Phone companies in area code 541

52 carriers hold the 781 central office codes assigned in 541. Qwest Corporation has the most, with 184 (24%). 508 of the codes (65%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. Numbers can move between carriers through porting, so a code's holder tells you where the block started, not where every number lives now.
