Transition to Ten-Digit Dialing

This Sunday, October 24th, 2021, 82 area codes in 35 states and one U.S. territory will require callers who have been using seven-digit dialing for local numbers to start entering both the three-digit area code and the seven-digit telephone number to complete all calls, even if the intended recipient’s area code is the same area code as the originating caller.  After the transition to ten-digit dialing, local calls dialed within affected area codes using only seven-digits may not be completed, and a recording will inform callers that their call cannot be completed as dialed.  Callers must hang up and dial again using the applicable area code and the seven-digit number.
