SILOAM SPG prefixes in area code 479

NANPA records 11 assigned NXX blocks to rate center SILOAM SPG in area code 479, 1.9% of the 569 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 BRIGHTSPEED OF NORTHWEST ARKANSAS, LLC (5), NEW CINGULAR WIRELESS PCS, LLC - IL (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (2). The earliest assignment on record here is 2001-03-08 and the most recent 2025-02-13. 10 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
