EVERTON prefixes in area code 417

NANPA records 3 assigned NXX blocks to rate center EVERTON 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 MCC TELEPHONY LLC (1), BRIGHTSPEED OF EAST MISSOURI, LLC (1), RYSTEC, INC (1). The earliest assignment on record here is 2004-11-01 and the most recent 2005-03-26. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
