Client Application Status cannot search my application number.

[Ukr52]

Hi All,

I landed in Canada around 12 days back and wanted to check the status of my PR card. This can be done through the link below.

However, when I punch in my UCI or Application of COPR number it says:
"We were not able to identify you using the information you provided....."

What could be the reason for that, it's been 12 days? Is there anybody else who is facing the same problem?

Any guidance will be valuable.

Thanks.
