MCKENZIE prefixes in area code 334

NANPA records 3 assigned NXX blocks to rate center MCKENZIE in area code 334, 0.4% of the 784 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 BRIGHTSPEED OF ALABAMA, LLC - SOUTHERN (1), LEVEL 3 COMMUNICATIONS, LLC - AL (1), HAYNEVILLE FIBER TRANSPORT, INC. - AL (1). The earliest assignment on record here is 2006-02-03 and the most recent 2013-08-13. 1 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 701, 731 – overlay codes cover the same geography, so a rate center is served by all of them.
