Understanding the UID Number: A Complete Guide To Find Your Unified Identification Number in the UAE

Most people in the UAE know their Emirates ID, but not their UID number. Yet this code is just as important. It’s the key that links your visa, Emirates ID, medical tests, and immigration records together.

Your Unified Identification Number (UID) is issued the first time you enter the UAE on a residence visa. You’ll find it printed on your visa stamp inside your passport, usually as a nine-digit number above the visa file number.

So why does it matter?

You’ll need your UID for processes like visa renewals, Emirates ID applications, and medical screenings. Without it, these steps can get delayed or rejected.

We’ll break down exactly what it is, where to find it, and why it matters for your residency and business setup in Dubai.

Understanding the UID Number in the UAE

The Unified Identification Number (UID) is a unique 9–15 digit code assigned to every individual who enters the UAE on a residence visa.

Unlike your visa or Emirates ID, which are issued for fixed periods and need to be renewed, the UID is permanent.

It stays the same throughout your time in the UAE, even if you change employers, switch visas, or re-enter the country after leaving.

This is what makes the UID different.

• Visas are tied to your residency status and expire when your residency period ends, whether that’s two, three, or five years.
• Emirates IDs are also issued with expiry dates that match the length of your visa. Once your visa expires, you’ll need a new Emirates ID.
• The UID doesn’t expire and doesn’t change. It remains linked to your immigration record for life, acting as your permanent reference number in the UAE system.

You’ll need it for key steps like visa renewals, Emirates ID applications, or medical tests.

The Importance of UID Number in the UAE

If you are staying in the UAE, your UID number is important. Here’s why it matters:

• Track your movements: The UID number helps immigration and visa departments to track your entry and exit movements. It also links multiple visa applications under a single profile.
• Easy government process: The UID number acts as a central reference across all government data base. It allows easy retrieval of personal records for government authorities.
• Integration of services: The UID number is required for your Emirates ID application, visa renewals, medical tests and residency visa stamping. It connects services like health insurance, residency permits and labour contracts.
• Easy business set up: When you start a company in the UAE, your passport is usually all you need to begin the application. Once your UID number is issued, it becomes the unique link between your visa, Emirates ID, and trade license. At Meydan Free Zone, we use this UID to connect and verify all your records instantly.
