ROSENDALE prefixes in area code 845

NANPA records 3 assigned NXX blocks to rate center ROSENDALE 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 TC SYSTEMS, INC. - NY (1), VERIZON NEW YORK, INC. (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2012-03-29 and the most recent 2021-01-18. 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 274, 816, 920 – overlay codes cover the same geography, so a rate center is served by all of them.
