Area Codes Required to Complete Local Calls Starting June 18

Starting June 18, 2022, you must dial 9 + 1 + the 10-digit phone number when using a Stanford phone line or the call will not complete. This is true even if the area code is the same as your own.

This change applies to telephones, softphones (Stanford Jabber or Stanford Webex), fax machines, and analog devices.

When did this begin?
You should have already made the change. The University IT (UIT) news article Change for Dialing Local Calls from Stanford Phone Numbers Coming Soon announced that starting in April you should no longer dial 9 + 7-digit local phone numbers when using Stanford phones.

What’s different now?
The transition period that began April 2, 2022, is ending.

During the transition period, calls dialed with 9 + 7-digits would complete, but you would first hear a recording reminding you of the change.  Effective June 18, calls will fail if you just dial 9 + 7-digits.  You will need to hang up and dial again using 9 + 1 + the 10-digit phone number.

Does this impact 5-digit dialing?
No, all 5-digit dialing between Stanford phone lines will continue to work as it does today.

Will my speed dials still work?
The call will fail if the “Speed Dial” number is programmed to dial 9 + 7-digits. To complete the call, you must update the stored number to dial a 9 + 1 + the 10-digit phone number. (See Cardinal Voice Services for more information on the Speed Dial feature.)

What locations are impacted?
This includes telephone lines and other devices using the Stanford phone system at all locations:

• Historic campus
• Stanford Redwood City campus
• Stanford Health Care and Stanford Health Care Alliance locations (e.g., Stanford Health Care clinics, Stanford Blood Center)
• Stanford Children’s Health and Packard Children’s Healthcare Alliance locations
• Stanford residences (e.g., dormitories, Stanford West, University Terrace, Olmstead Terrace, Welch Road)
• Remote Stanford locations (e.g., Stanford in Washington, Stanford Newark Hub)
