ELMA prefixes in area code 360

NANPA records 5 assigned NXX blocks to rate center ELMA in area code 360, 0.6% 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. 3 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (2), CENTURYTEL OF WASHINGTON, INC. DBA CENTURYLINK (2), UNITED STATES CELLULAR - WA (1). The earliest assignment on record here is 2002-08-15 and the most recent 2002-09-19. 4 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 564, 641 – overlay codes cover the same geography, so a rate center is served by all of them.
