DENTON prefixes in area code 845

NANPA records 3 assigned NXX blocks to rate center DENTON 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. 2 holders hold those blocks, the largest being ONVOY, LLC- NY (2), CITIZENS TELECOMM CO OF NY DBA FRONTIER COMM OF NY (1). The earliest assignment on record here is 2004-08-20 and the most recent 2020-12-24. 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 336, 402, 406, 410 – overlay codes cover the same geography, so a rate center is served by all of them.
