GRANGEVL prefixes in area code 208

NANPA records 4 assigned NXX blocks to rate center GRANGEVL in area code 208, 0.5% 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. 4 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1), INLAND CELLULAR LLC (1). The earliest assignment on record here is 2003-06-16 and the most recent 2013-12-12. 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 code 986 – overlay codes cover the same geography, so a rate center is served by all of them.
