CHESTERTON prefixes in area code 219

NANPA records 12 assigned NXX blocks to rate center CHESTERTON in area code 219, 2.4% of the 495 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. 7 holders hold those blocks, the largest being FRONTIER NORTH, INC.. - IN (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (1), BANDWIDTH.COM CLEC, LLC - IN (1). The earliest assignment on record here is 2004-08-10 and the most recent 2026-04-24. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
