MARKSVILLE prefixes in area code 318

NANPA records 11 assigned NXX blocks to rate center MARKSVILLE in area code 318, 1.4% of the 765 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. 6 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - LA (2), NEW CINGULAR WIRELESS PCS, LLC - GA (2). The earliest assignment on record here is 2001-08-20 and the most recent 2024-06-12. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
