A step-by-step guide for Saudi Arabia
You can check the SIM cards linked to your Iqama using CST’s Arqami (My Numbers) service. This guide explains the web portal, checking without a registered mobile number, provider SMS options, the CST app, and National Access sign-in.
Why check?
Many people in Saudi Arabia hold several SIM cards for personal use, business, or internet access. If a SIM is registered in your name without your knowledge, it can cause problems. Arqami, the service from the regulator formerly known as CITC and now CST, helps you review registrations under your identity. Mobile companies such as STC, Mobily, Zain, Virgin, and Lebara can also help with checks on their own networks.
SIM limits per Iqama
SIM limits can depend on your customer category and the type of service. The commonly quoted figures of two prepaid and five postpaid voice SIMs should be confirmed with CST or your provider before relying on them. Do not assume that data SIMs are unlimited. Ask your operator about the current allowance for your Iqama.
Before you start
Never share an OTP with anyone. Use only your own identity and mobile details. Start from the official CST website and follow its service link, rather than entering your details into an unfamiliar website. Have your Iqama, date of birth if requested, registered mobile number if available, and access to the required verification method ready.
Method 1: Arqami web portal
Best if you have a mobile number registered on your Iqama.
- Open the official CST My Numbers service page and use the service entry point. Choose English or Arabic where available. Older guides may refer to arqami.citc.gov.sa; start from CST for the current route.
- Choose the individual inquiry category.
- Enter your Iqama number and any other details requested on the current form.
- Enter your registered mobile number if requested.
- Submit the inquiry and complete any verification shown, including an OTP or National Access sign-in if required.
- Review the phone numbers and data SIM registrations shown in your results.
Results note: CST says that the service shows active, authenticated numbers. If a number you expect is missing, contact the operator to check its authentication status.
| Step | Simplified example |
|---|---|
| Identity details | Iqama: 2XXXXXXXXX; date of birth only if requested |
| Mobile details | 05X XXX XXXX |
| Verification | Enter the code sent to your own phone |
| Results | 05X XXX 1234 — Mobily; 05X XXX 5678 — STC; data SIM — Zain |
These examples use made-up data and are simplified illustrations, not real screenshots or guaranteed current field labels.
Method 2: No registered mobile number
If the current inquiry form offers a no-number option, you can try the inquiry without entering a registered mobile number. The information available may be limited, and verification requirements can change.
- Open the official CST My Numbers service.
- Choose the individual inquiry category.
- Enter your Iqama number and any other required details.
- Select the option indicating that you do not have a registered mobile number, if offered.
- Submit the inquiry and review the available registration information. If the service requires National Access, follow its sign-in instructions.
A limited result may identify the companies holding registrations under your Iqama rather than reveal complete mobile numbers. If the no-number option is unavailable, ask CST or the relevant operator for help.
Method 3: SMS to your provider
An operator check covers its own network, so check each provider you may have used. The following STC, Mobily, and Zain codes were published in an official regulator notice. Since that notice is older, confirm continued availability with your provider if the request does not work.
| Provider | Send to | Message |
|---|---|---|
| Mobily | 616166 | Blank SMS |
| STC | 900 | 9988 |
| Zain | 700123 | Blank SMS |
| Virgin Mobile | Confirm with provider | Ask for the current SIM-registration inquiry method |
For Virgin Mobile, 1789 is listed as a customer-care contact. Do not assume that a blank SMS to this number performs a registration inquiry. Lebara customers should also confirm the current method with their operator.
Method 4: CST app
The CST app offers My Numbers services on Android and iOS. Use the official listing and check that the publisher is CST.
- Install and open the official CST app from Google Play or the App Store.
- Follow the app’s current sign-in flow.
- Complete National Access (Nafath) verification if requested.
- Open My Numbers / Arqami.
- Review the SIM registrations associated with your identity.
Screens, button names, and verification steps may differ between app versions. Never approve a sign-in request that you did not initiate.
Method 5: National Access (Nafath) sign-in
National Access is a sign-in route used by government services. It is not a separate SIM-registration database. Absher credentials may be involved in an approved National Access flow, but do not assume that Absher has a standalone CST SIM-list menu.
- Start from the official CST service or CST app.
- Choose National Access when the service offers it.
- Follow the official sign-in or Nafath approval instructions shown.
- Complete the verification for the request you initiated.
- Return to CST’s My Numbers service to view your available registrations.
Avoid opening an unfamiliar login page or entering your Absher password into a page claiming to provide an unofficial SIM lookup.
Found a SIM you do not recognize?
Contact the operator shown in the results, ask it to investigate the registration, and request cancellation if it is unauthorized. Keep the complaint reference. If it remains unresolved after five working days, use CST’s telecom complaint escalation service.
Review your registrations again after the operator completes the request. Requesting cancellation does not guarantee that it has already been processed.
Can I find an Iqama number from a mobile number?
There is no public reverse-lookup service in this guide for obtaining someone else’s Iqama number or identity from a mobile number. Operators protect subscriber information. Use official support channels to resolve issues with your own account.
