A UAE entry permit or residence visa may show a number marked “UID” or “Unified Number.” People often confuse it with the visa file number or Emirates ID number, but each serves a different purpose.
The unified number the UAE authorities assign to you is a unique immigration reference. It connects entry permits, residence visas and other immigration records under one profile. It usually stays linked to you when you renew a visa, change employers or receive a new passport.
This guide explains where to find your UID, how to check it online and what to do if you discover more than one number.
Key Takeaways
A unified number is a personal immigration reference, also called a UID number.
It is different from your Emirates ID number, visa number and application number.
The number is generally created when an entry permit or immigration record is opened for you.
You can check it through the official GDRFA Dubai Unified Number Inquiry Service.
Duplicate UID records should be corrected through the relevant immigration authority or an authorised service centre.
Your UID usually stays the same even when a visa document or sponsor changes.

What Is a Unified Number in UAE?
A unified number is a unique number used by UAE immigration authorities to identify a person within the immigration system. It is commonly called a UID number UAE or Unified Identity Number.
It can connect entry permits, visit visas, residence permits, renewals, cancellations, status changes and sponsorship records under one immigration profile.
A UID is normally generated when the immigration system creates your first qualifying entry or visa record. You do not usually apply for it as a separate service. It is assigned within the immigration process.
The UAE’s immigration and identity services are mainly handled by the Federal Authority for Identity, Citizenship, Customs and Port Security, known as ICP and by GDRFA Dubai for Dubai-issued files. Read Nexture’s practical guide to ICP Smart Services in the UAE to understand how online visa, residency and Emirates ID services are managed.
The official GDRFA Unified Number Inquiry Service describes the service as a way for customers to find their UID. The lookup form asks for passport number, nationality, date of birth and gender.
Is the UID Number Permanent?
Your unified number usually remains attached to your immigration identity. A new residence permit, visa renewal, employer or passport should not automatically create a new UID.
However, data-entry differences can sometimes result in duplicate records. For example, one visa application may use an old passport while a later application uses a new passport with a differently formatted name. In that situation, immigration records may need correction or merging.
Treat the word “permanent” with some care. Your UID is designed to remain consistent, but an authority can correct, consolidate or update records where required.
Why Is the Unified Number Important?
The unified number helps immigration authorities identify the correct person and connect related applications. You may need it directly or the system may use it during visa issuance, Emirates ID registration, cancellation, status changes, family sponsorship, investor visa processing or record correction.
A correct UID can prevent delays caused by mismatched details, especially after a passport, name spelling, nationality or sponsor changes.
The ICP states that residence permit issuance is linked to an Emirates ID application. That connection is one reason consistent immigration information matters during residency processing. The official ICP interactive services page also lists visa issuance, visa data amendment, residence-related services and identity card services in one government system.
Professional PRO services in Dubai can help businesses manage visa submissions, renewals and government documentation when several employee files are involved.
Where Can You Find Your Unified Number?
You may find your UID in several places depending on the type and age of your immigration document.
- UAE Residence Visa Copy
On some residence visa documents, it appears near the top and may be labelled “UID” or “Unified No.” Electronic documents can look different from older passport visa stickers, so check each field carefully.
- Entry Permit
Your electronic entry permit may include the unified number once an immigration record has been created. Do not confuse it with the entry permit number or file number.
- Digital Visa File
A downloaded visa or residence document may display the UID. Keep a clear PDF copy in case a service centre needs to check a mismatch.
- GDRFA or ICP Record
If you cannot find the number on your documents, check the official immigration portal linked to your file. Dubai-related records are generally handled through GDRFA Dubai. Files issued through other emirates are generally handled through ICP.
- Authorised Service Centre
An Amer centre in Dubai or an authorised service centre can help locate the record using your passport and visa details.
Your UID is not the number printed on the front of your Emirates ID card. It is also not your card application number or visa application reference.
Unified Number vs Emirates ID Number
These numbers serve different purposes.
Detail | Unified Number or UID | Emirates ID Number | Visa or Permit Number |
Main purpose | Connects immigration records | Identifies the Emirates ID holder | Identifies a particular visa or permit |
Issued through | Immigration record creation | Emirates ID issuance process | Visa or permit issuance |
Where found | Visa, entry permit or immigration system | Emirates ID card | Visa or permit document |
Does it usually change? | Usually remains the same | Remains linked to the person | May change when a new permit is issued |
Used for | Visa, residency and immigration matching | Identity verification and government services | Tracking a specific permission to enter or reside |
The UAE Government’s Emirates ID page confirms that Emirates ID is the government-issued identity card for UAE citizens and residents. A visitor may have an immigration record and UID without holding an Emirates ID because the card is tied to citizen or resident status.
How to Check Unified Number in UAE Online
The most direct public lookup option is the GDRFA Dubai Unified Number Inquiry Service.
- Visit the Official Portal
Open the official GDRFA Unified Number Inquiry Service.
Use the government domain and avoid unknown websites that ask you to upload a full passport copy for a basic lookup.
- Enter Your Personal Details
The official form asks for:
Passport number
Nationality
Date of birth
Gender
Security verification
Enter the details exactly as they appear on the passport connected to your UAE immigration record.
If you renewed your passport, try the current passport first. If the record is not found, you may need help checking whether the old passport remains attached to the file.
- View Your Unified Number
Submit the form and save the result securely.
If no UID is found, check for typing errors. A wrong date, nationality selection or passport character can stop the search from matching your record. The GDRFA page advises users to try again with the correct information or contact GDRFA on 800 5111.
For general visa tracking, the UAE Government explains that ICP handles relevant visa enquiries while GDRFA handles Dubai visa files. A person should normally have one immigration identity record, but duplicate UID numbers can appear.
Possible reasons include:
A new passport was used without linking the old record
The person’s name was entered differently
Nationality or birth details were recorded incorrectly
Old and new visa files were created separately
Records from different applications did not match
A system or typing error created a duplicate profile
Do not choose one number yourself. The immigration authority must confirm which record should remain active and whether the files need merging.
How to Resolve Duplicate UID Records
Prepare the documents that show both records belong to you. These may include:
Current passport copy
Old passport copy if available
Current and previous visa copies
Entry permits
Visa cancellation documents
Emirates ID copy
Screenshots or documents showing both UID numbers
For a Dubai file, contact GDRFA Dubai or visit an Amer centre. GDRFA’s official contact information page lists 800 5111 for callers inside the UAE and +971 4 313 9999 for callers outside the country. If issued through another emirate, contact ICP or visit an ICP-approved customer service channel. Ask for an immigration record review and explain that two UIDs appear under your details.
Avoid relying on fixed online claims about fees or processing time. The required service, charge and completion period can depend on the authority, file and correction needed.

When Do You Need a Unified Number?
Your UID may be requested or retrieved during several processes.
Visa Application or Renewal
The number connects a new application with your previous immigration history.
Emirates ID Application
Residence permit and Emirates ID processing are connected. Correct personal information across your passport, immigration record and ID application is essential.
Visa Cancellation or Status Change
During cancellation or a status change, the UID helps identify the record being updated.
Family Sponsorship
A sponsor’s immigration and identity details must match when applying for a spouse, child or parent. Nexture’s family visa services in Dubai cover entry permits, medical fitness coordination, Emirates ID registration and residence processing.
Business Setup and Investor Visa Processing
You do not always need a UAE residence visa simply to form a company. However, your immigration record becomes relevant when you apply for an investor, partner or employee residence permit.
This is particularly important when completing a Dubai company setup remotely and travelling later for immigration and identity steps.
Common Issues With Unified Number UAE Records
Wrong Passport Details
A single incorrect character can cause a failed search. Check the passport number, birth date and nationality carefully.
Multiple UID Records
Duplicate records may block or delay a new application until the immigration authority confirms the correct profile.
Mismatch Between Visa and Emirates ID Data
Different name spellings or passport information can affect linked processes. Ask the authority to correct the source record rather than repeatedly submitting the same application.
Old Visa Records Not Updated
A previous cancellation, expired visa or old passport may still be attached to your file. Carry copies of older documents when requesting a record review.
Using the Wrong Number
Applicants often enter an Emirates ID, visa file or application number where a UID is requested. Check the field label before submitting.
Applying Through the Wrong Authority
Dubai-issued visa records are generally managed through GDRFA Dubai while records from the other emirates are generally managed through ICP. Starting with the right authority can prevent unnecessary visits.
For immigration support connected to company formation, visa files or employee documentation, you can speak with a Dubai business setup consultant who understands how corporate and immigration processes interact.
Conclusion
Your unified number connects UAE entry permits, residence applications, cancellations and other visa activity to the correct immigration profile.
Keep copies of your current visa and entry documents. Check that your passport details match across applications and act quickly if you find two UID numbers. Use an official GDRFA or ICP channel when you need confirmation or correction.
