OAK HARBOR prefixes in area code 360

NANPA records 19 assigned NXX blocks to rate center OAK HARBOR in area code 360, 2.4% 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 ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (3), T-MOBILE USA, INC. (3). The earliest assignment on record here is 2001-04-16 and the most recent 2002-07-18. 12 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 419, 564, 567 – overlay codes cover the same geography, so a rate center is served by all of them.
