BLANCHARD prefixes in area code 318

NANPA records 7 assigned NXX blocks to rate center BLANCHARD in area code 318, 0.9% 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. 4 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - GA (3), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2004-01-28 and the most recent 2022-09-02. 7 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 405, 936, 989 – overlay codes cover the same geography, so a rate center is served by all of them.
