GREENTOWN prefixes in area code 765

NANPA records 3 assigned NXX blocks to rate center GREENTOWN in area code 765, 0.4% 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 NEW CINGULAR WIRELESS PCS, LLC - IL (1), TELEPORT COMMUNICATIONS AMERICA, LLC - IN (1), INDIANA BELL TEL CO INC (1). The earliest assignment on record here is 2002-03-12 and the most recent 2002-03-12. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
