UID Number Check UAE: Find Your Unified Number (2026)

Quick Summary: UAE unified number (UID) check

• What it is: your unified number (UID) is the permanent immigration-file number the UAE gives you the first time you enter the country. It links all your records – entry permits, visas and Emirates ID – under one identity.
• Check it in Dubai: use the official GDRFA Unified Number Inquiry Service – enter your passport number, nationality, date of birth and gender.
• Check it in the other emirates: use ICP smart services (icp.gov.ae or the UAEICP app); the UID shows inside your file-validity result.
• Fastest of all: it is already printed on your entry permit and residence visa, usually labelled “U.I.D. No.” or “Unified No.”.
• It is free. Looking up your own number is a free self-service inquiry – no official site charges to show it.

If a UAE visa form, a new employer, or a family-visa application has asked you for your “unified number” and you are not sure what that is or where to find it, this guide clears it up. The unified number – UID for short – is one of the most important pieces of identity you have in the UAE system, and it is also one of the most confused, because it sits alongside three other numbers that look similar.

Below we explain exactly what the unified number is, how it differs from your Emirates ID and visa file number, the official ways to check it in Dubai and the other emirates, and what to do if a visa application is blocked because you have ended up with two UIDs. HenryClub is an independent advisory – we can guide you through it, but your number is issued, held and shown only by the UAE government authorities (ICP and GDRFA).

What the unified number actually is

The unified number is a permanent identity number the UAE immigration system assigns to every foreigner who enters the country. It is created automatically the very first time you arrive on any visa – there is no separate form to fill in and nothing to apply for. From that moment it acts as the master key that ties together everything the government holds about you: your entry permits, every residence visa, your Emirates ID record, and your entry and exit history all sit under that single number. This is true even if you first arrived on a short visit or tourist visa – your unified number was created at that first entry and is printed on your entry permit, which is exactly why you are later asked for it when a visit visa is changed to a residence visa.

Because it is tied to you rather than to a document, the unified number does not change when your circumstances do. In practice it stays with you across visa renewals, a change of employer, a switch from a visit visa to a residence visa, and even a new passport – the same number follows you. That permanence is exactly why forms ask for it: it is the one identifier that lets ICP or GDRFA pull up your complete history in one go.

People often ask how many digits a unified number has. It is commonly a nine-digit number, but the authorities do not publish a fixed length and older or newer numbers can differ, so it is best not to rely on a specific digit count to judge whether a number is “right”. What matters is that it is the number labelled unified/UID on your own records.

Unified number vs Emirates ID, visa file number and passport

Four numbers get mixed up constantly. Here is how to tell them apart:

Rule of thumb: if a form wants a number that stays the same for you no matter which visa you are on, it wants your unified number. You can confirm your Emirates ID separately with our Emirates ID status guide.

How to find your unified number

There are three reliable routes, from fastest to most involved.

1. Read it off your own visa (fastest)

Because the UID is permanent, it is printed on your UAE entry permit and on your residence visa, usually at the top and labelled “U.I.D. No.” or “Unified No.”, sitting above the longer visa file number. If you have your visa PDF or a photo of the sticker, you already have your number – no portal or login needed.

2. Check online with the official service

Which portal you use depends on where your visa file sits – not on where you live now:

• Dubai visa → GDRFA. Open the GDRFA Unified Number Inquiry Service, enter your passport number, nationality, date of birth and gender, complete the security check, and it returns your UID. It is a free self-service inquiry and does not ask you to log in or enter an Emirates ID.
• Any other emirate → ICP. Use ICP smart services at icp.gov.ae, or the UAEICP app. Open the visa / residency inquiry – usually under the public services or inquiries section, labelled something like file validity or visa status – and search by your passport number, nationality and date of birth. Your unified number appears with the file details returned. A basic passport inquiry does not normally need a UAE PASS login; the app is often the simplest route, and ICP can help on 600 522 222.

Not sure which emirate issued your visa? Check the issuing authority or office printed on your residence visa, or go by your sponsor’s emirate. And because both lookups are free, if you are unsure you can try GDRFA first and ICP second – a “not found” on one usually just means your file sits with the other authority, not that anything is wrong.

3. Ask in person or by phone

If an online lookup returns nothing, an Amer service centre or an approved typing centre in Dubai, or an ICP customer-happiness centre in the other emirates, can pull your UID from your file – bring your passport and Emirates ID. These centres charge a small service fee for assisted help, which is normal and entirely separate from the free online self-service lookup. By phone: GDRFA Dubai on 800 5111, or the ICP call centre on 600 522 222.

What you need to check it

For the GDRFA (Dubai) lookup you need only three or four everyday details:

• Your passport number (the current one, or the one your visa was issued on).
• Your nationality.
• Your date of birth.
• Your gender, and you complete a short security check (captcha).

You do not need an Emirates ID or a UAE PASS login just to view your unified number, which is helpful if you have never held an Emirates ID or cannot find your card.

Got a new passport recently? Your unified number does not change, but your UAE file should be updated with the new passport – through GDRFA or an Amer centre in Dubai, or ICP or a typing centre in the other emirates. For the lookup, try the passport number your visa was issued on first; if that returns nothing, try your new one.

Why your unified number matters

You will be asked for the UID at almost every step of UAE immigration life, because it is the number the authorities use to find and link your file. Common moments include:

• Applying for a new residence visa, or renewing or cancelling one.
• Changing status inside the country – for example, moving from a visit visa to a residence visa.
• Sponsoring family members, so their file is correctly linked to yours.
• Applying for a Golden Visa or another long-term visa.
• Enrolling for or renewing an Emirates ID, and running visa-status checks.

Getting the number right matters because it is the thread that connects all of the above – which is also why problems with it can stop an application in its tracks.

Two unified numbers? Fixing a duplicate UID

One person is only supposed to have one UID, but duplicates do happen – usually when someone enters the UAE more than once through different ports or on separate entry permits, and the system issues a fresh number instead of matching the existing one. The problem often only surfaces later, when a new residence-visa application is returned with a reason such as “multiple UID numbers”, or when entry, exit or residency processing behaves oddly.

The fix is a UID merge, which consolidates the numbers back into a single record. It is best done before you lodge the new visa or Emirates ID application, not after it is rejected:

• Dubai: through GDRFA – at an Amer centre, or via the GDRFA Smart Services “Merge / Unmerge UID number” option.
• Other emirates: through a typing centre registered with ICP.

You are typically asked for a passport copy, copies of the old and current visas, and the cancellation paper if a previous visa was recently cancelled. The merge is often free and completed within a few working days, but the exact fee, documents and timing vary by emirate and case – so confirm the current requirements with GDRFA, ICP or an authorised centre. A related issue is a mismatched UID – for instance a number still tied to an old passport – which can also hold up a new visa until your records are updated.

Common mistakes to avoid

1. Using the wrong authority. A Dubai visa is on GDRFA; visas from the other six emirates are on ICP. Checking the wrong one can wrongly return “not found” even though your file is perfectly valid.
2. Confusing the four numbers. The UID, the Emirates ID number, the visa file number and the passport number are all different. Give the form the permanent unified number, not the visa file number.
3. Trusting an unofficial “UID checker”. Only icp.gov.ae, gdrfad.gov.ae, the UAEICP app and u.ae are official. Ignore lookalike domains and any site that asks for payment to “release” your number – the official lookup is free.
4. Assuming a digit length. There is no published fixed number of digits, so do not decide a number is wrong just because it is longer or shorter than you expected.
5. Leaving a duplicate UID until visa time. If you suspect you have two numbers, merge them first – discovering it when an application is rejected costs you far more time.

UID number check: frequently asked questions

What is a unified number (UID) in the UAE?

It is the permanent immigration identity number the UAE assigns you the first time you enter the country. It links all your immigration records – entry permits, residence visas and Emirates ID – under one identity, and it stays the same as you renew visas, change employer or even get a new passport. It is created automatically; there is nothing to apply for.

How do I check my unified number online?

If your visa is from Dubai, use the official GDRFA Unified Number Inquiry Service at gdrfad.gov.ae and enter your passport number, nationality, date of birth and gender. If your visa is from any other emirate, use ICP smart services at icp.gov.ae (or the UAEICP app) and open the visa / file-validity inquiry – your UID appears in the result. Both are free.

Where is the unified number on my visa?

It is usually printed at the top of your UAE entry permit and residence visa, labelled “U.I.D. No.” or “Unified No.”, above the longer visa file number. If you have your visa PDF or a photo of the sticker, you already have your number without needing any portal.

Is the unified number the same as my Emirates ID number?

No. The Emirates ID number is the 15-digit number on your Emirates ID card (in the form 784-YYYY-NNNNNNN-N) and only exists once you are a resident or citizen. The unified number is your immigration-file identifier and exists for anyone who has entered the UAE. The two live in different places: the Emirates ID number is on your Emirates ID card, while your unified number is printed on your entry permit and residence visa.

Does the unified number change when I renew or change my visa?

In practice, no. The unified number is tied to you, not to a single visa, so it stays the same across renewals, a change of employer, a switch from visit to residence visa, and a new passport. The visa file number, by contrast, is reissued with each new visa.

Is checking my unified number free?

Yes. Looking up your own unified number on the official GDRFA or ICP services is a free self-service inquiry. Fees only apply to actual transactions such as issuing or renewing a visa – never just to view your number. Any site charging to “reveal” your UID is not official.

What if the lookup says my UID is not found?

First check you are using the right authority – Dubai visas are on GDRFA, other emirates on ICP – and that your passport and date-of-birth details match your visa exactly. If it still does not appear, call GDRFA Dubai on 800 5111 or the ICP call centre on 600 522 222, or visit an Amer or ICP centre with your passport and Emirates ID.

I have two unified numbers – what should I do?

Have them merged into one record before you apply for a new visa or Emirates ID. In Dubai this is done through GDRFA (an Amer centre or the GDRFA Smart Services “Merge / Unmerge UID number” option); in the other emirates through an ICP-registered typing centre. You will usually need your passport copy and old and current visa copies. Fees and timing vary, so confirm the current requirements first.
