GRANDVIEW prefixes in area code 509
NANPA records 4 assigned NXX blocks to rate center GRANDVIEW in area code 509, 0.5% of the 763 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 LEVEL 3 COMMUNICATIONS, LLC - WA (1), ONVOY, LLC - WA (1), VOIP INNOVATIONS, LLC (1). The earliest assignment on record here is 2003-01-07 and the most recent 2023-07-12. 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 codes 217, 319, 534, 682 – overlay codes cover the same geography, so a rate center is served by all of them.
