Who holds 972 exchanges

32 carriers hold the 785 central office codes assigned in 972. Southwestern Bell has the most, with 306 (39%). 442 of the codes (56%) 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.
