Information about the New Access Number

420 - the new access number for the University of Greifswald

From the 1st April 2017 onwards, the new access number for the telephone network of the University of Greifswald will be 420. The Alfried Krupp Wissenschaftskolleg will also receive the new access number 420. All of the personal four or five digit extension numbers will remain identical. The current access number 86 will then only be valid for University Medicine Greifswald and Student Services.

Please bare this in mind if you are planning any publications. Phone calls via the access number 86 will only be forwarded for a limited length of time.

When publishing your telephone number in the future, the hyphen after the access number should be replaced by a blank space in front of the extension number.

This format will make it easier for mobile phone users to use the telephone numbers on our internet pages. By doing so, they will be able to dial the telephone number with just one click.

Changing the access number to the University’s telephone network requires your help!

  • Inform your cooperation and communication partners in good time about the pending change to the access number.
  • Use your email signature to point out the change of number.
  • Change the telephone numbers on your webpages in good time, not only on the University website, but also on project websites or external websites that you are responsible for.
  • Please check whether you really still need a regular fax machine. The University Computer Centre will be happy to inform you about possible alternatives [de].

420 ... on the go

Why can I only contact some colleagues inside the university network via the 420? Quite simple: the first devices of the new telephone network have been installed. During a transition period there will be two telephone networks at the University. When a new device has been installed, it is in the 420 network. If the old telephone is still connected, it is in the old network 86. If you see or are told that the person you have dialled is in the other network, please dial either the 0420 or the 086 correspondingly.

Use the New Telephone Portal

Log-in to the new telephone portal for the telephone system to change the settings and functions of your new telephone. This new portal gives you access to your call lists, allows you to send faxes, set-up call forwarding, programme the function buttons and change the ringtone.

How Can I Access the University Medicine Network from the University Network?

If your new telephone has already been installed, you can only access the telephone numbers in the other network if you dial a zero and the corresponding access number.

If you are calling from the University into the University Medicine's telephone network, dial 086 XXXX.
If you are calling from University Medicine into the University network, dial 0420 XXXX.

Change Your Contact Boxes

Please remember when changing the contact details on your website that we no longer use a hyphen between the access number and the extension number. This makes sure that the number can be displayed on a mobile phone so that the number can be dialled directly over the display of various devices.
