User ID mentioned in email notification is not correct when user id generation criterion is set to [X] digit of SSN

1] Login to application as a partner and set User ID generation criterion as below from Customizer>Security.

First 2 characters of SSN.

2] Now suppose admin added first employee with SSN - 112365890, then this employee receives correct user id in email notification saying - "User ID is first two digit of SSN"
3] Now admin added second employee with SSN - 116945873, then this user also receives same email notification saying - "User ID is first two digit of SSN"

In this scenario when second employee tries to login to the application with userid "00", he is not able to login, because some random digits get appended to 00 and his user id becomes - 00152.

Expected -
We need to send this appended random digits in email notification as well so that employee come to know correct userid.
