We use firstname.lastname with a 20 character limit. The owner can shorten or change their name, but must follow procedure. Last name can only be changed if has been legally changed and has been registered in the ERP. Name can be shortened, but must use as much of the last name as possible.

The initial value is based upon last name + first initial + tie-breaker characters, but the algorithm in use comes up with some odd choices. At any rate, the user can change their assigned username once. Usernames are not permitted to be reused. - ken On 8/16/13 9:33 AM, Shalla, Kevin wrote:
We're in the midst of changing the process for assigning new netIDs, and one consideration is the length of usernames allowed in various systems. We've currently got a maximum length of 8, and given that our plan is to never reuse netIDs, that maximum causes challenges to maintaining uniqueness and having reasonable netIDs without embedded numerals. We're considering increasing that to 24 characters. What maximum length do you have for netIDs? What is the maximum username length supported in most systems? Some cursory web searches gave me these numbers: Windows 256 Linux 32 Oracle 30 MySQL 16 SQL Server 128 Kevin Shalla Academic and Enrollment Services University of Illinois at Chicago
