This guide explains what a work permit number in Canada is, where to find it on your document, and why it matters for IRCC forms, employers, taxes, and status checks. You will also learn the difference between a work permit document number and other ID numbers, plus practical tips to avoid common mistakes when using your permit details.
What Is a Work Permit Number in Canada?
If you are looking for your work permit number Canada, you are not alone. Many foreign workers, international graduates, and spouses in Canada need this number when filling out forms, updating records, or speaking with Immigration, Refugees and Citizenship Canada (IRCC).
In simple terms, the Canada work permit number is the unique number printed on your work permit document. It helps IRCC identify your specific permit. You may need it when you extend your status, apply for a new permit, update employer records, or complete other immigration paperwork.
Your work permit is an official status document. It is different from your visa, your passport number, and your UCI. Because of this, it is important to know exactly where is work permit number shown and which number a form is asking for.
If you are still planning your move and want to explore your Canadian immigration options, understanding these document details early can save time and stress later.
Why this number matters
Your IRCC work permit number may be requested for many everyday and legal purposes, including:
- work permit extensions or changes of conditions
- permanent residence applications
- employer onboarding and compliance checks
- provincial health coverage or other service registrations
- tax, payroll, or Service Canada records
- contact with IRCC about your immigration file
For example, a worker applying through a Canadian work permit stream may later need the same permit details for a renewal, a spouse’s application, or a PR pathway. If you are moving from temporary status to permanent residence, your permit information can also support your timeline and legal status history.
Work permit number vs. UCI vs. visa number
One of the biggest areas of confusion is the difference between several numbers found on immigration documents.
Work permit number
This is the document number printed on the work permit itself. It is often called the work permit document number. On most permits, it usually begins with the letter “U” followed by numbers.
UCI
Your Unique Client Identifier is a personal number assigned by IRCC to identify you across applications. It stays with you, while your permit number changes each time a new permit is issued.
Visa number
If you needed a temporary resident visa to enter Canada, that visa has its own number. It is not the same as your work permit number.
This distinction is especially important if you hold an open work permit or if you are working under an employer-specific permit linked to an LMIA or LMIA-exempt category.
Where Is the Work Permit Number on a Canadian Work Permit?
If you are asking, where is work permit number located, the answer is usually straightforward once you know what to look for.
On a Canadian work permit, the document number is generally printed near the top right area of the document. In many cases, it starts with the letter U and is followed by nine digits. This is the number most people mean when they say find work permit number.
What the number looks like
A typical work permit document number may look like this:
- U123456789
The exact layout can vary slightly depending on when the permit was issued and the document format used by IRCC. However, the number is usually clearly labelled or placed in a prominent position.
How to find work permit number correctly
To find work permit number on your document, follow these steps:
- Take out the most recent work permit issued by IRCC.
- Look near the top of the page, especially the upper right section.
- Find the number beginning with “U”.
- Check that you are not using your UCI, passport number, or visa counterfoil number by mistake.
If you have had more than one permit, always use the number from your current valid document unless a form specifically asks for a previous permit.
What if you have a digital copy only?
Many applicants now rely on scanned copies or PDF files. If you do not have the paper document in front of you, you can usually still locate the Canada work permit number on the PDF version of the permit. Zoom in on the top section and review the labels carefully.
If your copy is blurry, damaged, or incomplete, it is best not to guess. Errors in document numbers can create delays. In that situation, you may want professional help to determine your eligibility for the next step and review your documents properly.
When You Need Your IRCC Work Permit Number
Your IRCC work permit number may be needed more often than you expect. Even if you are not applying for a new permit today, keeping this number easy to access is a smart idea.
Common situations where it is required
You may need your work permit number Canada when:
- applying to extend your stay as a worker
- changing employers or permit conditions, if eligible
- submitting a permanent residence application
- responding to an IRCC request
- completing employer HR forms
- updating provincial or federal records
This is common for workers under the Temporary Foreign Worker Program, those in the International Mobility Program, and graduates applying under the Post-Graduation Work Permit pathway.
Using your permit number for permanent residence planning
For many people, a work permit is only one step in a longer immigration journey. If you later apply through Express Entry or another PR pathway, your work history and legal status in Canada matter. Your permit details can help support accurate records of authorized work experience.
Workers in Canada may become eligible through the Canadian Experience Class, a provincial nominee programme, or other streams depending on their occupation, language test results, and background. Because every case is different, it helps to assess your immigration options before making a major application.
For students and spouses moving into work status
International students and spouses often need to understand permit numbers as they move between immigration categories. For example, someone finishing studies may apply for a work permit after graduation, while a spouse may qualify for a related open work permit. In both cases, knowing how to read IRCC documents is essential.
If you are studying or planning to study first, it may help to review options for work after graduation in Canada and understand how temporary status can lead to future immigration opportunities.
Common Mistakes When Looking for a Work Permit Document Number
Even though the number is printed on the permit, mistakes happen often. A small error can lead to confusion, delays, or returned forms.
Mixing up different document numbers
The most common mistake is entering the wrong number. Applicants may use:
- their UCI instead of the work permit number
- their passport number instead of the work permit document number
- their visa number instead of the IRCC work permit number
Always read the form carefully. If it asks for your work permit document number, use the permit number from the actual work permit.
Using an old permit number
If you extended your status, your newest permit will usually have a new number. Be sure you are using the current valid document, unless IRCC asks for a previous one.
Typing errors on online forms
When entering your Canada work permit number online, double-check each character. A single wrong digit can cause problems matching your record. It is a good idea to copy the number exactly as shown, keeping the initial letter if one appears.
What to do if you cannot find it
If you still cannot find work permit number, do not panic. Start by checking your latest permit copy, IRCC correspondence, and any scanned records you saved after approval. If the document is missing or unclear, you may need guidance before submitting any new application.
Whether you are extending status, changing categories, or planning PR, a careful review of your documents can make the immigration to Canada process smoother and less stressful.
How to Use Your Work Permit Number Correctly on Forms and Applications
Knowing where is work permit number on your document is only half the job. You also need to use it correctly. Many IRCC forms, employer records, and provincial applications ask for exact document details. If the work permit number Canada is entered incorrectly, your file may be delayed or matched to the wrong record.
Match the number exactly as shown
When a form asks for your Canada work permit number, enter it exactly as it appears on the permit. This usually means including the first letter and every digit with no spaces unless the form format adds them automatically.
Before you submit anything, check:
- you used the number from your current permit
- you entered the letter at the beginning, if shown
- you did not replace it with your UCI or passport number
- the expiry date and conditions on the permit also match your records
This is especially important if you are applying for a new permit under a LMIA-based work permit or through an LMIA-exempt work permit category, where document accuracy matters for both the worker and the employer.
When forms ask for document number instead of permit number
Some applicants worry because one form says “document number” and another says “permit number.” In most cases for a work permit, these terms refer to the same thing: the work permit document number printed on the permit itself.
If a form specifically asks for your UCI, application number, or temporary resident visa number, use those only in the correct field. Never assume all immigration numbers are interchangeable.
Keep a clear copy for future use
A practical tip is to save a high-quality scan of your current permit and store it securely. Many people need their IRCC work permit number months later for tax records, a status extension, or a permanent residence application. A clear copy makes it easier to avoid mistakes.

Work Permit Number Issues for Different Types of Workers in Canada
The need to find work permit number comes up across many work permit categories. While the location of the number is usually similar, the way it is used can depend on your status in Canada.
Open work permit holders
If you hold an open permit, such as a spouse or partner permit or a graduate permit, your work permit number still identifies the document even though it is not tied to one employer. You may need it when updating payroll records, proving your right to work, or extending your status if another option becomes available.
Many spouses rely on a spousal open work permit, while graduates often move forward through a post-graduation work permit. In both cases, the permit number is a key document detail.
Employer-specific work permit holders
If your permit is tied to one employer, occupation, or location, your Canada work permit number may be checked alongside the conditions printed on the permit. Employers may review it during onboarding or compliance steps, especially in regulated industries or where provincial employment standards apply.
Workers in agriculture, trades, hospitality, health care, and transport often need to provide this information more than once during their stay in Canada.
Workers planning permanent residence
Your temporary work status can support future immigration plans, but only if your records are accurate. If you later apply through Provincial Nominee Programmes or federal pathways, your permit history may help show that your Canadian work experience was authorized.
For example, workers targeting Ontario, British Columbia, Alberta, or Atlantic Canada may need to document legal status carefully as part of a broader immigration strategy. If you are comparing options, you can assess your immigration options based on your work history, language scores, and occupation.
What to Do If Your Work Permit Number Is Missing, Unclear, or Wrong
Sometimes the issue is not where is work permit number, but whether it can be read properly. This can happen if the permit copy is blurry, damaged, cut off, or inconsistent with other records.
If your permit copy is unclear
Start with the clearest version of your latest document. Check:
- the original paper permit, if you have it
- the PDF sent or saved after approval
- copies provided to your employer or school
- your online IRCC account for related document history
If the number is still unreadable, avoid guessing on a legal form. It is better to pause and confirm the correct details than to submit the wrong work permit document number.
If your permit details do not match your records
If your employer, Service Canada record, or another application shows a different number, review whether you renewed your permit since that record was created. A new permit usually means a new document number. This is one reason many newcomers keep a timeline of all permits, visas, and status changes.
If the issue appears to be a true error on an immigration document, you may need to seek guidance before taking the next step. Rules and correction procedures can vary depending on the type of mistake and whether the permit is still valid.
Be careful with status-sensitive applications
If you are close to expiry or preparing a new application, document mistakes can create extra stress. This is common for workers moving from temporary status to PR through the Canadian Experience Class or another pathway. Accurate permit details help support a clear immigration history.
Because immigration rules can change, always rely on current IRCC instructions for your specific form or programme. If your case is complex, professional support may help reduce avoidable errors.
Final Tips for Keeping Your Work Permit Records Organised
Your work permit number Canada is a small detail, but it plays an important role in your life in Canada. It can affect your ability to complete forms correctly, prove legal work authorization, and move forward with future immigration plans.
Here are a few simple ways to stay organised:
- save digital and paper copies of every permit you receive
- label each file with the issue date and expiry date
- keep your UCI, permit number, and passport details in a secure place
- review all application forms carefully before submitting them
- check IRCC instructions if a field asks for a specific type of number
Whether you are on your first permit or planning the next stage of your journey, understanding your IRCC work permit number can save time and prevent costly mistakes. It is one of those small details that can make the broader immigration to Canada process much smoother.
