SPIRITLAKE prefixes in area code 712

NANPA records 6 assigned NXX blocks to rate center SPIRITLAKE in area code 712, 0.9% of the 633 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (2), UNITED STATES CELLULAR - IA (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2006-03-08 and the most recent 2010-03-19. 3 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, 986 – overlay codes cover the same geography, so a rate center is served by all of them.
