OLEAN prefixes in area code 585

NANPA records 13 assigned NXX blocks to rate center OLEAN in area code 585, 1.9% 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. 8 holders hold those blocks, the largest being PAETEC ITEL, LLC (5), OMNIPOINT COMMUNICATIONS, INC. - NY (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (1). The earliest assignment on record here is 2002-04-03 and the most recent 2002-08-13. 13 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 code 716 – overlay codes cover the same geography, so a rate center is served by all of them.
