If you’re in the UAE and scrambling to check your DU number, you’re far from alone.
Whether you’re setting up WhatsApp, filling out an Emirates ID form, or just forgot to save it after inserting a new SIM…we’ve all been there. And yes, it’s a little annoying when the number isn’t just right there.
So, Team Marhabein put together the most complete guide on how to check your DU number step-by-step, using official methods only, with real-life use cases baked in.
And we’ve made sure it answers your every question.
What is a DU Number & Why You Might Need It
To begin with, let’s understand what is a DU number.
A DU number is your mobile number provided by DU Telecom—one of UAE’s two main telecom providers (the other being Etisalat). It’s a unique identifier linked to your SIM and your national ID in the UAE telecom system. This number is very important for several reasons.
You’ll need your DU number for:
- Linking your Emirates ID
- Setting up apps like WhatsApp or Careem
- Online shopping deliveries
- Two-factor authentication
- Porting your number to another provider
Common Situations Where People Need DU Number:
Sure, your DU number’s main job is to keep you connected but that’s not all! There are plenty of everyday situations in Dubai where knowing your number is absolutely essential.
Take one of our team members, for example, she picked up a brand new DU SIM and completely forgot to save the number. Relatable, right?
Here are a few other common scenarios we’ve come across:
- Your DU number is saved in someone else’s contacts but not in yours. (It happens more often than you’d think.)
- You’re using a DU SIM just for mobile data, so you never really needed the number until now.
- You found an old DU SIM in your drawer and want to check if it still works or is linked to any accounts.
6 Official Ways to Check Your DU Number
Here’s the full list of verified methods to check your DU number in 2025 each with when to use it and what to expect.
1. Dial the DU Number Check Code: `*135#`
Insert your DU SIM in any phone and dial `*135#`. You’ll immediately see your number on the screen.
Why this method is great to check your DU number:
- No balance required
- Works on any phone (smart or feature)
- Takes 5 seconds
When to use it:
Perfect if you don’t have Wi-Fi or data and just need a quick result.
But remember: This method won’t work if the SIM is inactive or blocked.
2. Check via DU App (My DU)
1. Download the My DU App from App Store
2. Log in with your DU credentials
3. Go to “My Account” or Profile. You’ll find your number listed right there.
When this method works best:
If you’ve already set up the app or have internet access, this method is smooth and visual.
Pro Tip: You can manage billing, data usage, and recharge from here too.
3. Ask DU via Live Chat (No SIM Required)
1. Visit: https://www.du.ae/personal
2. Tap the Chat icon in the bottom-right
3. Start a chat. Ask “How can I find my number?”
4. You may need to confirm some identity details
Why this method is helpful:
Works to check your DU number even if you don’t have the SIM inserted, or if it’s inactive.
Best for:
People with a lost number or inactive SIM who still want to retrieve it without using USSD or app.
4. Send a Message or Call a Friend
- Insert the DU SIM
- Call or send a short SMS to someone you trust
- Ask them to read the number that popped up
Pros:
- Doesn’t need any codes or apps
- Good if your balance is low but you have calling/SMS available
But Remember: This method is not the best if your SIM has no credit or is new.
5. Check the SIM Starter Pack or E-Receipt
- SIM cardholder or physical pack
- DU purchase confirmation email
- Online account or MyDU login (web)
When to use this method:
Great if you just got the SIM from a kiosk or store and have the packaging nearby.
Trust tip: Your DU number is also linked to your Emirates ID. So your phone number may appear in government-linked portals (like ICA or Tawtheeq), but those aren’t always up to date.
6. From Phone Settings (Caution: May Not Work)
- If you have an iPhone, go to Settings, then Phone, then My Number
- For Android users, go to Settings, then About Phone, then Status, SIM Status, and then My Phone Number
Why this method is tricky:
Sometimes it shows “Unknown,” especially for DU and Etisalat SIMs. Not 100% reliable.
DU vs. Etisalat: How Number Check Differs
You might be wondering what’s the difference in the procedure to check your DU number vs Etisalat numbers. Well, DU’s number check code is `*135#`, while Etisalat users dial `*248#’.
We mention this because many UAE residents switch between both networks or use dual SIM phones.
Remember: If neither code works, you’re probably on the other provider!
Still Have Questions about DU number? Let’s Clear Them Up
We’ve answered some of the most common (and honestly, most Googled) questions people have when trying to check their DU number, no tech-speak, just real talk.
“Can I check my DU number if I don’t have balance?”
Yes, you totally can check your DU number. Just dial *135# and your number will pop up. It’s free, no credit needed, and works on both smartphones and those good old Nokia-style phones.
“What if my DU SIM isn’t inserted in a phone?”
In that case, your best bet is DU’s Live Chat via their website. You’ll just need to verify a few details and the agent can help you out. You can also log into your DU account online if you have access to it.
“I think my SIM’s inactive… is there still hope?”
Maybe! If it hasn’t been deactivated permanently, DU can often help revive it. Just hop on the live chat or visit a DU store with your Emirates ID. They’ll let you know what’s possible.
“Isn’t there an SMS trick to check the number?”
Ah yes—the old “send ‘getmymsisdn’ to 9296” method. It used to work a while back, but in 2025, it seems to be phased out. Stick with *135# for now—it’s the most reliable option that’s still active.
