HOBART prefixes in area code 219

NANPA records 8 assigned NXX blocks to rate center HOBART in area code 219, 1.6% 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. 5 holders hold those blocks, the largest being FRONTIER NORTH, INC.. - IN (4), TWILIO INTERNATIONAL, INC. (1), BANDWIDTH.COM CLEC, LLC - IN (1). The earliest assignment on record here is 2015-10-15 and the most recent 2024-01-02. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 580, 607 – overlay codes cover the same geography, so a rate center is served by all of them.
