My university was [initial][lastname][year][letter][letter]@school.com, allowing for 26^2 people to have the same initials and last name every year.

Despite having a rare last name and no twins, I was "AC".

Was it confirmed to be sequential (AA, AB, AC, …)? Because it could’ve been just a random sequence-looking pick from the available space. Sort of like getting #0003 on Discord when they still had random numbers in usernames.
