KEITHVILLE prefixes in area code 318

NANPA records 5 assigned NXX blocks to rate center KEITHVILLE in area code 318, 0.7% 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. 5 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA LA - LLC (1), ONVOY, LLC - LA (1), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2004-05-14 and the most recent 2024-02-06. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
