CUBA prefixes in area code 585

NANPA records 4 assigned NXX blocks to rate center CUBA in area code 585, 0.6% of the 676 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. 4 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - NY (1), PEERLESS NETWORK OF NEW YORK, LLC - NY (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2007-02-24 and the most recent 2021-04-02. 4 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 309, 573, 575, 716 – overlay codes cover the same geography, so a rate center is served by all of them.
