SLOCOMB prefixes in area code 334

NANPA records 4 assigned NXX blocks to rate center SLOCOMB in area code 334, 0.5% 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. 4 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AL (1), CENTURYLINK COMMUNICATIONS, LLC (1), ONVOY, LLC - AL (1). The earliest assignment on record here is 2003-02-05 and the most recent 2021-01-11. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
