NARROWSBG prefixes in area code 845

NANPA records 3 assigned NXX blocks to rate center NARROWSBG in area code 845, 0.4% of the 783 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 CITIZENS TELECOMM CO OF NY DBA FRONTIER COMM OF NY (1), NEW CINGULAR WIRELESS PCS, LLC - DC (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2004-03-12 and the most recent 2018-09-26. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
