SILVERDALE prefixes in area code 360
NANPA records 33 assigned NXX blocks to rate center SILVERDALE in area code 360, 4.2% 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (11), QWEST CORPORATION (8), T-MOBILE USA, INC. (5). The earliest assignment on record here is 2001-01-25 and the most recent 2018-03-23. 22 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 564 – overlay codes cover the same geography, so a rate center is served by all of them.
