How calls are dialed in 208
According to NANPA's dialing-plan data, local calls within 208 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Ten-digit local dialing means the area code is part of how customers save and recognize your number, so print it in full everywhere.
Phone companies in area code 208
64 carriers hold the 785 central office codes assigned in 208. Qwest Corporation has the most, with 186 (24%). 519 of the codes (66%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself.
