Frequently asked questions
How do I get a Dubai mainland trade licence?
Mainland licensing through DET typically involves choosing your activity, reserving a trade name, obtaining initial approval, completing documentation and Ejari, then collecting the licence. Steps vary by activity and legal form.
What is the difference between DED and DET?
DET is the current name for what many still call the DED (Department of Economic Development). It is the same Dubai authority for economic licensing, now under the Department of Economy and Tourism.
How do I renew a DET trade licence?
A mainland licence is renewed through DET, usually requiring a valid Ejari tenancy and settlement of any fees. Alwahaa can prepare and submit the renewal on your behalf.
