NAPPANEE prefixes in area code 574

NANPA records 6 assigned NXX blocks to rate center NAPPANEE in area code 574, 1.5% of the 403 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. 5 holders hold those blocks, the largest being T-MOBILE USA, INC. (2), LEVEL 3 COMMUNICATIONS, LLC - IN (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (1). The earliest assignment on record here is 2002-07-23 and the most recent 2024-06-24. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
