du Number Check Code & du SIM Number Check (2026 Guide)
Every du number check code you need is right here — including *116#, SMS to 1355, the My Du app, phone settings, and more — all free, updated for 2026, and working for both prepaid and postpaid users across Dubai, Abu Dhabi, Sharjah, and all seven Emirates.
What Is the Du Telecom Network in the UAE?
Du, officially known as Emirates Integrated Telecommunications Company (EITC), is one of only two major telecom operators licensed in the United Arab Emirates. Launched in 2006, it serves millions of mobile, broadband, and fixed-line customers across all seven Emirates — from Dubai and Abu Dhabi to Ras Al Khaimah, Fujairah, Ajman, Sharjah, and Umm Al Quwain. Whether you hold a prepaid tourist SIM or a long-term postpaid plan, knowing the correct du number check code is one of the most practical things any du subscriber can have memorized or bookmarked.
Du mobile numbers are eight digits long after the UAE country code (+971). Common du carrier prefixes include 050, 052, 055, 056, and 058. It is worth noting that prefixes 050, 055, and 056 are shared with Etisalat, so dialing *116# to confirm your number and identify your network simultaneously is always the smart first step.
Why Would You Need to Check Your Du Number?
There are dozens of everyday situations in which even a long-term resident or regular du user might suddenly need their own number. Some of the most common include:
Sharing your contact with a new employer, landlord, or client when filling in official forms. Registering for government portals, banking apps, or e-commerce platforms that require mobile OTP verification. Activating a new data package, add-on bundle, or promotional offer through du’s self-service system. Verifying your identity when calling du customer support at 155. Porting your du number to another UAE telecom operator if you decide to switch. If you just switched smartphones and your number was not automatically saved in device settings, using the du number check code is the fastest route back to that information without calling anyone or visiting a store.

Method 1: Using the USSD Du Number Check Code *116#
The fastest, most universally recommended approach is to use the official USSD du number check code directly from your phone’s dialer. A USSD (Unstructured Supplementary Service Data) code works at the network protocol level, meaning it functions without internet connectivity, without any credit balance, and on every type of device — from the oldest feature phones to the latest flagship smartphones.
Step-by-step instructions:
- Open your phone’s dial pad or keypad.
- Type *116# exactly as written.
- Press the call or send button.
- Your du mobile number will flash on the screen or arrive as an auto-generated SMS within seconds.
This method works for both prepaid and postpaid accounts equally. However, there is one important caveat for dual SIM users: if you have two SIM cards inserted in your phone, make sure your du SIM is set as the active calling SIM before dialing. Some Android phones will ask which SIM to use when you place the call — always select the du SIM.
iPhone users note: A small number of iPhone users have reported that *116# returns an error when the device is connected to Wi-Fi. If this happens, temporarily disable Wi-Fi, re-dial the code, and the response should come through immediately. sonapur dubai
Method 2: SMS-Based Retrieval
If USSD codes are not responding on your specific device or plan, du offers two equally reliable SMS alternatives. Both are completely free and require no internet connection — just an active du SIM with a valid network signal.
Option A — Send NUMBER to 1355:
Open your messaging app, create a new message, type the word NUMBER (in capital letters), and send it to 1355. Du’s automated system will reply within seconds with your registered mobile number.
Option B — Send getmymsisdn to 9296:
This is a slightly less widely known but officially supported alternative. Type getmymsisdn and send it to short code 9296. You will receive a reply containing your MSISDN (Mobile Station International Subscriber Directory Number), which is simply your du mobile number in telecom terminology.
Both SMS options work with zero balance and are confirmed to function across all Emirates. They are particularly useful if you are currently roaming outside the UAE and cannot use USSD, as long as your data or SMS roaming is active.
Method 3: The My Du App
For smartphone users who prefer a visual, app-based experience, the My Du application provides your number alongside full account management in a single dashboard. This is widely regarded as the most reliable method for eSIM users, since eSIM profiles sometimes cause inconsistent USSD behavior on certain handsets.
How to find your number in the app:
- Download the My Du app from the Google Play Store or Apple App Store if not already installed.
- Open the app and log in using your du account credentials. If you have not registered yet, tap “Register” and follow the prompts using your du mobile number.
- Once logged in, tap on “Profile” or “My Account.”
- Your du mobile number is displayed on the active line card at the top of the account screen.
For users who manage multiple du lines — a common scenario for business account holders — the app allows you to switch between line cards by swiping, so you can verify each number individually. Forgotten your app password? Use the “Forgot Password” option or log in via UAE Pass for a seamless single-sign-on experience.
Method 4: Check Your Phone’s Built-In Settings
Many smartphones automatically store your SIM card’s associated number in the device settings. This is a zero-effort method that requires no codes, no network signal, and no internet — though it only works if your number was correctly saved on the SIM when it was issued.
For Android devices:
Go to Settings → tap “About Phone” or “About Device” → select “Status” or “SIM Status” → look for “My Phone Number” or “SIM Number.” Your du mobile number should appear in this field.
For iPhone (iOS):
Go to Settings → tap “Phone” → the number appears under “My Number” at the very top of the menu.
If the field shows “Unknown” or is blank, this simply means your number was not pre-loaded onto the SIM card — a fairly common occurrence with du prepaid tourist SIMs. In that case, switch to the USSD du number check code method or the SMS alternatives described above.
Method 5: Call or Text a Friend
One of the simplest and most overlooked methods requires no codes at all. Use your du SIM to place a call or send a text message to any contact — a friend, a family member, or even a second phone you own. The number that appears on the recipient’s screen as the incoming caller or sender is your du mobile number.
This is especially handy in situations where USSD codes are failing, your phone settings show an unknown number, and you do not have app access — but you do have signal and a trusted contact nearby.
Method 6: Check the SIM Card Packaging
When du issues a new SIM card — whether a standard plastic nano/micro SIM or a packaged tourist SIM — the mobile number is almost always printed on the physical SIM holder card or on the packaging box. If you still have the original box, envelope, or plastic card that the SIM came in, check the surface of the card or the printed receipt for the 10-digit number beginning with 05.
This is not useful if you discarded the packaging (which most people do), but it is worth a quick check before turning to other methods. Activation SMS messages from du at the time of SIM registration also typically contain your number — scroll back through your inbox to that first-ever du message.
Method 7: Contact Du Customer Service at 155
If all self-service methods have failed — perhaps your SIM is temporarily inactive, USSD codes are returning errors, and you do not have access to the app — calling du’s official customer care number is the guaranteed fallback.
Dial 155 from your du mobile (this call is free of charge within the UAE). Follow the voice prompts and navigate to the account inquiry section, or say “mobile number” to be routed to the right option. A customer service agent is available 24 hours a day, seven days a week, and can confirm your registered number after a basic identity verification, typically involving your Emirates ID number.
If you are calling from outside the UAE or from a different network, the international contact number is +971 55 567 8155.
How to Check Du Number via TDRA Hesabati Portal
The Telecommunications and Digital Government Regulatory Authority (TDRA) operates a service called “Hesabati” — Arabic for “my account” — which allows UAE residents to view all mobile and fixed-line numbers registered under their Emirates ID across every operator in the country, including du, Etisalat (e&), and Virgin Mobile.
This is particularly valuable if you have multiple du SIMs registered under your identity and want a consolidated view. To use it, you need a valid UAE Pass account (the national digital identity platform). Log in to the TDRA portal using your UAE Pass, navigate to Hesabati, and you will see a complete list of all numbers associated with your Emirates ID.
Important privacy note: TDRA’s system only allows you to see numbers registered to your own Emirates ID. UAE privacy law does not permit you — or anyone else — to look up the registered owner of a random du number. If you notice an unfamiliar number registered under your ID in Hesabati, report it immediately through du support or via TDRA for investigation.
Troubleshooting: When the Du Number Check Code Does Not Work
Even the most reliable USSD code can occasionally fail. Here are the most common problems and their solutions:
*“Service Not Available” or no response after dialing 116#
This is the most frequently reported issue. Toggle Airplane Mode on for 10 seconds, then switch it off and try again. On dual-SIM devices, confirm you have selected the du SIM as the active calling SIM. Restarting the phone entirely also clears many temporary network registration errors.
iPhone USSD errors when on Wi-Fi
As mentioned earlier, some iOS devices reject USSD sessions when actively connected to Wi-Fi. Disable Wi-Fi, ensure mobile data is set to the du SIM, and re-dial.
SIM is inactive or suspended
In the UAE, prepaid SIMs that have not been recharged for 90 consecutive days may enter a suspended state. An inactive SIM will not respond to USSD codes or SMS commands. Top up your balance using a recharge voucher or through the du app to reactivate the line, then retry the du number check code.
Roaming outside the UAE
USSD protocols often do not function reliably on foreign networks. The SMS methods (sending NUMBER to 1355 or getmymsisdn to 9296) tend to work better while roaming, provided you have SMS roaming enabled on your plan. Alternatively, connect to Wi-Fi and use the My Du app.
eSIM-specific issues
Users with eSIM profiles should ensure the du eSIM profile is set as “Active” in their device’s cellular settings before attempting any USSD or SMS method. The My Du app is the most consistent choice for eSIM number retrieval.
Du Number Check Code for Prepaid vs. Postpaid Users: Is There a Difference?
A common question among new du subscribers is whether the USSD code or retrieval methods differ between prepaid and postpaid accounts. The straightforward answer is no — the du number check code *116#, the SMS methods to 1355 and 9296, the My Du app, and the customer helpline at 155 all work identically for both account types.
The one difference worth noting is that postpaid subscribers have an additional advantage: their du mobile number is printed on every monthly billing statement and is visible in the My Account section of the du self-care web portal. Prepaid users tend to rely more heavily on USSD and SMS methods since they do not receive regular bills.
What to Do After You Find Your Du Number
Once you have successfully retrieved your number using the du number check code or any of the methods above, take a moment to save it securely to avoid repeating this process:
Save it in your phone contacts under your own name (e.g., “My Du Number”). Take a screenshot and store it in your photo gallery or a cloud backup folder. Write it in a secure note-taking app or password manager. Email it to yourself as a quick reference. For postpaid users, verify that it matches what appears on your bill and in the My Du app for consistency.
Other Useful Du USSD Codes to Know
Since you now know how to navigate USSD on your du SIM, here are a few other codes that du subscribers regularly find helpful:
| Purpose | Code |
|---|---|
| Check account balance | *135# |
| Check data/internet balance | *102# |
| Subscribe to du packages | *135# → follow menu |
| Transfer balance to another number | 121recipient number*amount# |
| Du helpline (free) | 155 |
| International du helpline | +971 55 567 8155 |
Frequently Asked Questions
What is the du number check code in the UAE?
The primary du number check code is *116#. Dial this directly from your du SIM without any internet connection or credit balance, and your mobile number will appear on screen instantly. Both prepaid and postpaid users can use this code.
Can I check my du number without internet?
Yes. Both the USSD method (*116#) and the SMS methods (NUMBER to 1355, or getmymsisdn to 9296) work without internet. These are network-level commands that function on any active du SIM with basic signal coverage.
Is there a charge for using *116# or sending SMS to 1355?
No. Both the USSD code and the official du SMS retrieval methods are completely free of charge and do not deduct any amount from your prepaid balance or postpaid plan.
What should I do if *116# is not working?
First try toggling Airplane Mode, then retry. If you are on a dual SIM phone, ensure the du SIM is selected as the calling SIM. As alternatives, send NUMBER to 1355 via SMS, check your phone settings under SIM Status, or use the My Du app. If nothing works, call du customer service at 155.
Can I find the owner’s name of someone else’s du number?
No. UAE privacy regulations do not permit public lookups of mobile number ownership. You can only confirm the registration of numbers linked to your own Emirates ID through the TDRA Hesabati portal using UAE Pass. For any unauthorized number queries, contact du or TDRA directly.
Does the du number check code work while roaming?
USSD codes like *116# may not function reliably on foreign networks while roaming. The SMS method (NUMBER to 1355) tends to be more dependable while abroad, provided SMS roaming is active on your plan. The My Du app over Wi-Fi is the most consistently reliable option when traveling outside the UAE.
How do I check all SIM numbers registered to my Emirates ID?
Log in to the TDRA Hesabati portal using your UAE Pass account. This government service displays every mobile and fixed-line number registered under your Emirates ID across all UAE telecom operators, including du, Etisalat (e&), and Virgin Mobile.
What are du’s mobile number prefixes?
Du mobile numbers in the UAE use the prefixes 050, 052, 055, 056, and 058 after the country code +971. Note that 050, 055, and 056 are shared prefixes that may also belong to Etisalat subscribers. Using the du number check code *116# is the definitive way to confirm which network your SIM is registered on.
Final Thoughts
Knowing your own mobile number sounds trivial — until you urgently need it and cannot find it anywhere. The du number check code *116# remains the fastest, simplest, and most universally applicable solution for the vast majority of du users in the UAE, delivering instant results with no balance, no internet, and no app required. For situations where USSD is unavailable, the SMS method to 1355 and the My Du app provide equally reliable fallbacks. By keeping this guide bookmarked and the code memorized, you will always have your du SIM information within a few keystrokes — wherever you are in the Emirates.
