How to Place Calls from Stanford Telephones

Starting in April 2022, you can no longer dial 7-digit local phone numbers when using the Stanford phone system. For details, see Change for Dialing Local Calls from Stanford Phone Numbers Coming Soon.

Emergency calls

To reach 9-1-1 emergency services

Dial 9 + 911.

Local area calls

To reach another Stanford telephone

Dial the last five digits of the telephone number.
For example, if the number is 725-4357, dial 5-4357.

Note: The Stanford system serves the University, the Medical Center, and on-campus student residences. Stanford phones have 10-digit numbers beginning with area code and 497, 498, 721, 723, 724, 725, or 736 (e.g., 650-725-4357). Note that from a non-Stanford phone, a caller must dial your full 10-digit phone number to reach you; non-Stanford callers cannot dial a five-digit number to reach you.

To reach an off-campus phone within the local area (all area codes including 650)

Dial 1 + area code + seven-digit telephone number.
 

Long distance calls

Area code 650 outside the local area

Dial 1 + 650 + seven-digit telephone number

Outside 650 within the U.S. and Canada
