MONTICELLO prefixes in area code 845

NANPA records 18 assigned NXX blocks to rate center MONTICELLO in area code 845, 2.3% 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. 7 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (5), OMNIPOINT COMMUNICATIONS, INC. - NY (3), VERIZON NEW YORK, INC. (3). The earliest assignment on record here is 2002-07-24 and the most recent 2021-11-18. 17 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 217, 319, 329, 336 – overlay codes cover the same geography, so a rate center is served by all of them.
