HARRISON prefixes in area code 208

NANPA records 3 assigned NXX blocks to rate center HARRISON in area code 208, 0.4% of the 785 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 TELNYX LLC (1), ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (1), XO IDAHO, INC. (1). The earliest assignment on record here is 2005-11-07 and the most recent 2005-11-07. 3 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 207, 283, 308, 327 – overlay codes cover the same geography, so a rate center is served by all of them.
