UCI tracker showing 'invalid information' shortly after a UCI update

Documents Needed

  • UCI (Unique Client Identifier)

    May take more than 24 hours to fully update in the online tracker system after a change.

Step-by-Step

An applicant with a Canadian Experience Class application (AOR in May) got a UCI update but found the tracker rejected their login with 'invalid information' the very next day.

What the group suggested:
  • This is a common, temporary issue — it can take more than 24 hours for a UCI update to fully propagate through IRCC's systems, so the tracker may not recognize your details right away.


Practical takeaway:
  • If your tracker login fails right after a UCI update, wait at least a full day before trying again rather than assuming something is wrong with your application.

  • Keep your AOR date and UCI handy so you can retry the tracker login once the system catches up.

Dos, Don'ts & Tips

  • Tip: If the online tracker shows 'invalid information' right after a UCI update, wait 24+ hours before trying again — it's usually a system sync delay, not an application problem.
