OSCEOLA prefixes in area code 417

NANPA records 3 assigned NXX blocks to rate center OSCEOLA in area code 417, 0.4% of the 711 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MO (1), BRIGHTSPEED OF EAST MISSOURI, LLC (1), RYSTEC, INC (1). The earliest assignment on record here is 2004-04-28 and the most recent 2004-11-01. 2 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 315, 402, 531, 574 – overlay codes cover the same geography, so a rate center is served by all of them.
