NICE prefixes in area code 707

NANPA records 4 assigned NXX blocks to rate center NICE in area code 707, 0.5% 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. 4 holders hold those blocks, the largest being PACIFIC BELL (1), BANDWIDTH.COM CLEC, LLC - CA (1), MCC TELEPHONY LLC (1). The earliest assignment on record here is 2005-07-26 and the most recent 2010-06-29. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
