All You Need to Know UAE UID Number and Identification Key
The UAE - a place where business opportunities, tourism and residency all come together under one roof. If you're trying to make sense of the country's admin scene - whether you're a newcomer, setting up a business or just back from a stint abroad - there's one number that takes precedence: the Unified Identification Number (UID).
This permanent number is the single most important part of your identity in the UAE's system & you'll be amazed at how easily it gets mixed up with a different number - the Emirates ID or the Visa File Number. The result? Long, frustrating delays when trying to process your visa, set up your business or access government services. This guide is here to help break it all down: what the UID actually is, why it matters, where to find it and just how it compares to identity systems elsewhere in the world - take the US for example.
Your UID Number: A Permanent & Unchanging Identity in the UAE
Your Unified Identification Number (UID Number) is a one-off, unique code that gets assigned to you the moment you arrive in the UAE and go for an entry permit or residency. The ICP (Federal Authority for Identity, Citizenship, Customs, and Port Security) or the GDRFA (General Directorate of Residency and Foreigners Affairs) in Dubai are the ones who issue these unique codes.

UID vs. Emirates ID vs. Visa File Number
Understanding the distinction between these three numbers is the first step to seamless government interaction:

The key takeaway: The UID number is like your permanent, unchanging social security number within the UAE’s immigration database, while the Emirates ID and Visa File Number change with renewals.
The Lowdown on UID Numbers: Finding Your Unified Number on Your Visa
For residents, the UID is pretty straightforward to find on your official residency documents.
Where Can You Spot Your UID Number?
-
On the Residence Visa (That Sticker or E-Visa): The UID number is right there on the visa sticker or e-visa document, typically near the top, and separate from the "File Number" or "Visa Number". Look for the label "Unified Number" or "UID".
-
Online: If you're waiting for your visa or have lost those physical documents, you can jump online and check your UID via the official government portals of the ICP or GDRFA (for Dubai). Just need your Passport Number, Nationality, and Date of Birth to snag your Unified Number from your record.
The UID number is super important for all the next steps, especially the Emirates ID Application, because the Emirates ID can't be processed without a confirmed UID.
What's So Critical About the UID Number for UAE Residents and Businesses?
The UID number is more than just a reference; it's the key to your whole legal existence in the UAE.
1. Backing Up Your Residency and Visa Processing
Every little thing, from applying for a visa as an investor or employee to sponsoring your family, relies on the UID number. It makes sure the government has all your up-to-date, accurate immigration history, saving time and speeding up approvals. But any mix-up or duplicate UID can instantly raise a flag and stop a visa application dead in its tracks.
2. Business Setup and Licensing
For anyone starting a company in the UAE Mainland or Free Zone, the UID is essential for:
-
Investor Visa Application: It links you to the company’s license.
-
Setting up an Establishment Card: The company’s immigration file needs the partners’ UIDs.
-
Employee Sponsorship: The UIDs of all employees get tracked through this system.
3. Government and Banking Services
The UID is how you get verified for government and banking services, like:
-
Opening a personal or corporate bank account.
-
Applying for a credit card or loan.
-
Logging onto online government services (like healthcare, utilities, and driving license services).
Global Perspective: The UAE's UID - Not the Same as a US Visa Number
The UAE's UID gets mixed up all the time with other countries' IDs, especially the United States. We're about to clear up the confusion.
What's the Visa Number on a US Visa?

The US visa system's got its own unique ID numbers and none of them are called a "UID" like the UAE. Let's start by setting the record straight.
-
US Visa Number (or Visa Foil Number): That's the main ID number you'll find on the physical visa sticker stuck in your passport.
-
Location: It's usually written in red ink on the bottom right corner of that visa sticker.
-
Format: It's an eight-digit number and it often starts with a letter.
-
What it's for: It's what US Customs and Border Patrol use when they check you at the border to make sure your visa is valid.
-
What is a UID Number in the US?
People are often getting their wires crossed when they search "what is uid number visa" and "UID" in the US - because there are a couple of different numbers they could be talking about:
-
Alien Registration Number (A-Number): This is a seven- to nine-digit number that the US gives to immigrants who apply for things like a Green Card - it's the closest thing to the UAE's permanent UID because it keeps track of an immigrant's whole US history. But the US calls it an A-Number, not a UID.
-
CGI/Consulate Tracking Number (What Some People Call a "UID"): Back when you're trying to book a visa appointment and pay the fees online, you get a unique tracking number on the US Consulate's website (CGI). Some folks call this a "UID", but it's actually just a temporary number to track your case - it's not your official visa or immigration number.
Technical Note: Don't Get Confused with Unix User ID
The phrase "check user ID Linux" sounds a lot like something else - the technical Unique Identifier used by operating systems. When you search for that term, you're probably not looking for how to troubleshoot your computer - you're actually after the Unique Identifier used by Linux and Unix systems.
In the world of Linux and Unix, every user account gets a unique number called a User ID (or UID) and a group number called a Group ID (GID). These numbers, like 1000 or 1001, are what the operating system uses to control who can do what, who owns what files, and who gets access to what. Its got nothing in common with that other thing.
Conclusion: Using Your UID to Live in the UAE like a Pro
The UID Number is basically your ticket to making things happen in the UAE. Whether it's securing your residency or setting up a business, this special code is what ties everything together across the UAE's super-smart, interconnected government services. Grasping what the UID is all about and how to work with it is going to be super helpful if you want to live a hassle-free, compliant, and super successful life in the Emirates.

FAQs
Q1: Is the UAE's UID number the same as a US visa number?
A: No way. The UAE UID Number is a permanent, unique identifier for your whole UAE immigration and residency history. A US visa number (or visa foil number) is a specific, eight-digit number printed on the visa sticker in your passport, used to check if it's valid for entry into the US. They are two completely different identifiers for two different countries.
Q2: Where can I find the visa number on my US visa, and what is it?
A: Your visa number is also known as the visa foil number, and it's a unique identifier on your US visa stamp. It's usually written in red ink on the bottom right corner of the visa, and it's made up of eight characters - a mix of numbers and sometimes a letter.
Q3: What is a UID number visa in the context of a US visa application?
A: The term "UID number visa" isn't an official US identifier. If you come across it during a US visa application, it probably means you'll see a CGI or Consulate Tracking Number, which is a unique code given to your case on the appointment scheduling website - for example, for fee payments or appointment changes. And that's not your visa number, which is on the final sticker.
Q4: If I have a US visa, do I need a separate UID number for the UAE?
A: Yes. A US visa is completely separate from your UAE residency. If you enter the UAE and apply for a residence permit - for work, investment or family sponsorship - the UAE authorities will assign you a brand new, unique and permanent UID Number for their system.
Q5: How is the US A-Number (Alien Registration Number) different from the UAE UID?
A: Both are permanent tracking numbers, but for different countries. The UAE UID is assigned to all residents to track their residency/immigration history in the UAE. The US A-Number is assigned to non-citizens applying for long-term US immigration benefits, such as Green Cards or certain permanent statuses, to track their US immigration record.
