Who holds 947 exchanges

18 carriers hold the 211 central office codes assigned in 947. Cellco Partnership d/b/a Verizon Wireless - Mi has the most, with 73 (35%). 211 of the codes (100%) 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.
