ALEXANDRIA prefixes in area code 320

NANPA records 18 assigned NXX blocks to rate center ALEXANDRIA in area code 320, 3.5% of the 511 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. 8 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MN (5), CENTURYLINK OF MINNESOTA, INC. (4), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2001-08-21 and the most recent 2021-03-05. 8 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, 318, 402, 582 – overlay codes cover the same geography, so a rate center is served by all of them.
