If you are working or doing business in the UAE, you will often come across the term UID number. Many people who are new in the UAE get confused between the visa number, Emirates ID Number, and UID Number. Each number serves a different purpose. However, the UID (Unified Identification Number) is one of the most important ones. It links all your immigration records under one ID.
In this guide, we’ll explain what the UID Number in the UAE is. Where to find it (on the Emirates ID, visa, or online) and how to check your UID using GDRFA services. Moreover, why the UID number matters for residents and businesses. Also, where you can get professional support with UAE residency, business setup, or compliance.
What is the UID Number in UAE?
The UID Number stands for Unified Identification Number. It is a unique 9-digit number issued by the UAE’s immigration authorities. When you first enter the country. Dubiz also notes that your UID remains the same even when your visa status changes.
It is assigned by GDRFA and linked to your residency visa, Emirates ID, and immigration file. It is permanent once created, and it does not change. Even if your visa changes or you switch employers. Moreover, it links all your immigration records, entry/exit history, visa files, and residency records.It is used across the Emirates, under a centralised system. So your UID stays valid whether you live in Dubai, Abu Dhabi, Sharjah, or elsewhere. UID is different from your Emirates ID number and your visa number (which is for a specific visa permit).
Where to Find the UID Number in the UAE
You can find your UID Number in several ways:
- On your residence visa / entry permit: printed at the top of the visa, often above the file number
- Sometimes linked with your Emirates ID (or associated in system records)
- Online: via GDRFA Dubai’s “Unified Number Inquiry Service”
- In emirates beyond Dubai: via ICP portals / “File Validity” / unified number inquiry services.
How the GDRFA Unified Number Inquiry Works
The GDRFA offers a free, quick service called Unified Number Inquiry Service so you can look up your UID.

Why Is the UID Number Important?
Your UID is not just a number. It is important in many ways:
- Linking all your immigration history. Including all your entry/exit, visa changes, file transfers are recorded under that one UID.
- Avoiding duplicate records: If your UID is wrong or duplicated, you may end up with multiple immigration records. Which cause confusion and delays.
- Visa & permit processes: When applying for a new visa, renewing one, or canceling, immigration uses your UID to verify your past history.
- Government services: Some services (e.g., verifying file validity, checking fines, linking to your Emirates ID) reference the UID.
- Business & compliance: For companies, having correct UIDs for their employees ensures smooth immigration and labor contracting and avoids errors.
Also, Bestax uses the UID in its business setup processes: when a shareholder holds a visit visa, for instance, you’ll need their unified number.
If your UID is incorrect, mismatched, or lost, many procedures can get delayed or rejected. This is the most dependable way to retrieve your UID if you don’t have your visa or ID at hand.
