Dialing 765 numbers

Who holds 765 exchanges

63 carriers hold the 725 central office codes assigned in 765. Indiana Bell Tel CO INC has the most, with 127 (18%). 582 of the codes (80%) 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.
