HAMMOND prefixes in area code 219
NANPA records 27 assigned NXX blocks to rate center HAMMOND in area code 219, 5.5% 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. 11 holders hold those blocks, the largest being INDIANA BELL TEL CO INC (10), NEW CINGULAR WIRELESS PCS, LLC - IL (6), ONVOY, LLC - IN (2). The earliest assignment on record here is 2001-01-04 and the most recent 2024-12-27. 19 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 217, 315, 447, 715 – overlay codes cover the same geography, so a rate center is served by all of them.
