ALEXANDRIA prefixes in area code 318

NANPA records 60 assigned NXX blocks to rate center ALEXANDRIA in area code 318, 7.8% 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. 13 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (20), NEW CINGULAR WIRELESS PCS, LLC - GA (14), ELISKA WIRELESS VENTURES SUBSIDIARY I, LLC (7). The earliest assignment on record here is 2001-02-02 and the most recent 2021-06-29. 42 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 220, 320, 402, 582 – overlay codes cover the same geography, so a rate center is served by all of them.
