Add, change and manage contact data and addresses in HISinOne

In this article you will learn:

  • what you need to know about the management, editing and origin of your contact data,
  • how you can edit (certain) contact data in HISinOne, add contact data or delete contact data you no longer need.

This article is intended for holders of the „Studieren“ and „Promovieren“ roles. However, the step-by-step instructions can also be applied to other roles.

Maintenance and management of the contact data

As a student, you can manage and edit your contact data using the „Contact data“ tab in the „Student Service“ function (menu „My studies“):



In other basic roles (e.g. „Guest Auditor Studies / Other“), the menu item „Edit my contact data“ is available under „User information“.

The following examples show how to proceed when managing and editing contact data.
Please note that the work steps described as examples apply in each case to postal addresses as well as telephone numbers or e-mail addresses, even if this is not explicitly described!

The e-mail address in the application purpose „(2-K) Study - Correspondence“ is transferred to myAccount as a preferred address („rufPreferredMail“), which means that it can also be used by other systems (e.g. Ilias).
The e-mail address entered in HISinOne as „(19) Reset password“ is also exported to myAccount („rufExterneMail“) and managed there as a private (external) e-mail. This data is transmitted automatically three times a day.


Starting with the summer semester 2023, newly enrolled students and newly enrolled doctoral students will automatically have a university mail account created for their university account according to the following scheme: <userID>@students.uni-freiburg.de (e.g. ab1234@students.uni-freiburg.de).

This mandatory e-mail address will be used in the future for correspondence related to enrollment at the University of Freiburg, e.g. for notifications from central systems such as HISinOne or the learning platform directly related to your learning events.

Since this email address is automatically stored as the default, it is therefore expected that this email address will be retrieved regularly.

For existing students, implementation is planned for 2024 or later.

After changing your initial password to a personal password via https://myaccount.uni-freiburg.de, you can access the mailbox online via the webmail interface https://mail.uni-freiburg.de.

As login name at the mail server please use your new mail address mentioned above, e.g. „ab1234@students.uni-freiburg.de“. Of course you can also manage the mail address via IMAP with mail clients on your smartphone or PC/notebook.

You can find more information about the university mail server at the computer center at https://www.rz.uni-freiburg.de/de/services/uniaccount/email.

Example: Removing a phone number from the application purpose „(2-K) Study - Correspondence“.

Example: Delete a phone number that has become invalid.
⇒ The telephone number 0761/123-123, to which other application purposes are assigned in addition to the application purpose „(2-K) Study - Correspondence“, is to be deleted completely.

To remove the assignments of an application purpose to the phone number, proceed as described in point 4. Repeat the individual steps for all application purposes that are assigned to the telephone number. Please note that you always have to edit the respective „Correspondence“ application purpose first before removing the assignment on the tiles of the application purposes „ - all contact data“.
