Where can you see that your application status is "in process" already? Is it at ecas or they will send you email? Got my aor on the 7th but after checking it today on ECAS the latest update i can view is when they've sent my aor and the discover Canada reviewer.. haven't received anything though in the mailbox..
We family of 3(Me, Spouse and Kid), but I alone got AOR email, addressing my name. I thought, we will get three AOR with 3 different case numbers? Is it not the case?
The Xpresspost and Priority services comes with tracking so you can have signatures with it. If you are using letter-mail services, which is cheaper ( I paid $3.50 ) but you dont get any update until you get AOR. If you want to have discount on your mailing, i suggest you to open an account with canadapost by going online https://www.canadapost.ca/cpc/en/home.page and on the top right corner, you will see a link "sign in ". Click on that and then click on " register now ". Once you do that, then there will be a customer number beginning with " 000 " will be sent to your registered email address. You can use that customer number at the retail counter of canada post and they will give you some discount, minimum 5%.
You can also download your membership card with that customer number on your phone and use it in your future mailings.
That 2- looks like an internal indicator, not related to number of applicant. I have specified different email for my and my son's application in the same package.
Both got separate email with 2-* as correspondence ID.
