EUREKA SPG prefixes in area code 479

NANPA records 7 assigned NXX blocks to rate center EUREKA SPG in area code 479, 1.2% 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. 6 holders hold those blocks, the largest being SOUTHWESTERN BELL (2), LEVEL 3 COMMUNICATIONS, LLC - AR (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (1). The earliest assignment on record here is 2003-12-30 and the most recent 2023-08-17. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
