MARYSVILLE prefixes in area code 360

NANPA records 35 assigned NXX blocks to rate center MARYSVILLE in area code 360, 4.5% of the 786 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. 9 holders hold those blocks, the largest being ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (15), TELEPORT COMMUNICATIONS AMERICA, LLC - WA (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (6). The earliest assignment on record here is 2002-07-18 and the most recent 2007-06-01. 27 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 223, 326, 530, 564 – overlay codes cover the same geography, so a rate center is served by all of them.
