Check your number using a USSD code
The fastest way to check your Du number is by dialing a USSD code from your Du SIM. Open your phone dialer, enter the Du number check code, and follow the instructions shown on your screen.
Du users can check their mobile number by dialing:
*Dial: 116#
Your Du number should appear on your phone screen if the service is available for your SIM.
If the code does not work, try restarting your phone and checking again. USSD services may sometimes fail because of temporary network issues, SIM problems, or phone settings.
You can also check available Du self-service codes through the official Du website because service codes may change over time.
Find your number through the mobile app
You can check your Du number from the Du mobile app after logging into your account.
Steps:
- Download and open the Du app from your phone’s app store.
- Sign in using your Du account details.
- Your registered mobile number will appear in your account information.
- You can also view your plan details, balance, and active services.
The app method is useful if you manage more than one Du number under the same account. It also helps you keep track of your SIM services without remembering different codes.
You need an internet connection to use the app. If you cannot log in, use another method such as the USSD code or phone settings.

Check your number by SMS
Some users try to find their Du number through SMS services. However, Du does not provide a general SMS number-check method that works for all customers.
If you cannot use a USSD code or app, other options include checking your phone settings, calling another phone, or contacting Du customer support.
Avoid sending messages to unknown numbers or third-party services that claim to reveal your SIM number. They may not be official and can put your information at risk.
Call or message another phone to reveal your number
A simple way to find your Du number is to call another mobile phone nearby. Your number will appear on the other person’s screen if caller ID is active.
You can also send a message to another phone and check the sender number.
This method works well if:
- Your SIM has enough balance for calls or messages.
- Another phone is available nearby.
- Your caller ID settings are not hidden.
If your number does not appear, check your phone settings or use an official Du account method.
What is a Du mobile number and why do you need to check it?
A Du mobile number is a UAE phone number provided through a Du SIM card. It allows users to make calls, send messages, access mobile data, and use digital services connected to their identity.
People often need to check their Du number in these situations:
- After buying a new SIM card.
- When using multiple SIM cards.
- Before sharing their contact details.
- During online account registrations.
- When recharging a prepaid SIM.
- When linking services to a mobile number.
Your mobile number is also connected to your SIM registration details. In the UAE, SIM cards are registered using valid identification documents, such as an Emirates ID for residents.
Different methods to check your Du number
There are several ways to find your Du number if the quick methods do not work. You can check your phone settings, look at your SIM documents, or contact Du support.
Each method works differently depending on your phone model, SIM condition, and account access.
Check your number from Android phone settings
Android phones may display your SIM number in the settings menu, but the location depends on the device brand and Android version.
Try these steps:
- Open Settings on your Android phone.
- Go to About phone or Phone information.
- Select SIM status or SIM card status.
- Check the phone number section.
Some Android devices may show “Unknown” because the number is not stored on the SIM card. This does not mean your SIM is damaged. It only means the phone cannot read the number from the SIM information.
If the number does not appear, use the Du code method or check through your account.
Check your number from iPhone settings
iPhone users can check their Du number through the phone settings.
Follow these steps:
- Open Settings.
- Scroll down and select Phone.
- Look for My Number.
- Your saved mobile number will appear there.
You can also check:
Settings > Apple Account > Sign-In & Security > Phone Numbers
The displayed number depends on the information saved on your device or SIM. If it is missing or incorrect, update it manually or use another Du verification method.
Simple Codes To Check Your Du Number Faster
Forgot your Du mobile number? You can usually find it within seconds using the Du number check code *116#. This method does not normally require mobile data and is one of the quickest options for checking your number.
Check Your Du Number Using *116#
The easiest way to check your Du number is through USSD.
Du number check code: *116#
Follow these steps:
- Open your phone’s Dialer.
- Enter
*116#. - Press the Call button using your Du SIM.
- Your Du mobile number should appear on the screen.
USSD works through the mobile network, so you generally do not need mobile data to use the code.
Quick tip: If *116# does not work, check that your Du SIM is active and connected to the Du network, then try again. You can also use the Du app, phone settings, or your SIM documents.
Use *135# for Du Self-Service
Du also provides *135# as a self-service USSD menu for prepaid customers. It can be used to manage services such as balance, recharges, bundles, and other account options.
Dial: *135# → Press Call → Follow the on-screen options.
Because *135# is a general self-service menu rather than specifically a number-check code, use *116# first when your goal is simply to find your Du number.
Check Your Du Number Without Balance or Internet
If your Du SIM has no balance or mobile data, you can still try *116# because USSD operates through the mobile network.
Other options include:
- USSD: Dial
*116# - Du self-service: Dial
*135# - Android: Settings → About Phone → SIM Status
- iPhone: Settings → Phone → My Number
- Du App: Log in and check your account details
- SIM packaging: Check the original SIM card package or activation documents
If your phone has two SIMs, make sure you select the Du SIM before sending the USSD request.
Find Your Number on the SIM Packaging
If you recently purchased your Du SIM, check:
- SIM card packaging
- Activation receipt
- Purchase confirmation SMS
- Documents provided by the retailer
Your assigned mobile number may be included in these details. If you replaced your SIM or no longer have the original packaging, use *116# or another method instead.
Contact Du Customer Support
If *116# does not work and you cannot find your number through your phone or account, contact Du support.
Du customer care: 155 when calling from a Du number.
From another phone: +971 55 567 8155.
You can also use the Du app, online support, or visit a Du store. You may need your Emirates ID or other identification details to verify account ownership.

How to Check Du SIMs Registered Under Your Emirates ID
If you want to know which mobile numbers are registered under your identity, this is different from simply checking the number of the SIM currently in your phone.
For ownership or registration questions, use official UAE government or telecom-provider services and complete the required identity verification.
Keep your Emirates ID, account details, and other personal information secure. Never share OTP codes, passwords, or Emirates ID details with unknown people.
