I sent my application on Aug 28th on-line.
I spoke to AADSAS today, and my # is in the 4200's... they are currently working on Mailing#: 19-20. They will send mine out with the 21st batch. They normally send one batch a week, hence the #19, 20, 21. These numbers correspond to the number of weeks since appliaction cycle started back in mid-may. So, it has been around 19-21 weeks since then. Normally, if you get an AADSAS number, then they will automatically assign you to the next available batch. I don't know how many applications are in a batch, but am guessing around 200 (based on my application # and the # batches sent out so far), it could be less or more.
A very important point about this process is, the information I mentioned above has little to do with application process of an individual, which normally takes 3-4 weeks, they will assign the applicant (after everything in the application is completed) with a mailing #. So, you could have sent your application back in June/July, and could still be on hold with AADSAS, and no batch # assigned. Batch # (or mailing #) is the lateral stage of the application process with AADSAS.
Probably!!....🙂
