MIZE prefixes in area code 601

NANPA records 4 assigned NXX blocks to rate center MIZE in area code 601, 0.5% of the 783 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. 4 holders hold those blocks, the largest being TELEPAK NETWORKS, INC. - MS (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MS (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). The earliest assignment on record here is 2006-01-04 and the most recent 2006-01-04. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
