MT HOME prefixes in area code 870

NANPA records 13 assigned NXX blocks to rate center MT HOME in area code 870, 1.7% of the 785 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. 6 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (4), BRIGHTSPEED OF NORTHERN ARKANSAS, LLC (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (2). The earliest assignment on record here is 2002-10-03 and the most recent 2014-06-05. 4 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 208, 327, 830, 986 – overlay codes cover the same geography, so a rate center is served by all of them.
