du Directory UAE: 181 Enquiries, 155 Support & Charges (2026)
Quick answer: For a published UAE telephone listing, the national directory-enquiry number is 181. For help with a du mobile account, use 155 from your du line or the support options on du’s official contact page. Directory enquiries and customer care are different services; 199 should not be presented as du’s general mobile-support number.
Choose the service by the question you need answered. Finding a listed business number is a directory task. Fixing a bill, SIM registration, failed recharge or account access requires the operator that manages your line.
181 or 155: which number do you need?
| Your task | Correct starting point | What to prepare |
|---|---|---|
| Find a published telephone listing | 181 national directory enquiries | Business or subscriber name and location |
| Get help with a du mobile service | 155 from a du mobile, or du’s official contact page | Your du number and a clear description of the problem |
| Contact du from overseas | Use the overseas number currently shown on the contact page | Country code, account details and possible international call charges |
| Resolve a home-internet issue | Choose the home-service channel on du’s contact page | Account number, router status and service address |
| Identify an unknown private caller | Your operator’s nuisance-call or fraud-reporting channel | Call time, displayed number and any suspicious message |
How to make a useful directory enquiry
- Write down the exact business name and emirate; a branch or street name helps narrow the search.
- Dial 181 and explain that you want a directory listing, not technical support.
- Read the returned number back before ending the call, then check the organisation’s own website where possible.
- For a bank, government service or payment request, use the number published on its official site rather than trusting an unsolicited caller.
A listing is not proof that a caller is genuine. Fraudsters can claim to represent a real company, and the number shown on an incoming call is not a reliable identity check.
Directory fees: avoid assuming the call is free
Directory enquiries can be chargeable. e&’s published customer-affairs code lists a successful 181 enquiry at AED 1 plus VAT. That published rate is not a promise about what every du tariff, roaming connection or overseas network will charge. Ask du about the charge applicable to your line if the cost matters, and check the bill afterwards.
Do not confuse the cost of an enquiry with the cost of calling the number you receive. An international, premium-rate or special-service number can have a separate tariff.
What a directory cannot tell you
A telephone directory is a consent-based listing service, not a reverse-lookup tool for private people. The published directory policy does not provide a subscriber’s private name and address merely because you supply a phone number. No legitimate directory guide can guarantee the identity of an unknown mobile caller.
Get account help without a directory call
- Open the du app or My Account for bills, usage and service management.
- Use the official support page to choose live chat, mobile support or a store.
- For a failed payment, keep the transaction reference and date; do not send your full card number or security code.
- For a complaint, ask for a case reference and retain the response so follow-up staff can find the same issue.
Never approve an unexpected UAE PASS request or disclose an OTP to someone who calls you. Start the conversation through a channel you independently verified.
Questions readers ask
Is 181 a du customer-care number?
No. Treat 181 as national directory enquiries. Use du’s mobile-support channel for a problem with your du service.
Can I use 199 for du support?
The current official du mobile-support information identifies 155. Use that guidance rather than an old or unsourced 199 recommendation.
Does du have a public reverse-number directory?
Do not assume its account portal can identify private callers. The portal is for managing your own service.
What if the listed business number does not work?
Check the organisation’s official website for a current branch contact. Directory listings and branch details can change.
