OAKDALE prefixes in area code 318

NANPA records 9 assigned NXX blocks to rate center OAKDALE in area code 318, 1.2% 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. 7 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), ELISKA WIRELESS VENTURES SUBSIDIARY I, LLC (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - LA (1). The earliest assignment on record here is 2002-04-29 and the most recent 2022-03-04. 9 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 209, 350, 402, 423 – overlay codes cover the same geography, so a rate center is served by all of them.
