POLLOCK prefixes in area code 318

NANPA records 3 assigned NXX blocks to rate center POLLOCK in area code 318, 0.4% 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. 3 holders hold those blocks, the largest being ONVOY, LLC - LA (1), CSC VOICE, LLC (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). 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 codes 605, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
