible) - Letter of commitment: On header paper, signed by the manager, with the company stamp, stating explicitly: "We, Tech Solutions Sarl, authorize the configuration of the Sender ID 'TechSolutns' for our SMS sendings."

Always anticipate the creation of your Sender IDs at least 30 days before launching a new app or major campaign in Morocco.
