🇨🇦 Forgot your Client ID (UCI)? Don’t panic!
Your UCI (Unique Client Identifier) is an 8- or 10-digit number that looks like:
👉 0000-0000
or
👉 00-0000-0000
🔎 Where can you find it?
Check your:
📩 Letters from IRCC
🪪 PR card
📚 Study permit
💼 Work permit
📄 Other immigration documents
What if you can’t find your UCI?
If you don’t have any of these documents and you’re completing an application form, you can leave the UCI (Client ID) field blank.
⚠️ Don’t guess your UCI number.
Save this post for the next time you’re completing an IRCC application! 🇨🇦
