WELLSVILLE prefixes in area code 585

NANPA records 12 assigned NXX blocks to rate center WELLSVILLE in area code 585, 1.8% 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. 7 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (5), VERIZON NEW YORK, INC. (2), BANDWIDTH.COM CLEC, LLC - NY (1). The earliest assignment on record here is 2001-05-21 and the most recent 2024-03-20. 11 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 234, 330, 573, 785 – overlay codes cover the same geography, so a rate center is served by all of them.
