Dubai’s DET activity database holds over 2,000 classified activities, each with its own code, licence category, and any sector-specific approval requirements, searchable directly through the Invest in Dubai portal. Changing or adding an authorised activity without prior DET approval carries an administrative fine of AED 2,000, and the reissued licence itself typically arrives within 1-3 business days once an amendment is properly submitted.
This guide covers how to actually choose the right activity code from the start, how adding one later works, and the mistakes that turn a routine amendment into an avoidable fine.
Why the specific code matters more than the general description
Two businesses that both describe themselves as “consulting” can sit under entirely different activity codes depending on the specific type of advice they give, and the code, not the plain-English description on your licence, is what actually determines which approvals apply and what you’re legally permitted to do. A founder choosing a broad, loosely-matching code because it seemed close enough often discovers the mismatch only when a bank, client, or regulator checks the licence against the activity actually being performed.
| Step | Detail |
|---|---|
| Where to search | Invest in Dubai portal, DET’s public activity database |
| Total activities classified | 2,000+, each with its own code |
| Amendment process | DET Basher portal, “Modify Trade License” then “Add Business Activity” |
| Typical processing time | 1-3 business days once submitted |
| Unauthorised activity change fine | AED 2,000 |
“Your licence says what you’re allowed to do in a specific legal code, not in the plain-English sentence you’d use to describe your business to a friend. Those two descriptions don’t always match, and only one of them is enforceable.”
How adding an activity actually works, step by step
The process runs through DET’s Basher portal: log in with UAE Pass or existing DET credentials, select “Modify Trade License,” then “Add Business Activity,” and search the activity database using either the Arabic or English activity name. Where an activity requires external approval from a specific regulator, the portal automatically routes the application to that authority, which is often the step that determines whether the amendment finishes in a few days or takes considerably longer.
Consider a founder whose company was originally licensed purely for management consulting, wanting to add e-commerce retail as a second activity once the business started selling products online. The e-commerce activity code triggered an automatic routing to an additional regulatory check the founder hadn’t anticipated, since retail activities carry different requirements than pure consulting, adding roughly two weeks to what the founder had assumed would be a same-week amendment.
Why some activities need a third-party NOC and others don’t
The DET activity database flags which specific activities require a No Objection Certificate from an external regulator, health authorities for medical-adjacent activities, civil aviation for travel-related ones, and similar sector-specific bodies for others, while a large share of standard commercial and professional activities need no external sign-off at all. Checking this flag before submitting an amendment, rather than after, is what separates a same-week activity change from one that stalls on an external approval nobody budgeted time for.
When an activity change also requires updating your MOA
Depending on your company’s legal form, adding certain activities may require updating the Memorandum of Association alongside the trade licence amendment itself, an extra step that’s easy to miss if the founder assumes the licence update alone covers everything. See our guide on UAE mainland shareholder change process and cost for the fuller notarisation requirements that apply whenever an MOA amendment is genuinely needed, since the same notary process applies here.
Why getting the code right at setup avoids amendment costs entirely
A founder who researches the specific activity code needed before initial registration, rather than choosing the closest-sounding option and planning to correct it later, avoids both the amendment fee and the processing delay entirely. See our guide on how UAE licence categories split between professional and commercial for the broader classification logic that activity codes are built around.
Removing an unused activity is worth doing too, not just adding new ones
A company carrying activity codes it no longer actually performs isn’t just an inaccurate licence; it can complicate bank account reviews, tender applications, and Corporate Tax classification questions where the licensed activity list is checked against actual operations. Removing a genuinely unused activity through the same Basher portal amendment process keeps the licence’s activity list an accurate reflection of the business, which is worth doing periodically rather than only ever adding activities and never trimming them back.
Common mistakes when choosing or changing an activity code
- Selecting a broad, closest-sounding activity code rather than the one that actually matches the business precisely.
- Operating under an unauthorised activity change without DET approval, risking the AED 2,000 fine.
- Not checking whether the new activity triggers an external NOC before submitting the amendment.
- Assuming a licence amendment alone covers a change that also requires an MOA update.
When professional help is worth it
A founder adding a single, clearly-matched activity with no external approval flag can often complete the amendment directly through the Basher portal. Where it’s worth guidance is any activity change that touches a regulated sector, since confirming the correct code and anticipating the external approval requirement upfront avoids weeks of delay on an amendment that looked routine at first glance. e.zone’s activity classification specialists can confirm the right activity code for your business before you submit an application or amendment.
