University Identity Number and User ID
When you are admitted to exchange studies or a degree programme, you will receive a University Identity Number (UIN).
The UIN consists of your birth date, followed by a letter and then three random numbers, for example 880527-T281. In most cases, the letter is a T, therefore the number sometimes is called a “T-number”. Exchange students receive this number when registering at the university. You use this number to identify yourself at the university, for example when you register for exams or request a transcript of records. Do not confuse this number with a Swedish Personal Identity Number. To receive a Swedish Personal Identity Number, you exchange the UIN by bringing a "personbevis" from the Swedish Tax Agency (Skatteverket) or a copy of a Swedish ID card to the Student Centre, which then will inform LADOK.
When you register, you will also receive a user ID (sometimes called a student ID), which starts with an S followed by the year you started your studies and four random numbers, for example S118692. You use the user ID to log in to all web services at the University.
