New 646 telephone prefix


Effective July 2019, the University of Utah will add a new prefix to the list of those available for U telephone numbers. The additional prefix is necessary to accommodate the need for new telephone numbers assigned to U employees and offices. All current prefixes will continue to be used.

Additional prefix: 646 (e.g., 801-646-XXXX)

Existing prefixes: 213, 581, 585, 587

Whenever you reference your telephone number, please remember to always provide the full 10-digit telephone number, which includes the area code, prefix and last four digits. Providing your full number helps to prevent people from accidentally using an incorrect prefix.

If you have any questions, please contact your respective central IT help desk: UIT Campus Help Desk 801-581-4000, option 1; U Health ITS Service Desk 801-587-6000.
