LA GRANDE prefixes in area code 541

NANPA records 9 assigned NXX blocks to rate center LA GRANDE in area code 541, 1.1% of the 783 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 ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OR (2), CHARTER IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2001-09-18 and the most recent 2008-11-19. 8 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 458 – overlay codes cover the same geography, so a rate center is served by all of them.
