Understanding Your Essential Immigration Numbers
What Is Your UCI and Why It Matters
Your Unique Client Identifier (UCI) serves as your permanent digital fingerprint within Canada's immigration system. Think of it as your social security number for all immigration matters – once assigned, it follows you through every application, renewal, and status change.
The UCI appears in one of three formats:
- Four numbers, hyphen, four numbers: 1234-5678
- Eight consecutive digits: 12345678
- Ten digits with hyphens: 12-3456-7890
Here's what many applicants don't realize: you only receive a UCI after your first interaction with Canadian immigration authorities. If you're a completely new applicant, you won't have one until IRCC begins processing your file.
Decoding Your Application Number
Your application number (sometimes called a case number) is specific to each individual application you submit. Unlike your UCI, which stays with you permanently, you'll receive a new application number every time you apply for a different immigration service.
These numbers follow a consistent pattern: one letter followed by nine numbers or letters. Common examples include:
- B123456789 (visitor applications)
- EP123456789 (work permits)
- F123456789 (family class sponsorship)
Where to Find Your Numbers: Document by Document
Your Acknowledgment of Receipt (AOR) Letter
This is your golden ticket. The AOR letter or email contains both your UCI and application number in clearly labeled sections. Most applicants receive their AOR within 2-4 weeks of submitting a complete application.
💡 Pro tip: Create a dedicated email folder for all IRCC correspondence. You'll reference these documents multiple times throughout your immigration journey.
Work and Study Permits
On physical permits, look for your UCI on the right side of the document, typically below the application number. The format might appear slightly different than in other documents, but the core numbers remain consistent.
For electronic permits (eTA), check the confirmation email you received after approval. The UCI appears in the document details section.
Permanent Resident Cards and Landing Documents
Your UCI appears prominently on these documents since they represent your successful immigration to Canada. On PR cards, you'll find it near your photo. On older Landing Documents (IMM1000, IMM5292, or IMM5688), check the top section alongside your personal information.
Passport Stamps and Visa Labels
If you've received a visitor visa, work permit, or study permit stamp in your passport, your UCI typically appears in small print below the main visa information. You might need good lighting or a magnifying glass to read these clearly.
Navigating the 2026 Status Check System
Current Processing Timelines
As of January 2026, IRCC is sending Acknowledgment of Receipt confirmations for applications received during the week of October 6, 2025. This represents approximately a 12-week delay between submission and AOR – significantly longer than the 4-6 weeks typical in previous years.
What this means for your planning: don't expect to check your status online immediately after submitting your application. The waiting period for AOR has become part of the process.
Using the Client Application Status Tool
Canada's online status checker updates daily at approximately 6:00 AM Eastern Time. Here's what you need to know about accessing it effectively:
The system accepts three types of identification:
- Your UCI (most reliable)
- Your application number (backup option)
- Your passport number (least reliable, use only if others fail)
⚠️ Important: You only need to fill in ONE of these fields, not all three. Many applicants mistakenly try to enter multiple numbers, which can cause system errors.
What to Expect When Checking Status
The status tool provides four main types of updates:
- Application Received: Your file is in the system
- In Progress: Officers are actively reviewing your case
- Decision Made: A conclusion has been reached (could be positive or negative)
- Closed: Your application is complete or withdrawn
Don't panic if your status doesn't change for weeks or months. Immigration processing involves multiple stages, and officers often work on applications without updating the online system immediately.
Alternative Numbers and Backup Options
Confirmation of Permanent Residence Number
If you're checking the status of a permanent residence application, your Confirmation of Permanent Residence (COPR) number provides another access route. This number appears in the top right corner of your COPR document and starts with "T" followed by nine digits (example: T123456789).
Record of Landing Numbers
For older permanent residence cases, your Record of Landing number offers an alternative. Find this in the remarks section of your landing document – it starts with "W" followed by nine numbers (format: W 123 456 789).
Receipt Numbers (IMM 5401)
When you pay immigration fees, you receive a receipt with its own tracking number. This starts with a letter followed by nine numbers (example: B123456789) and can sometimes substitute for your main application number in the status checker.
Troubleshooting Common Problems
When Your UCI Starts With "CAN"
If your UCI begins with "CAN" followed by numbers, this indicates a temporary identifier. Your actual UCI will change to the standard 8 or 10-digit format once IRCC begins actively processing your application. This typically happens 4-8 weeks after receiving your AOR.
Multiple Applications, Multiple Numbers
Many applicants juggle several immigration applications simultaneously – perhaps a work permit extension while waiting for permanent residence. Each application receives its own number, but they all link to your permanent UCI.
Keep a simple spreadsheet tracking:
- Application type
- Submission date
- Application number
- Current status
- Expected processing time
When the Online System Isn't Working
The IRCC website experiences high traffic, especially during peak hours (9 AM - 5 PM Eastern Time). If you're having trouble accessing the status checker:
Try checking during off-peak hours (early morning or late evening) Clear your browser cache and cookies Use a different browser or device Wait 24 hours and try again – temporary system glitches resolve quickly
What Your Status Updates Really Mean
Reading Between the Lines
Immigration status updates often seem cryptic, but they follow predictable patterns. "Medical exam received" typically appears 2-4 weeks before "Background check in progress." Understanding these sequences helps you anticipate next steps.
When to Take Action
Most status changes require no action from you. However, watch for these critical updates:
- "Additional documents required"
- "Interview scheduled"
- "Medical exam required"
- "Passport request"
These updates typically include deadlines – missing them can delay or derail your application.
Planning Your Next Steps
Staying Organized Throughout the Process
Create a simple tracking system using your phone's calendar or a basic spreadsheet. Set monthly reminders to check your status, and note any changes immediately. This documentation becomes invaluable if you need to contact IRCC directly or hire legal assistance.
When to Seek Help
Consider professional assistance if:
- Your application has been "in progress" for longer than posted processing times
- You've received confusing or contradictory status updates
- The online system consistently fails to recognize your numbers
- You're approaching visa expiry dates without status updates
Remember, checking your status frequently won't speed up processing, but staying informed helps you respond quickly when action is required.
Your immigration journey involves numerous moving parts, but accessing your status information doesn't have to add stress to the process. With your UCI and application number in hand, you're equipped to monitor your progress and plan your next steps confidently. The key is knowing where to look and understanding what you're seeing – skills that will serve you well throughout your Canadian immigration experience.
FAQ
Q: What's the difference between my UCI and application number, and which one should I use to check my status?
Your UCI (Unique Client Identifier) is your permanent immigration ID that follows you through all interactions with Canadian immigration, appearing as 1234-5678 or 12345678. Your application number is specific to each individual application you submit, following formats like B123456789 or EP123456789. For status checking, your UCI is the most reliable option since it's linked to your entire immigration history. Use your application number as a backup if the UCI doesn't work. If you're a first-time applicant, you won't have a UCI until IRCC begins processing your file – in this case, use your application number once you receive your Acknowledgment of Receipt (AOR). The online status checker only requires ONE number, not both, so start with your UCI if you have one.
Q: I submitted my application months ago but still can't find my UCI or application number. Where exactly should I be looking?
Your numbers are only available after IRCC sends your Acknowledgment of Receipt (AOR), which currently takes 12 weeks as of 2026 – much longer than previous years. Check your email (including spam folders) for correspondence from IRCC containing these numbers. If you've received any physical documents like work permits or visitor visas, your UCI appears on the right side below the application number. For passport stamps, look in small print below the main visa information. If you're checking status for permanent residence, your Confirmation of Permanent Residence (COPR) number starting with "T" can substitute. Don't panic if you haven't received your AOR yet – IRCC is currently processing AORs for applications submitted in early October 2025, so significant delays are normal.
Q: The IRCC online status checker isn't recognizing my numbers. What alternative methods can I try?
First, ensure you're entering only ONE number field, not multiple ones simultaneously, as this causes system errors. If your UCI starts with "CAN," it's temporary and will change to the standard format within 4-8 weeks of receiving your AOR. Try these alternatives: your Confirmation of Permanent Residence number (starts with "T"), Record of Landing number (starts with "W"), or your receipt number from fee payments (format like B123456789). Access the system during off-peak hours (early morning or late evening) when traffic is lower. Clear your browser cache, try a different browser, or wait 24 hours for temporary glitches to resolve. If you have multiple applications, ensure you're using the correct application number for the specific case you want to check, as each application has its own unique identifier.
Q: How often does IRCC update the online status system, and what do the different status messages actually mean?
IRCC updates their Client Application Status tool daily at approximately 6:00 AM Eastern Time, but don't expect changes every day – processing involves multiple internal stages that aren't always reflected online. The four main status types are: "Application Received" (your file is in the system), "In Progress" (officers are actively reviewing), "Decision Made" (conclusion reached, could be positive or negative), and "Closed" (complete or withdrawn). Status sequences follow predictable patterns: "Medical exam received" typically appears 2-4 weeks before "Background check in progress." Critical updates requiring action include "Additional documents required," "Interview scheduled," "Medical exam required," or "Passport request" – these usually include deadlines you must meet. Remember, frequent checking won't speed up processing, but staying informed helps you respond quickly when action is needed.
Q: My application has been "In Progress" for longer than the posted processing times. Should I be concerned?
Processing delays beyond posted timelines are increasingly common in 2026, with many applications experiencing significant backlogs. "In Progress" status can remain unchanged for months while officers work on your file internally – this doesn't necessarily indicate problems. However, consider taking action if your application exceeds posted processing times by more than 25% or if you're approaching visa expiry dates without updates. Before contacting IRCC, ensure you haven't missed any requests for additional documents or medical exams, as these can pause processing. Document your timeline carefully: submission date, AOR date, status changes, and any correspondence. If you're consistently getting system errors or contradictory updates, or if urgent circumstances arise (job start dates, family emergencies), consider consulting an immigration professional. Remember that contacting IRCC directly should be reserved for genuine concerns, not routine status inquiries.
Q: I'm managing multiple immigration applications simultaneously. How can I keep track of all my different numbers and statuses?
Create a simple tracking spreadsheet with columns for application type, submission date, application number, UCI, current status, and expected processing time. Each application receives its own unique application number, but they all link to your permanent UCI once assigned. Set monthly calendar reminders to check each application's status and document any changes immediately. For complex cases like work permit extensions while waiting for permanent residence, note the interdependencies – for example, if your PR application is delayed, you may need to extend your work permit. Keep digital copies of all documents in organized folders, including AOR letters, receipts, and status screenshots. This documentation becomes crucial if you need to contact IRCC, hire legal assistance, or prove your legal status to employers. Consider using your phone's note app for quick status updates when you're checking on-the-go, then transfer important changes to your main tracking system.
