Forgot your du mobile number? First check your phone’s SIM settings, your signed-in du account, or the details that came with your SIM. If those do not show it, du customer care can help you identify the line after verifying your account. Several websites recommend dialing *116#, but I could not confirm that particular number-check function from current official du documentation, so do not rely on it as a guaranteed method.
This guide explains how to check your du number in the UAE on Android or iPhone, with and without balance or internet. It also separates your mobile phone number from the serial number printed on a SIM card, which is not the same thing.
How to Check Your du Number: The Fastest Reliable Methods
Start with whichever method you already have access to. You do not need to install another app if your number appears in your phone settings, an existing du account, a bill or the documents supplied with your line.
- Look in your phone settings. On an iPhone, check your mobile line information in Settings. On Android, open About phone or the SIM section. Names differ between devices, and the phone-number field may be empty.
- Open an already signed-in du account. du confirms that its app and My Account service support account management and profile information. If you already have access, review the linked accounts or profile and identify the correct mobile line.
- Check your SIM documents or bill. Look for a mobile-number field on an activation confirmation, account record or monthly bill. Do not mistake the SIM serial number (ICCID) for your callable number.
- Ask du support if needed. From a working du line dial 155; from another phone call +971 555 678 155. Have your account or identity information ready for official verification, but do not share it in public comments.

du Number Check Code: Is There a Working USSD Code?
Search results for “du number check code” often show *116# and tell readers to call it from a du SIM. This recommendation appears across several independent UAE guide websites, but I could not find a current official du page confirming that dialing it displays your own number. It has not been tested on a live du SIM for this guide. Treat it as an unverified suggestion, not an official or guaranteed service.
A different code, *135#, appears in du’s prepaid self-service information. That does not prove it provides a “show my number” feature. A prepaid balance or service menu and an own-number lookup are not necessarily the same thing.
If a code you found elsewhere displays a network error, does nothing or opens a different menu, stop trying random short codes. Select the correct du line on a dual-SIM handset and use the account, phone settings or official support routes instead. USSD requires a compatible active mobile-network connection; it is not an internet or Wi-Fi service.
How to Find Your du Number in the du App or My Account
du officially directs customers to the du app or My Account to manage their services. Its support documentation says the My Account profile can show a primary contact number and linked account information. This method is useful when you have already signed in.
- Open the official du app, or use du’s My Account website in your browser.
- Sign in using a method available to your existing account. Do not assume a new user can log in without knowing the phone number or completing account verification.
- Review your account or profile information, and check any linked mobile lines. If several numbers are linked, identify the exact line you need.
- If you cannot access the account, use the official in-app support option or contact du instead of creating duplicate accounts.
This option needs internet access and an account you can reach. It may work over Wi-Fi even when you have no prepaid credit, as long as you can sign in. The precise position of the phone number may change with app updates, so this guide does not claim an unverified button name or screen location. Official du information also explains that the app can manage plans, usage and support.
How to Check Your du Number on Android
Many Android phones can store and display a mobile line’s phone number, but the exact menu differs between Samsung Galaxy, Google Pixel and other brands. Some handsets show a number under Settings → About phone, while others place SIM details under Network & internet, Connections or SIM manager.
- Open Settings on the Android phone holding your du SIM or enabled du eSIM.
- Look for About phone, SIM status, or the mobile network/SIM-management menu. Choose the du line if the phone has two SIMs.
- Look for a field such as Phone number or Mobile number. Write down the displayed number only if it clearly belongs to the correct line.
If the number says Unknown or is blank, that does not by itself mean the SIM has stopped working. Some SIM and device combinations simply do not supply the number to the Android settings screen. Move to the du account or support method instead. Your SIM serial number is not a substitute for your mobile number.
How to Check Your du Number on iPhone
On iPhone, your mobile-line information may be visible under Settings → Phone on some iOS versions, or under Settings → Cellular/Mobile Service for individual SIM and eSIM lines. Apple changes some settings labels across iOS versions and regions.
- Open the iPhone Settings app.
- Check Phone, or open Cellular / Mobile Service and select the relevant du line.
- Look for the line’s phone number or account information. On a dual-SIM iPhone, confirm you are viewing the du line rather than another provider.
If your number is missing, check a bill or an existing du account. Do not enter made-up digits into a settings field to “fix” the display. An iPhone eSIM can have a plan label without showing an easily readable phone number, so the plan label alone is not proof of the number assigned to it.
How to Check Your du Number Without Balance or Internet
You may still have practical options when your prepaid balance is zero. Phone settings and any documents already stored or printed do not need a recharge. An existing du account can be checked using Wi-Fi, provided you can sign in. Do not assume that ordinary calls or text messages will work with zero balance; availability depends on your service status and the type of call.
| Method | Internet needed? | Phone balance needed? | What must be available? |
|---|---|---|---|
| Phone settings | No | No | Device with correct SIM/eSIM; number may not display |
| SIM packaging or account paperwork | No | No | Document that actually lists your mobile number |
| Existing du app/My Account | Yes, Wi-Fi can be used | No recharge necessarily | Access to the registered account |
| Customer support | Depends on channel | Call charges/availability vary | Official account verification |
| USSD number-check code | Mobile network, not internet | Not verified | No officially confirmed own-number code in this guide |
If you have no internet at all, start with offline phone settings, saved documents or your original SIM packaging. Another option is asking du support from a different working phone. The du app and browser account are not offline tools. If the phone has no cellular signal, a USSD request cannot communicate with the network.
Why Is My du Number Not Showing?
When a number does not appear where expected, check which part of the process is failing instead of immediately replacing the SIM. The following checks help separate a device display issue from a service or account problem.
| Problem | Useful next step |
|---|---|
| Android says “Unknown” | Check another account record or ask du; the number field may simply be unavailable. |
| Wrong number appears | Confirm which physical SIM or eSIM is selected in dual-SIM settings. |
| SIM not detected | Check that the SIM is correctly fitted or that the eSIM plan is enabled. Restart the device if appropriate. |
| New SIM not connecting | Follow the official du SIM setup instructions and contact support if activation has not completed. |
| du app asks for a number you forgot | Use an already signed-in account or ask du to help verify the registered line. |
| USSD code returns an error | Check the active du line and signal; use verified alternatives rather than guessing codes. |
If you recently moved from a physical SIM to an eSIM, confirm that the correct profile is enabled on the phone. You should also distinguish a line’s phone number (used by people to call you) from the SIM card number or ICCID (a technical identifier printed or stored with the SIM). Both can be useful to support staff, but they serve different purposes.
How to Contact du Customer Care
du’s official SIM information lists 155 for calls from a du phone and +971 555 678 155 from another phone. It also provides +971 4 800 155 for roaming support and the email customer.care@du.ae. Check the current du contact page before using a number found elsewhere.
du says it also offers chat assistance through official digital channels. Explain that you need to identify the number on your own SIM or eSIM. The adviser may need to verify that you own the line before sharing account details. Never post identity documents, verification codes or full account numbers in a public forum.
Frequently Asked Questions
What is the du number check code in UAE?
Several independent guides suggest *116#, but I could not verify that it displays your number using current official du documentation. If you need a dependable answer, check your phone settings, an existing du account or contact du support.
Can I check my du SIM number without balance?
Yes, you can check saved SIM or account documents and look in your phone settings without recharging. You may also access an already signed-in du account over Wi-Fi. Whether a support call works depends on the service and available calling route.
Can I find my du number without internet?
Try offline phone settings or paperwork that lists the mobile number. These methods do not rely on internet access, but settings do not always show the number. If neither works, contact du from another available phone.
Can I use the du app to see my number?
The official app supports account management, and du describes account profile and linked-account information in its support material. If you are signed in, review your accounts or profile. A new login may require details or verification you do not have.
Why does my phone show “Unknown” for my du number?
The phone may not have the number stored in its SIM information, even when the line is working. Check that the correct line is selected, then use your du account or official support to confirm the number.
Is my SIM serial number the same as my mobile number?
No. The SIM serial number, commonly called ICCID, identifies a SIM, while your mobile number is the number callers dial. If a form asks for your du mobile number, do not automatically copy the serial number printed on the SIM card.
Final Thoughts
The easiest reliable approach is to start with your device settings or a du account you can already access. For users without balance or internet, saved documents and offline settings may help. If your number is still missing, du customer care can verify your account and advise the next step.
