Best Ways to Check DU Number Owner in the UAE (2025 Guide)
Whether you’re receiving calls from an unknown number or you’ve found an old SIM card and would like to determine the identification of the owner, knowing how to check the owner of a Du number in the UAE will come in handy. However, due to strict laws on privacy in the UAE, telecom companies like Du are not permitted to reveal subscriber information, and rightly so.
That said, if you are the account holder or can demonstrate that you have a valid purpose to determine or confirm ownership information for a DU number, there are legitimate and efficient ways to do so.
Use the UAE’s TRA Registered Mobile Number Portal
The UAE government has introduced a centralized system called the ICP Smart Services portal, where you can find out how many SIMs (from any telecom provider like Du, Etisalat, Virgin, etc.) are registered under your Emirates ID.
How to Use It:
- Visit the ICP Smart Services Portal.
- Under Check Registered Mobile Numbers, click Start Service.
- Enter your Emirates ID number as well as your date of birth.
- Complete the CAPTCHA and proceed.
The system will now provide you with a list of all active mobile phone numbers that are registered in your name. This doesn’t include the names of an unknown number, but it helps you check:
- Whether a number is registered under your ID.
- If your ID has been misused for unauthorized SIMs.
Call Du Customer Support
If the phone number belongs to you, or if you are registered to the account as an account holder for your family member, you can call Du’s customer care and request to verify ownership.
Du Customer Care: 155 (within UAE) or +971-4-390-5555 (outside UAE).
Requirements:
- You must have your Emirates ID or passport that is linked to the phone number.
- You will need to answer verification questions (e.g., recent recharges, last number dialed, etc.).
- They will likely tell you if the phone number is under your ID or not.
Note: Du will not share another person’s name or ID due to privacy regulations.
Visit a Du Outlet or Authorised Dealer
If you think your Emirates ID is misregistered to a SIM, or if you just want to deactivate phone numbers that you do not know, you can go to a Du branch with your original Emirates ID.
They can:
- Determine how many Du numbers are registered to your ID.
- Deactivating SIM cards that you don’t use.
- Assist you with recovering a number if it was yours previously.
What You Cannot Do Legally
You cannot actively search and reveal another person’s name or ID of the owner, unless you have a legal reason. Any app or website that claims you can see owner details, such as Truecaller, is not to be trusted and likely violates privacy protections. Telecom companies will not publish subscriber details unless there is an official police complaint or court order.
File a Police Report
If You Want to File a Police Report (In the Case of Harassment or Fraud). If you’re getting threats or spam calls or maybe a scam from a Du number, you can inform the local police.
Dubai police E-crime platform: https://www.ecrime.ae
After complaining:
The police can work with Du to legally identify the owner of the number. You may be notified if formal actions proceed. This is the only LEGAL way to identify a number that has been used to harass or for fraud.
Use Truecaller as a General Hint
Truecaller isn’t official, but it can sometimes provide user-supplied names or business tags for numbers. It’s not completely reliable, but it might provide a hint.

You simply need to enter the Du number and look for a profile name or a tag.
WARNING: Don’t use Truecaller for privacy-sensitive matters or legal decisions. Truecaller is a crowd-sourced database and not an official government registry.
Watch out for Fake Lookup Services
There are lots of websites claiming to be able to identify the owner of a mobile number in the UAE. They are mostly scams, phishing, or some sort of nonsense.
Avoid:
- Clicking on suspicious UAE number search link ads
- Paying for premium number look-up tools with no official governance
- Sharing your Emirates ID or personal info on such platforms
Conclusion
In a country like the UAE, where digital privacy and identity verification are taken seriously, there is no public directory available online to check the name of a Du number owner. And that is a good thing, protecting residents and visitors.
As the registered user, you have the right to check the numbers registered under your Emirates ID and act if you have been registered under a SIM without your knowledge. If you are a victim of harassment or fraud, the legal route through the police and due diligence with the telecom authority may be the safest and most prudent course of action.
