To check company name availability in Dubai, search the trade name register of the authority that will issue your licence. For a mainland company, that is the Department of Economy and Tourism (DET) trade name service on Invest in Dubai. For a free zone company, use that free zone's own name checker or ask its team. If the name follows the naming rules and no similar name exists, you can reserve it, which usually costs AED 500 to 2,000 and holds the name for about six months.
You have a name in mind, the domain is free and nobody on Instagram is using it. That still does not mean you can register it, and this is where many new founders lose time. In Dubai, only the licensing authority decides whether a company name is available: the Department of Economy and Tourism (DET) for mainland companies, or your free zone authority if you set up in a free zone.
The good news is that you can check company name availability in Dubai before you pay for anything else. This guide shows you where to search, the naming rules that cause most rejections, what reserving a name costs, how long it lasts, and what to do if your name is already taken.
Where to Check: Mainland or Free Zone
The first thing to know is that there is no single company name check in the UAE. Each authority keeps its own register, so where you check depends on where your company will be licensed.
| Setting up in | Who approves the name | Where you check |
|---|---|---|
| Dubai mainland | Department of Economy and Tourism (DET) | The trade name service on the Invest in Dubai portal, the DED Business app, or a DET service centre |
| A Dubai or UAE free zone | That free zone's authority | The free zone's own portal or online name checker, or its setup team |
| Another emirate's mainland | That emirate's economic department | That department's portal |
If you are still choosing between the two, our mainland company setup and free zone company setup pages explain the difference. Settle that first, because a name cleared in one place is not automatically cleared in the other.
Mainland: the DET trade name search
For a mainland trade name in Dubai, the official check is the DET trade name search on Invest in Dubai. You type your proposed name and the system compares it with names already registered or reserved. DET lists the service on its trade name reservation page. Because the database matches on pronunciation, not just spelling, it also flags names that sound like yours in English or Arabic. The DED Business app and DET service centres use the same register.
Free zone company name check
Free zones run their own registers and their own rules. Several offer an online free zone company name check, including Meydan Free Zone and SPC Free Zone. Others ask you to send your shortlist to their team. Keep in mind that a trade name search in Dubai's mainland register tells you nothing about a free zone, and the other way round. The free zone also tells you which suffix your company must use, such as FZE or FZCO.
How to Check Business Name Availability in Dubai, Step by Step
A business name check in Dubai is quick once your shortlist is ready. Follow this order:
1. Write down three to five names you would genuinely be happy with. Make them meaningfully different from each other, not the same name with one letter changed, because similar names fail for the same reason.
2. Run each name against the rules below before you search. Most rejections come from rule problems, not from another company already using the name.
3. Search the official register for your licensing authority. For mainland, use the Invest in Dubai trade name check; for a free zone, use its name checker or ask its team.
4. Check the Arabic version. Every mainland trade name has an Arabic version, and it is checked too.
5. Reserve the name once it clears, and save the reservation certificate. A name that shows as available today is not held for you until it is reserved.
Trade Name Rules in Dubai: What Gets Accepted
Most business name rules in Dubai come from DET's guidelines for mainland trade names. Free zones use similar rules, with a few of their own.
- Use only letters and numbers. Symbols and special characters such as @, & or emojis are not allowed.
- The name must not match or sound like a name that is already registered, or a well-known brand.
- The name cannot be the same as your business activity. The activity is added to the trade name, so "Trading LLC" on its own will not work.
- If you use a person's name, it must be a partner's or owner's full first and last name.
- Names cannot start with "Universal", "International" or "Middle East", or their Arabic equivalents.
- The name must suit your licensed activity and legal form, and end with the right suffix, such as LLC.
Prohibited company names in Dubai
Some names are refused outright under the company naming rules in the UAE, as set out in DET's guidelines. They include names of God or divine attributes, religious sects, names of countries, capitals or governments without approval from the relevant embassy, names of existing organisations, and any word that is offensive or against public decency. Names that use "Dubai", "Emirates" or "Gulf", abbreviations, or foreign words are not banned, but they fall into a premium category with extra review and a higher fee.
Examples: Names That Pass and Names That Fail
Rules are easier to follow with examples. Here is how some names would do in a trade name check in Dubai. The names are made up, but each one shows a common reason for rejection.
| Proposed name | Result | Why |
|---|---|---|
| Al Mansoori Properties LLC | Rejected | Surname only; a personal name needs a first and last name |
| Khalid Al Mansoori Properties LLC | Can be accepted | Full name of an owner or partner |
| International Tech Solutions LLC | Rejected | Starts with "International" |
| Star@Home Trading LLC | Rejected | Contains a special character |
| General Trading LLC | Rejected | Same as the business activity |
| Dubai Prime Logistics LLC | Premium review | Uses "Dubai", which needs extra approval and costs more |
| Nova Bloom Flowers Trading LLC | Likely accepted | Distinctive, fits the activity, if no similar name exists |
Can I Use My Own Name as a Company Name in Dubai?
Yes, as long as you use your full first and last name and you are an owner or partner in the company. "Ahmed Khan Consultancy" works; "Khan Consultancy" does not. Using someone else's name, or a famous person's, will be refused.
Getting the Arabic Trade Name Right
Every mainland company has an Arabic trade name in Dubai, and it is usually written by sound, not by meaning. "Nova Bloom" becomes the Arabic letters for "Nova Bloom", not a translation of the words. Two names that look different in English can be identical in Arabic, and that alone can lead to a rejection. Ask for the Arabic spelling at the check stage and keep one approved version for your licence, signboard and bank documents.
What Happens If My Company Name Is Taken in Dubai?
If your trade name is rejected in Dubai, you are told the reason and can submit a new name. What you should not do is add one letter or a hyphen and try again; the pronunciation-based check usually catches it. Change the distinctive part of the name instead, or add a real word that makes it different.
If the name is taken because it is your own brand from another country, ask the authority what proof it needs. A registered trademark in your name can help your case, though approval is still the authority's decision.
Trade Name Reservation in Dubai: Cost and Validity
Once your name clears, you reserve it. Here is how to reserve a trade name in Dubai: submit the name through the same portal, app or centre you used for the check, pay the fee, and you receive a reservation certificate. For mainland companies, this usually goes hand in hand with the initial approval from DET.
| Item | What to expect |
|---|---|
| Trade name reservation cost in Dubai | AED 500 - 2,000, depending on the authority and the type of name |
| Higher end of the range | Premium names, such as foreign words, abbreviations or names using "Dubai", "Emirates" or "Gulf" |
| Trade name reservation validity in Dubai | Usually six months for DET; check the expiry on your certificate |
| If no licence is issued in time | The reservation is cancelled and the name is released |
Free zones set their own reservation fees and validity, and many include the reservation in the setup package. To see the full picture, check our business setup cost guide.
Trade Name vs Trademark vs Domain Name in the UAE
This is where many founders get caught out. A trade name, a trademark and a domain are three separate things, and owning one does not give you the others.
| Trade name | Trademark | Domain name | |
|---|---|---|---|
| What it is | Your company's legal name on the licence | Protection for your brand, logo or product name | Your website address |
| Who issues it | DET or your free zone | UAE Ministry of Economy and Tourism | A domain registrar |
| Where it applies | With the authority that licensed you | Across the UAE | Online only |
So, does a domain name reserve my company name? No. Buying a .ae or .com domain, or claiming social media handles, has no effect on trade name availability in Dubai. The same is true the other way round: an approved trade name does not stop someone else from registering your brand as a trademark. If the brand matters, apply for a trademark early, before you print anything.
Can I Change My Company Name in Dubai Later?
Yes. You can change a company name after the licence is issued by applying for a licence amendment with your licensing authority. The new name goes through the same check and rules, and you will need to update your bank, visa and contract records afterwards. It is easier to spend an extra day choosing the right name now.
After the Check: Business Name Registration in Dubai
Reserving the name is the first step of company setup, not the last, and it is not the same as registering the firm. Once the name is reserved, you move on to activities, documents and the licence itself. Firm name registration in Dubai is only final when the licence is issued under that name, so keep the reservation date in mind while you prepare the rest.
- Choose your business activities so they match the name.
- Prepare passports and other papers using our documents required for business setup checklist.
- Sort out an office or flexi-desk, depending on mainland or free zone.
- Apply for the licence before the name reservation expires.
