Audience: All UW

UW-IT eFax Service enables individuals or groups to send and receive faxes without needing a physical fax machine. Rather than having faxes print out, faxes are sent or received using email or by accessing a simple-to-use web page (https://fax.uw.edu/). Faxes are displayed using the PDF format and are retained for up to 30 days.

Paper and toner costs make operating physical fax machines expensive. The UW-IT eFax Service is an excellent alternative to maintaining a physical fax machine. Migrating existing campus fax numbers to eFax is seamless and easy. UW-IT can transition your existing fax number or set up a new fax number to meet your needs.

Upon request, the eFax service can also be HIPAA compliant. For a HIPAA-compliant service, faxes will be retained on the server for only 5 days and the contents of the fax will not be emailed, only a notification of a fax being received. To configure your eFax service to meet HIPAA compliance standards, please submit a request using the Telecom Help Form.

The following table describes options for receiving and sending faxes when using eFax.
