Your UID is a permanent identification number assigned by UAE immigration the first time you’re ever issued a visa, and it never changes again, no matter how many times you renew, switch sponsors, or change visa types.
This guide covers what it is, how to find it, and how to fix it if something’s gone wrong.
What Is a Unified Number (UID)?
The UID, short for Unified Identification Number, is generated automatically the moment your first UAE visa is processed, whether that’s a tourist visa, an employment visa, or an investor visa. It’s a permanent record, not tied to any single visa, sponsor, or passport.
Where a visa number or file number resets with every renewal or new application, your UID stays fixed for life. It’s the one constant thread that links your immigration history together across every visa you ever hold in the UAE.
Who Issues It and Who Gets One
Two authorities issue and manage UIDs, split by emirate. The General Directorate of Residency and Foreigners Affairs (GDRFA) handles Dubai-issued visas, while the Federal Authority for Identity, Citizenship, Customs & Port Security (ICP) handles the other six emirates: Abu Dhabi, Sharjah, Ajman, Umm Al Quwain, Ras Al Khaimah, and Fujairah. You can read up about this split on the official UAE government portal.
Everyone gets one, regardless of visa type. Tourists and visit visa holders receive a UID the moment their entry permit is issued, just like employees, investors, and dependents. Children born in the UAE or brought here on a family visa get their own separate UID too.
Unified Number vs Emirates ID vs Visa or File Number
These three numbers get confused constantly, and mixing them up on a government form is one of the more common causes of delays.
What Each Number Is For
Which Numbers Change and Which Stay the Same
The UID never changes, regardless of visa renewals, sponsor changes, or job switches. Your visa or file number changes every time a new visa is issued. Your Emirates ID number itself stays with you for life, the same way your UID does. What actually changes at renewal is the separate card number printed on the back of the physical card, not the ID number itself.
Where to Find Your UID (Visa, Entry Permit, eVisa, Emirates ID)
The most reliable place to find your UID is your visa document itself, whether that’s a physical visa sticker, an entry permit, or a digital eVisa PDF. It’s labelled “Unified Number” or “UID” and sits just above your file number.
If you’re a tourist or visit visa holder, the same label appears on your entry permit. Whether the UID also appears on the physical Emirates ID card varies by source and card version, so if you can’t find it there, your visa document remains the most dependable place to check.
How to Check Your Unified Number Online
If you don’t have a visa copy handy, several official portals let you retrieve your UID directly.
Check via GDRFA (Dubai)
For Dubai-issued visas, use the GDRFA Unified Number Inquiry Service directly on the official GDRFA Dubai website.
Check via ICP File Validity (All Other Emirates)
For visas issued in any other emirate, use the File Validity tool on ICP Smart Services, accessible through the official u.ae portal, which links directly to the correct ICP inquiry page.
Check via the UAEICP, UAE Pass and DubaiNow Apps
The UAEICP app mirrors ICP’s online services and gives ICP-registered users their visa and UID details from their phone. UAE Pass and DubaiNow both let you log in with your digital identity and pull up visa and residency details, including your UID, from one place without needing to search a separate portal.
Details You Need and Reading the Result
Most inquiries ask for your passport number, nationality, date of birth, and gender. Once submitted, the result displays your UID alongside your current visa or file details.
If You Get “No Record Found”
This usually means you’ve used the wrong portal for the emirate that issued your visa. A Dubai-issued visa won’t show up on ICP, and a non-Dubai visa won’t show up on GDRFA. Double-check which authority actually issued your visa before assuming there’s a data problem, and try entering your details again carefully, since a single mismatched digit is enough to return no result.
How You Get a UID
Visit and Tourist Visas
Your UID is generated automatically the moment your entry permit or tourist visa is approved, even for a short stay. Most tourists never need to look it up, but it exists in the system from day one.
Residence Visas
If you’re applying for your first UAE residence visa, your UID is created at that point, unless you already hold one from an earlier visit or visa, in which case your existing UID carries forward.
Newborns in the UAE
A child born in the UAE, or brought in on a family visa, is assigned their own UID once their first visa or Emirates ID application is processed. It’s entirely separate from a parent’s UID, even though the two files are linked administratively.
Why the UID Matters for Individuals and Businesses
Personal Use (Emirates ID, Visa, Government Services)
Your UID is referenced behind the scenes for Emirates ID applications, visa renewals, medical insurance verification, and various government services, even when you’re not asked to type it in directly.
Business Use (Trade License, Establishment Card, Labour Quotas)
For business owners, the UID links your personal immigration file to your company’s establishment card, trade license paperwork, and labour quota records. A PRO or business setup consultant handling your visa and license paperwork will need it on file; our business setup guide covers where this fits into the wider registration process.
Unified Number by Scenario (Employee, Dependent, Investor)
Duplicate or Multiple UIDs and How to Merge Them
Why Duplicates Happen
Duplicate UIDs usually happen when someone applies for a new visa without their existing UID being correctly matched to their file, often across different visa types or after a gap between visits.
Documents You Need
To resolve a duplicate, you’ll generally need your passport, copies of your current and any previous visas or entry permits, and your Emirates ID if one has already been issued.
If you’d rather have someone else manage the paperwork trail, our team can handle your documentation needs through our premium business support services, SPC Plus.
How to Merge with GDRFA or ICP (In Person and Online)
For Dubai-issued visas, this is handled through GDRFA, either at a service centre or through their online channels. For all other emirates, it’s handled through ICP, either at a service centre or through ICP Smart Services. Either way, it’s worth raising the issue as soon as you notice it rather than after several more visa cycles have passed.
After the Merge: Update Your Records
Once your UID is merged, check that your Emirates ID, bank records, and any employer or PRO paperwork are updated to reflect the single, correct UID, since some of these may still reference the old, duplicate number until manually corrected.
Best Practices for Keeping Your UID Consistent
Always use your UID specifically where a form asks for it, rather than substituting your visa or file number, since the two aren’t interchangeable and mixing them up is a common cause of rejected applications. Keep a digital copy of your visa or eVisa saved somewhere accessible, and flag any discrepancy the moment you notice it rather than letting it carry through multiple renewal cycles.
How SPC Free Zone Helps with UID Support
Getting your UID wrong on a single form can hold up a visa, a bank account, or a license renewal, and untangling it after the fact takes longer than getting it right the first time.
Our documentation service and dedicated account manager handle this kind of detail as part of your ongoing visa and licensing support, so a mismatched UID doesn’t become your problem to solve alone.
If you’re setting up a business here, our VIP medical and Emirates ID service also keeps this process moving quickly from the visa stage onward.
Your UID sits quietly behind almost everything you do administratively in the UAE, and the moment it’s wrong or duplicated, that becomes obvious fast. Getting it right early, and knowing exactly where to check it, saves real time later.

Frequently Asked Questions
Is the UID the same as the Emirates ID number?
No. The UID is your permanent immigration identifier. Your Emirates ID number is a separate permanent number tied to you personally, while the physical card’s own serial number, printed on the back, is what actually changes when the card is renewed or replaced.
Where is the UID on a UAE visa?
It’s labelled “Unified Number” or “UID,” positioned just above the file number on your visa document or eVisa.
Do tourists and visit visa holders get a UID?
Yes. A UID is generated automatically the moment an entry permit or tourist visa is issued, even for short stays.
How many digits is the UID?
There’s no single published digit count. It varies by issuance date and no UAE authority publishes an official format, so don’t assume a UID is invalid because it looks shorter or longer than one you’ve seen elsewhere.
Does the UID change or expire?
No. It’s permanent and stays the same for life, regardless of visa renewals, sponsor changes, or job switches.
Can a person have two UID numbers?
Yes, though it’s not meant to happen. Duplicates usually result from an administrative mismatch and should be merged through GDRFA or ICP as soon as they’re noticed.
How do I find my UID without a visa copy?
Use the GDRFA Unified Number Inquiry Service for Dubai-issued visas, or the ICP File Validity tool for any other emirate, entering your passport number, nationality, date of birth, and gender.
Is the UID the same as the visa file number?
No. The file number is specific to your current visa and changes with every renewal, while the UID is permanent and never changes.
Is the UID confidential?
Treat it as sensitive personal information. It shouldn’t be shared beyond what’s needed for official immigration, banking, or licensing procedures.
