Changes to the 213 and 323 Area Codes

What You Need to Know

  • Starting on July 8, you will need to dial “9” plus “1” plus the full 10-digit phone number (9 + 1 + area code + 7-digit phone number) when calling an off-campus 213 or 323 phone number from your campus phone, even if you are calling from the same area code.
  • If you attempt to dial a 7-digit phone number in the 213 or 323 area code after this change goes into effect, you will hear a recording instructing you to hang up and dial again using the new “1 + area code + 7-digit number” dialing procedure.
