How to Update Your DEWA Mobile Number, Email or Account Details
Update DEWA contact, premises or landlord details through the correct digital or service channel and complete identity verification.
Start with the official rule
DEWA customers can update a registered mobile number, email address, PO box and certain premises or landlord details. Contact changes can be completed through the website or app after verification, while other record changes may require supporting documents and manual review.
Step by step
1. Choose one detail to change
Identify the exact mobile, email, PO box, premise or landlord field. DEWA’s digital flow may update one contact item at a time, so finish and verify one before starting another.
2. Use the official account channel
Sign in through DEWA’s website or app, select the update service and complete the identity or cross-verification step. Do not give a verification code to a caller.
3. Open the verification promptly
Use the verification link sent to the registered contact within its stated validity period. DEWA currently says the link remains valid for 24 hours.
4. Track a manual update
For premises or landlord details, upload the requested evidence and retain the request number. DEWA lists up to three working days for these updates after a complete submission.
Important: Changing contact details does not transfer the utility account or replace move-in, move-out or tenancy procedures. Use the correct separate service when occupancy changes.
Before you act
Digital contact updates are listed as free. A PO-box update through email or the customer contact centre can carry a service fee. Check the current channel and fee before submitting.
