Effective October 24, 2021, in order to complete all local calls in the 626 area code, you will need to dial (9 from campus phones) 1 + 626 + telephone number. This applies to all calls that are currently dialed with seven digits, from landlines, mobile phones, and VoIP. On and after this date, local calls dialed with only 7-digits may not be completed, and a recording will inform you that your call cannot be completed as dialed. You must hang up and dial again using the (9 from campus phones) + 1 area code and the 7-digit number. More information about 1+ 10-digit dialing can be found at https://www.fcc.gov/consumers/guides/ten-digit-dialing.
