DOVER PL prefixes in area code 845

NANPA records 3 assigned NXX blocks to rate center DOVER PL 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 MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NY (1), VERIZON NEW YORK, INC. (1), ONVOY, LLC- NY (1). The earliest assignment on record here is 2008-11-06 and the most recent 2020-09-29. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
