Area Code 621

Area Code 621 History:

Not yet in Service
The Public Utilities Commission of Texas has approved area code 621 as an all services overlay of area codes 281,346,713 and 832. Area code 621 will only become available to subscribers when all assignable central office codes in area codes 281,346,713 and 832 are assigned. The earliest date area code 621 will be put into service is January 23, 2025. Ten digit dialing (area code + seven digit number) will be necessary in the 281,346,621,713 and 832 overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.

Ten digit dialing (area code + seven digit number) is already necessary in the overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
