ARCADIA prefixes in area code 318

NANPA records 6 assigned NXX blocks to rate center ARCADIA in area code 318, 0.8% 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 BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - LA (2), CP-TEL NETWORK SERVICES, INC. - LA (1). The earliest assignment on record here is 2001-12-19 and the most recent 2021-01-29. 5 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 308, 405, 419, 567 – overlay codes cover the same geography, so a rate center is served by all of them.
