Area Code 713 History:
Area code 713 was put into service. In 1982 area code 713 was split to form area code 409. In 1996 area code 713 was split to form area code 281. In 1999 area codes 713 and 281 were recombined and overlaid with area code 832.
Area code 346 was put into service on July 1, 2014 as an all services overlay of the existing area code overlay 832, 713 and 281.
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.
