SHELTON prefixes in area code 360

NANPA records 13 assigned NXX blocks to rate center SHELTON in area code 360, 1.7% 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. 7 holders hold those blocks, the largest being QWEST CORPORATION (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (3), LEVEL 3 COMMUNICATIONS, LLC - WA (3). The earliest assignment on record here is 2001-03-19 and the most recent 2002-04-30. 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 code 308 – overlay codes cover the same geography, so a rate center is served by all of them.
