Pro Tip: Save your number in your contacts as “My STC Number” the moment you find it. It is the detail most often needed when registering for a bank app, a delivery service, or a government platform like Absher.
Method 1: USSD Code *150# (Fastest)
- Open your phone’s dialler app
- Dial *150#
- Press the call button
- Your STC number appears on screen within seconds
This code is free, works on any phone including basic feature phones, and returns a result with zero balance on the account. It does not require mobile data or an internet connection. The dialler covers your balances too; the STC data balance check guide lists the codes for data and credit.
If the response appears in Arabic, press 2 to switch the display to English.
If you are on a dual-SIM phone, make sure you are dialling from the STC SIM slot specifically, since dialling from a different operator’s SIM will not return your STC number.
Method 2: Send a “Please Call Me” Message
If you have no balance and want someone nearby to read your number back to you, or simply want to share it without typing it out:
- Open your phone’s dialler app
- Dial *177* followed by the recipient’s mobile number, then #
- Press the call button
- The recipient receives a free SMS that includes your STC number
This is free and works with zero balance, though it is limited to a small number of free messages per day. Use it when you have someone nearby who can read your number back to you, or as a way to share your number without needing to remember or type it yourself.
Method 3: MySTC App
- Download the MySTC app from the Google Play Store or Apple App Store
- Open the app and log in with your mobile number, if you remember it, or your ID
- Your STC number appears on your account dashboard
If you do not remember your number at all, logging in through your Iqama or Absher-linked ID can still retrieve your account and display the number associated with it. The same dashboard shows your active plan; current bundle prices are in the STC monthly internet packages guide.
Method 4: Call Customer Support
Dial 900 from your STC SIM, free and available at any time. From another network or a landline, dial +966114555555. Ask the agent to confirm your STC number, and they can read it out or send it to you by SMS.
How to Check How Many STC SIMs Are Registered to You?
If you are not just trying to find one number, but want to know how many STC or Sawa SIM cards are currently registered under your identity, send the message 9988 to 902. This returns the total count of STC lines linked to your ID.
For a complete cross-network view showing every SIM card registered to your Iqama across all Saudi operators, not just STC, use the official CST Mutasil portal instead. For the full process, see the CST Argami SIM check guide.
What an STC Number Looks Like?
STC and Sawa mobile numbers in Saudi Arabia typically begin with one of a small set of prefixes, including 050, 053, and 055. If you see a number starting with one of these on your phone or in your contacts, it is likely an STC line, which can help you tell it apart from other operators on a dual-SIM device.
Troubleshooting: When *150# Does Not Respond
| Problem | Fix |
|---|---|
| No response after dialling | Check you have signal and retry in an open area |
| Code returns an error | Restart your phone, then retry the code |
| Response shown in Arabic | Press 2 to switch the display to English |
| Dual-SIM phone shows nothing | Confirm you dialled from the STC SIM slot, not the other SIM |
| Still not working | Call 900, or check the MySTC app |
