Carriers with 903 numbers

50 carriers hold the 771 central office codes assigned in 903. Southwestern Bell has the most, with 126 (16%). 524 of the codes (68%) 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.
