LA PORTE prefixes in area code 219

NANPA records 21 assigned NXX blocks to rate center LA PORTE in area code 219, 4.2% 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. 9 holders hold those blocks, the largest being FRONTIER NORTH, INC.. - IN (6), ONVOY, LLC - IN (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (3). The earliest assignment on record here is 2002-04-30 and the most recent 2026-09-04. 15 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 281, 346, 832 – overlay codes cover the same geography, so a rate center is served by all of them.
