DYER prefixes in area code 219

NANPA records 12 assigned NXX blocks to rate center DYER 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (3), INDIANA BELL TEL CO INC (3), LEVEL 3 COMMUNICATIONS, LLC - IN (2). The earliest assignment on record here is 2003-01-21 and the most recent 2024-01-02. 10 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 code 731 – overlay codes cover the same geography, so a rate center is served by all of them.
