STC SIM Number Check in Saudi Arabia (2026 Guide)

If you’ve recently purchased an STC SIM card or haven’t used your mobile number for a while, it’s easy to forget the number assigned to your SIM. Fortunately, Saudi Telecom Company (STC) offers several ways to find your mobile number without replacing your SIM card.

Whether you’re using a prepaid Sawa SIM or a postpaid connection, you can check your STC number using a USSD code, the mystc app, your phone settings, or customer support.

In this guide, we’ll explain every available method so you can quickly find your STC mobile number.

Quick Answer

You can check your STC SIM number by dialing the commonly used USSD code *150#, using the mystc app, checking your phone settings, calling another mobile phone, or contacting STC customer support. Keep in mind that USSD codes may change over time or differ depending on your plan, so if one method doesn’t work, try another.

What Is STC SIM Number Check?

STC SIM Number Check is the process of finding the mobile number assigned to your STC SIM card.

Many users need this service when they:

• Purchase a new STC SIM.
• Forget their own mobile number.
• Insert an old SIM after a long time.
• Need the number for banking or online verification.
• Register for government services.
• Share their number with family, friends, or employers.

Fortunately, there are several easy ways to retrieve your number.

Method 1: Check Your STC Number Using the USSD Code

The fastest method is dialing the commonly used STC number inquiry code.

Steps

1. Open your phone’s dialer.
2. Dial *150#.
3. Tap the Call button.
4. Wait a few seconds.

If the code is supported for your SIM and subscription, your mobile number should appear on the screen.

Note: STC does not currently publish an official “know my number” USSD code in its public documentation. Community guides commonly reference *150#, but availability may vary depending on your SIM type or future network updates. If it doesn’t work, use one of the alternative methods below.

Method 2: Check Your Number Using the mystc App

The mystc app is one of the easiest ways to manage your STC account.

Steps

1. Install or open the mystc app.
2. Sign in to your account.
3. Open the dashboard.
4. Your registered mobile number will usually appear with your active line details.

Besides viewing your number, the app also allows you to:

• Check your balance.
• Recharge your account.
• View your current package.
• Manage additional services.
• Review billing information.

Method 3: Check Your Number from Phone Settings

Many smartphones automatically display the SIM number.

Android

1. Open Settings.
2. Tap About Phone or SIM Manager.
3. Select your STC SIM.
4. Check whether the number is displayed.

iPhone

1. Open Settings.
2. Tap Phone.
3. Select My Number.

Depending on your device and SIM profile, the number may already be saved.

Method 4: Call or Send an SMS to Another Phone

If your SIM has active network service:

1. Insert the STC SIM into your phone.
2. Call or send a text message to another mobile phone.
3. Your number will appear on the recipient’s screen.

This is one of the quickest alternatives if the USSD code isn’t working.

Method 5: Contact STC Customer Support

If you still can’t find your mobile number, you can contact STC customer support for assistance.

The support representative may ask you to verify your identity before sharing your account information.

You may need:

• Your Iqama or National ID
• SIM card details (if available)
• Personal information associated with your account

Once your identity is verified, the representative can help confirm the mobile number linked to your SIM.

Method 6: Visit an STC Branch

If your SIM is inactive, blocked, damaged, or you’re unable to complete the online methods, visit the nearest STC branch.

Bring the following documents:

• Original Iqama or National ID
• The STC SIM card (if available)
• Passport (if requested)

After verifying your identity, an STC representative can help you identify the mobile number associated with your SIM.

Why Can’t I Find My STC Number?

Sometimes your number may not appear immediately. Here are the most common reasons.

The SIM Is New

A newly activated SIM may require some time before all account information is available across STC systems.

The SIM Is Inactive

If the SIM hasn’t been used for a long period, some services may not work until it is reactivated.

No Network Coverage

If your phone isn’t connected to the STC network, certain methods may fail.

Move to an area with better signal and try again.

Incorrect SIM Slot

If your phone supports Dual SIM, make sure you’re checking the correct STC SIM.

Phone Doesn’t Display SIM Information

Some Android devices and iPhones don’t automatically show the mobile number stored on the SIM card.

In this situation, use the mystc app or call another phone instead.

Tips for STC Users

To make it easier to remember your mobile number in the future:

• Save your number in your contacts.
• Register your account in the mystc app.
• Keep your Iqama and SIM registration details updated.
• Store your SIM packaging until activation is complete.
• Use only authorized STC stores for SIM replacement or ownership-related services.
