The Unified Number UAE (also known as UID — Unified Identification Number) is a unique identifier assigned to every individual registered in the UAE immigration system. Whether you are a resident, an employee, or a visa applicant, understanding your Unified Number is essential for navigating government services, renewing visas, and processing documents across UAE federal entities.
In this complete guide, we explain exactly what the Unified Number is, who needs it, how to find it, and how to resolve common issues — all updated for 2025.
What Is the Unified Number (UID) in UAE?
The Unified Number is a unique reference number issued by the UAE Federal Authority for Identity, Citizenship, Customs and Port Security (ICP) — formerly GDRFA at the federal level. It is assigned to every individual who enters the UAE immigration system: expatriate residents, visa applicants, and dependants.
The Unified Number is sometimes referred to as:
- UID Number (Unified Identification Number)
- ID Number on older immigration documents
- Person File Number in some GDRFA records
This number persists across visa renewals, employer changes, and even if you leave and re-enter the UAE. It is a permanent identifier tied to your biometric records in the UAE immigration database.
Who Needs a Unified Number and Why?
Every person with a UAE residency visa, employment visa, investor visa, or dependent visa has (or will receive) a Unified Number. You need it for:
- Processing employment visa applications through the e-Channel system
- Renewing or cancelling your UAE residency visa
- Applying for or renewing an Emirates ID
- Medical fitness test registration
- Labour card applications (MOHRE)
- Sponsoring family members
- Opening bank accounts and signing tenancy contracts (some banks and landlords request it)
- Accessing ICP self-service portals
Employers also use employees’ Unified Numbers when processing visa applications via the e-Channel online portal. Without it, transactions in the system cannot be completed.
Unified Number vs Emirates ID Number vs Visa Number
Many people confuse these three numbers. Here’s the key difference:
| Number Type | What It Is | Format | Where Found |
|---|---|---|---|
| Unified Number (UID) | Permanent immigration ID tied to your biometric record | Typically 10–15 digits | Visa stamping page, ICP portal, AMER centres |
| Emirates ID Number | National ID card number — changes each card cycle | 784-YYYY-XXXXXXX-X (15 digits) | Front of Emirates ID card |
| Visa Number | Reference number for a specific visa issuance | Varies by visa type and emirate | Visa stamping page in passport |
Key point: Your Emirates ID number changes every time you renew your card. Your Unified Number never changes. The Visa Number is specific to one visa issuance only.
How to Get Your Unified Number — Step by Step
If you are a new entrant to the UAE immigration system, your Unified Number is automatically generated when your visa application is processed for the first time. Here’s how it works:
- Visa application submitted — Your employer or PRO submits your employment visa via ICP or e-Channel.
- Entry permit issued — ICP processes the application and issues an entry permit. A Unified Number is generated at this stage.
- Arrival in UAE — On arrival, immigration scans your biometrics and links them to your Unified Number.
- Residency stamping — After completing medical tests and Emirates ID registration, your residency visa is stamped. Your Unified Number appears on the visa page.
For existing residents, your Unified Number was assigned when you first obtained your UAE visa. You do not need to apply for it separately.
How to Check Your Unified Number Online
You can find your Unified Number through several methods:
Method 1: ICP Smart Services Portal (icp.gov.ae)
- Visit icp.gov.ae
- Click on “Smart Services”
- Select “Inquiry About Residency” or “Visa Inquiry”
- Enter your passport number, nationality, and date of birth
- Your current residency record — including Unified Number — will be displayed
Method 2: GDRFA Dubai App / Portal
- Download the GDRFA Dubai app or visit gdrfad.gov.ae
- Create an account or log in with UAE PASS
- Navigate to “Residency” → “Inquire”
- Enter your passport details
- Your Unified Number will appear in the result
Method 3: On Your Visa Stamping Page
If you have a UAE residency visa stamped in your passport, look at the visa sticker. The Unified Number (often labelled “ID No.” or “UID”) is printed directly on the visa page — usually a 10–15 digit number below the visa number.
Method 4: ICP App (UAE PASS)
- Download the ICP Smart Services app
- Log in with UAE PASS (linked to your Emirates ID)
- View your residency profile — Unified Number is displayed in your profile
Method 5: AMER Service Centre
Visit any AMER Centre in Dubai or ICP service centre in other emirates. Bring your passport and Emirates ID. Staff can retrieve your Unified Number immediately.
How Much Does a Unified Number Cost?
The Unified Number itself is free. It is automatically assigned as part of your visa processing. There is no separate fee to obtain or retrieve a Unified Number.
However, the visa processing fees that accompany UID assignment do carry costs:
| Service | Approximate Cost |
|---|---|
| New employment visa (entry permit) | AED 300–1,500 (varies by visa type) |
| Residency visa stamping | AED 200–500 |
| Emirates ID (linked to UID) | AED 100–370 (2-year card) |
| Retrieving UID at AMER Centre | Free to AED 30 service fee |
How Long Does It Take?
If you are a new resident, your Unified Number is assigned automatically during visa processing — typically within 3–7 working days after your entry permit is issued.
If you are an existing resident checking your UID online, the ICP portal returns results instantly. AMER Centre visits take approximately 30–60 minutes including queue time.
Common Problems with Unified Numbers and How to Fix Them
Problem 1: Unified Number Not Found on ICP Portal
Cause: Name mismatch, passport renewal (new passport not yet linked), or data entry error in the system.
Fix: Visit an ICP service centre or AMER Centre in Dubai. Bring your old and new passport plus your Emirates ID. Staff will link the records manually. Processing takes 1–3 working days.
Problem 2: Two Unified Numbers Assigned (Duplicate)
Cause: Common when a person changes nationality, has multiple passport issuances, or had a data entry discrepancy.
Fix: Submit a merge request at ICP or AMER Centre. Required documents: old and new passports, Emirates ID, sponsor’s letter (if employment visa). Processing: 3–5 working days.
Problem 3: UID Not Matching e-Channel Records
Cause: e-Channel stores records from the sponsor’s account. If your employer registered you under a different passport or name spelling, the UID may differ.
Fix: Your PRO services provider or employer must update the records in e-Channel using your correct Unified Number. See our guide on e-Channel UAE for instructions.
Problem 4: Unified Number Shows Cancelled/Inactive Status
Cause: Your visa was cancelled by a previous employer and not renewed.
Fix: New visa sponsorship reactivates the record. If in the UAE on visit visa, your new employer must process a fresh residency visa linked to your existing UID.
Problem 5: Can’t Access ICP Portal
Fix: Use UAE PASS for login — it’s the most stable method. Alternatively, use the GDRFA app if you’re in Dubai. For AMER Centres, no app is needed — bring documents in person.
Unified Number for Children and Dependants
Children added to a parent’s residence visa are also assigned Unified Numbers. For children under 15 with no passport, ICP uses the birth certificate number during registration. Once a passport is issued, the passport is linked to the existing UID.
Dependant visas (spouse, children, parents) are processed using the sponsor’s UID. The employment visa Dubai process includes UID assignment for all sponsored family members.
Employer Use of Unified Numbers
Companies and PROs use employees’ Unified Numbers to:
- Process new visa applications via e-Channel
- Transfer visa sponsorship between employers
- Register labour contracts with MOHRE
- Apply for labour cards
- Link employees’ Emirates IDs to the company’s MOHRE account
If you use professional PRO services in UAE, your PRO will handle all Unified Number-linked transactions on your behalf, reducing bureaucratic complexity significantly.
Frequently Asked Questions (FAQ)
1. Is the Unified Number the same as the Emirates ID number?
No. The Emirates ID number is on your physical ID card and changes with each card renewal. The Unified Number is a permanent immigration identifier that never changes, even across multiple visa renewals or employer changes.
2. Where can I find my Unified Number quickly?
Check your UAE visa stamping page in your passport — the UID is printed there, usually labelled “ID No.” You can also check it instantly on icp.gov.ae or via the ICP Smart Services app with UAE PASS.
3. Do I need a Unified Number to apply for a new visa?
If you already have a UAE immigration record, yes — your new visa will be processed under your existing UID. If you’re applying for a UAE visa for the first time, a new UID will be created automatically.
4. Can two people have the same Unified Number?
No. Unified Numbers are unique to each individual. If a duplication error has occurred (rare), you must report it to ICP for resolution.
5. Is the Unified Number free to obtain?
Yes. The Unified Number is assigned automatically as part of visa processing at no additional charge. Retrieval at AMER Centres or via ICP portal is also free (minor service fees may apply at some centres).
6. What happens to my Unified Number if my visa is cancelled?
Your UID remains in the ICP system permanently. It becomes inactive if your visa is cancelled and no new visa is sponsored, but when you obtain a new UAE visa in the future, the same UID is reactivated.
7. How many digits is a Unified Number?
Unified Numbers are typically 10 to 15 digits long. The exact format can vary depending on when the UID was first issued, as ICP has updated its numbering formats over the years.
8. Can I check someone else’s Unified Number?
No. For privacy reasons, only the individual themselves or an authorised sponsor/employer (via e-Channel or MOHRE portals with linked credentials) can access another person’s UID.
9. Do tourists get a Unified Number?
Visitors on short-term visas (tourist or visit visas) are also assigned Unified Numbers in the immigration system. However, this is generally an internal reference and not actively used by tourists during their stay.
10. My new passport doesn’t show my Unified Number. What do I do?
Your new passport must be linked to your existing UID. Visit an ICP service centre or AMER Centre with both old and new passports and your Emirates ID. The linkage is done on the spot.
11. Is the Unified Number the same as the ICA file number?
Not exactly. The ICA (now ICP) file number was a legacy identifier used before the UID system was standardised. In most cases, they refer to the same underlying record, but if you have both references, use the UID as the primary identifier in any current transaction.
12. My employer says my Unified Number is blocked. What does that mean?
A blocked UID usually means there is a labour or immigration violation linked to your record — such as an unresolved absence from work (absconding case), visa overstay, or unpaid fine. You will need to resolve the underlying issue through ICP, MOHRE, or GDRFA (Dubai) before your UID can be used for a new visa application. Professional PRO services can assist in clearing such blocks.
