Carriers with 909 numbers

38 carriers hold the 786 central office codes assigned in 909. Frontier California INC. has the most, with 156 (20%). 560 of the codes (71%) 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.
