OTTERBEIN prefixes in area code 765

NANPA records 4 assigned NXX blocks to rate center OTTERBEIN in area code 765, 0.6% of the 725 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 3 holders hold those blocks, the largest being INDIANA BELL TEL CO INC (2), TELEPORT COMMUNICATIONS AMERICA, LLC - IN (1), LEVEL 3 TELECOM OF INDIANA, LP - IN (1). 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
