UNI

Your UNI is the user name by which you log in to almost every online service provided by Columbia. It is composed of your initials and one to four digits. For example, "jkb1234".

CUIT used to assign as few digits as possible. So if you were the first JKB, you'd get JKB1; if you were the second, you'd get JKB2; and so on. However, all new UNIs now have 4 digits. Most often, the first digit is "2".
