A couple of people recently pinged me to say that they have received a 10 digit UCI. When one of them asked the IRCC operator as to why the UCI is 10 digits long, he was told that the 8 digit UCI is now exhausted and so 10 digit UCI will be used henceforth.malican said:I applied under PNP .Only number i have is Application number in the ack document.It starts with E*****.
I was reading the http://www.visafile.info/how-to-find-your-file-number/ and it says my number should start with EP*****.
The UCI # is 4 numbers hyphen four numbers. As in 0000-0000. If you ever applied for a Canadian visa you would find it on your acknowledgement letters. And the application # would be your express entry profile #.
