Whether you just activated a new Du SIM card, switched from another UAE telecom provider, or simply haven’t memorized your number yet, this complete 2026 guide walks you through every available method — from USSD codes and SMS shortcuts to the Du app and customer support — so you can retrieve your Du mobile number in seconds.
What Is Du Telecom?
Du (officially known as Emirates Integrated Telecommunications Company, or EITC) is one of the two major telecom operators in the United Arab Emirates, alongside Etisalat (now e&). It serves millions of prepaid and postpaid subscribers across Dubai, Abu Dhabi, Sharjah, Ajman, Fujairah, Ras Al Khaimah, and Umm Al Quwain.
Du offers mobile, broadband, home internet, and enterprise services, making it one of the most widely used SIM networks in the UAE. For new users especially, finding your Du SIM number is one of the first things you need to do.
Why You Might Need to Check Your Du Number
There are several everyday situations where knowing your Du mobile number becomes essential:
- Filling out government forms or online applications that require your contact number
- Registering for banking, healthcare, or e-commerce services
- Sharing your number with employers, colleagues, or family
- Verifying your identity with Du customer support
- Activating a data package, promotional bundle, or roaming plan
- Porting your number to another network
- Checking your Du balance, usage, or account details
In all of these situations, using the du number check code is the fastest way to retrieve your mobile number on the spot.
Method 1: Du Number Check via USSD Code — The Fastest Way
The quickest and most universally recommended method to check your Du number is by dialing a USSD (Unstructured Supplementary Service Data) code directly from your dial pad. This is the same du number check code that works across both prepaid and postpaid plans.
Steps:
- Open the dial pad on your smartphone or keypad phone
- Type *116#
- Press the call or send button
- Your Du SIM number will appear on the screen within seconds
This method works without an internet connection and does not require any credit balance on your SIM. It is compatible with all types of phones — whether you use an Android, iPhone, or a basic keypad handset. positive vibes quotes
Why this method is preferred:
- Completely free of charge
- No internet or mobile data required
- Works on both prepaid and postpaid Du accounts
- Displays the result instantly on screen
- Available across all seven Emirates
Method 2: Check Du Number via SMS
If the USSD method does not work on your device, you can retrieve your number by sending a free SMS. This is another reliable du number check code alternative that works without any balance.
Option A — SMS to 1355:
- Open your phone’s messaging app
- Create a new text message
- Type the word: NUMBER (in capital letters)
- Send the message to 1355
- You will receive an automatic reply containing your Du mobile number
Option B — SMS to 9296:
- Open the messaging app
- Type: getmymsisdn
- Send to 9296
- An SMS reply with your number will arrive within seconds
Both SMS options are free, require no internet, and work on any mobile phone type.
Method 3: Check Du Number Using the Du App
For smartphone users, the Du mobile app provides a convenient way to view your number, manage your account, and monitor usage all in one place.
Steps:
- Download the Du app from the App Store (iOS) or Google Play Store (Android)
- Sign in using your Du account credentials or UAE Pass login
- Navigate to Profile or My Account section
- Your Du mobile number (MSISDN) will be displayed on the active line card
This method also gives you access to your billing history, data usage, recharge options, and active plan details. If you’re using an eSIM or have multiple SIM lines registered, each number will be listed separately.
Method 4: Call or Text Another Phone
A simple and no-tech approach to verifying your Du SIM number is to make a call or send a text to someone you know.
Steps:
- Use your Du SIM to call a trusted contact — a friend, family member, or colleague
- Ask them to check the incoming caller ID on their screen
- Your Du number will appear on their phone
Alternatively, send yourself a message using a different device to see your number as the sender. This method is useful when USSD codes are temporarily unavailable or when your SIM has low or no balance.
Method 5: Contact Du Customer Service
If none of the self-service methods work, Du’s 24/7 customer support team can assist you in retrieving your number after verifying your identity.
How to reach Du support:
- From your Du mobile: Dial 155 (free of charge)
- From abroad or another network: Call +971 55 567 8155
- Via Du app: Use the live chat feature within the app
You may be asked to verify your identity by providing your Emirates ID number or passport details. A customer service representative will then confirm your Du mobile number and any other registered SIM details on your account.
Method 6: Check Your Phone Settings
Modern smartphones store your SIM number in the device settings, and you may be able to find your Du number there directly — no calling or messaging required.
On Android:
- Go to Settings
- Tap About Phone or SIM Card & Mobile Network
- Look for Phone Number or SIM Status
- Your Du number may be displayed here
On iPhone (iOS):
- Open Settings
- Tap Phone
- Select My Number
- Your Du SIM number should appear
Note: This field may be blank or show an incorrect number depending on the device and how the SIM was programmed. If it appears empty, use the USSD or SMS method instead.
Method 7: Check the SIM Card Packaging
If you still have the original packaging your Du SIM came in, your mobile number is typically printed on the card holder or the activation sheet inside the box. This is particularly useful if you have not yet inserted the SIM into a device.
Look for a label with the format: 05X XXX XXXX — this is your Du UAE mobile number.
Method 8: Use the TDRA Hesabati Portal
The Telecommunications and Digital Government Regulatory Authority (TDRA) in the UAE provides a service called Hesabati, which lets you view all SIM numbers registered under your Emirates ID — regardless of the network provider.
How to access Hesabati:
- Visit the official TDRA portal
- Log in using your UAE Pass or Emirates ID credentials
- View all SIM cards (Du, Etisalat/e&, Virgin Mobile) registered in your name
This method is especially useful if you manage multiple SIM cards or need to verify your SIM registration for official purposes.

Du Number Format in UAE
Understanding the structure of a Du UAE number can also help you confirm whether the number shown is correct.
- UAE country code: +971
- Du carrier prefixes: 050, 052, 055, 056, 058
- Full format example: +971 52 XXX XXXX or 052 XXX XXXX
Note that the prefix 050, 055, and 056 is shared between Du and Etisalat, so the prefix alone does not confirm your network. However, using the du number check code instantly removes any doubt.
Other Useful Du USSD Codes
Beyond the du number check code, Du provides several other USSD shortcuts for managing your account without needing internet access or the app:
| Service | Code |
|---|---|
| Check Du number | *116# |
| Check Du balance (prepaid) | *135# |
| Check active data package | *135*2# |
| Check remaining data balance | *135*5# |
| Recharge prepaid credit | *121*recharge pin# |
| Du customer care | 155 |
Save these codes on your phone or write them somewhere accessible — they’re especially helpful when you’re traveling or your internet connection is unavailable.
Du Prepaid vs Postpaid — Does the Method Differ?
The good news is that the du number check code works the same way for both prepaid and postpaid Du customers. Whether you’re on a monthly contract plan or a pay-as-you-go prepaid SIM, dialing *116# or sending an SMS to 1355 will return your number accurately.
The primary difference between the two account types comes when managing your plan:
- Prepaid users can top up via the Du app, USSD recharge codes, or retail stores
- Postpaid users can manage billing and plan changes through the Du app or customer service
For home internet subscribers, the Du app is the recommended method since a home router does not have a traditional mobile number in the same format as a SIM card.
Common Problems and Troubleshooting
What if *116# doesn’t work?
If the USSD code returns an error or no response, try the following:
- Make sure your Du SIM is active and not suspended
- Restart your device and try again
- Try the SMS method (send NUMBER to 1355) as a backup
- Contact Du customer support at 155 for assistance
What if the number shown in phone settings is wrong?
Phone settings pull the number from data stored on the SIM, which is sometimes outdated or incorrect. Always rely on the USSD or SMS method for the most accurate result.
My Du SIM is inactive — can I still check my number?
Inactive or suspended SIMs typically do not respond to USSD or SMS commands. You will need to reactivate or top up the SIM first, or contact Du customer support to retrieve the number on record.
