RICHLAND prefixes in area code 509
NANPA records 17 assigned NXX blocks to rate center RICHLAND in area code 509, 2.2% 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. 7 holders hold those blocks, the largest being ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (9), ONVOY, LLC - WA (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (2). The earliest assignment on record here is 2001-12-11 and the most recent 2024-03-05. 10 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 229, 269, 319, 430 – overlay codes cover the same geography, so a rate center is served by all of them.
