You have an MTN SIM card and you are unsure if your number is properly registered with ONECI. This concern affects many subscribers in Côte d’Ivoire, especially since operators have tightened identification controls. An unregistered number risks being suspended outright. Knowing how to check your status in a few minutes from your phone can help avoid unpleasant surprises.
MTN USSD Code: Verification Without Internet Connection
Before discussing online platforms, it’s important to know the quickest method. On your MTN phone, dial a short USSD code directly from the call keypad. No need for a smartphone or data plan.

The principle is simple: you enter the code, validate the call, and a message appears within seconds. This message indicates whether your number is identified, partially identified, or unregistered. If the status shows “identified,” your line is in order.
This method works even in areas with weak internet coverage. This is a crucial point: users in rural areas often face persistent difficulties with online verification, making the USSD code even more useful. To learn more about how to verify your MTN identification online, the ONECI platform remains the official reference.

ONECI Platform: Verify Your MTN Identification Online Step by Step
ONECI (National Office of Civil Status and Identification) manages the central database for mobile subscriber identification in Côte d’Ivoire. All operators, including MTN, rely on this system.
Access the portal identification-abonnes.oneci.ci
Visit the official ONECI website dedicated to identification. The homepage offers two options: pre-identification (for those who do not yet have a SIM card) and identification (for those who already have an active SIM).
Select “Identification – I have a SIM card.” The form unfolds in four steps.
The Four Steps of the ONECI Form
- Step 1 – Number to Identify: enter your MTN number in the format +225 followed by the ten digits, then select MTN as your phone operator.
- Step 2 – Personal Information: provide your gender, last name, first names, and date of birth as they appear on your official identification document.
- Step 3 – Supporting Document and Photo: upload a copy of your national ID, passport, or consular card, along with a recent passport photo.
- Step 4 – Summary and Validation: review all the information, then confirm. A confirmation SMS will be sent to the declared number.
The point that often blocks subscribers is the quality of the scanned document. A blurry photo or a cropped scan leads to automatic rejection. Take the photo in a well-lit place, against a light background, with the document laid flat.
ONECI ID Mobile Application
Since the deployment of the ONECI ID mobile application in March 2025, most verifications are done directly from a smartphone. The application follows the same steps as the website, with the added advantage of using the phone’s camera to capture the identification document and photo in real-time.
This deployment has resulted in a significant decrease in queues at MTN agencies. According to operator feedback, about 70% of verifications now occur digitally.
MTN Identification and Personal Data Protection
Mobile identification involves the collection of biometric data: facial photo, fingerprint associated with the national ID, civil information. You are entrusting sensitive data to ONECI.
ARTCI (Regulatory Authority for Telecommunications of Côte d’Ivoire) oversees the storage and use of this data by operators. Subscribers have the right to access and rectify their personal information with ONECI.
Have you noticed that the form requests an email in addition to the phone number? This email serves as a notification channel in case of changes to your file. Provide an address that you check regularly, not an email created for the occasion.
The question of the right to be forgotten also arises. If you cancel your MTN line, your biometric data remains in the ONECI database. No simplified deletion procedure currently exists, which is a concern for subscribers worried about their privacy.
What to Do If Your MTN Number Appears as Unregistered
An “unregistered” status does not mean your line will be cut off within the hour. You usually have a grace period to regularize the situation. After this period, outgoing calls are blocked, and then the line is suspended.
Three options to regularize:
- Resume the online procedure on the ONECI portal or via the ONECI ID app, ensuring that the uploaded document is legible and that the information exactly matches the identification document.
- Visit an MTN agency with the original identification document. The agent will perform the identification on-site, and confirmation will arrive via SMS.
- Take advantage of the mobile identification caravans launched by MTN in about fifteen regions since October 2025, targeting rural areas where internet coverage remains insufficient for online verification.
If after regularization the status does not change within a few days, contact MTN customer service or visit an agency with your identification receipt.
Identifying your MTN number in Côte d’Ivoire can be done quickly via the USSD code for a quick check, or through the ONECI portal and its application for a complete process. Urban subscribers no longer have a reason to go to an agency.
Those in rural areas can rely on the MTN caravans deployed to compensate for the limitations of the internet network. Keep your identification document up to date and have an active email: these are the two elements that prevent most blocks.
