MCLAIN prefixes in area code 601

NANPA records 4 assigned NXX blocks to rate center MCLAIN 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MS (1), TELEPAK NETWORKS, INC. - MS (1), BANDWIDTH.COM CLEC, LLC - MS (1). The earliest assignment on record here is 2001-01-31 and the most recent 2001-01-31. 3 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 769 – overlay codes cover the same geography, so a rate center is served by all of them.
