Carriers with 305 numbers

27 carriers hold the 784 central office codes assigned in 305. Bellsouth Telecomm INC d/b/a Southern Bell Tel & Tel has the most, with 363 (46%). 333 of the codes (42%) 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.
