KIRKLAND prefixes in area code 425
NANPA records 80 assigned NXX blocks to rate center KIRKLAND in area code 425, 12.7% of the 628 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. 14 holders hold those blocks, the largest being ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (38), LEVEL 3 COMMUNICATIONS, LLC - WA (11), TELEPORT COMMUNICATIONS AMERICA, LLC - WA (6). The earliest assignment on record here is 2001-03-30 and the most recent 2024-01-09. 38 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 779, 815, 940 – overlay codes cover the same geography, so a rate center is served by all of them.
