If you live, work, invest, or do business in the UAE, you will often be asked for your UID number. Many people confuse it with their visa number or Emirates ID number, but these are not the same. Your UID, also called the Unified Identification Number or Unified Number, is the immigration reference that connects your UAE entry, visa, residency, and identity records under one file.
This guide explains what the UID number in UAE means, where you can find it, how to check your UID online through GDRFA or ICP services, and why it matters for employees, residents, investors, shareholders, and companies handling UAE visa or business setup paperwork.
What is the UID Number in UAE?
The UID Number stands for Unified Identification Number. It is a unique immigration number created for a person when they enter the UAE or when their visa record is created in the immigration system. It is also commonly called the Unified Number.
Your UID is different from your Emirates ID number and your visa number. The Emirates ID is your official identity card as a UAE resident, while the visa number is linked to a specific visa or residence permit. Your UID works more like a master immigration file number. It helps UAE immigration authorities connect your entry permits, residence visas, renewals, cancellations, Emirates ID applications, and other immigration records under one reference.
In most cases, the UID remains the same even if your visa changes, your employer changes, your passport is renewed, or your residence visa is cancelled and later renewed. That is why it is important to use the correct UID when completing UAE immigration, residency, business setup, or employee visa processes.
Where to Find the UID Number in the UAE
You can usually find your UID number in one of these places:
1. On Your UAE Visa or E-Visa Copy
Your UID is usually shown near the top section of your UAE visa, entry permit, or e-visa copy. It may appear as “UID,” “Unified Number,” or “Unified No.” Do not confuse it with the visa file number, passport number, or Emirates ID number.
2. Through the GDRFA Unified Number Inquiry Service
If your visa or immigration record is linked to Dubai, you can use the GDRFA Dubai Unified Number Inquiry Service. This service allows you to find your UID by entering your passport number, nationality, date of birth, gender, and security check details.
3. Through ICP Smart Services or UAEICP App
For Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah, and Umm Al Quwain records, you can check your visa and identity details through ICP Smart Services or the UAEICP app. These platforms are commonly used for visas, residencies, Emirates ID services, fine payments, and related immigration services.
4. Through Emirates ID Records
Your UID is connected with your Emirates ID record in the UAE system. However, do not assume that the number printed on the front of your Emirates ID card is your UID. The 15-digit number starting with 784 is your Emirates ID number, not your UID. If you need the actual UID, check your visa/e-visa copy or use the official GDRFA or ICP services.
How to Check UID Number Online Through GDRFA
If your record is connected with Dubai immigration, you can check your UID through the GDRFA Dubai Unified Number Inquiry Service.
Here is the simple process:
- Visit the official GDRFA Dubai website.
- Open the Unified Number Inquiry Service or Find Unified Number service.
- Enter your passport number exactly as written on your passport.
- Select your nationality.
- Enter your date of birth.
- Select your gender.
- Complete the security check.
- Submit the form to view your UID number.
Make sure the passport number, nationality, and date of birth match your official documents. Even a small spelling or number mistake can stop the system from showing the correct UID.
How to Check UID Number Through ICP or UAEICP App
If your UAE visa or residence record is not issued through Dubai, you may need to check your details through ICP Smart Services or the UAEICP app. ICP manages identity, citizenship, passports, entry, and residence matters for the UAE at the federal level.
You can usually use ICP services to check visa validity, Emirates ID status, residency details, and related records. The UAEICP app also allows residents and visitors to access visa, residency, Emirates ID, fine payment, and other ICP services from their mobile phone.
When checking your details, keep these documents ready:
- Passport number
- Passport expiry date
- Nationality
- Date of birth
- Emirates ID number, if available
- Visa or application reference number, if available
If the UID does not appear or your details do not match, it is better to contact ICP directly or visit an authorised service centre instead of using random third-party websites.
Why Is the UID Number Important?
Your UID number is important because it connects your immigration history in the UAE. It helps government systems identify your visa, residency, entry, exit, and Emirates ID records under one reference.
For individuals, the UID may be needed when applying for or renewing a residence visa, checking immigration records, applying for Emirates ID, updating personal information, or correcting visa-related details.
For businesses, the UID is important when processing employee visas, investor visas, partner visas, shareholder records, labour-related documentation, and free zone or mainland company setup paperwork. If the UID is wrong, duplicated, or mismatched, it can delay visa approvals, Emirates ID applications, employee onboarding, and other compliance work.
That is why residents, employers, investors, and business setup consultants should always verify the UID before submitting important immigration or company documents.
UID Number vs Emirates ID Number vs Visa Number
Many people confuse the UID number, Emirates ID number, and visa number. They are connected, but they are not the same.
| Detail | UID Number | Emirates ID Number | Visa Number |
|---|---|---|---|
| Main purpose | Immigration file tracking | Official UAE identity card number | Specific visa or residence permit reference |
| Who gets it | Visitors, residents, employees, investors, and visa holders | UAE residents | Visa holders |
| Does it change? | Usually remains the same | Can change with card records/renewals depending on system updates | Can change when a new visa is issued or renewed |
| Where to find it | Visa/e-visa copy, GDRFA, ICP records | Printed on Emirates ID card | Visa/e-visa or immigration file |
| Used for | Immigration records, visa processing, Emirates ID linking, business setup paperwork | Identity verification, banking, telecom, government services | Visa validity, sponsor/employer and residence permit records |
The simple way to understand it is this: your UID is your immigration identity reference, your Emirates ID is your resident identity card number, and your visa number belongs to a specific visa record.
Common UID Number Issues in the UAE
1. Duplicate UID Numbers
Sometimes a person may have more than one UID because of an old entry record, passport change, visa change, or administrative error. This can create confusion during visa processing, Emirates ID applications, or immigration checks. If this happens, the records may need to be reviewed and merged through the relevant immigration authority.
2. UID Not Showing Online
If your UID does not appear online, first check that your passport number, nationality, date of birth, and gender are entered correctly. Also try checking with your old passport details if you previously entered the UAE using another passport.
3. UID and Emirates ID Details Do Not Match
Your UID and Emirates ID are connected in the system, but they are not the same number. If the records do not match, it may affect visa renewal, Emirates ID updates, or official applications. In this case, contact GDRFA, ICP, Amer, or an authorised service centre.
4. New Passport, Same UID
If you renew your passport, your UID normally remains the same. However, your new passport details should be updated in the immigration system so your UAE records stay correct.
5. Confusing UID with Visa File Number
The visa file number and UID are different. The UID is used to connect your immigration records, while the visa file number is related to a particular visa or residence file. Always check the label before entering the number on government or company forms.
6. Using Third-Party Websites
Avoid entering your passport, Emirates ID, or visa details on unknown websites. Use official UAE government portals, authorised apps, or trusted professional service providers only.
How Businesses, Free Zones, and Employers Use UID Numbers
UID numbers are not only important for residents. They are also useful for companies, free zones, employers, investors, and shareholders in the UAE.
When a company applies for an employee visa, investor visa, partner visa, or shareholder-related immigration process, the UID may be required to identify the person correctly in the UAE immigration system. This helps avoid duplicate files, wrong visa records, and delays in approvals.
Businesses may need UID details for:
- Employee residence visa applications
- Investor or partner visa processing
- Shareholder records during business setup
- Free zone immigration files
- Emirates ID applications
- Visa renewals, cancellations, and amendments
- Labour and immigration compliance records
- Corporate bank account or KYC documentation in some cases
If the UID is incorrect, the application may be delayed, returned, or rejected. This is one reason many business owners work with consultants like Bestax when handling company formation, visa processing, immigration coordination, and compliance paperwork in the UAE.
UID Number in Dubai, Abu Dhabi, Sharjah, and Other Emirates
The UID number is used across the UAE, but the online service you use may depend on where your visa or immigration record is issued.
For Dubai-related records, GDRFA Dubai is usually the main authority for checking the unified number, visa services, residency services, fines, and other immigration matters.
For Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah, and Umm Al Quwain, ICP Smart Services and the UAEICP app are commonly used for identity, visa, residence, Emirates ID, and related services.
Even if you move between Emirates or change your employer, your UID normally remains connected to your immigration identity. What may change is your visa sponsor, visa file, employer, free zone, or residence permit details.
UID Number and Businesses in the UAE
For employers and investors, the UID Number is crucial for:
- Employee residency visa applications.
- Compliance with immigration records.
- Linking business owner records across multiple companies.
That’s why many companies rely on business setup consultants like Bestax to manage visa processing, UID verification, and immigration compliance.
