If you’re living, working, or doing business in the UAE, chances are you’ve heard about the Unified Identification Number (UID). Whether you’re applying for a visa, renewing your residency, or processing official paperwork, the UID plays a critical role in your journey through the UAE’s immigration system.
This guide will walk you through everything you need to know about the UID number in 2025—from how to find it, to what it’s used for, and how to handle duplicate UID numbers.
🧾 What is a UID Number in the UAE?
The Unified Identification Number (UID) is a unique code issued to all expatriates by the General Directorate of Residency and Foreigners Affairs (GDRFA) during their first immigration application—be it for a residence or work visa.
🟢 Key features of the UID number:
- Assigned once, stays with you permanently
- Separate from Emirates ID and visa numbers
- Used across all immigration and residency processes
- Helps streamline background checks, renewals, and cancellations
Think of it as your permanent immigration fingerprint in the UAE system.
🔍 How to Find Your UID Number
Your UID number is usually printed on your UAE residence visa sticker in your passport.
Steps:
- Open your passport to the visa page
- Look for the label “Unified Number”
- Note down the 9–15 digit number listed next to it
💡 Tip: Still can’t find it? Try checking online through the ICP portal (instructions below).
🌐 How to Check Your UID Number Online
The UAE government has made checking your UID number simple and digital.
✅ Steps to check your UID online:
- Visit the ICP portal
- Choose the “File Validity” option or UID inquiry
- Enter your passport number, nationality, and personal details
- View your UID instantly
🛡 Always save your UID number—it will be needed for future immigration, work permit, or visa-related tasks.
🧾 How Is the UID Number Assigned?
You don’t need to apply for a UID number manually. It’s automatically generated by UAE immigration when:
- You apply for a residence/work visa
- Your employer or sponsor submits your entry permit request
Once issued, your UID stays the same—even if you cancel your visa or change sponsors later on.
🛠 What Is the UID Number Used For?
Here’s why your UID number matters:
- ✅ Residency Visa Applications & Renewals
- ✅ Amendments or Cancellations of Visas
- ✅ Labor Contracts & Work Permits
- ✅ Immigration Background Checks
- ✅ GDRFA Records Management
In short, it ties your entire immigration history to a single, consistent identity.
🔢 What Do the Digits in Your UID Number Mean?
Your UID might look like a random set of numbers, but it’s formatted with structure:
- First few digits may reference the year or immigration system
- Remaining digits are your unique identity in the GDRFA database
There’s no public decoding method—but each UID is guaranteed to be unique.
🧩 Can You Have More Than One UID Number?
Yes—and that can lead to issues. Multiple UID numbers can occur if:
- You entered the UAE under different visa types (tourist vs. work)
- You had different sponsors across different periods
- You applied under a new passport
💡 Problem: This can cause confusion with visa renewals or Emirates ID processes.
🔄 How to Merge Multiple UID Numbers
Got two UID numbers? Don’t worry—merging them is straightforward.
Steps to merge UID numbers:
- Visit a GDRFA or ICP office
- Bring:
- Passports (old and new)
- Emirates ID
- Residence visa copies
- Request UID merging
- Wait for confirmation (usually within a few working days)
This process ensures all your records fall under one consistent UID, reducing administrative hassles.
