How to Check Your Zain SIM Card Number in Saudi Arabia 2026

Why You Might Need Your Zain SIM Number

It is surprisingly easy to lose track of your own mobile number, especially when you have multiple SIMs or have just inserted a new Zain card. According to a 2025 regional telecom survey, over 31% of mobile users in Saudi Arabia forget their numbers at least once a year. Here are the most common situations where you will need to know your Zain number:

Government e-services registration: Saudi platforms, including Absher, Tawakkalna, and Muqeem, require a verified mobile number linked to your Iqama or national ID. If your number has changed or you are setting up a new SIM, you will need to confirm the exact number before completing registration.

Recharging your SIM: Many recharge portals, including SADAD, bank apps, and voucher-based top-ups, require you to enter your exact Zain mobile number to process the transaction.

WhatsApp and app verification: When setting up WhatsApp or any app that uses SMS OTP verification, you need your current phone number. If you recently swapped SIM cards, this is the first thing to confirm.

Contacting Zain customer service: When you call 959, the customer service system may ask you to confirm your number for account identification before connecting you to an agent.

SIM registration compliance: Saudi Arabia’s CST (formerly CITC) mandates that all SIM cards be registered under a valid ID. Knowing which number is currently active under your Iqama helps ensure compliance and supports number portability if you decide to switch operators.

Multiple SIM management: If you use separate SIMs for personal use, data, and business, identifying which number belongs to which card is essential for managing packages, top-ups, and call forwarding correctly.

Setting up a new phone or dual SIM device: When moving your Zain SIM to a new device, you may need to confirm the number during setup, especially for eSIM profiles that require your existing number for authentication.

Method 1: Dial *144# (Fastest and Most Reliable)

This is the primary and most widely used method. It works on any phone, requires no internet, and displays your number in under five seconds.

Steps:

1. Open your phone’s dialer (the app you use to make calls)
2. Type *144# exactly, including the asterisk (*) at the start and the hash (#) at the end
3. Press the call button
4. A pop-up message appears on your screen showing your Zain SIM number
5. Note down or screenshot the number before dismissing the pop-up

Works on: All phones, including basic keypad mobiles, Android, iPhone, and dual-SIM devices.

Balance required: No. This USSD code works even when your balance is zero.

Tip for dual-SIM phones: If you have two SIMs in your phone, make sure the Zain SIM is selected as the line used for the dial when using *144#. On most Android devices, a prompt will ask which SIM to use before connecting.

Method 2: Alternative USSD Code *23#

If *144# does not work for any reason, use *23# as a backup:

1. Open your phone’s dialer
2. Dial *23# and press the call button
3. Your Zain number appears in a pop-up on the screen

This is functionally identical to *144# and retrieves the same information. A third backup code, *34#, has also been reported to work by some users, though it is less commonly used.

Method 3: Send a Blank SMS to 700123

This method is useful if USSD codes are not working on your device or if you prefer a text-based response.

Steps:

1. Open your phone’s messaging app
2. Create a new message addressed to 700123
3. Leave the message body completely empty (do not type anything)
4. Send the message
5. You will receive an automatic reply from Zain containing your SIM number

Important note: The reply from 700123 shows all Zain numbers registered under your Iqama or national ID, not just the SIM currently in the device. If you have two Zain lines registered under your name, both numbers will appear in the reply. This is useful for verifying all active lines linked to your identity.

Balance required: No. SMS to short codes like 700123 do not consume regular SMS credit on Zain.

Method 4: Check via the Zain KSA App

The Zain App is the most comprehensive self-service option for account management, and it displays your SIM number in the account profile section.

Steps for Android:

1. Open the Google Play Store and search for “Zain KSA.”
2. Install the official Zain KSA app (published by Zain Saudi Arabia)
3. Open the app and log in using your Zain account credentials
4. If you do not have an account, tap “Register” and complete setup using your Zain number and Iqama
5. Once logged in, go to Profile or Account Info
6. Your Zain SIM number is displayed on the account overview screen

Steps for iPhone:

1. Open the App Store and search for “Zain KSA.”
2. Download and install the app
3. Log in or register as above
4. Navigate to Profile to view your number

Additional features in the Zain App: Balance check, data usage, package activation and cancellation, recharge, bill payments, and Zain Black account management. The app also supports Face ID and fingerprint login for faster access.

Useful when traveling outside Saudi Arabia: When you are abroad, and USSD codes may not connect to the Zain KSA network, the Zain App provides reliable access to your number and account details over Wi-Fi or data from any country.

Method 5: Check in Phone Settings (Android and iPhone)

Your SIM number may be stored in your phone’s system settings without needing to contact Zain at all.

On Android:

1. Open Settings
2. Tap About Phone or About Device
3. Tap SIM card information or SIM status
4. Your phone number is listed under “SIM phone number” or “My phone number.”

If the field shows “Unknown” or is blank, your SIM number has not been stored in the device, and you will need to use one of the other methods.

On iPhone (iOS):

1. Open Settings
2. Tap General
3. Tap About
4. Scroll down to find “Phone Number” listed under the SIM details

On newer iPhones with dual physical and eSIM support, both numbers are listed separately. Confirm which one corresponds to your Zain SIM based on the carrier name shown.

Method 6: Call Someone or Send a Message

A quick and simple approach when other methods are not available:

Call a contact: Call a friend, family member, or colleague. Your number appears on their screen as the incoming call. Ask them to read it back to you.

WhatsApp or messaging apps: If your Zain SIM is linked to WhatsApp, you can check your own WhatsApp profile to see the number associated with your account.

Use the “Call Me Back” feature: In areas with poor signal, you can request a callback from a contact. When they call you back, the call display confirms your own number.

Method 7: Check the Original SIM Card Packaging

When you first purchased your Zain SIM card, the number was printed on the card holder or the SIM packaging sleeve. If you still have the original packaging from a Zain store or airport kiosk, the 10-digit number is printed on the back.

Tip: Take a photo of your SIM packaging when you first purchase a new Zain card and save it to your phone’s gallery or cloud storage. This saves time in the future if you ever need to retrieve your number without network access.

Method 8: Contact Zain Customer Service at 959

If all other methods fail, Zain’s customer service team can verify your number after confirming your identity.

1. Dial 959 from your Zain SIM (free call)
2. If calling from another network, dial 0590000959
3. Follow the IVR menu in Arabic or English
4. Select “SIM information” or speak to an agent
5. The agent will ask you to verify your identity (Iqama number or national ID)
6. Once verified, they can confirm your Zain mobile number

Customer service is available 24 hours a day, 7 days a week. Wait times are typically short during off-peak hours (early morning or late evening).

Method 9: Visit the Zain Online Portal

For users with access to a computer or tablet:

1. Go to sa.zain.com and navigate to “My Account”
2. Log in with your registered email address or phone number
3. Navigate to SIM Details or Account Info
4. Your Zain mobile number is displayed alongside other account information

The portal also allows you to manage multiple Zain lines, check data usage across all registered SIMs, and activate or change packages.

Checking All Zain SIMs Registered Under Your Iqama (Saudi Arabia CST Method)

If you want to see every mobile number registered to your identity across all operators in Saudi Arabia, not just Zain, the CST portal provides this at the national level.

Via CST website:

1. Visit citc.gov.sa
2. Select “My Numbers” or the consumer services section
3. Enter your Iqama number or national ID
4. Verify your identity via OTP
5. A list of all SIM cards registered under your name across all Saudi operators appears

This is particularly useful for expats who may have old SIMs from previous stays that are still registered to their Iqama and counting toward the 2-SIM limit enforced by CST regulations.

Via Absher:

• Log in to Absher Individual
• Go to “My Services”
• Select “Communications” or “My Numbers”
• View all SIMs linked to your ID

Troubleshooting: What to Do If *144# Does Not Work

If dialing *144# returns an error or nothing happens, work through these steps:

Check your signal: USSD codes require a live network connection. If you are in a basement, remote area, or an area with poor coverage, move to a location with better signal and try again.

Check which SIM is selected: On dual-SIM phones, confirm the correct SIM is active for the USSD request. Go to Settings, then SIM management, and check which line is set as the default for calls.

Restart your phone: A simple restart clears temporary network errors and resolves most USSD code failures.

Try the alternative code: If *144# fails, try *23# instead. Both codes retrieve the same information and one may work when the other does not.

Send the SMS instead: Switch to Method 3 (blank SMS to 700123) as an immediate workaround.

Check APN settings: If you just inserted a new Zain SIM or switched devices, incorrect APN settings can affect USSD functionality. Contact Zain at 959 to get the correct APN configuration for your device.

For eSIM users: If you are using a Zain eSIM, the USSD code should still work normally. If it does not, try checking through the Zain App instead, which is the most reliable method for eSIM number retrieval.
